Healthy cells are renewed by dividing and dying off, but cell division in cancer cells goes unchecked because natural cell death is suspended. This happens because too many receptors for the growth factor EGF which are found on the surface of the cell join together to form pairs. These pairs start a signal chain into the cell, culminating in unrestricted growth. Now, nanoscientists have for the first time been able to show this pairing in human cancer cells on individual receptors using gold nanoparticles.
Am 1. November 2013 ist das von der Bergischen Universität Wuppertal koordinierte Projekt nanoCOPS (Nanoelectronic Coupled Problems Solutions) gestartet. Führende Experten aus Industrie und Wissenschaft in Europa wollen gemeinsam neue Methoden entwickeln, die ein verbessertes und erneuertes Design von integrierten Schaltungen ermöglichen.
A groundbreaking nanoparticle system which stimulates the growth of microalgae - a valuable resource used in the production of biofuels and medical compounds - has been developed by a team of Australian scientists.
Researchers from the National Institute of Standards and Technology (NIST) have joined with an international team to engineer and measure a potentially important new class of nanostructured materials for microwave and advanced communication devices. Based on NIST's measurements, the new materials - a family of multilayered crystalline sandwiches - might enable a whole new class of compact, high-performance, high-efficiency components for devices such as cellular phones.
The official Call for Papers have been issued for the 2014 Symposia on VLSI Technology and Circuits to be held at the Hilton Hawaiian Village June 9-12, 2014 (Technology) and June 10-13, 2014 (Circuits). The deadline for paper submissions to both conferences is January 27, 2014.
Scientists have developed a new technique for manufacturing high-efficiency, flexible, thin film solar cells from CIGS (copper indium gallium di-selenide) semiconductors. This has enabled them to achieve an efficiency of 20.4 percent for the conversion of sunlight into electrical energy. As the solar cells are deposited onto plastic foils, they could be produced on an industrial scale using cost-effective roll-to-roll manufacturing.
Scientists have realised the promise of carbon-based nanocomposites for lightweight, high-strength components with novel electrical and thermal properties through knowledge-based control of materials and processing.
With just a single atom, light can be switched between two fibre optic cables at the Vienna University of Technology. Such a switch enables quantum phenomena to be used for information and communication technology.
