Lego-like chemical building blocks self-assemble into catalyst for hydrogen fuel cells: New material could replace expensive platinum catalysts used in hydrogen cars

ScienceDaily   -   General News Websites

What's better than platinum? In hydrogen fuel cells, the answer may be cofacial cobalt porphyrins. These self-assembled molecules -- which are great at facilitating a chemical reaction needed to produce power from hydrogen and oxygen -- could be t...

Cell-like nanorobots clear bacteria and toxins from blood

ScienceDaily   -   General News Websites

Engineers have developed tiny ultrasound-powered robots that can swim through blood, removing harmful bacteria along with the toxins they produce. These proof-of-concept nanorobots could one day offer a safe and efficient way to detoxify and decon...

How to draw a line narrower than a cold virus

Phys.org   -   Scientific News Websites

For the first time, a team demonstrated a technique that creates tiny, precise metallic shapes. They rastered a beam from a helium-ion microscope through a liquid precursor to induce chemical reactions. The reactions locally deposit high purity pl...

Lone water molecules turn out to be directors of supramolecular chemistry

ScienceDaily   -   General News Websites

A broken seal of a lab cuvette led an American researcher in the Netherlands to the origin of many an inexplicable result: the weather. Or the humidity, because this determines the water concentration in oils used as solvents, which was previously...

Paradoxically, environmental noise helps preserve the coherence of a quantum system

ScienceDaily   -   General News Websites

In work that could lead to scalable quantum computers, scientists have shown that thanks to the 'quantum Zeno effect,' with a three-particle system, that they can use dephasing -- a process that normally would reduce the coherence -- to paradoxica...
