A class of ultrasmall fluorescent core-shell silica nanoparticles developed at Cornell is showing an unexpected ability to ...

Scientists have designed an artificial color-changing material that mimics chameleon skin, with luminogens (molecules that make crystals glow) organized into different core and shell hydrogel layers ...

(Nanowerk Spotlight) Semiconductor nanoparticles, also known as quantum dots (QDs), have been studied for their size-tunable electronic and optical properties for over 30 years. Applications have been ...

Nanoshells are a class of nanoparticles consisting of a dielectric core surrounded by a thin metallic shell, typically made of gold or silver. The core material is usually silica or a polymer, while ...

The study reports on the development of core–shell magnetic nanocomposites coated with bioactive glass for combined bone cancer therapy and regeneration of the injured bone area. The magnetic ...

Inductors are deceptively simple. However, a closer look reveals underlying complexity. How else can you explain the many types of core materials, types of windings, sizes, geometries and wide range ...
