Atomically thin minerals show promise as proton conducting membranes for green technologies

Researchers at The University of Manchester discovered that atomically- thin micas—the name given to a type of common mineral found in soil—are excellent proton conductors. This surprising result is important for the use of 2-D materials in applications such as fuel cells and other hydrogen-related technologies.

Previously, the Manchester researchers led by Professor Andre Geim and Dr. Marcelo Lozada-Hidalgo found that one-atom thick materials like graphene are highly permeable to protons, nuclei of hydrogen atoms. However, they also found that other 2-D materials such as molybdenum sulphide (MoS2), that were just three atoms thick, were completely impermeable to protons. These results suggested that only one-atom thick crystals could be permeable to protons.

Writing in Nature Nanotechnology, the team have shown that protons can easily permeate through few-layered micas despite the fact that they are 10 times thicker than graphene. Micas, like graphite, consist of crystal layers stacked on top of each other and can be sliced down to a single layer. The team isolated one of these layers and found that it was 100 times more permeable to protons than graphene.

This Day in Aviation History

March 2nd, 1969

First flight of the Concorde.

Aérospatiale/BAC Concorde /ˈkɒŋkɔːrd/ is a turbojet-powered supersonic passenger jet that was operated until 2003. It had a maximum speed over twice the speed of sound at Mach 2.04 (1,354 mph or 2,180 km/h at cruise altitude), with seating for 92 to 128 passengers. First flown in 1969, Concorde entered service in 1976 and continued flying for the next 27 years. It is one of only two supersonic transports to have been operated commercially; the other is the Soviet-built Tupolev Tu-144, which ran for a much shorter period of time before it was grounded and retired due to safety and budget issues.

Concorde was jointly developed and manufactured by Aérospatiale and the British Aircraft Corporation (BAC) under an Anglo-French treaty. Concorde’s name, meaning harmony or union, reflects the cooperation on the project between the United Kingdom and France. In the UK, any or all of the type are known simply as “Concorde”, without an article. Twenty aircraft were built including six prototypes and development aircraft. Air France (AF) and British Airways (BA) each received seven aircraft. The research and development failed to make a profit and the two airlines bought the aircraft at a huge discount…..

Biophotonics: In situ printing liquid superlenses to image butterfly wings and nanobiostructures

Nanostructures and natural patterns have long fascinated researchers in bioinspired materials engineering. Biological samples can be imaged and observed at the nanoscale using sophisticated analytical tools in materials science, including scanning electron microscopy (SEM) and transmission electron microscopy (TEM). While imaging methods contribute to the understanding of structures by revealing material properties for biomimetic materials synthesis, they have often done so with the loss of photonic properties inherent to the materials.

In a new method, materials scientists Boliang Jia and colleagues at the departments of mechanical engineering and robotics presented a printable biocompatible superlens placed directly on objects of interest to observe subdiffraction-limited features (resolution beyond the diffraction limit). They then viewed the natural features using an optical microscope to demonstrate nanoscale imaging of butterfly wings in color. The study allowed super-resolution imaging and a larger field of view (FOV) compared to the previous dielectric microsphere-based optical systems of super-resolution microscopy.

The new approach created a fast and flexible path to observe the direct colors of biological features at the nanoscale in the visible range. The results are now published in Microsystems and Nanoengineering, where the work allowed optical measurements at the subdiffraction-limited scale. A superlens is based on an optical material with a negative index of refraction (optical metamaterials) that could experimentally reverse nearly all known optical phenomena. Technically, a thin negative-index film can function as a ‘superlens’ to provide image detail with a resolution beyond the diffraction limit to which all positive-index lenses are subjected to.

Ask Ethan: How Can LISA, Without Fixed-Length Arms, Ever Detect Gravitational Waves?

“LIGO works by having these exquisitely precise lasers, reflected down perfectly length-calibrated paths, to detect these tiny changes in distance (less than the width of a proton) induced by a passing gravitational wave. With LISA, we plan on having three independent, untethered spacecrafts freely-floating in space. They’ll be affected by all sorts of phenomena, from gravity to radiation to the solar wind. How can we possibly get a gravitational wave signal out of this?”

Imagine you’ve got three spacecrafts, separated by 5 million kilometers apiece, orbiting in empty space behind the Earth. They’re affected by gravity, the pressure from solar radiation, the solar wind, cosmic rays, and literally everything that passes through their environment. Here on Earth, gravitational wave detectors, and the laser arms that allow us to build them, are kept at a fixed length, with gravitational waves causing those arms to expand and contract. In space, there is nothing to “fix” these distances.

So how will LISA ever possibly do this? How will it see a signal against the tremendous backdrop of noise? Find out on this edition of Ask Ethan!

Ask Ethan: Do Merging Black Holes Create An Information-Loss Paradox?

“When black holes merge they [lose] energy through gravitational waves. Does this pose the same problem as Hawking radiation does, with respect to loss of information? Or is the information on what has gone into the black hole somehow encoded into the gravitational wave? And if it is could we someday hope to decode what went into the black hole using gravitational waves?”

Black holes and entropy have long been a problem. If you calculate a black hole’s temperature and entropy in General Relativity alone, you get an absurd answer: 0. That implies that the pre-existing object that forms a black hole, which definitely has entropy, would see it disappear when it formed a black hole. But the entropy of a system can never decrease, implying that black holes must have an entropy after all: encoded on the surface of the event horizon. So let’s take two black holes with entropy on their event horizon and merge them together. What happens? You form a larger black hole with a larger event horizon, while gravitational waves carry away roughly 5% of that mass in the form of gravitational waves.

Who gets the entropy? Is it still conserved? And where does it go, in theory and in practice? Here’s what we know so far, for the final Ask Ethan of 2018!

Ferrofluid: You’ve heard of the Blackest Black, now get ready for the Magnet-iest Black!

A Ferrofluid (portmanteau of ferromagnetic and fluid) is a liquid that becomes strongly magnetized in the presence of a magnetic field. A grinding process for ferrofluid was invented in 1963 by NASA’s Steve Papell as a liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field. Which is really genius when you think about it.

Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). Each tiny particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields.

The magnetic attraction of nanoparticles is weak enough that the surfactant’s Van der Waals force is sufficient to prevent magnetic clumping or agglomeration. Ferrofluids usually do not retain magnetization in the absence of an externally applied field and thus are often classified as “superparamagnets” rather than ferromagnets.
