Phys.org / Kitchen cling film helps build centimeter-scale ultrathin electronics and optics

As materials become thinner—now reaching the thickness of single atoms—it has become increasingly difficult to create sufficiently large sheets and transfer them without cracking them into tiny flakes. Recent work by a broad ...

Phys.org / Trees and microbes team up to improve nitrogen nutrient processes in higher CO₂ conditions

Forest trees growing in air containing higher levels of carbon dioxide (CO2) radically change the way they "cycle" nitrogen, a key plant nutrient, with implications for forests as a nature-based climate solution.

Phys.org / Beyond wrinkles: New rule explains why growing shapes suddenly crumple

Scientists have discovered a previously unknown law of geometry that explains why some growing surfaces, whether in nature or in engineered materials, suddenly stop being able to stay smooth and instead form dimples and folds. ...

Phys.org / Two attosecond flashes capture electrons in motion

Electronic motion sets the stage for virtually every light-induced process in nature, from the first step of a chemical reaction to the flow of charge in a solid. Yet these processes unfold so rapidly that they can be observed ...

Phys.org / Gold-MXene catalyst converts nitrate to ammonia using sunlight and 1.5 volts

Plants need nitrogen fertilizers, which are usually ammonia-based. Ammonia is therefore one of the most important chemical products. However, its production is currently extremely energy-intensive. An international team from ...
