A University at Buffalo-led research team is a 3D printing method called stereolithography and jelly-like materials known as hydrogels to develop a 3D printing method that's 10-50 times faster than the industry standard. The team says its progress toward 3D-printed human tissue and organs -- biotechnology that could eventually save countless lives lost due to the shortage of donor organs.
A team of researchers from Nagoya University, Japan, and Technical University of Darmstadt have developed a technique for quantitatively studying the effect of light on nanoscale mechanical properties of thin wafers of semiconductors or any other crystalline material. The group has found clear evidence that propagation of dislocations - slippages of crystal planes - in semiconductors is suppressed by light. The likely cause is interaction between dislocations and electrons and holes excited by the light.
University of Tsukuba and Institute of High Pressure Physics scientists mapped the spin-density distribution of electrons travelling through a molybdenum disulfide transistor cooled to almost absolute zero. This work may help advance the field of spin-based electronics that would be faster and more efficient compared with current devices.
Professor Byoungwoo Kang develops a high-density cathode material through controlling local structures of the Li-rich layered materials.
Columbia Engineering researchers report that they developed a new, efficient way to modulate and enhance an important type of nonlinear optical process: optical second harmonic generation--where two input photons are combined in the material to produce one photon with twice the energy--from hexagonal boron nitride through micromechanical rotation and multilayer stacking. Their work is the first to exploit the dynamically tunable symmetry of 2D materials for nonlinear optical applications.
COSMIC, a multipurpose X-ray instrument at Berkeley Lab's Advanced Light Source, has made headway in the scientific community since its launch less than 2 years ago, with groundbreaking contributions in fields ranging from batteries to biominerals.
Using thin films -- no more than a few pieces of notebook paper thick -- of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow.
Experimental and theoretical physicists investigated the behavior of magnetic whirls within nanoscale geometric structures.
Japanese researchers performed computation of reaction kinetic information from first-principles calculations based on quantum mechanics, and developed methods and programs to carry out kinetic simulations without using experimental kinetic results. This method is expected to accelerate search for various materials to achieve a carbon-free society.
Metal organic framework helps silver catalyst to turn greenhouse gas into useful chemical feedstock.
