A Tufts University chemist has discovered a way to select specific surfaces of single-crystal ice for study, a long-sought breakthrough that could help researchers answer essential questions about climate and the environment. The discovery is detailed in the Proceedings of the National Academy of Sciences Online Early Edition, publishing the week of October 26 in advance of print.
Researchers from Massachusetts Institute of Technology (MIT), Xi’an Jiaotong University and Carnegie Mellon University amongst others have discovered that when nanoscale metal pieces are stretched in small amounts repeatedly, the material can be strengthened as crystal defects are eliminated. This new process is known as “cyclic healing.”
Atomically thin 2D sheets of conducting perovskite hybrids have been produced in solution. The crystals have conducting properties that make them a contender as a replacement for silicon.
An international team of researchers, including a geoscientist from Virginia Tech, has demonstrated how nature employs different pathways for crystal growth that outperform the classical, one-atom-at-a-time route.
A team of researchers at the Oak Ridge National Laboratory, Department of Energy, has integrated a new synthesis process with standard electron-beam lithography methods to create complex and scalable arrays of semiconductor heterojunctions in random patterns within a nanometer-thick semiconductor crystal. This unique process depends on converting patterned areas of a single-layer crystal into another layer of crystal. The study has been published in Nature Communications.
A team of international researchers has developed the first field effect transistor made of semiconducting black arsenic phosphorus in which arsenic replaces individual phosphorus atoms.
A team of researchers has developed a novel technique to make new, exotic materials using ultra-short laser-induced micro-explosions in silicon. Silicon is a material that is generally used in computer chips. The research team successfully focused lasers onto silicon which was embedded deep inside a clear silicon dioxide layer and blasted small cavities in the solid silicon reliably. The study has been published in Nature Communications.
The mother liquor from which a biomolecular crystal is grown will contain water, buffer molecules, native ligands and cofactors, crystallization precipitants and additives, various metal ions, and often small-molecule ligands or inhibitors. On average, about half the volume of a biomolecular crystal consists of this mother liquor, whose components form the disordered bulk solvent.
A team of researchers has shown that pressure provides a new way to produce novel phases and helps in investigating the links between structures and properties of molecular materials.
Researchers at Princeton University have performed an experiment which has demonstrated the Hall Effect in a group of quantum materials known as 'frustrated magnets'.
