International Collaboration Boosts Nanotechnology Research
Despite their initial focus on national economic competitiveness, the nanotechnology research initiatives now funded by more than 60 countries have become increasingly collaborative, with...
Solar cells could reach 70 percent efficiency
It has long been thought that conversion efficiency of solar cells cannot exceed 34 percent for a single material or less than about 45...
Terahertz Invisibility Cloak Unveiled at Conference on Lasers and Electro-Optics 2011
Humans generally recognize objects through two features: their shape and color. To render an object invisible, one must be able to manipulate light so...
First practical nanogenerator could replace conventional batteries
After six years of intensive effort, scientists are reporting development of the first commercially viable nanogenerator, a flexible chip that can use body movements...
The World’s Smallest Battery
A benchtop version of the world’s smallest battery — its anode a single nanowire one seven-thousandth the thickness of a human hair — has...
Smart Windows – Block Heat On Hot Days But Let In The Heat In...
New materials science research could hasten the creation of "smart" windows that reflect heat from the sun on hot summer days but let in...
Nitrogen Dioxide Gas Sensor Based on Vertically-Grown In As Nanowires
Imec and Holst Centre have developed an innovative sensor for measuring ultra-low concentrations of NO2. These sensors are important for applications that monitor environmental...
The piezoelectric effect in graphene at nanoscale
By depositing atoms on one side of a grid of the “miracle material” graphene, researchers at Stanford have engineered piezoelectricity into a nanoscale material...
How Fuel Cells working on the nanoscale
For the first time, physical chemistry reactions in a fuel cell can now be observed and described in detail on the nanoscale.
This innovation is...
Nanotrees Harvest the Sun’s Energy to Turn Water into Hydrogen Fuel
University of California, San Diego electrical engineers are building a forest of tiny nanowire trees in order to cleanly capture solar energy without using...
