Researchers have demonstrated a new method for testing microscopic aeronautical materials at ultra-high temperatures. By combining electron microscopy and laser heating, scientists can evaluate these materials much more quickly and inexpensively than with traditional testing.
You can't see them, but most of the metals around you—coins, silverware, even the steel beams holding up buildings and overpasses—are made up of tiny metal grains. Under a powerful enough microscope, you can see interlocking crystals that look like a granite countertop.
Modern anticancer therapies aim to attack tumor cells while sparing healthy tissue. An interdisciplinary team of researchers at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and FU Berlin has made important progress in this area: the scientists have produced tiny nanoparticles that are designed to specifically target cancer cells. They can navigate directly to the tumor cells and visualize […]
A joint research team led by Prof. Huang Jiahui and Prof. Qiao Botao from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), as well as Prof. Sun Keju from Yanshan University, developed an anti-sintering gold nanocatalyst with high catalytic activity. The results were published in Nature Communications.
The electronics industry might look very different today were it not for the dramatic drop in cost of high-quality single-crystalline silicon wafers over the past five decades. So what would happen if the cost of single-crystalline graphene took a similarly significant plunge? Results reported in ACS Nano may bring this closer to reality, as they […]
Beating cancer and a plethora of other diseases does not only depend on getting hold of the right drugs—it's also about getting them to the right places in the body, while keeping damage to healthy tissues at a minimum. DNA nanostructures such as self-assembling DNA origami that fold into defined shapes are promising vehicles for […]
In a study published in Advanced Materials, researchers at Aalto University, the University of Tokyo, Sichuan University and the University of British Columbia have demonstrated that plant-derived cellulose nanocrystals (CNCs) can form an adhesive that fully integrates the concepts of sustainability, performance and cost, which are generally extremely challenging to achieve simultaneously.
Dr. Hun-Gi Jung and his research team at the Center for Energy Storage Research of the Korea Institute of Science and Technology (KIST, President Lee Byung Gwon) have announced the development of silicon anode materials that can increase battery capacity four-fold in comparison to graphite anode materials and enable rapid charging to more than 80% […]
Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department of Physics developed a thickness-controlled black phosphorous tunnel field-effect transistor (TFET) that shows 10-times lower switching power consumption as well as 10,000-times lower standby power consumption […]
