Structural colors, without the shimmer

Structural colors, like those found in some butterflies' wings, birds' feathers and beetles' backs, resist fading because they don't absorb light like dyes and pigments. However, the iridescence that enhances their beauty ...

Surface science concepts are up for revision

The textbook directions for characterizing the wetting properties of solid surfaces are likely to change as KAUST researchers demonstrate that conventional tests can be misleading.

Exploding stars make key ingredient in sand, glass

We are all, quite literally, made of star dust. Many of the chemicals that compose our planet and our bodies were formed directly by stars. Now, a new study using observations by NASA's Spitzer Space Telescope reports for ...

New discovery shows glass made from exploding stars

The next time you're gazing out of the window in search of inspiration, keep in mind the material you're looking through was forged inside the heart of an exploding ancient star.

Designer emulsions

ETH material researchers are developing a method with which they can coat droplets with controlled interfacial composition and coverage on demand in an emulsion in order to stabilise them. In doing so they are fulfilling ...

Enhanced oil recovery with nanoparticles

A mixture of nanoparticles and water can be used in the nano-water alternating gas approach (NWAG) to enhance oil recovery from an oil field. Now, the wettability of rock, relative permeability curves, and the interfacial ...

Silicon dioxide

The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. It is a principal component of most types of glass and substances such as concrete. Silica is the most abundant mineral in the Earth's crust.
