The Italians have a colorful expression – to make a hole in water – to describe an effort with no hope of succeeding. Researchers at Queen's University Belfast (QUB), however, have seemingly managed the impossible, creating a class of liquids that feature permanent holes at the molecular level. The properties of the new materials are still largely unknown, but what has been gleaned so far suggests they could be used for more convenient carbon capturing or as a molecular sieve to quickly separate different gases.
Scientists have discovered that a bacterium called Thiomicrospira crunogena can produce carbonic anhydrase, an enzyme that can convert carbon dioxide into bicarbonate. In a new study, scientists from the University of Florida highlight how the bacterium, found in deep-sea regions, could play a role in the race to find solutions to sequester industrial CO2 from the atmosphere.
Climate change has a huge impact on the health of the world's oceans. In an attempt to find a solution for carbon dioxide pollution in the oceans, nanoengineers at the University of California, San Diego have developed micromotors that autonomously move through water, removing CO2 and converting it into usable material.
Coffee grounds are not exactly noxious despoilers of the environment,
but many millions of tons of them are generated every year and simply
disposed of with other vegetable matter and food waste. Now, researchers
have devised a way to utilize this innocuous waste product to get rid of a much
more dangerous one. By modifying used coffee grounds into a
carbon capture material, the new product may provide a simple, inexpensive way to
remove a prolific
and harmful greenhouse gas from the atmosphere.
