In future, fewer environmentally harmful chemicals are to be used in the microstructuring of glass. Whether electric cars, smartphones or smart homes - the demand for semiconductors is constantly growing and with it the ecological footprint of the electronics industry.

"Nature" Study: Phosphorene Nanoribbons Combine Magnetic and Semiconductor Properties at Room Temperature A recent study published in the scientific journal Nature has examined the remarkable properties of phosphorene nanoribbons (PNRs). These atom-thin ribbons made of phosphorus exhibit both magnetic and semiconductor properties at room temperature, making them promising candidates for future electronic applications and paving the way for a new generation of energy-efficient technologies.

McGill team discovers a surprising electrical effect that remains stable despite dramatic changes in temperature Electronic devices rely on materials whose electrical properties change with temperature, making them less stable in extreme conditions. A discovery by McGill researchers that challenges conventional wisdom in physics suggests that bismuth, a metal, could serve as the foundation for highly stable electronic components.

For the first time, scientists have 'photographed' a rare plasma instability, where high-energy electron beams form into spaghetti-like filaments.
