To understand the process, behaviors of lithium ion,

A keen sense of smell is a powerful ability shared by many organisms. However, it has proven difficult to replicate by artificial means. Researchers combined biological and engineered elements to create what is known as a biohybrid component. Their volatile organic compound sensor can effectively detect odors in gaseous form. They hope to refine the

Scientists tame photon-magnon interaction. Working with theorists in the University of Chicago’s Pritzker School of Molecular Engineering, researchers in the U.S. Department of Energy’s (DOE) Argonne National Laboratory have achieved a scientific control that is a first of its kind. They demonstrated a novel approach that allows real-time control of the interactions between microwave photons

A proton exchange membrane fuel cell is a chemical cell that converts energy released when a substance reacts into electrical energy with zero emission. It is an excellent substitute for fossil fuel. However, low activity and stability of the Pt-based catalysts in the oxygen reduction reaction (ORR) of the battery cathode restricted the output power

Irvine, Calif., Jan. 11, 2021 – Often admired for their flawless appearance to the naked eye, crystals can have defects at the nanometer scale, and these imperfections may affect the thermal and heat transport properties of crystalline materials used in a variety of high-technology devices. Employing newly developed electron microscopy techniques, researchers at the University

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed insulin nanoparticles that may one day become the basis for an oral medicine, and an alternative to insulin injections for diabetic patients. In a pre-clinical study, the NTU Singapore team fed insulin-containing nanoparticles to rats and found that insulin increased in their blood minutes later.

COLUMBUS, Ohio – An unfortunate truth about the use of mechanical ventilation to save the lives of patients in respiratory distress is that the pressure used to inflate the lungs is likely to cause further lung damage. In a new study, scientists identified a molecule that is produced by immune cells during mechanical ventilation to
