Copying the small structures of Salvinia leaves

Several plants and animals have evolved surfaces with long-term (i.e., days to months) air-retainability to prevent wetting and submersion. One example is Salvinia, a plant floating on water. The secret "how do they maintain ...

Ultra-thin, gas-tight coatings for PET bottles

If polymers are specifically made to form and deposit on the surfaces surrounding the plasma, they can be coated in a targeted manner. Thanks to this so-called plasma enhanced chemical vapor deposition, or PECVD for short, ...

Nobarrier to applications for a remarkable 2-D material

Mass production of large, uniform sheets of single-layer molybdenum disulfide, MoS2, is difficult, which limits its commercial application. A*STAR researchers have modified an existing manufacturing technique to enable the ...

New catalytic effect discovered for producing gallium oxide

Semiconducting oxides are a new class of materials that are currently enjoying great attention in the field of semiconductor technology. Gallium oxide is the archetypal example for its ability to handle extremely high voltages ...
