Newly developed nanocomposite sensors are based on zinc and indium oxides, and their efficiency is maximized by green light illumination. The proposed device could be used to detect combustible, explosive, or poisonous substances in the atmosphere even at low concentrations.
Transitions occurring in nanoscale systems, such as a chemical reaction or the folding of a protein, are strongly affected by friction and thermal noise. Such transitions occur most frequently at intermediate friction, an effect known as Kramers turnover.
An international research team pioneered the development of a novel thin, organic film that supports a million more times read-write cycles and consumes 1,000 times less power than commercial flash memories.
A microscopic 'pen' that is able to write structures small enough to trap and harness light using a commercially available printing technique could be used for sensing, biotechnology, lasers, and studying the interaction between light and matter.
Researchers have developed 'intelligent' nanoparticles which heat up to a temperature high enough to kill cancerous cells - but which then self-regulate and lose heat before they get hot enough to harm healthy tissue.
