Scientists find that holes can also improve technology, including medical devices. The article describes an entirely new way to make a solar cell: by etching holes in the top layer to make it porous.

Holes help make sponges and English muffins useful (and, in the case of the latter, delicious). Without holes, they wouldn’t be flexible enough to bend into small crevices, or to sop up the perfect amount of jam and butter.

In a new study, University of Chicago scientists find that holes can also improve technology, including medical devices. Published in Nature Materials, the paper describes an entirely new way to make a solar cell: by etching holes in the top layer to make it porous. The innovation could form the basis for a less-invasive pacemaker, or similar medical devices. It could be paired with a small light source to reduce the size of the bulky batteries that are currently implanted along with today’s pacemakers.

“We hope this opens many possibilities for further improvements in this field,” said Aleksander Prominski, the first author on the paper.

Prominski is a member of the lab of University of Chicago chemist Bozhi Tian, which specializes in creating ways to connect biological tissue and artificial materials – such as wires to modulate brain signals and surfaces for medical implants.

Wax worm saliva contains enzymes capable of breaking down plastics

A team of CSIC researchers has discovered that wax worm saliva degrades plastic; a discovery with numerous applications for treating or recycling plastic waste. Back in 2017, the team discovered that this worm species (the lepidopteran Galleria mellonella) is able to break down plastic (polyethylene), and now they have discovered just how it does this: its saliva contains enzymes (pertaining to the phenol oxidase family) that can rapidly set off polyethylene degradation at room temperature. These enzymes are the first and only known enzymes capable of degrading polyethylene plastic without requiring pre-treatment, according to Federica Bertocchini, a CSIC researcher at the CIB-CSIC (Centre for Biological Research) who led the study. The results of the work, pending review, have been published in preprint in the BioRxiv online archive.

“For plastic to degrade, oxygen must penetrate the polymer (the plastic molecule). This is the first step in oxidation, which is usually a result of exposure to sunlight or high temperatures, and represents a bottleneck that slows down the degradation of plastics like polyethylene, one of the most resistant polymers,” explains Bertocchini. “That is why, under normal environmental conditions, plastic takes months or even years to degrade,” she adds.

“Now we have found out that enzymes in the wax worm’s saliva perform this crucial step: they oxidize the plastic. This means they can overcome the bottleneck in the plastic degradation process and accelerate its decomposition,” she adds.

A good defect? Researchers discover helicoidal screw dislocations in layered polymers

Dr. Edwin L. Thomas, professor in the Department of Materials Science and Engineering, and a team of researchers from Texas A&M University and Yonsei University have recently discovered a helicoidal-shaped defect in layered polymers, uncovering how solvents can diffuse through layers and produce color changes.

This research was recently published in Science Advances.

In some human-interactive electronics, such as temperature gauges or health sensors, polymers are used that are capable of changing color depending on stimuli. This phenomenon is referred to as stimuli-interactive structural colors because the material reacts and changes color due to environmental changes, such as a solvent or solution.

A material that has a one-dimensional periodic structure comprised of two (A and B) layers acts like a photonic crystal and can reflect light of a given wavelength (color) depending on the thickness of each layer. Stimuli-interactive structural color works by altering photonic crystals using external stimuli or forces. The thickness of each polymer layer affects the color of the light reflected: If all the layers in a material are of the same thickness, a single color will be reflected. If different parts of the material are composed of stacks of layers, each having a different thickness, each layer will reflect a different color and the material will appear like a normal metal material, reflecting all colors.

New technology dramatically increases the recovery rate of precious metals from waste

In South Korea, which relies on imports for 99.3% of its metal resources, the per capita consumption of those metal resources is the highest in the Organization for Economic Co-operation and Development, and consumption of precious metals in industries such as renewable energy, healthcare and semiconductors is increasing. Gold is in demand for applications such as batteries, electric vehicles and renewable energy in the electric and electronic industries, but is a big variable in the industry due to its limited availability and high cost. Thus, research on urban mining, which extracts precious metals from waste, is being actively conducted around the world. However, most of the technologies for extracting high-purity gold from waste resources require large amounts of chemicals and high operating temperatures; therefore, it has regulatory and efficiency problems.

A Korean research team has developed a technology that can dramatically increase the recovery rate of precious metals from waste. The research team, comprising Dr. Jae Woo Choi and Dr. Kyung-Won Jung from the Center for Water Cycle Research at the Korea Institute of Science and Technology (KIST), reported that they developed a gold recovery process with the world’s highest recovery efficiency of 99.9 %. The technology is a capsule-type material in which a polymeric shell surrounds a multi-layered internal structure.

Cell Mates

Architects often wander through their buildings, examining details up close – gaining a different perspective to a flat drawing or table-top model. Here cell biologists use virtual reality to step inside a cell – strolling past structures they might normally only see twinkling under a microscope, reaching out every now and then to label them in different colours. Looking a little like a child’s climbing frame, this is a reconstruction of a network of intermediate filaments – rigid molecules of keratin that prop up the cell like girders in a skyscraper. The scientist’s models – based on microscopy scans – also give them a sort of virtual skeleton on which to hang future mechanobiological details. Next maybe: the neighbouring network of stretchy actin molecules that uproot this tiny architecture so cells can wander through their environment during development or diseases like cancer.
