New fuel cell technology runs on solid carbon

05/02/2018

Advancements in a fuel cell technology powered by solid carbon could make electricity generation from coal and biomass cleaner and more efficient, according to a paper published this week. Innovations in the anode, the electrolyte and the fuel allow the fuel cell to utilize more carbon, operate at lower temperatures and show higher maximum power densities than earlier direct carbon fuel ...

User experiment at BESSY II: Complex tessellations, extraordinary materials

05/02/2018

An international team of researchers lead by the Technical University of Munich (TUM) has discovered a reaction path that produces exotic layers with semiregular structures. These kinds of materials are interesting because they frequently possess extraordinary properties. In the process, simple organic molecules are converted to larger units which form the complex, semiregular patterns. ...

2-D tin (stanene) without buckling: A possible topological insulator

02/02/2018

An international research team led by Nagoya University synthesized planar stanene: 2-D sheets of tin atoms, analogous to graphene. Tin atoms were deposited onto the Ag(111) surface of silver. The stanene layer remained extremely flat, unlike in previous studies wherein stanene was buckled. This leads to the formation of large area, high quality samples. Stanene is predicted to be a topological...

Piecework at the nano assembly line

02/02/2018

Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories. ...

Bio-renewable process could help 'green' plastic

01/02/2018

Plastics are often derived from petroleum, contributing to reliance on fossil fuels and driving harmful greenhouse gas emissions. To change that, Great Lakes Bioenergy Research Center (GLBRC) scientists are trying to take the pliable nature of plastic in another direction, developing new and renewable ways of creating plastics from biomass.

Perovskite solar cells: Mesoporous interface mitigates the impact of defects

31/01/2018

The nominal cell operating life of perovskite solar cells is strongly influenced by their inner architecture.This was shown by two scientists at the Helmholtz-Zentrum Berlin and the Technical University of Munich. They combined experiments with numerical simulations in order to explain this observation.
