Energy from microbes for drying sewage sludge

A new biodrying process from Siemens quickly converts sewage sludge into a usable form while saving energy. When dried with the new process, sludge from wastewater treatment can be used as fertilizer, dumped in landfills ...

Some polycrystal grain boundaries feel the heat more than others

Polycrystals are solid materials that are made up of lots of small crystals. The points where the crystals meet are known as grain boundaries (GBs). GBs are important because they can affect the way the solid behaves. However, ...

Turning fish waste into quality carbon-based nanomaterial

Thanks to their low toxicity, chemical stability, and remarkable electrical and optical properties, carbon-based nanomaterials are finding more and more applications across electronics, energy conversion and storage, catalysis, ...
