Manufacturing method paves way for commercially viable quantum dot-based LEDs
University of Florida researchers may help resolve the public debate over America's future light source of choice: Edison's incandescent bulb or the more energy efficient compact fluorescent lamp. It could be neither.
Silica microspheres in liquid crystals offer the possibility of creating every knot conceivable
Knots can now be tied systematically in the microscopic world. A team of scientists led by Uros Tkalec from the Jozef Stefan Institute in Ljubljana (Slovenia), who has been working at the Max Planck Institute ...
Exotic quantum crystal discovered
Nature knows two opposite types of solids: one that emerges upon compression from a liquid and a second that appears if the pressure on a liquid is reduced. While the former is typical for substances in our ...
Flowing structures in soft crystals
What is common to blood, ink and gruel? They are all liquids in which tiny particles are suspended so called colloids. In some of these liquids, the particles form groups (clusters), which ...
A bit of boron, a pinch of palladium: One-stop shop for the Suzuki reaction
Carbon-containing compounds are at the heart of organic chemistry, and carbon is the basis of all living matter. However, the so-called Suzuki reaction provides a simple means of creating carbon-carbon bonds to form compounds ...
