The system, made with a shell of metamaterials which concentrates the magnetic field, could transmit energy efficiently enough to charge mobile devices without having to place them close to the charging base.
A nanoparticle commonly used in food, cosmetics, sunscreen and other products can have subtle effects on the activity of genes expressing enzymes that address oxidative stress inside two types of cells.
A simple and open access to high-class infrastructure for the reliable production of small batches of functionalized nanoparticles and nanocomposites for testing could ease the way towards new nano-based products for chemical and pharmaceutical companies.
A multi-institutional team of researchers has discovered novel magnetic behavior on the surface of a specialized material that holds promise for smaller, more efficient devices and other advanced technology.
Scientists have developed a new material that can temporarily protect and tighten skin, and smooth wrinkles. With further development, it could also be used to deliver drugs to help treat skin conditions such as eczema and other types of dermatitis.
This one-step method starts with engineered bacterial cells in a simple, aqueous solution and ends with functional semiconducting nanoparticles, all without resorting to high temperatures and toxic chemicals.
Researchers have described one of the cell's key enzymes, the calcium pump, in its decisive moment - a so-called transition state. These findings provide a very detailed picture of how one of the most energy-consuming processes in the body takes place.
