Flexibel, druckbar und preiswert: Elektronikbauteile, deren Aufbau auf Nanopartikeln und organischen Molekuelen beruht, erobern zunehmend den Markt. Drei Beispiele fuer Anwendungen zeigt der Exzellenzcluster Engineering of Advanced Materials (EAM) der Universitaet Erlangen-Nuernberg auf der Hannover Messe vom 19. - 23. April 2010.
A working group headed by Professor Rainer Waser from Forschungszentrum Juelich and RWTH Aachen University has developed a novel switching concept and the related technology for so-called memristor chips. With their research findings, the scientists are preparing for a paradigm shift in the architecture of computer chips.
Superschnell und leistungsstark: So sollen Quantencomputer einmal sein. Doch vor der Realisierung dieses voellig neuen Computertyps stehen noch technische Huerden. Ueber Fortschritte auf diesem Gebiet berichten Physiker der Uni Wuerzburg.
The 2010 Korea-China joint research program, 'New Photovoltaic Polymers and Advanced Flexible Plastic Solar Cells', was officially initiated on April 15-16, 2010 at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences.
Transistors, the cornerstone of electronics, are lossy and therefore consume energy. Researchers from the ETH Zurich and EPF Lausanne have developed transistors targeting high switching speeds and higher output powers. The devices can be used more efficiently as conventional transistors, so as to reduce energy consumption and CO2 emissions.
We invite Authors to participate with contributions in all topics related to Neuroengineering, from novel (nano)materials interfacing the nervous system or as tools for basic research, to novel enabling technologies, and from basic neurobiology and electrophysiology to neuroprosthetics. We aim at covering topics across levels of investigations, from the single-neuron to the network- and the system levels.
Scientists have developed a brain implant that essentially melts into place, snugly fitting to the brain's surface. The technology could pave the way for better devices to monitor and control seizures, and to transmit signals from the brain past damaged parts of the spinal cord.
Using easily prepared gold nanocages that are able to escape from the blood stream and accumulate in tumors, a team of investigators from the Washington University in St. Louis has shown that they can use laser light to kill human tumors in mice.
Researchers have long known that certain peptides are capable of killing cells by inserting themselves into the cell membranes and disrupting normal membrane structure and function. Now, researchers have learned how to deliver these cytotoxic peptides to tumor cells using self-assembling nanofibers that can slip into cancer cells and allow the toxic peptides to do their job from inside the cell.
One of the promises of nanoparticles as delivery agents for cancer therapeutics is that they will attack tumors while sparing healthy tissue from the damage normally associated with today's anticancer therapies. That promise is closer to realization thanks to the results of a study in which tumor-bearing mice were treated with a single dose of radioactive gold nanoparticles.
A multi-institutional team of researchers and clinicians has published the first proof that a targeted nanoparticle can traffic into tumors, deliver double-stranded small interfering RNAs (siRNAs), and turn off the production of an important cancer protein using a mechanism known as RNA interference (RNAi).
