Piezotronic Logic Gates Take the Strain
US scientists have developed the first examples of logic gates (NAND, NOR and XOR gates) that can be switched simply by bending the substrate.
Quantum Dot Monolayers
Materials scientists from the USA have made a thin layer of quantum dots on a photonic crystal surface, thereby creating a stable material with enhanced emission properties.
Bottom-Up Meets Top-Down for Simple Surface Stripes
A simple way to create very small patterns on a surface by using a mixture of top-down and bottom-up technology has been developed. Self-assembly is combined with evaporation to make highly ordered nanoscale structures.
MaterialsViews Interviews: Yanglong Hou
MaterialsViews interviews Yanglong Hou of Peking University on nanobiotechnology and magnetic nanoparticles.
Book Review: Nanotechnology for the Energy Challenge
Professor Sanjay Mathur of the University of Cologne reviews Nanotechnology for the Energy Challenge, a new text covering areas of energy research where nanomaterials could make a big difference.
Flick of Switch Controls Medicine: Nanoparticle Drug Delivery
A recent review gives an up-to-the-minute round-up of how mesoporous silica nanoparticles are used to deliver drugs into cells.
Porous silicon nanoneedles for barcodes and other applications
Researchers at the University of Texas have fabricated biodegradable, nanobarcodes of silicon. The porosity of the silicon structures enables their applications in bioengineering, energy storage, and drug delivery systems.
Focussed Nanopatterning
Scientists develop a simple way to organise nanoparticles on a surface without the need to first alter the surface.
Dimensionally Different: Complex Patterned Photoresists
Scientists in the USA have exploited all three dimensions of patterned photoresists, to make complex components using just one template.
