Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery - and then recharge the phone in the blink of an eye.
Researchers from Rice University, DuPont Central Research and Development and Stanford University have announced a full-scale field test of an innovative process that gently but quickly destroys some of the world's most pervasive and problematic pollutants. The technology, called PGClear, originated from basic scientific research at Rice during a 10-year, federally funded initiative to use nanotechnology to clean the environment.
Inspired by plant components that respond to external stimuli, material scientists from ETH Zurich have devised a new method for producing composite materials from a variety of materials that adopt a pre-programmed shape autonomously.
Applying femtosecond x-ray methods, researchers at the Max-Born-Institute in Berlin (Germany) and the Ecole Polytechnique Federale de Lausanne (Switzerland) observed an extremely fast, collective electron transfer of ~100 molecular ions after excitation of a single electron in a crystal of transition metal complexes.
CIC nanoGUNE launches a new service called Simune with the aim of supporting a large variety of companies and institutions in their R+D processes. This service will perform computer simulations in order to study the behavior of matter at the atomic scale. In this way, Simune will help to solve specific technological problems with a lower investment.
Researchers are developing a new type of semiconductor technology for future computers and electronics based on two-dimensional nanocrystals layered in sheets less than a nanometer thick that could replace today's transistors.
Substanzen, die sich in winzigsten Poren befinden, weisen möglicherweise andere physikalische Eigenschaften auf als außerhalb der Poren. So gefriert Wasser in nanoporösem Gestein nicht bei null Grad Celsius, sondern erst bei deutlich tieferen Temperaturen.
Researchers succeeded in the measurement of ascorbic acid as the anti-oxidant existing in natural and medical samples through electrochemical method and modification of carbon paste electrode by using carbon nanotubes.
Researchers in Japan have demonstrated that when optical defect particles are introduced into a thin film made of homogenized zinc oxide particles obtained by the submicrometer-sized spherical particle production method (laser-induced melting method), the film functions as a random laser with superior lasing properties.
