From hard to soft: Making sponges from mussel shells

Scientists have discovered a spongy form of calcium carbonate (CaCO3), a material found in limestone, chalk, marble, and the shells of mussels and other shellfish. While most forms of calcium carbonate are hard minerals, ...

Thermal vision of snakes inspires soft pyroelectric materials

Converting heat into electricity is a property thought to be reserved only for stiff materials like crystals. However, researchers—inspired by the infrared (IR) vision of snakes—developed a mathematical model for converting ...

Researchers unveil sensor that rapidly detects COVID-19 infection

One feature of the COVID-19 virus that makes it so difficult to contain is that it can be easily spread to others by a person who has yet to show any signs of infection. The carrier of the virus might feel perfectly well ...

New design principles for spin-based quantum materials

As our lives become increasingly intertwined with technology—whether supporting communication while working remotely or streaming our favorite show—so too does our reliance on the data these devices create. Data centers ...

Scientists invent new sensing eye mask

From the team that invented physiology-sensing pajamas at the University of Massachusetts Amherst, now comes a new, lightweight eye mask that can unobtrusively capture pulse, eye movement and sleep signals, for example, when ...

Biphilic surfaces reduce defrosting times in heat exchangers

Ice formation and accumulation are challenging concerns for several industrial applications including heating ventilation air conditioning and refrigeration (HVAC&R) systems, aircraft, energy transmission, and transportation ...
