New criteria to determine whether shear bands are beneficial or harmful to crystalline materials
Shear band formation is not typically a good sign in a material—the bands often appear before a material fractures or fails. But materials science and engineering researchers at the University of Wisconsin–Madison have found that shear bands aren.....»»

Low-cost flexible metasurfaces to increase the efficiency of optoelectronic devices
Metasurfaces are two-dimensional counterparts of metamaterials, which are artificial materials that possess unusual characteristics. With a variety of fascinatingly innovative and diverse uses, these specially-prepared surfaces with engineered patter.....»»
World"s first micromachine twists 2D materials at will
Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" of 1.1 degrees—dubbe.....»»
Repurposing pencil lead as an optical material using plasma
Optical materials are essential in many modern applications, but controlling the way a material reflects light on its surface is costly and difficult. Now, in a recent study, researchers from Japan found a simple and low-cost way of tuning the reflec.....»»

Calls to ban "harmful pornography" are rife—here"s what teens actually think about porn
Pornography has been in the news a lot this year. It was at the center of discussions addressing violence against women back in May. Deepfake pornography has also been in the headlines......»»
Quality control: Neatly arranging crystal growth to make fine thin films
Table salt and refined sugar look white to our eyes, but that is only because their individual colorless crystals scatter visible light. This feature of crystals is not always desirable when it comes to materials for optical and electrical devices, h.....»»
Study discovers an electric current in the gut that attracts pathogens like Salmonella
How do bad bacteria find entry points in the body to cause infection? This question is fundamental for infectious disease experts and people who study bacteria. Harmful pathogens, like Salmonella, find their way through a complex gut system where the.....»»
Advanced materials could provide more durable metals for fusion power reactors
For many decades, nuclear fusion power has been viewed as the ultimate energy source. A fusion power plant could generate carbon-free energy at a scale needed to address climate change. And it could be fueled by deuterium recovered from an essentiall.....»»
Neutrons illuminate environmental and biological mysteries
Neutron techniques have long been valued in various scientific fields for their ability to penetrate materials without altering their structure. However, their use in environmental and biological sciences has been limited. Complex systems like soil-w.....»»
New supramolecular polymer shows spontaneous unfolding and aggregation
In polymers, the competition between the folding and aggregation of chains, both at an individual level and between chains, can determine the mechanical, thermal, and conductive properties of such materials. Understanding the interplay of folding and.....»»
Researchers develop nanoparticle array implantation for sensitive and reusable detection
Shanghai Jiao Tong University (SJTU) researchers have developed a highly sensitive and reusable surface-enhanced Raman spectroscopy (SERS) microfluidics system that has achieved a detection limit lower than 10 ppt (parts per trillion) of harmful subs.....»»
Specialized materials could passively control the internal temperature of space habitats
Areas of space have wildly different temperatures depending on whether they are directly in sunlight or not. For example, temperatures on the moon can range from 121 °C during the lunar "day" (which lasts for two weeks), then drop down to -133 °C a.....»»
Researchers shed light on how to make photopolymerization much more efficient
Polymers are materials made out of long, repeating chains of molecules, and it is the interaction between these chains that dictates most of a polymer's physicochemical properties. In accordance with this intuitive understanding of polymers, which da.....»»
Morphable materials: Researchers coax nanoparticles to reconfigure themselves
A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible with an approach that combines an electron microscope, a small sample holder with microscopic channels, and computer simulations, a.....»»
