Ions in molten salts can go 'against the flow'
In a new article published in the scientific journal Communications Chemistry, a research group at Uppsala University show, using computer simulations, that ions do not always behave as expected. In their research on molten salts, they were able to see that, in some cases, the ions in the salt mixture they were studying affect one another so much that they may even move in the ''wrong'' direction - that is, towards an electrode with the same charge.

Fluoride to the rescue?
Scientists have long been aware of the dangerous overuse of antibiotics and the increasing number of antibiotic-resistant microbes that have resulted. While over-prescription of antibiotics for medicinal use has unsettling implications for human health, so too does the increasing presence of antibiotics in the natural environment. The latter may stem from the improper disposal of medicines, but also from the biotechnology field, which has depended on antibiotics as a selection device in the lab. (2021-01-04)

Stopping tooth decay before it starts -- without killing bacteria
Eating sugar or other carbohydrates after dental cleanings causes oral bacteria to quickly rebuild plaque and to produce acids that corrode tooth enamel, leading to cavities. Today, scientists report a treatment that could someday stop plaque and cavities from forming in the first place, using a new type of cerium nanoparticle formulation. The researchers will present their results at the American Chemical Society Fall 2020 Virtual Meeting & Expo. (2020-08-17)

This, however, is only half the story: Every electronic device consists of multiple materials. So the ultra-thin semiconductors have to be paired with ultra-thin insulators. Scientists in Vienna have now found out how to do this. (2020-07-13)

Materials scientists drill down to vulnerabilities involved in human tooth decay

The discovery could lead to a better understanding of human tooth decay as well as genetic conditions that affect enamel formation. (2020-07-01)

Helicopter or cartwheel?
What happens when a molecule collides with a surface? Researchers at Swansea University have shown that the orientation of the molecule as it moves - whether it is spinning like a helicopter blade or rolling like a cartwheel - is important in determining what happens in the collision. The interaction of molecules with surfaces is important for many fields: plant fertilizers and chemicals, industrial catalysts, atmospheric chemical reactions, and even - in space - the processes through which a star is born.

A possible end to 'forever' chemicals
Synthetic chemicals known as per- and polyfluoroalkyls, or PFAS, contain bonds between carbon and fluorine atoms considered the strongest in organic chemistry. Unfortunately, the widespread use of these nonbiodegradable products since the 1940s has contaminated many water supplies across America. Engineers at UC Riverside have now shown in modeling experiments that using excess electrons shatters the carbon-fluorine bond of PFAS in water, leaving by-products that might even accelerate the process.
