Tiny, perfectly smooth carbon spheres added to motor oil have been shown to reduce friction and wear typically seen in engines by as much as 25 percent, suggesting a similar enhancement in fuel economy.
Researchers have developed nanocarriers that site-selectively release medicines/drugs at the tumor site in human and mouse lungs. The scientists report that this approach led to a significant increase in the effectiveness of current cancer medicines in lung tumour tissue.
Biomedical engineers are fighting back by developing nanotechnology built directly into orthopedic implants using a battery-activated device to power an army of microscopic germ-killers. Even antibiotic-resistant bacteria such as MRSA are on the hit list.
Researchers have for the first time imaged the inner workings of experimental solid-state batteries as they charged and discharged while making detailed measurements of their electrochemical health. Their work has helped explain why the batteries rapidly lose performance and suggests a way for improving them.
The National Institute of Standards and Technology (NIST) has issued a new silver nanoparticle reference material to support researchers studying potential environmental, health and safety risks associated with the nanoparticles, which are being incorporated in a growing number of consumer and industrial products for their antimicrobial properties.
Scientists report the chemical solution (water-based) synthesis of high-quality epitaxial thin films of perovkskite free of defects at square-centimeter scales and compatible with standard microfabrication techniques. These films show a robust ferromagnetic moment and large magnetoresistance at room temperature.
