Vibrating grains might create new designer coatings

This laser ultrasonic setup allows the team to observe vibrations of microscale granular crystals. (Credit: Dennis Wise/University of Washington)   On the microscale, granular materials interact in remarkably complex ways. That complexity makes them one of the least understood forms...

Grime-proof coating repels just about everything

A researcher pours hexadecane oil onto a glass slide with a superomniphobic coating. The petroleum based, highly viscous lubricant slides easily off the slide, opening up applications like self-cleaning windows, ink jet printers, and microfluidic devices. (Credit: Robert Coelius, Michigan...

Fabric can repair itself and neutralize toxins

Engineers are developing fabrics for protective suits that not only self-heal but also shield people from toxic materials. They make the fabrics by dipping them in a series of liquids to create layers of material to form a self-healing, polyelectrolyte layer-by-layer coating....
