Electrical fields play a pivotal role in numerous cases in both nature and technical areas: by changing the electrical field, impulses of nerves are transmitted and modern data storage operates by saving electrical charges the so-called Flash Memories. An ultra-precise reading of electrical fields, however, is still a challenge for physical measurement techniques. Researchers from the University of Stuttgart succeeded in measuring electrical fields with the aid of one single defect center in diamond.
Conventional silicon-based rigid solar cells generally found on the market are not suitable for manufacturing moldable thin-film solar cells, in which a transparent, flexible and electrically conductive electrode collects the light and carries away the current. A woven polymer electrode developed by Empa has now produced first results which are very promising, indicating that the new material may be a substitute for indium tin oxide coatings.
New research suggests that currently available types of synthetic skin may now be good enough to imitate animal skin in laboratory tests, and may be on their way to truly simulating human skin in the future.
A team from Pitt, UW-Madison and HP Labs reports in Nature Nanotechnology a 1.5-nanometer single-electron transistor that could lead to long-lasting, ultradense computer memories, quantum computers and advanced electronics.
ICE Publishing, the publishing division of the Institution of Civil Engineers, today announces the launch of a major new flagship journal series: ICE Science. By publishing at the intersection of many scientific disciplines this new series aims to inspire the cross-fertilization of ideas and drive forward knowledge in the areas of materials science, biomaterials, nanotechnology and energy.
In February 2011, a new European project called Seebetter was launched with the goal to design and build a high-performance silicon retina using advanced photodetector and packaging technology. It is expected that these new vision sensors will revolutionize artificial vision and find wide applications in industry.
Melding nanotechnology and medical research, Sandia National Laboratories, the University of New Mexico, and the UNM Cancer Research and Treatment Center have produced an effective strategy that uses nanoparticles to blast cancerous cells with a melange of killer drugs.
To date, plasmonic properties have been limited to nanostructures that feature interfaces between noble metals and dielectrics. Now, researchers have shown that plasmonic properties can also be achieved in the semiconductor nanocrystals known as quantum dots. This discovery should make the field of plasmonics even hotter.
With two recent studies, imec scientists contribute to the field of label-free DNA sensing. The measurement technique they have refined is based on the fact that metallic films and nanoparticles absorb the light of nearby light-emitting fluorophores. In one study, the quenching and enhancement of the emitted light was studied and quantified with a wide range of gold nanoparticles and DNA hairpin probes. In a second study and using similar probes, the technique was used to demonstrate a functional label-free genosensor.
A new process flow to fabricate FinFETs in bulk Si has shown significant advancements in critical FinFET fabrication steps. Key issue of the new fabrication method is the use of a plasma-free dry oxide removal process. FinFETs, obtained with this new integration scheme and co-integrated with planar CMOS in the same wafer, showed good morphological and electrical characteristics.
Imec, together with some of its partners in the Advanced Lithography Program, has demonstrated the need for improved capability of the EUV supplier community to detect printing mask blank defects. And together with Zeiss SMS, a compensation technique to mitigate such defects has been demonstrated experimentally.
There are numerous materials which become superconducting at ultralow temperatures. However, this property competes with ferromagnetism which normally suppresses superconductivity. This does not happen with a material consisting of the elements bismuth and nickel with a diameter of only a few nanometers.
Researchers at North Carolina State University have found one of the first roadblocks to utilizing graphene by proving that its conductivity decreases significantly when more than one layer is present.
