Engineers use heat-free technology to make metallic replicas of a rose's surface texture
Nature has worked for eons to perfect surface textures that protect, hide and otherwise help all kinds of creatures survive.

Many natural surfaces can rapidly shed water droplets due to their water-repellent functionality. In 1945, scientists Cassie and Baxter linked the water-repellent function of natural surfaces to their surface textures. The ...
Doping is commonly used to improve performance in semiconducting devices but has not previously been successful for electron transporting or n-type, organic electronic materials. Now, an approach developed by KAUST uses a ...

Just as cloning in biology allows for the creation of one or more replicas of the exact same genes, seeded growth in chemistry can produce a very large metal foil with the exact same surface texture as that of a seeded one. ...

A dolphin is obviously not a golf ball. However, many scientists believed that the way one slips through the water and the other through the air owed to the same cause: similarities in surface texture and their effect on ...

The word starch brings to mind for many people either a food component or something used to stiffen clothing—but its use covers much territory. Starch is used in a wide variety of food and non-food settings. In fact, the ...

You may not know it, but you probably spend several hours a day looking at nematic liquid crystals; they are used in virtually every smartphone, computer and TV screen. They are liquids composed of elongated molecules, which ...
