Titanium oxide material can remove toxic dyes from wastewater

Discharged in large quantities by textile, cosmetic, ink, paper and other manufacturers, dyes carry high-toxicity and can bring potential carcinogens to wastewater. It's a major concern for wastewater treatment—but researchers ...

Students set to launch self-built rocket into space

The Hybrid Engine Development (HyEnD) student team at the University of Stuttgart has spent around three years developing, manufacturing, and testing its hybrid rocket. In mid-April, the rocket will be launched into space ...

Earth's inner core may be oxygen-rich

Oxygen is the key substance for life and one of the most abundant elements in the Earth. However, it's still unknown whether oxygen is present (and in which form it may exist) in the inner core, which is composed of almost ...

Energy storage materials built from nano-sized molecular blocks

Molecules of the rare metallic element niobium can be used as molecular building blocks to design electrochemical energy storage materials. Mark Rambaran, Department of Chemistry at Umeå University, presents in his thesis ...
