Quantum effect triggers unusual material expansion

You know how you leave space in a water bottle before you pop it in the freezer—to accommodate the fact that water expands as it freezes? Most metal parts in airplanes face the more common opposite problem. At high altitudes ...

Shifting dimensions: Exciting excitons in phosphorene

Since its discovery in 2014, phosphorene—a sheet of phosphorus atoms only a single atom thick—has intrigued scientists due to its unique optoelectronic anisotropy. In other words, electrons interact with light and move ...

Mechanically controllable nonlinear dielectrics

Strain-sensitive barium strontium titanate (Bax-Sr1-x-TiO3) perovskite systems are widely used for their superior nonlinear dielectric behaviors. In a new report on Science Advances, D.L. Ko and a research team in materials ...

Probing microscopic wiggles in squishy materials

The term "colloidal gel" may not be a household phrase, but examples of these materials are everywhere in our daily lives, from toothpaste and shower gel to mayonnaise and yogurt. Colloidal gels are mixtures of particles ...

Gold in limbo between solid and melted states

If you heat a solid material enough, the thermal energy (latent heat) causes the material's molecules begin to break apart, forming a liquid. One of the most familiar examples of this phase transition from a well-ordered ...

Explained: Why water droplets 'bounce off the walls'

University of Warwick researchers can now explain why some water droplets bounce like a beach ball off surfaces, without ever actually touching them. Now the design and engineering of future droplet technologies can be made ...

Simple self-charging battery offers power solutions for devices

A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved ...
