Simulations from researchers in Japan provide new insights into the reactions occurring in solid-oxide fuel cells by using realistic atomic-scale models of the electrode active site based on microscope observations instead of the simplified and idealized atomic structures employed in previous studies. This better understanding of how the structures in the cells affect the reactions could give clues on ways to improve performance and durability in future devices.
A World-first study by Monash University, published in Nature Communications, has discovered a technique for creating stronger, lightweight magnesium alloys. This finding could be of significant benefit to the automobile and aerospace industries.
With high-energy X-rays, such as those that will be produced by the upgrade to Argonne's Advanced Photon Source comes a potential hitch -- the more penetrating the X-rays are, the higher a likelihood that researchers could run into problems with the image data. In a new study, researchers at Argonne have found a novel way to combat this image degradation.
The widespread adoption of thermoelectric devices that can directly convert electricity into thermal energy for cooling and heating has been hindered, in part, by the lack of materials that are both inexpensive and highly efficient at room temperature. Now researchers from the University of Houston and the Massachusetts Institute of Technology have reported the discovery of a new material that works efficiently at room temperature while requiring almost no costly tellurium, a major component of the current state-of-the-art material.
Porous metal-organic frameworks (MOFs) have many applications like carbon capture and water-cleaning. However, MOFs with large pores tend to collapse. Chemists and chemical engineers at EPFL have now solved the problem by adding small amounts of a polymer into the MOF pores, an act that impedes pore collapse.
Researchers at the Georgia Institute of Technology are working on membranes that could separate chemicals without using energy-intensive distillation processes.
A stealthy new drug-delivery system disguises chemotherapeutics as fat in order to outsmart, penetrate and destroy tumors. Thinking the drugs are tasty fats, tumors invite the drug inside. Once there, the targeted drug activates, immediately suppressing tumor growth.
Most magnets are rigid but have made great contributions to society and to modern industry, says Thomas Russell of UMass Amherst. But this award-winning innovator dreamed of more -- what if magnets could be soft and flowable as liquid to conform to a limited space? In Science this week, he and Xubo Liu from Beijing University of Chemical Technology, others at Berkeley National Lab and UC Berkeley, report on a simple way to transform paramagnetic ferrofluids -- plain metal particles in suspension -- into a magnetic state.
Scientists at Berkeley Lab have made a new material that is both liquid and magnetic, opening the door to a new area of science in magnetic soft matter. The new material could lead to a revolutionary class of printable liquid devices for a variety of applications from artificial cells that deliver targeted cancer therapies to flexible liquid robots that can change their shape to adapt to their surroundings.
Researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a graphene device that's thinner than a human hair but has a depth of special traits. It easily switches from a superconducting material that conducts electricity without losing any energy, to an insulator that resists the flow of electric current, and back again to a superconductor -- all with a simple flip of a switch.
