Phasing out a microscope's tricks

An instrument error can lead to complete misidentification of certain crystals, reports a KAUST study that suggests researchers need to exercise caution when using electron microscopes to probe two-dimensional (2-D) semiconductors.

Gently caressing atoms

Oxygen is highly reactive. It accumulates on many surfaces and determines their chemical behavior. At the Vienna University of Technology, scientists study the interaction between oxygen and metal oxide surfaces, which play ...

Tuning the surface gives variations to metal foils

Just as cloning in biology allows for the creation of one or more replicas of the exact same genes, seeded growth in chemistry can produce a very large metal foil with the exact same surface texture as that of a seeded one. ...

When predictions of theoretical chemists become reality

Thomas Heine, professor of theoretical chemistry at TU Dresden, together with his team, first predicted a topological 2-D polymer in 2019. Only one year later, an international team led by Italian researchers was able to ...

Plasma electrons can be used to produce metallic films

Computers, mobile phones and all other electronic devices contain thousands of transistors linked together by thin films of metal. Scientists at Linköping University, Sweden, have developed a method that can use the electrons ...

Atomic defect lines suppress deactivation of iron oxide catalysts

Catalysts, or substances that accelerate chemical reactions, have various industrial applications. One widely used catalyst in catalytic converters is palladium, which helps turn toxic carbon monoxide and hydrocarbons from ...

Two-dimensional metals open pathways to new science

An atomically thin materials platform developed by Penn State researchers in conjunction with Lawrence Berkeley National Lab and Oak Ridge National Lab will open a wide range of new applications in biomolecular sensing, quantum ...
