Among tumor characteristic cell types, cancer stem cells

One of

Metallic alloys at nanometer scale (nanoalloys) have great potentials in electrocatalysis. The interaction among different components in nanoalloys may modify the electronic configurations of active metals and generate synergistic effects, boosting their performance in terms of activity, durability and selectivity in electrocatalytic reactions. Alloying with cheap transition metals is an effective way to reduce the

Irvine, Calif. – University of California, Irvine materials science researchers are learning about resilience from the mantis shrimp. The ancient crustaceans are armed with two hammerlike raptorial appendages called dactyl clubs that they use to bludgeon and smash their prey. These fists, able to accelerate from the body at over 50 mph, deliver powerful blows

The devastating respiratory virus, influenza A virus, utilize its hemagglutinin (HA)

WASHINGTON, Aug. 17, 2020 — Global economic growth comes with increasing demand for energy, but stepping up energy production can be challenging. Recently, scientists have achieved record efficiency for solar-to-fuel conversion, and now they want to incorporate the machinery of photosynthesis to push it further. The researchers will present their results today at the American

The discovery, published in Nature Materials, may lead to applications in quantum information processing because time crystals automatically remain intact – coherent –

WASHINGTON, Aug. 17, 2020 — Oral bacteria are ready to spring into action the moment a dental hygienist finishes scraping plaque off a patient’s teeth. Eating sugar or other carbohydrates causes the bacteria to quickly rebuild this tough and sticky biofilm and to produce acids that corrode tooth enamel, leading to cavities. Scientists now report

Supported bimetallic catalysts are an important class of catalysts in heterogeneous catalysis. They can be applied in various fields, such as electrocatalysis, biomass conversion, and hydrogen production. However, traditional impregnation and immobilization methods for synthesizing supported bimetallic nanoparticles (BNPs) are often uncontrollable, thus creating BNPs with non-uniform particle size, low alloy degree and inhomogeneous distribution

A team of scientists led by Kenichiro Itami, Professor and Director of the Institute of Transformative Bio-Molecules (WPI-ITbM), has developed a new method for the synthesis of three-dimensional nanocarbons with the potential to advance materials science. Three-dimensional nanocarbons, next-generation materials with superior physical characteristics which are expected to find uses in fuel cells and organic
