Lausanne tackles toxic soil after shock discovery

Lausanne, the capital of Olympic sport overlooking Lake Geneva, is reeling after discovering that much of its soil is polluted with toxic compounds belched out by an old incinerator.

Liquid crystal molecules form nano rings

At DESY's X-ray source PETRA III, scientists have investigated an intriguing form of self-assembly in liquid crystals: When the liquid crystals are filled into cylindrical nanopores and heated, their molecules form ordered ...

The circular structure dominating this Sentinel-2 image is Pilanesberg, the result of geological activity over more than a billion years. Once a massive volcanic complex towering over 7000 m tall, millions of years of erosion ...

Nano-notch sends self-assembling polymers into a spiral

A simple circular or hexagonal pit written into silicon can be used to generate self-assembling polymer spirals thanks to the addition of a tiny notch in the template, report scientists in the launch issue of Nano Futures.
