A new idea for refining biocrude

The high content of nitrogen-containing organic compounds (NOCs) in biocrude obtained from hydrothermal liquefaction of microalgae is one of the most concerning issues on the applications and environment. The biocrude obtained ...

Studying the mechanism of metal extraction with ionic liquids

The heaviest known elements are the so-called "superheavy" elements, those with atomic numbers greater than 103. These elements are found only in laboratories, where they are made by fusing together two lighter elements. ...

Preconditions for life already present 3.5 billion years ago

Microbial life already had the necessary conditions to exist on our planet 3.5 billion years ago. This was the conclusion reached by a research team after studying microscopic fluid inclusions in barium sulfate (barite) from ...

New universal carrier ink for 3-D printing

Researchers at ETH have produced a gel from cellulose fibers and biodegradable nanoparticles that liquefies when pressed through the nozzle of a 3-D printer, but then quickly returns to its original shape. Their invention ...

Impact of sea smell overestimated by present climate models

Leipzig. The formation of sulfur dioxide from the oxidation of dimethyl sulfide (DMS) and, thus, of cooling clouds over the oceans seems to be overvalued in current climate models. This concludes scientists from the Leibniz ...
