A new, low-cost cubesat mission led by the Johns Hopkins Applied Physics Laboratory will demonstrate technology needed to measure the absolute imbalance in the Earth's radiation budget for the first time, giving scientists valuable information to study our climate.
There are examples of art imitating nature all around us - the human conception of natural phenomena dazzles but does not often surprise. Yet when a researcher peered under the electron microscope last fall, she discovered the exact opposite. Instead of art imitating nature, she found nature imitating art.
A new study evaluates the impact of polyvinylpyrrolidone coated silver nanoparticles on the composting of municipal solid waste. The findings suggest that at relatively low concentrations, the organically rich waste management systems' functionality may not be influenced by the presence of silver nanoparticles.
ASTM E2864, Test Method for Measurement of Airborne Metal and Metal Oxide Nanoparticle Surface Area Concentration in Inhalation Exposure Chambers Using Krypton Gas Adsorption, was developed by Subcommittee E56.02 on Physical and Chemical Characterization, part of ASTM International Committee E56 on Nanotechnology.
Originally predicted in the 1920s by Satyendranath Bose and Albert Einstein, applications could include energy-efficient lasers and optical switches, critical components for future computer systems processing Big Data.
By relentlessly miniaturizing a pre-World War II computer technology, and combining this with a new and durable material, researchers at Case Western Reserve University have built nanoscale switches and logic gates that operate more energy-efficiently than those now used by the billions in computers, tablets and smart phones.
