Superheroes, foods and apps bring a modern twist to the periodic table
Many students, especially non-science majors, dread chemistry. The first lesson in an introductory chemistry course typically deals with how to interpret the periodic table of elements, but its complexity can be overwhelming to students with little or no previous exposure. Now, researchers reporting in ACS' Journal of Chemical Education introduce an innovative way to make learning about the elements much more approachable -- by using ''pseudo'' periodic tables filled with superheroes, foods and apps.

Observing the ultrafast motion of atoms and electrons
Photo-induced electron transfer is central to numerous physical processes, for instance in the magnetization of materials. The quest to understand and control this ultrafast process has long been pursued in vain, with no answer to the question of whether electrons induce atomic motion, or vice versa. To answer this question, the atomic equivalent of the paradox of the chicken and the egg, a consortium of scientists used an X-ray laser (X-FEL) located in Stanford. (2020-12-07)

On the road to conductors of the future
Superconducting wires can transport electricity without loss. This would allow for less power production, reducing both costs and greenhouse gasses. Unfortunately, extensive cooling stands in the way, because existing superconductors only lose their resistance at extremely low temperatures. In the journal Angewandte Chemie, scientist have now introduced new findings about hydrogen sulfide in the H(3)S form, and its deuterium analogue D(3)S, which become superconducting at the relatively high temperatures of -77 and -107 ┬░C, respectively. (2020-09-14)

Engaging undergrads remotely with an escape room game
To prevent the spread of COVID-19, many universities canceled classes or held them online this spring -- a change likely to continue for many this fall. As a result, hands-on chemistry labs are no longer accessible to undergraduate students. In a new study in the Journal of Chemical Education, researchers describe an alternative way to engage students: a virtual game, modeled on an escape room, in which teams solve chemistry problems to progress and 'escape.' (2020-08-12)

Graphene: It is all about the toppings
The way graphene interacts with other materials depends on how these materials are brought into contact with the graphene. The appropriate atoms are brought into contact with the graphene in such a way that they 'grow' on the graphene in the desired crystal structure. Until now the mechanisms of the 'growth' of such other materials on graphene have often remained unclear. A new study shows now how indium oxide grows on graphene. (2020-07-08)

Material research: New chemistry for ultra-thin gas sensors
The application of zinc oxide layers in industry is manifold and ranges from the protection of degradable goods to the detection of toxic nitrogen oxide gas. Such layers can be deposited by atomic layer deposition (ALD) which employs typically chemical compounds, or simply precursors, which ignite immediately upon contact with air, i.e. are highly pyrophoric. An interdisciplinary research team at Ruhr-Universit├Ąt Bochum (RUB) has now established a new fabrication process based on a non-pyrophoric zinc precursor t (2020-07-01)

A new view of microscopic interactions
When two cars collide at an intersection -- from opposite directions -- the impact is much different than when two cars -- traveling in the same direction -- 'bump' into each other. In the laboratory, similar types of collisions can be made to occur between molecules to study chemistry at very low temperatures, or 'cold collisions.' A team of scientists led by Arthur Suits at the University of Missouri has developed a new experimental approach to study chemistry using these cold 'same direction' molecular collisions.
