GREEN SHEEN  The green hairstreak butterfly’s color is due to a nanoscale surface on its wings that reflects light. Researchers have now re-created this structure in the lab.  ~~ ATOSF/ISTOCKPHOTO

Butterfly-inspired nanostructures can sort light

Scientists re-created a nanostructure found on butterflies that can separate out circularly polarized light, a characteristic that may be useful for telecommunications.

IBM's New Computer Chips Can Fit 30 Billion Transistors on Your Fingertip

IBM researchers have announced a brand new way of manufacturing computer chips, one that will see 30 billion transistors packed into a space the size of a fingernail, and give a serious boost to the processing power we need.

Nano 'hall of mirrors' causes molecules to mix with light

Nano 'hall of mirrors' causes molecules to mix with light

When a molecule emits a blink of light, it doesn't expect it to ever come back. However researchers have now managed to place single molecules in such a tiny optical cavity that emitted photons, or particles of light, return to the molecule before they have properly left. The energy oscillates back and forth between light and molecule, resulting in a complete mixing of the two.

DNA shaping up to be ideal framework for rationally designed nanostructures

DNA shaping up to be ideal framework for rationally designed nanostructures

A cube, an octahedron, a prism—these are among the polyhedral structures, or frames, made of DNA that scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed to connect nanoparticles into a variety of precisely structured three-dimensional (3D) lattices. The scientists also developed a method to integrate nanoparticles and DNA frames into interconnecting modules, expanding the diversity of possible structures.

Scientists Complete First Successful “Surgery” on a Nanoparticle.  Chemists conducted the first site-specific surgery on a nanoparticle, affording it 10 times more photoluminescence, a property useful in many applications. They hope to generalize this technique so that any nanoparticle property could be enhanced.

NANO VARIETY Nanoparticles can repair blood vessel damage, break up plaques, stop immune molecules from overreacting and even respond to the pressure of plaque-narrowed vessels in animal studies.  ~~ Nicolle Rager Fuller

Nanoparticles beat back atherosclerosis

Nanoparticles that find and destroy waxy plaques in blood vessels could be the next big treatment for heart disease.

Research alliance builds new transistor for 5nm technology

Research alliance builds new transistor for 5nm technology

IBM, its Research Alliance partners Globalfoundries and Samsung, and equipment suppliers have developed an industry-first process to build silicon nanosheet transistors that will enable 5 nanometer (nm) chips. The details of the process will be presented at the 2017 Symposia on VLSI Technology and Circuits conference in Kyoto, Japan. In less than two years since developing a 7nm test node chip with 20 billion transistors, scientists have paved the way for 30 billion switches on a…

Synthetic nanoparticles achieve the complexity of protein molecules

Synthetic nanoparticles achieve the complexity of protein molecules

Chemists at Carnegie Mellon University have demonstrated that synthetic nanoparticles can achieve the same level of structural complexity, hierarchy and accuracy as their natural counterparts - biomolecules. The study, published in Science, also reveals the atomic-level mechanisms behind nanoparticle self-assembly.
