Scientists from Russia, Germany, and Venezuela investigated the evolution of the 2-D semiconductor GaSe exposed to air. They revealed that GaSe properties could be exploited in nanoelectronics when manufactured in a vacuum or inert atmosphere. This research opens up new prospects for the technological application of this promising 2-D material.
While football-related concussions have been top of mind in recent years, people have struggled to create technology to accurately measure them in real time. BYU mechanical engineering Ph.D. student Jake Merrell and a team of researchers across three BYU departments have developed and tested a nano composite smartfoam that can be placed inside a football helmet (and pads) to more accurately test the impact and power of hits.
Most efforts to control ice build-up on structures like wind turbines and solar cells involve creating a surface that repels water. But Norwegian researchers have engineered a different approach that allows ice to form on a surface, but then causes it to crack off.
The materiality exhibited by manmade polymers currently relies on simple chemical bonds and the sequence order taken by molecules in the polymer chain. We now no longer need to rely on fate to determine such materiality with this new technique for precisely defining polymer-chain order. This system uses highly specific 'grabber' ends on each molecule that bond with only one type of 'pin' end on another molecule.
A new imaging technique makes it possible to precisely digitize clear objects and their surroundings, an achievement that has eluded current state-of-the-art 3-D rendering methods.
Where do cosmic rays come from? Solving a 50-year-old mystery, a collaboration of researchers has discovered it's much farther than the Milky Way.
A potent and long-lasting gene immunotherapy approach prevents and reverses symptoms of multiple sclerosis in mice, according to a study published Sept. 21 in the journal Molecular Therapy. The researchers used a viral vector to deliver a gene encoding a myelin sheath protein to the liver, thereby inducing robust and durable immune tolerance in mice by preventing T cells from attacking the myelin sheath.
A new, publicly available test to assess the safety of cell therapy products altered by lentivirus generates results within a few hours, potentially hastening the pace at which viral immunotherapies move into clinical trial. Current assays required by the US Food and Drug Administration take about six weeks to complete. The rapid test, which does not have a significant risk of false positives, is also a fraction of the cost of the standard approach.
IBS scientists visualize unstained chains of atoms, called polymers, moving inside tiny graphene pockets under electron microscopes.
The scientists from the Center for Applied Probabilistic Analysis of the Institute of Applied Mathematics and Telecommunications of the RUDN University have used a new mathematical model to find out why telecommunication systems and electronic equipment that handles numerous client requests break down. The results of the study were published in the Applied Mathematics and Computation journal.
