Scientists have been systematically studying the effects of transition metal oxide nanoparticles on human lung cells. These nanoparticles are used extensively in optical and recording devices, water purification systems, cosmetics and skin care products, and targeted drug delivery, among other applications.
Researchers are proposing a new technology that might control the flow of heat the way electronic devices control electrical current, an advance that could have applications in a diverse range of fields from electronics to textiles.
University of Houston researchers have developed a new stretchable and transparent electrical conductor, bringing the potential for a fully foldable cell phone or a flat-screen television that can be folded and carried under your arm closer to reality.
Da die anhaltende Miniaturisierung elektronischer Bauelemente bald an ihre physikalischen Grenzen stößt, suchen Forscher nach neuen Herstellungsmethoden. Einen aussichtsreichen Ansatz liefert DNA-Origami, bei dem sich Einzelstränge des Biomoleküls selbstständig zu beliebig geformten Nanostrukturen zusammenfinden.
Japan's National Institute for Materials Science (NIMS) and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have signed a 5-year collaborative agreement to co-publish the open access journal Science and Technology of Advanced Materials (STAM). Their goal is to make STAM one of the world's leading publications in materials science.
Nearly 30 years after the discovery of high-temperature superconductivity, many questions remain, but an Oak Ridge National Laboratory team is providing insight that could lead to better superconductors.
A team of researchers at the University of Toronto has discovered a method of assembling "building blocks" of gold nanoparticles as the vehicle to deliver cancer medications or cancer-identifying markers directly into cancerous tumors.
An interdisciplinary team of scientists and engineers from The MITRE Corporation and Harvard University have taken key steps toward ultra-small electronic computer systems that push beyond the imminent end of Moore's Law, which states that the device density and overall processing power for computers will double every two to three years.
Silk and diamonds aren't just for ties and jewelry anymore. They're ingredients for a new kind of tiny glowing particle that could provide doctors and researchers with a novel technique for biological imaging and drug delivery.
The sponges of the future will do more than clean house. Delivering drugs and trapping gases are all potential applications. That's what chemist Jason Benedict had in mind when he led the design of a new, porous material whose pores change shape in response to ultraviolet light.
A new type of electrical generator uses bacterial spores to harness the untapped power of evaporating water, according to research conducted at the Wyss Institute of Biologically Inspired Engineering at Harvard University. Its developers foresee electrical generators driven by changes in humidity from sun-warmed ponds and harbors.
For the first time ever, scientists have managed to move single atoms vertically inside a crystal. This is important for the further development of nanostructures. Simultaneously, the physicists found a method for measuring a transistor-like behaviour of single atoms.
