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.
They report two of the magnetic transitions, with a distinctive transition above room temperature and look into its causes, opening doors to potential applications in realizing new spintronic devices.
Researchers predict that next-generation electronics will be component-free, non-rigid, bendable, flexible, and with the ability for simple integration into different objects.
A new study has shown that a magnetic uranium compound can exhibit powerful thermoelectric properties, thereby producing four times the transverse voltage from heat compared to the previous record in a cobalt-manganese-gallium compound.
Heavy elements known as the actinides are important materials for medicine, energy, and national defense. But even though the first actinides were discovered by scientists at Berkeley Lab more than 50 years ago, we still don't know much about their chemical properties because only small amounts of these highly radioactive elements (or isotopes) are produced every year; they're expensive; and their radioactivity makes them challenging to handle and store safely.
