3D printed cubes,with intricate fractal voids efficiently dissipate shockwaves, potentially leading to new types of lightweight armor and materials to better withstand explosions and impacts.
The air around us is still getting more and more polluted. No wonder many scientists strive to find a way to purify it. Thanks to the work of an international team led by prof. Juan Carlos Colmenares from the Institute of Physical Chemistry, Polish Academy of Sciences, we are a big step closer to achieve this goal. They found a way to make an efficient reactive adsorbent able to purify the air from various toxic compounds, cheaply, and effectively.
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range - and they are unrivalled in terms of weight.
Universitat Rovira i Virgili researchers have developed a nanometric-scale theoretical model to create structures that kill bacteria by using elastic forces. The results of this study pave the way to creating new antibacterial materials.
Researchers developed biomaterial-based inks that respond to and quantify chemicals released from the body or in the environment by changing color. Multiple inks can be screen printed onto clothes or even face masks at high resolution, providing a detailed map of human response or exposure
The United States Army Research Laboratory is lending support to a Texas A&M University research project investigating potential improvement of ballistic performance of armor materials. The project, led by Dr. Justin Wilkerson, assistant professor and James J. Cain '51 Faculty Fellow II in the J. Mike Walker '66 Department of Mechanical Engineering, focuses on identifying what damaging effects could be caused by particular flaws -- known as vacancies -- in the atomic structure of aluminum.
Researchers compared the risk of suicide by firearm based on sociodemographic characteristics of US adults.
Japanese researchers have succeeded in catalytic asymmetric iodoesterification from simple alkene substrates and carboxylic acids. Published in Angewandte Chemie International Edition on April 27, this new research, was accomplished by precisely controlling multiple interactions in a single catalytic reaction. This synthetic reaction is expected to contribute to the simplification of industrial processes and greater efficiency in optical active drug production.
new study conducted in seven Front Range emergency departments demonstrated success in helping parents make their homes safer when a teen is distressed.
Demand is growing for new materials that can be printed at ever smaller dimensions. But materials that work well on Earth don't always hold up well at high altitudes and in space. Scientists are now creating metal-based nanomaterials for circuit boards that could be resistant to high-altitude radiation encountered by aerospace equipment and fighter jets. The researchers are presenting their results through the American Chemical Society SciMeetings online platform.
