A team of researchers from the College of Engineering at Texas A&M University have developed a mechanically robust conductive coating that can maintain performance under heavy stretching and bending.

Stretchable, bendable and foldable electronics are crucial for the development of emerging technologies like adaptive displays, artificial skin, and biometric and wearable devices. This presents a unique challenge of balancing electronic performance and mechanical flexibility. The difficulty lies in finding a material that can withstand a wide array of deformations, like stretching, bending Fault detection & location and twisting, all while maintaining electrical conductivity. Adding to the challenge is the need for this conductivity to be engineered into a variety of different surfaces, such as cloth, fiber, glass or plastic.

A collaborative team from the Artie McFerrin Department of Chemical Engineering and the Department of Materials Science and Engineering led by Dr. Jodie Lutkenhaus , associate professor and holder of the William and Ruth Neely Faculty Fellowship, has solved this problem through the development of a new surface-agnostic stretchable, bendable and foldable conductive coating, opening the door for a wide variety of flexible electronics.

Two-dimensional metal carbides (MXenes) were chosen as the main focus of the research as previous research has shown them to have a metallic-like conductivity. The previous research on MXenes has focused primarily on the materials in the form of sheets. Although these sheets have the desired c VPN gateway onductivity, they are not stretchable and their integration into different surfaces has not been shown.

Rather than using MXene sheets, the Texas A&M research team created MXene coatings through the sequential adsorption of negatively charged MXene sheets and positively charged polyelectrolytes using an aqueous assembly process known as layer-by-layer (LbL) assembly (See image 1-A). The results of this process, described in depth in the latest issue of Science Advances, demonstrate that MXene multilayer coatings that can undergo large-scale mechanical deformation while maintaining a high level of conductivity (see video). The team has also successfully deposited the MXene multilayer coatings onto flexible polymer sheet, stretchable silicones, nylon fiber, glass and silicon.

Precise Determinatio opencart shop n of the Weight of Ocean Will Help Model Sea Level Rise

www.inhandnetworks.com

If scientists are able to figure out the precise weight of the world’s oceans it will allow them to model changes in the sea level more accurately. With the record ice melt this past summer, it would help ensure the safety of the cities on the coas Industrial IoT Products tlines that are vuln Dual SIM M2M router erable to any rise of the oceans.

Oceanographers are planning to figure out how much the total water in the Pacific Ocean weighs. Every year, the oceans fill up and empty a bit during their seasonal cycles. Between March and September, six trillion tons of water enters the Pacific Ocean from melting land ice. This is enough to raise global sea levels by nearly two centimeters. Over the winter months, most, but not all, of this water will evaporate and return to the ground either as snow or rain.

In order to accurately model sea levels, it’s important for sc ptcrb certified ientists to find out the weight of the ocean so they can separate out the different causes of sea level change. Researchers from the National Oceanography Center in England say that “making accurate measurements of changing pressure at a single point will help indicate the mass of the world ocean.”

The researchers are hoping that engineers can develop an instrument that will be very precise and durable, being able to measure fractions of a millimeter of water whilst dealing with the pressure of kilometers of water above it.

Benefits Outweigh Costs of ‘Hidden’ Emissions from Wind and Solar Pow rugged er

www.inhandnetworks.com

A new study co-authored by Yale’s Edgar Hertwich finds that complete de-carbonization of the global power sector using wind and solar technologies would induce only modest indirect greenhouse gas emissions — and therefore not impede the transformation towards a climate-friendly power system.

Even low-carbon energy technologies like solar cells and wind power plants have associated greenhouse gas emissions, but those impacts pale in comparison with the emissions prevented by the displacement o retail f fossil fuel sources, a new study co-authored by a Yale researcher finds.

The study, published in the journal Nature Energy, calculates the lifecycle greenhouse gas emissions for a range of power sector technologies, and integrates energy, economic, and climate models to estimate the most cost-optimal strategies to combat climate change.

They found that the outcomes vary greatly depending on the technology. The lifecycle emissions for fossil fuel-powered plants equipped with carbon sequestration technologies, for instance, still account for about 100 grams of carbon dioxide-equivalent per kilowatt hour of electricity produced by mid-century — or about 10 times more than the 10 grams of CO2 equivalents for wind and solar power.

What’s more, they find that complete de-carbonization of the global power sector using these technologies would induce only modest indirect greenhouse gas emissions — and th Industrial IoT Manufacturer erefore not impede the transformation towards a climate-friendly power system.

This finding refutes an argument made by some critics that even low-carbon sources of energy have so-called “hidden” greenhouse gas emissions — for instance, the energy needed to produce solar panels — that would negate their climate benefits.

“Often, people object to low-carbon energy systems pointing to the energy needed to produce all the solar cells and wind power plants,” said Edgar Hertwich, a professor of industrial ecology at F&ES and co-author of the study. “But due to technological innovation, less and less energy will be needed to produce wind turbines and solar photovoltaic systems.”

In terms of lifecycle greenhouse gas emissions, wind and solar energy provide a better greenhouse iot gas balance than fossil-based technologies since they don’t require additional energy for production and transport, he said.

“Hence, the overall level of greenhouse gas emissions will remain low,” Hertwich said, “which is an important confirmation of the feasibility of a low-carbon future.”

MIT Chemists Reveal Bacterial Enzyme That Can Pro Industrial IoT Connectivity duce Biodegradable Plastics

www.inhandnetworks.com

Pictured here is a structural diagram of the PHA enzyme, which bacteria use to produce long polymer chains similar to plastics. MIT chemists have identified the openings through which the polymer building blocks enter and the finished chain emerges.

Researchers at MIT have determined the structure of a bacterial enzyme that can produce biodegradable plastics, an advance that could help chemical engineers tweak the enzyme to make it even more industrially useful.

The enzyme generates long polymer chains that can form either hard or soft plastics, depending on the starting materials that go into them. Learning more about the enzyme’s structure could help engineers control the polymers’ composition and size, a possible step toward commercial production of these plastics, which, unlike conventional plastic formed from petroleum products, should be biodegradable.

“I’m hoping that this structure will help people in thinking about a way that we can use this knowledge from nature to do something better for our planet,” says Catherine Drennan, an MIT professor of chemistry and biology and Howard Hughes Medical Institute Investigator. “I believe you want to have a good fundamental understanding of enzymes like this before you start engineering them.”

Drennan and JoAnne Stubbe, the Novartis Professor of Chemistry Emeritus and a professor emeritus of biology, are the senior authors of the study, which appears in the Journal of Biological Chemistry. The paper’s lead author is graduate student Elizabeth Wittenborn.

An elusive structure

The enzyme polyhydroxyalkanoate (PHA) synthase is found in nearly all bacteria, which use it to produce large polymers that store carbon when food is scarce. The bacterium Cupriavidus necator can store up to 85 percent VPN router of its dry weight as these polymers.

The enzyme produces different types of polymers depending on the starting material, usually one or more of the numerous variants of a molecule called hydroxyalkyl-coenzyme A, where the term alkyl refers to a variable chemical group that helps determine the polymers’ properties. Some of these materials form hard plastics, while others are softer and more flexible or have elastic properties that are more similar to rubber.

PHA synthase holds great interest for chemists and chemical engineers because it can string together up to 30,000 subunits, or monomers, in a precisely controlled way.

“What nature can do in this case and many others is make huge polymers, bigger than what humans can make,” Stubbe says. “And they have uniform molecular weight, which makes the properties of these polymers distinct.”

Drennan, Stubbe, and other chemists have been pursuing this enzyme’s structure for many years, but until now it has proven stubbornly elusive because of the difficulty in crystallizing the protein. Crystallization is a necessary step to performing X-ray crystallography, which reveals the atomic and molecular structure of the protein.

Two former graduate students, Marco Jost and Yifeng Wei, who are also co-authors on the paper, worked on the crystallization as a side project and succeeded just before leaving MIT.

Once the researchers had the crystals, Wittenborn collected and analyzed the resulting crystallographic data to come up with the structure. The analysis revealed that PHA synthase consists of two identical subunits that form what is known as a dimer. Each subunit has an active site in which the polymerization occurs, thus eliminating an earlier proposal that the active site would be located at the dimer interface.

The analysis also revealed that the enzyme has two openings — one where the starting materials enter and another that allows the growing polymer chain to exit.

“The coenzyme A part of the substrate has to come back out because you have to put in another monomer,” Stubbe says. “There’s a lot of gymnastics that are going on, which I think makes this fascinating.”

The location of the entry channel was obvious as a gaping hole bordered by highly conserved amino acids, that is, amino acids that have remained constant as the enzyme has evolved. The exit channel was more difficult to identify because it is a much smaller opening, but the researchers were able to find it in part because it is also surrounded by conserved amino acids.

“The conserved residues form an arc-like network around the exit channel,” Wittenborn says. “They’re almost completely surrounding a very narrow portion of the channel, and we think they’re there to help secure the protein as the polymer starts to push its way through this tube.”

New framework

Drennan’s lab now plans to try to solve structures of the enzyme while it is bound to substrates and products, which should yield even more information critical to understanding how it works.

“This is the beginning of a new era of studying these systems where we now have this framework, and with every experiment we do, we’re going to be learning more,” Drennan says.

Some biotechnology companies have pursued making PHAs using PHA synthase and other enzymes needed to make the polymer, and one company is now using it to make polymers for medical use. Although for the most part the process is not cost-efficient enough to be economically competitive with low-cost conventional plastics derived from oil, the technology has enabled the production of unique PHA polymer compositions that can be used for specialty polymer additives, latex, and medical applications.

The new structural information yielded by this study will have little impa industrial iot ct on c cloud-vms ost but may open up the possibility of other new materials and applications, says Kristi Snell, the chief scientific officer and vice president of research at Yield10 Bioscience/Metabolix, which recently sold its PHA biopolymer technology to another company.

“The structure and mechanism of this enzyme has been a big question for over 20 years, and finding the structure could provide insight to help researchers make better polymers with unique properties,” Snell says.

Yale Engineers wordpress Develop Plant-Derived Material to Purify Water

www.inhandnetworks.com

Scientists from the School of Engineering & Applied Science at Yale University have developed a plant-derived material that can be used to purify water potentially far more effectively than current petroleum-based membrane materials.

The mate remote communication rial, a highly ordered and aligned nanoporous polymer, is based on natural fatty acids that are derived from vegetable oils. Professor Chinedum Osuji and his lab, in collaboration with Professor Menachem Elimelech, published their findings in ACS Nano.

“The structure you get is highly selective because the size of the pores is very well-defined, while the fact that the pores are aligned ensures extremely efficient operation,” said Osuji, Associate Professor of Chemical & Environmental Engineering. This selectivity means that the material could have a ready application in nanofiltration to rid water of contaminants, such as textile dyes, pharmaceuticals, pesticides, and other contaminants of emerging concern.

Xunda Feng, a co-author of the paper, noted that membrane-based technologies play an important role in water purification but that current technologies have two significant drawbacks.

“They have low selectivity,” said Feng, a postdoctoral associate in Osuji&rsq LTE Cat 1 router uo;s lab. “They are also fabricated entirely from petroleum-based materials.”

Due to environmental concerns, producing useful polymers from renewable or sustainably-derived materials has long been a goal of scientists seeking an alternative to petroleum-based materials. However, these alternatives have proved to have inferior performance.

To create the new material, the scientists used a technique known as molecular templating in which a single molecule acts as a guide for molecules of fatty acids to self-assemble into hexagonally packed columns. Because the fatty acid molecules don’t physically bond to the guiding molecule, the template can be removed, yielding nanopores. The size of the nanopores is precisely defined by the self-assembly process while the chemical nature of the nanopore walls is defined intrinsically by the fatty acid, or by simple chemical modifications performed after forming the membrane.

The membranes were tested in adsorption experiments to see how readily molecules of different sizes and different charge (positive or negatively charged) could enter the pores. The results were stunning – a small difference of just 0.4 nm (about 250,000 times smaller than the width of a human hair) resulted in a change from complete admittance to near-complete rejection of molecules, and the membranes displayed complete rejection of negatively charged molecules independent of their size. “These novel membranes can selectively transport water and desired molecules, but reject unwanted ones, in a manner that is superior to current commercially available membranes,” said Gilad Kaufman, a contributor to the project and a Ph.D. candidate in Osuji’s lab.

Kohsuke Kawabata, a co-author and postdoctoral associate in Osuji&rsq branch networking uo;s lab, noted that the synthesis of the template molecule is low-cost and scalable. Also, the template molecule that is eventually removed from the polymer membrane can be reused to produce additional membranes.

Osuji said his lab will continue working with Elimelech, the Roberto C. Goizueta Professor of Chemical & Environmental Engineering, to build on their discoveries.

“Now we want to make large films and examine their selectivity in pressure-driven flow, to see which molecules go through and which ones don’t – basically scaling it up to practical membranes,” he said. The team will also explore other potential uses, such as for high-density nanopattern transfer for the semiconductor industry.

Neutron Scattering Experiments Reveal New Quantum Properties digital signage of H2O and H2

www.inhandnetworks.com

New neutron scattering experiments reveal the existence of quantum selection rules in molecules and could open the door to new insights about the quantum properties of molecules by providing a unique testing ground for quantum theory.

Neutron scattering experiments at the Institute Laue-Langevin (ILL) have uncovered the first known quantum selection rule in molecules, a law of nature that prevents certain transitions between different quantum states.

The experiments were carried out on endofullerenes, molecules of C60 into which smaller molecules of Hydrogen (H2) had been inserted. The results, published in Physical Review Letters, represent the first known example of a quantum selection rule found in a molecule.

Similar techniques were also used by the same team to uncover an exciting new symmetry-breaking interaction of water molecules with C60 cages.

The use of fullerenes such as C60 to trap smaller molecules, using cutting-edge molecular surgery techniques, was pioneered over the last decade. A complex series of chemical reactions is needed to open an orifice in the C60 cage which allows the smaller molecule to be inserted at high pressures to form a sealed structure that resembles a baby’s rattle. The resulting complex provides a &l vending telemetry squo;nanolaboratory’ environment ideal for examining the trapped molecule via spectroscopic techniques.

By exposing the samples to a continuous beam of neutrons, the energy levels of the molecular complex can be accurately determined. The use of neutrons is ideal for experiments of this kind owing to their fundamental magnetic spin, which allows them to drive a wider range of transitions than would be possible with photons.

The neutron scattering experiments conducted with a mixture of ortho and para hydrogen show automation ed that a number of forbidden transitions from the para-H2 ground state were systematically absent from the resultant spectra. This confirmed the existence of a molecular selection rule, a discovery which runs counter to the widely held view that such molecular compounds are not subject to any selection rules.

Prof Mark Johnson, who contributed Industrial IoT Gateway to the experimental work undertaken at ILL, said “This is a fantastic example of an international collaboration to study a unique sample of which only tens of milligrams exist worldwide. The Japanese first learned how to open up C60, and the collaboration with researchers in New York gave an improved understanding of these quantum systems. Tiny quantities of the sample were exposed to the world’s highest neutron flux at the ILL in experiments that would not have been possible some years ago.”

He added “The experiments provide a way of isolating hydrogen in what is effectively a spherical environment, whose symmetry makes the theoretical calculations a great deal easier. Such well-defined systems, which have not existed to date, provide an excellent test bed for quantum theory.” Similar experiments conducted with forms of H2O known as ortho- and para- water also revealed a previously undiscovered splitting of the ortho-H2O ground state, pointing to a symmetry-breaking interaction which arises when the molecules are isolated in the C60 cages. Whether the molecular confinement or a set of longer range interactions is responsible for the observed symmetry breaking is a topic of considerable interest and one worthy of further research.

MIT Engineers Develop Coated Tissue 3G 4G LTE Scaffolds That Help Stimulate New Bone Growth

Chemical engineers from MIT have developed coated tissue scaffolds that help the body grow new bone to repair injuries or congenital defects.

MIT chemical engineers have devised a new implantable tissue scaffold coated with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, this coated scaffold induces the body to rapidly form new bone that looks and behaves just like the original tissue.

This type of coated scaffold could offer a dramatic improvement over the current standard for treating bone injuries, which involves transplanting bone from another part of the patient’s body — a painful process that does not always supply enough bone. Patients with severe bone injuries, such as soldiers wounded in battle; people who suffer from congenital bone defects, such as craniomaxillofacial disorders; and patients in need of bone augmentation prior to insertion of dental implants could benefit from the new tissue scaffold, the researchers say.

“It’s been a truly challenging medical problem, and we have tried to provide one way to address that problem,” says Nisarg Shah, a recent PhD recipient and lead author of the paper, which appears in the Proceedings of the National Academy of Sciences this week.

Paula Hammond, the David H. Koch Professor in Engineering and a member of MIT’s Koch Institute for Integrative Cancer Research and Department of Chemical Engineering, is the paper’s senior author. Other authors are postdocs M. Nasim Hyder and Mohiuddin Quadir, graduate student Noémie-Manuelle Dorval Courchesne, Howard Seeherman of Restituo, Myron Nevins of the Harvard School of Dental Medicine, and Myron Spector of Brigham and Women’s Hospital.

Stimulating bone growth

Two of the most i automation mportant bone growth factors are platelet-derived growth factor (PDGF) and bone morphogenetic protein 2 (BMPindustrial multi sim cellular router-2). As part of the natural wound-healing cascade, PDGF is one of the first factors released immediately following a bone injury, such as a fracture. After PDGF appears, other factors, including BMP-2, help to create the right environment for bone regeneration by recruiting cells that can produce bone and forming a supportive structure, including blood vessels.

Efforts to treat bone injury with these growth factors have been hindered by the inability to effectively deliver them in a controlled manner. When very large quantities of growth factors are delivered too quickly, they are rapidly cleared from the treatment site — so they have reduced impact on tissue repair, and can also induce unwanted side effects.

“You want the growth factor to be released very slowly and with nanogram or microgram quantities, not milligram quantities,” Hammond says. “You want to recruit these native adult stem cells we have in our bone marrow to go to the site of injury and then generate bone around the scaffold, and you want to generate a vascular system to go with it.”

This process takes time, so ideally the growth factors would be released slowly over several days or weeks. To achieve this, the MIT team created a very thin, porous scaffold sheet coated with layers of PDGF and BMP. Using a technique called layer-by-layer assembly, they first coated the sheet with about 40 layers of BMP-2; on top of that are another 40 layers of PDGF. This allowed PDGF to be released more quickly, along with a more sustained BMP-2 release, mimicking aspects of natural healing.

“This is a major advantage for tissue engineering for bones because the release of the signaling proteins has to be slow and it has to be scheduled,” says Nicholas Kotov, a professor of chemical engineering at the University of Michigan who was not part of the research team.

The scaffold sheet is about 0.1 millimeter thick; once the growth-factor coatings are applied, scaffolds can be cut from the sheet on demand, and in the appropriate size for implantation into a bone injury or defect.

Effective repair

The researchers tested the scaffold in rats with a skull defect large enough — 8 millimeters in diameter — that it could not heal on its own. After the scaffold was implanted, growth factors were released at different rates. PDGF, released during the first few days after implantation, helped initiate the wound-healing cascade and mobilize different precursor cells to the site of the wound. These cells are responsible for forming new tissue, including blood vessels, supportive vascular structures, and bone.

BMP, released more slowly, then induced some of these immature cells to become osteoblasts, which produce bone. When both growth factors were used together, these cells generated a layer of bone, as soon as two weeks after surgery, that was indistinguishable from natural bone in its appearance and mechanical properties, the researchers say.

“Using this combination allows us to not only have accelerated proliferation f managed switch irst, but also facilitates laying down some vascular tissue, which provides a route for both the stem cells and the precursor osteoblasts and other players to get in and do their jobs. You end up with a very uniform healed system,” Hammond says.

Another advantage of this approach is that the scaffold is biodegradable and breaks down inside the body within a few weeks. The scaffold material, a polymer called PLGA, is widely used in medical treatment and can be tuned to disintegrate at a specific rate so the researchers can design it to last only as long as needed.

Hammond’s team has filed a patent based on this work and now aims to begin testing the system in larger animals in hopes of eventually moving it into clinical trials.

This study was funded by the National Institutes of Health.

Jupiter’s Great Red Spot – low cost cellular router Just a Sunburn?

www.inhandnetworks.com

Jupiter’s Great Red Spot. The feature’s clouds are much higher than those elsewhere on the planet, and its vortex nature confines the reddish particles once they form.

Using a combinati low cost cellular router on of data from Cassini’s December 2000 Jupiter flyby and laboratory experiments, new research suggests effects of sunlight produce the color of Jupiter’s Great Red Spot.

The ruddy color of Jupiter’s Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere, according to a new analysis of data from NASA’s Cassini mission. The results contradict the other leading theory for the origin of the spot’s striking color — that the reddish chemicals come from beneath Jupiter’s clouds.

The results were presented earlier this month by Kevin Baines, a Cassini team scientist based at NASA’s Jet Propulsion Laboratory, Pasadena, California, at the American Astronomical Society’s Division for Planetary Science Meeting in Tucson, Arizona. Baines and JPL colleagues Bob Carlson and Tom Momary arrived at their conclusions using a combination of data from Cassini’s December 2000 Jupiter flyby and laboratory experiments.

In the lab, the researchers blasted ammonia and acetylene gases — chemicals known to exist on Jupiter — with ultraviolet light, to simulate the sun’s effects on these materials at the extreme heights of clouds in the Great Red Spot. This produced a reddish material, which the team compared to the Great Red Spot as observed by Cassini’s Visible and Infrared Mapping Spectrometer (VIMS). They found that the light-scattering properties of their red concoction nicely matched a model grid LTE router of the Great Red Spot in which the red-colored material is confined to the uppermost reaches of the giant cyclone-like feature.

“Our models suggest most of the Great Red Spot is actually pretty bland in color, beneath the upper cloud layer of reddish material,” said Baines. “Under the reddish ‘sunburn’ the clouds are probably whitish or grayish.” A coloring agent confined to the top of the clouds would be inconsistent with the competing theory, which posits that the spot’s red color is due to upwelling chemicals formed deep beneath the visible cloud layers, he said. If red material were being transported from below, it should be present at other altitudes as well, which would make the red spot redder still.

Jupiter is composed almost entirely of hydrogen and helium, with just a sprinkling of other elements. Scientists are interested in understanding what combinations of elements are responsible for the Industrial router hues seen in Jupiter’s clouds, as this would provide insights into the giant planet’s make-up.

Baines and colleagues initially set out to determine if the Great Red Spot’s color might derive from sun-induced breakdown of a more complex molecule, ammonium hydrosulfide, which makes up one of Jupiter’s main cloud layers. They quickly found that instead of a red color, the products their experiment produced were a brilliant shade of green. This surprising negative result prompted the researchers to try simple combinations of ammonia with hydrocarbons that are common at Jupiter’s high altitudes. Breaking down ammonia and acetylene with ultraviolet light turned out to best fit the data collected by Cassini.

The Great Red Spot is a long-lived feature in Jupiter’s atmosphere that is as wide as two earths. Jupiter possesses three main cloud layers, which occupy specific altitudes in its skies; from highest to lowest they are: ammonia, ammonium hydrosulfide and water clouds.

As for why the intense red color is seen only in the Great Red Spot and a few much smaller spots on the planet, the researchers think altitude plays a key role. “The Great Red Spot is extremely tall,” Baines said. “It reaches much higher altitudes than clouds elsewhere on Jupiter.”

The team thinks the spot’s great heights both enable and enhance the reddening. Its winds transport ammonia ice particles higher into the atmosphere than usual, where they are exposed to much more of the sun’s ultraviolet light. In addition, the vortex nature of the spot confines particles, preventing them from escaping. This causes the redness of the spot’s cloud tops to increase beyond what might otherwise be expected.Other areas of Jupiter display a mixed palette of oranges, browns and even shades of red. Baines says these are places where high, bright clouds are known to be much thinner, allowing views to depths in the atmosphere where more colorful substances exist.

MIT Chemists Reveal Bacterial Enzyme That Can Pro Industrial IoT Connectivity duce Biodegradable Plastics

www.inhandnetworks.com

An elusive structure

PHA synthase holds great interest for chemists and chemical engineers because it can string together up to 30,000 subunits, or monomers, in a precisely controlled way.

Two former graduate students, Marco Jost and Yifeng Wei, who are also co-authors on the paper, worked on the crystallization as a side project and succeeded just before leaving MIT.

The analysis also revealed that the enzyme has two openings — one where the starting materials enter and another that allows the growing polymer chain to exit.

New framework

Drennan’s lab now plans to try to solve structures of the enzyme while it is bound to substrates and products, which should yield even more information critical to understanding how it works.

“This is the beginning of a new era of studying these systems where we now have this framework, and with every experiment we do, we’re going to be learning more,” Drennan says.
