Nanomaterials research could lead to new solutions for an age-old public health problem: how to separate bacteria from drinking water.
Most people cross borders such as doorways or state lines without thinking much about it. Yet not all borders are places of limbo intended only for crossing. Some borders, like those between two materials that are brought together, are dynamic places where special things can happen. For an electron moving from one material toward the other, this space is where it can join other electrons, which together can create current, magnetism or even light. Researchers have made fundamental discoveries at the border regions, called interfaces, between oxide materials.
Scientists have demonstrated a clever way of controlling electrical conductance of a single molecule, by exploiting the molecule
Northwestern University scientists have discovered that axons can operate in reverse: they can also send signals to the neuron cell body, too. Previously, it
It is now possible to see up to 28 differently labeled microbes in a single field of view, due to a new microscopy technique.
How does a scientist fuel his enthusiasm for chemistry after 60 years? By discovering a new energy source, of course.
More than 50 years after the invention of the laser, scientists at Yale University have built the world
Automobiles, military vehicles, even large-scale power generating facilities may someday operate far more efficiently thanks to a new alloy developed at the U.S. Department of Energy
In recent years, topological insulators have become one of the hottest topics in physics. These new materials act as both insulators and conductors, with their interior preventing the flow of electrical currents while their edges or surfaces allow the movement of a charge. Perhaps most importantly, the surfaces of topological insulators enable the transport of spin-polarized electrons while preventing the
Scientists have made the world’s first junctionless transistor even smaller. The transistor is the building block of the microchip.
Scientists have developed a simple and fast process to manufacture high-quality carbon nanotube-based thin film transistors (TFT) on a plastic substrate, enabling them to manufacture the world
Engineers and scientists collaborating at Harvard University and the MITRE Corporation have developed and demonstrated the world
Physicists from the University of Birmingham, with colleagues at Imperial College, London and Technical University of Denmark, have demonstrated an
In a complex feat of nanoengineering, a team of scientists at Kyoto University and the University of Oxford have succeeded in creating a programable molecular transport system, the workings of which can be observed in real time. The results, appearing in the latest issue of Nature Nanotechnology, open the door to the development of advanced drug delivery methods and molecular manufacturing systems.
Since the days of Darwin, the
