Scientists develop low-temperature resisting aqueous zinc-based batteries

03-Sep-2020

Aqueous zinc-based batteries (ZBBs) are widely used for portable and grid-scale applications due to their high safety, low cost and high energy density. However, the inhomogeneous zinc deposition on anode during charging and the zinc dendrite formation decrease the cycling stability of ZBBs. ...

Laser takes pictures of electrons in crystals

The experiments pave the way towards to deeply understand and eventually control the chemical and the electronic properties of materials

03-Jul-2020

Microscopes of visible light allow us to see tiny objects such living cells and their interior. Yet, they cannot discern how electrons are distributed among atoms in solids. Now researchers around Prof. Eleftherios Goulielmakis of the Extreme Photonics Labs at the University of Rostock and the ...

Efficient indium oxide catalysts designed for CO2 hydrogenation to methanol

Promising way to directly convert CO2 into methanol for industrial applications

23-Jun-2020

Catalytic hydrogenation of carbon dioxide (CO2) is a green and sustainable means of synthesizing commodity chemicals such as methanol. This conversion process is key to realizing the "methanol economy" or creating "liquid sunshine", both aspects of the circular economy. Recent studies revealed ...

Is the simplest chemical reaction really that simple?

Uncovered mechanism leads to clear quantum interference and verifies that Nature does "play dice"

18-May-2020

Most people think that quantum theory, which describes the motion of molecules and atomic and subatomic particles, is counterintuitive, since quantum mechanics describes behavior at odds with classical mechanics. Even Albert Einstein, who never accepted quantum mechanics, famously said that "He ...
