TAPPI has announced keynote speakers for the 2011 TAPPI International Conference on Nanotechnology for Renewable Materials. The conference's technical focus includes both cellulose and renewable nanomaterials and their applications. The event will be held June 6-8, 2011 at the Sheraton Crystal City, Washington. D.C., USA.
Researchers at North Carolina State University have developed a cheap and easy method for assembling nanowires, controlling their alignment and density. The researchers hope the findings will foster additional research into a range of device applications using nanowires, from nanoelectronics to nanosensors, especially on unconventional substrates such as rubber, plastic and paper.
Nanotechnology is one of the key technologies of the 21st century. It is already of immense significance in medicine as well as industry. Together with the Vienna University of Technology and the University of Natural Resources and Applied Life Sciences Vienna, Danube University Krems has developed a postgraduate Master's program in nanobiosciences and nanomedicine which imparts interdisciplinary and practice-oriented knowledge in this sub-speciality.
A new survey shows that European companies want to hire more employees again, their sales have risen strongly, they are aiming for new overseas markets and looking out on the new business year with confidence. However, skills shortage and a persistent difficulty to raise capital may eventually restrict the industry's growth.
Rare earths are an expensive and necessary component of strong permanent magnets. However, their use for this purpose can be optimised and thereby reduced. This has been demonstrated in computer simulations by a Special Research Program funded by the Austrian Science Fund FWF.
From a single cell to a whole organism, the laser will play an increasingly important role in diagnosing and treating disease. So says a Duke University bioengineer who is using the latest applications of a technology invented 50 years ago to peer into the genetic material of cells, to detect the earliest signs of disease in a single cell, and to non-invasively and optically biopsy tissue inside the body for the tell-tale traces of cancer.
Quantensysteme werden als frustriert bezeichnet, wenn konkurrierende Wechselwirkungen nicht gleichzeitig befriedigt werden koennen. Einem Forschungsteam der Uni Wien und des Instituts fuer Quantenoptik und Quanteninformation gelang es, erstmals Quanteneffekte von komplexen Vielteilchensystemen zu simulieren.
Researchers in Japan have produced high-purity carbon nanotubes (CNTs) with a random network structure by applying the super growth technique. This CNT structure exhibits rubber-like viscoelasticity in a temperature range of -196 to 1000 C.
Electrical energy can be generated from a temperature difference in a circuit with suitable materials. In simulations, ETH Zurich scientists show which materials are most likely to succeed in a thermoelectric process.
Eine grundlegend neue Architektur fuer den Quantencomputer schlagen Innsbrucker Physiker um Rainer Blatt vor. Sie haben im Experiment erstmals die Funktion von Quantenantennen demonstriert. Diese machen es moeglich, Quanteninformation zwischen einzelnen Speicherzellen auf einem Computerchip auszutauschen.
In addition to flows of electrons, researchers are seeking options for the spin of electrons to be used in future information processing. In combination with these characteristics, a considerably larger volume of information can be stored than merely 'zero' and 'one'. Because this is difficult with individual atoms, physicists place 'artificial atoms' into solids. Through his participation, a research team has now has succeeded in an energy-state occupancy readout of those artificial atoms - using common interfaces to classic computers.
New research from the University of Pennsylvania demonstrates a more consistent and cost-effective method for making graphene, the atomic-scale material that has promising applications in a variety of fields, and was the subject of the 2010 Nobel Prize in Physics.
Last year, Intel unveiled its Core processor family that, for the first time, used a full-featured system-on-a-chip 32 nanometer process technology to complement the CPU-specific technology. If you have been wondering how small 32 nanometers are, Intel has prepared a fun fact sheet for you.
