Squeezed nanocrystals: A new model predicts their shape when blanketed under graphene

Scientists have developed a model for predicting the shape of metal nanocrystals or 'islands' sandwiched between or below two-dimensional (2D) materials such as graphene. The advance moves 2D quantum materials a step closer to applications in electronics.

Nanotechnology fabrics that protect against chemical warfare agents

To protect against toxic industrial chemicals and chemical warfare agents, researchers are creating textile coatings using water-stable metal-organic frameworks.

Mystery of negative capacitance in perovskite solar cells solved

Scientists reveal the origin of apparently high and even negative capacitance values observed in perovskite solar cells.

Carbon dioxide to methanol conversion with highly efficient nanocatalyst

Chemists have developed a highly efficient nanostructured catalyst based on zinc and silver that can convert carbon dioxide, an environmental pollutant and greenhouse gas, to methanol for use as chemical feedstock and fuel.
