Alignment of Nanotubes within Nanocomposites Defines Strength
A rigorous study by British and Irish scientists demonstrates a clear relationship between alignment and loading of nanotubes in nanocomposites and the nanocomposite mechanical properties.
Nanomemory – Devices Based on Nanotubes and Nanowires
French scientists have made light-sensitive memory devices by combining carbon nanotubes and silicon nanowires.
Nanowelded Tubes are Superstrong
A team in Japan have made stronger than ever metal-carbon nanotubes junctions by nanowelding multiwalled carbon nanotubes to the contact surface.
Nanometer Precision in Nanotube Heterojunctions
Nanotubes whose properties alternate with nanometer precision can be made by a simple electrochemical process, show German scientists.
Nanoplasmonics – Teaching an Old Dog New Tricks
A recent concept article gives a round-up of how nanoplasmonic technology can be employed to control optical properties by use of appropriately shaped nanostructures.
Super-Sensitive SERS
By studying the thermal effects in SERS, scientists may be able to drastically alter the sensitivity of their system and provide vital information for the design of new SERS probes.
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.
