The novel mechanism may provide a new route for using multiferroic materials for the application of RAM (random access memories) in computers and other devices, such as printers.
An international partnerships is aiming to develop robust fingerprint sensors with resolution beyond today’s 500 dpi international standards, the minimum required by the U.S. Federal Bureau of Investigation. The new platform uses vertical piezoelectric nanowire matrices designed using multiphysics modeling software.
An international team has recently unveiled a superconducting pairing mechanism in calcium-doped graphene. The pairing, which was using a angle-resolved photoemission spectroscopy method, is important because graphene is easily doped or functionalized with chemicals, allowing scientists to more fully explore the nature of superconductivity.
Engineers are increasingly turning to plasmonic color filters (PCFs) to create and control a broad spectrum of colors for imaging applications. However, PCF light transmission efficiency has been limited to only about 30%, less than half the rate of conventional filters. Researchers have now developed a new PCF scheme that achieves a transmission efficiency of 60 to 70%.
Computational biologists in Austria have recently shown that the common practice of averaging is not always a good thing when it comes to analyzing protein crystal structures. A study shows that protein structures could be more dynamic and heterogeneous than current methods of x-ray analysis suggest.
NIST and American Univ. researchers report in a new study that the bench-scale test widely used to evaluate whether a burning cigarette will ignite upholstered furniture may underestimate the tendency of component materials to smolder when these materials are used in sofas and chairs supported by springs or cloth. The study comes as regulations and methods for evaluating ignition in furniture are undergoing scrutiny.
Inspired by tiny particles that carry cholesterol through the body, Massachusetts Institute of Technology chemical engineers have designed nanoparticles that can deliver snippets of genetic material that turn off disease-causing genes. This approach, known as RNA interference, holds great promise for treating cancer and other diseases. However, delivering enough RNA to treat the diseased tissue has proven difficult.
Materials experts in Ireland have developed a new germanium nanowire-based anode that has the ability to greatly increase the capacity and lifetimes of lithium-ion batteries. The typical lithium-ion battery on the market today is based on graphite, which has a relatively low capacity for energy storage. Restructuring the germanium replacement material into nanowires produces a stable, porous battery material.
U.S. Army-sponsored researchers have discovered a process for simultaneously storing and dissipating energy within structures that could lead to design rules for new types of active, reconfigurable materials. The study method was derived from an examination of how a species of South American fire ant collectively entangle themselves to form an active structure capable of changing state from a liquid to a solid when subject to applied loads.
European scientists from both academia and industry have begun an ambitious new research project focused on an alternative approach to extend Moore's Law. The research project, coordinated IBM Research in Zurich and called COMPOSE³, is based on the use of new materials to replace today's silicon, and on taking an innovative design approach where transistors are stacked vertically, known as 3-D stacking.
Topological insulators have been of great interest to physicists in recent years because of unusual properties that may provide insights into quantum physics. But most analysis of such materials has had to rely on highly simplified models. Now, a team of researchers at Massachusetts Institute of Technology has performed a more detailed analysis that hints at the existence of six new kinds of topological insulators.
Lawrence Berkeley National Laboratory researchers have produced the first detailed look at the 3-D structure of the Cas9 enzyme and how it partners with guide RNA to interact with target DNA. The results should enhance Cas9’s value and versatility as a genome-editing tool.
Lead-free BaTiO3 and KNbO3 ferroelectrics have been known and studied for more than 60 years. However, recent scanning x-ray diffraction studies at Argonne National Laboratory have shown new low-symmetry intermediate phases in these materials that lend a thermotropic character to otherwise well-known phase transitions. The findings show that these transitions in ferroelectrics are closely coupled to the underlying domain microstructure.
Cars inch forward slowly in traffic jams, but molecules, when jammed up, can move extremely fast. New research by Northwestern Univ. researchers finds that water molecules traveling through tiny carbon nanotube pipes do not flow continuously but rather intermittently, like stop-and-go traffic, with unexpected results.
An international team of researchers from France and the United States have devised an entirely new way to synthesize graphene ribbons with defined, regular edges, allowing electrons to flow freely through the material. Demonstrating this phenomenon at room temperature, the material was shown to permit electron flow up to 200 times faster than through silicon.
It's not quite the bionics of science fiction, but European researchers have created a robotic hand that gave an amputee a sense of touch he hadn't felt in a decade. The experiment lasted only a week, but it let the patient feel if different objects were hard or soft, slim or round, and intuitively adjust his grasp.
Texas Advanced Computing Center recently reported the results of several massive numerical simulations charting the forces of the universe in its first hundreds of millions of years. The study, which used some of the world's most powerful supercomputers, has refined our understanding of how the first galaxies formed, and, in particular, how metals in the stellar nurseries influenced the characteristics of the stars in the first galaxies.
Working on the cutting edge of a newly emerging area of solar-cell research, Univ. of California, Los Angeles engineers have invented a new process for manufacturing highly efficient photovoltaic materials that shows promise for low-cost industrial production. The new process uses so-called perovskite materials, which in the past few years have significantly advanced scientists' efforts to create the next generation of solar cells.
We all learn in high school science about the dual nature of light—that it exists as both waves and quantum particles called photons. It’s this duality of light that enables the coherent transport of photons in lasers. Sound at the atomic-scale has the same dual nature, existing as both waves and quasi-particles known as phonons. Does this duality allow for phonon-based lasers?
Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature—a property known as ballistic transport. Research reported that electrical resistance in nanoribbons of epitaxial graphene changes in discrete steps following quantum mechanical principles.
Researchers at Tyndall National Institute in Ireland have produced the first ever atom-by-atom simulation of nanoscale film growth by atomic layer deposition (ALD), a thin-film technology used in the production of silicon chips. The accomplishment required the acquisition of the complete set of hundreds of ALD reactions at the quantum mechanical level.
By sandwiching a biological molecule between sheets of graphene, researchers at the Univ. of Illinois at Chicago have obtained atomic-level images of the molecule in its natural watery environment. Researchers typically rely on relatively thick windows of silicon nitrate to protect specimens in a vacuum environment of an electron microscope, but the atomically-thin graphene sheets promise a major improvement.
A team NIST scientists, with collaborators elsewhere, has achieved a five-fold reduction in the dominant uncertainty in an experiment that measured the mean lifetime of the free neutron, resulting in a substantial improvement of previous results. However, the accomplishment reveals a puzzling discrepancy when compared to different method, and researchers are planning to re-run the experiment in upgraded form.
A Texas bioengineer has received a four-year, $1.4 million National Institutes of Health grant to create a nanoparticle system to shore up arterial walls following angioplasty and stenting procedures to treat coronary arterial disease.
