Researchers from the MESA+ Institute for Nanotechnology at the University of Twente, working with American researchers, have succeeded in using an electrical signal to control both the elastic and the magnetic properties of a nanomaterial at a very localized level.
For his PhD at the Georgia Institute of Technology, University of Wisconsin-Madison Materials Science and Engineering Assistant Xudong Wang was part of a team that developed a piezoelectric nanogenerator and experimented with a variety of materials to power it.
Drugs based on engineered proteins represent a new frontier for pharmaceutical makers. Even after they discover a protein that may form the basis of the next wonder drug, however, they have to confront a long-standing problem: how to produce large quantities of the protein in a highly pure state. A research team may have found a new solution in an enzymatic 'food processor' they can activate at will.
A new paper describes a highly simplified model cell that not only sheds light on the way certain real cells generate electric voltages, but also acts as a tiny battery that could offer a practical alternative to conventional solid-state energy-generating devices.
If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the Lawrence Berkeley National Laboratory who have found a simple and yet powerfully robust way to induce nanoparticles to assemble themselves into complex arrays.
An ancient Confucian philosopher once said, 'I love the lotus because while growing from mud, it is unstained.' Now, almost one thousand years since Zhou Dunyi wrote these lines in China, scientists finally understand how the plant keeps itself clean and dry. It took an ultra high speed camera, a powerful microscope and an audio speaker to unlock a secret that has puzzled scientists for ages.
Scientists who study RNA have faced a formidable roadblock: trying to examine RNA's movements in a living cell when they can't see the RNA. Now, a new technology has given scientists the first look ever at RNA in a live bacteria cell - a sight that could offer new information about how the molecule moves and works.
The National Institute of Standards and Technology (NIST), in collaboration with IEEE, is inviting university and collegiate student teams currently engaged in microrobotic, microelectronic or MicroElectroMechanical Systems (MEMS) research to participate in the 2010 NIST Mobile Microrobotics Challenge.
A background paper on nanotechnology by Germany's Federal Environment Agency earlier this week triggered fearful headlines in some of the country's biggest newspapers. But the agency is now distancing itself from the coverage.
The biological safety of nanotechnology, in other words, how the body reacts to nanoparticles, is a hot topic. Researchers at Lund University in Sweden have managed for the first time to carry out successful experiments involving the injection of so-called nanowires.
Researchers at the Georgia Institute of Technology have won a $6.5 million grant to develop improved components that will boost the efficiency of electric propulsion systems used to control the positions of satellites and planetary probes.
Researchers at the Heinz Nixdorf Chair for Medical Electronics at the Technische Universitaet Muenchen have developed a new test process for cancer drugs. With the help of microchips, they can establish in the laboratory whether a patient's tumor cells will react to a given drug.
