An artificial intelligence technique — machine learning — is helping accelerate the development of highly tunable materials known as metal-organic frameworks (MOFs) that have important applications in chemical separations, adsorption, catalysis, and sensing.
The performance of flexible large-area organic photodiodes has advanced to the point that they can now offer advantages over conventional silicon photodiode technology, particularly for applications such as biomedical imaging and biometric monitoring that require detecting low levels of light across large areas.
Using large-scale computer simulations, researchers have mapped out the surprising behavior and mechanics of complex particle-solvent microgel systems, learning how the “soft and squishy” particles deform, swell, de-swell, and penetrate each other as they respond to compression.
Non-pharmaceutical interventions such as voluntary shelter-in-place, quarantines, and other steps taken to control the SARS-CoV-2 virus can reduce the peak number of infections, daily infection rates, cumulative infections, and overall deaths, a new study published in the journal PLOS ONE has found.
Using a device that could be built with a dollar’s worth of open-source parts and a 3D-printed case, researchers want to help the hundreds of millions of older people worldwide who can’t afford existing hearing aids to address their age-related hearing loss.
By varying the energy and dose of tightly-focused electron beams, researchers have demonstrated the ability to both etch away and deposit high-resolution nanoscale patterns on two-dimensional layers of graphene oxide. The 3D additive/subtractive “sculpting” can be done without changing the chemistry of the electron beam deposition chamber, providing the foundation for building a new generation of nanoscale structures.
A new low-temperature multi-phase process for upgrading lignin bio-oil to hydrocarbons could help expand use of the lignin, which is now largely a waste product left over from the productions of cellulose and bioethanol from trees and other woody plants.
Imagine a reusable face mask that protects wearers and those around them from SARS-CoV-2, is comfortable enough to wear all day, and stays in place without frequent adjustment. Based on decades of experience with filtration and textile materials, Georgia Institute of Technology researchers have designed a new mask intended to do just that — and are providing the plans so individuals and manufacturers can make it.
Emergency medical technicians (EMTs), military medics, and emergency room physicians could one day be better able to treat victims of vehicular accidents, gunshot wounds, and battlefield injuries thanks to a new device under development that may more accurately assess the effects of blood loss due to hemorrhage.
Researchers at the Georgia Institute of Technology and University of Missouri developed a new microgel drug delivery method that could extend the effectiveness of pancreatic islet transplantations — from several years to possibly the entire lifespan of a recipient.
Reduced resilience of plant biomes in North America could be setting the stage for the kind of mass extinctions not seen since the retreat of glaciers and arrival of humans about 13,000 years ago, cautions a new study published August 20 in the journal Global Change Biology.
Running into an unseen spiderweb in the woods can be scary enough, but what if you had to worry about a spiderweb – and the spider – being catapulted at you? That’s what happens to insects in the Amazon rain forests of Peru, where a tiny slingshot spider launches a web – and itself – to catch unsuspecting flies and mosquitoes.
Portable disinfection chambers that use ultraviolet (UV) light to inactivate virus particles could allow emergency medical technicians, police officers, healthcare workers, pharmacy technicians, and others to quickly disinfect their personal protective equipment (PPE) as they need it.
New research by the Georgia Institute of Technology and Northwestern Engineering expands the understanding of origami structures, opening possibilities for mechanical metamaterials to be used in soft robotics and medical devices.
New membrane technology developed by a team of researchers from the Georgia Institute of Technology, Imperial College London, and ExxonMobil could help reduce carbon emissions and energy intensity associated with refining crude oil. Laboratory testing suggests that this polymer membrane technology could replace some conventional heat-based distillation processes in the future.
A new study shows that ozone gas, a highly reactive chemical composed of three oxygen atoms, could provide a safe means for disinfecting certain types of personal protective equipment that are in high demand for shielding health care personnel from Covid-19.
For the next several months, visitors to the Atlanta Botanical Garden will be able to observe the testing of a new high-tech tool in the battle to save some of the world’s most endangered species. SlothBot, a slow-moving and energy-efficient robot that can linger in the trees to monitor animals, plants, and the environment below, will be tested near the Garden’s popular Canopy Walk.
Notice how hand sanitizer has made a comeback? It was running out, but this charitable initiative helped revive it by tapping into ethyl alcohol and FDA approval.
