The International Center for Technology Assessment (ICTA) welcomes the findings of a new report by an expert panel yesterday, which concluded that despite the surge of nanomaterials in the marketplace, not enough is known about their potential health and environmental risks.
The biggest challenge with hydrogen-powered fuel cells lies in the storage of hydrogen: how to store enough of it, in a safe and cost-effective manner, to power a vehicle for 300 miles? Lawrence Berkeley National Laboratory (Berkeley Lab) is aiming to solve this problem by synthesizing novel materials with high hydrogen adsorption capacities.
After celebrating its 10th anniversary last year, nano tech 2012 - The11th International Nanotechnology Exhibition and Conference will take place from February 15 to February 17, 2012 at the International Exhibition Center Tokyo Big Sight in Japan
A quantum computer based on quantum particles instead of classical bits, can in principle outperform any classical computer. However, it still remains an open question, how fast and how efficient quantum computers really may be able to work. A critical limitation will be given by the velocity with which a quantum signal can spread within a processing unit. For the first time, a group of physicists has succeeded in observing such a process in a solid-state like system.
Tiny components with the ability to emit single particles of light are important for various technological innovations. Physicists now have made significant progress in the fabrication of such structures.
Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality. Whilst previous studies have either been theoretical in nature or limited to the cloaking of two-dimensional objects, this study shows how ordinary objects can be cloaked in their natural environment in all directions and from all of an observer's positions.
Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life.
It's official: The world's fastest movie was shot by DESY's X-ray laser FLASH in Hamburg. In its 2012 edition, the famous Guinness Book of World Records lists an interval of a mere 50 femtoseconds between two frames for FLASH.
Foldit, which was initially funded by DARPA, is a game with an online community of 240,000 players that allows non-experts and experts alike to collaborate and solve protein folding puzzles. Solutions to these puzzles are sent to biochemistry researchers to analyze for advances in protein design prediction.
Despite extensive investment in nanotechnology and increasing commercialization over the last decade, insufficient understanding remains about the environmental, health, and safety aspects of nanomaterials. Without a coordinated research plan to help guide efforts to manage and avoid potential risks, the future of safe and sustainable nanotechnology is uncertain, says a new report from the National Research Council.
The planet Jupiter keeps asteroids on stable orbits - and in a similar way, electrons can be stabilized in their orbit around the atomic nucleus. Calculations carried out at the Vienna University of Technology have now been verified in an experiment.
