A new study by researchers from the Georgia Institute of Technology has found that wearing a face mask can safeguard a person and others from Covid-19, but the kind of material and how many fabric layers are utilized can considerably influence the risk of exposure.
In perovskite solar cells (PSCs), grain boundaries (GBs) have been identified to be detrimental to the photovoltaic performance of the devices.
University of Rochester researchers who demonstrated superconducting materials at room temperatures last fall, now report a new technique in the quest to also create the materials at lower pressures.
Scientists from the Skoltech Center for Energy Science and Technology (CEST) have developed a method for modeling the behavior of 2D materials under pressure. The research will help create pressure sensors based on silicene or other 2D materials. The paper was published in the ACS Nano journal.
Nature's strongest material now has some stiff competition. For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than the common cubic diamonds found in nature and often used in jewelry.
Superalloys that withstand extremely high temperatures could soon be tuned even more finely for specific properties such as mechanical strength, as a result of new findings published today.
Skyrmions - tiny magnetic vortices - are considered promising candidates for tomorrow's information memory devices which may be able to achieve enormous data storage and processing capacities. A research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has developed a method to grow a particular magnetic thin-film material that hosts these magnetic vortices.
On sultry summer afternoons, heating, ventilation and air conditioning (HVAC) systems provide much-needed relief from the harsh heat and humidity. These systems, which often come with dehumidifiers, are currently not energy efficient, guzzling around 76% of the electricity in commercial and residential buildings.
At the University of Illinois Chicago (UIC), scientists have designed a reactive electrochemical membrane with the ability to adsorb toxins and degrade them. The team is currently testing the technology in the field.
Scientists have been studying particulate photocatalysts as an easy and economical solution to split water into oxygen and hydrogen for the large-scale production of hydrogen through the use of solar energy.
