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.
Synthetically created melanin can be used as a toxin adsorbent when applied to fabric. New material protected fabric from nerve gas penetration. Examples in nature lead researchers to believe these materials "exist out there".
Scientists reported the oxygen adsorption-induced dispersion of metallic Ag nanoclusters in a typical oxidative atmosphere.
Experimental and theoretical physicists investigated the behavior of magnetic whirls within nanoscale geometric structures.
A significant advance in 'optical tweezer' technology, developed by researchers at the UTS Institute for Biomedical Materials and Devices, will help boost biomedical research.
As light as possible and as strong as possible at the same time. These are the requirements for modern lightweight materials, such as those used in aircraft construction and the automotive industry. A research team from Helmholtz-Zentrum Geesthacht (HZG) and Hamburg University of Technology (TUHH) has now developed a new materials' design approach for future ultralight materials: Nanometer-sized metal struts that form nested networks on separate hierarchical levels provide amazing strength.
Tiny photonic devices could be used to find new exoplanets, monitor our health, and make the internet more energy efficient. Researchers from Chalmers University of Technology, Sweden, now present a game changing microcomb that could bring advanced applications closer to reality. The new microcomb is a coherent, tunable and reproducible device with up to ten times higher net conversion efficiency than the current state of the art.
Scientists in China present a new nanoscale AI optical circuit trained to perform unpowered all-optical inference at the speed of light for enhanced authentication solutions. By combining smart optical devices with imaging sensors, the scientists empower the sensors to perform complex functions as simply as putting glasses on them, achieving a neural density equal to 1/400 that of human brain and a computational power more than ten orders of magnitude larger than electronic processors.
