Complex, Scalable Arrays of Semiconductor Heterojunctions Hold Potential for Future Electronics

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.

Laser-Induced Micro-Explosions Create New, Exotic Materials

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.

Macromolecules Self-Assemble from Metastable, Supersaturated Solution into Crystals

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.

Study Reveals How Chameleons Control Nanocrystals to Change Color

A research team from the Sections of Biology and Physics of the Faculty of Science from the University of Geneva (UNIGE), Switzerland, has discovered the mechanisms that control and regulate the rapid and complex color changes in chameleons. Many chameleons display this phenomenon during social interactions. The research has been published in Nature Communications.
