Electron Density

A porous organic crystal readily and reversibly adsorbs water, with dehydration occurring well below the freezing point of water, which could be seen by a change in colour.

Researchers at the University of Illinois Urbana-Champaign have detected the existence of a charge density wave of electrons that acquires mass as it interacts with the background lattice ions of the material over long distances.

Alcohols are widely applied in life sciences and the chemical industry. Selective hydrogenation of epoxides using hydrogen molecules as a reductant is considered to be one of the most facile and atom-economical strategies for alcohol synthesis. However, controlling the regioselective ring opening of epoxides remains a challenge.

Physicists have long suspected that hunks of metal could vibrate in a peculiar way that would be all but invisible. Now physicists have spotted these "demon modes."

Scientists from the Institute of Organic Chemistry and Biochemistry Prague, the Institute of Physics of the Czech Academy of Sciences, and Palacký University Olomouc, have once again successfully uncovered the mysteries of the world of molecules and atoms.

Using solar energy and photocatalysts to convert CO2 into high value-added chemicals can simultaneously alleviate the greenhouse effect and energy crisis. Single atom cocatalysts decoration has been demonstrated to be an effective strategy to improve the CO2 photocatalytic reduction efficiency.

Biosensors are developed from malleable hormone receptors.

This crystal lattice consists of a large number of unit cells with an identical atomic arrangement. In the elementary adiabatic picture, the motions of electrons in the crystal follow the motion of the atomic nuclei instantly, i.e., atomic nuclei and electrons are moving as a single entity. While this physical picture is valid for the inner, so-called core electrons of an atom it fails for the valence electrons,…

Much like people can learn more about themselves by stepping outside of their comfort zones, researchers can learn more about a system by giving it a jolt that makes it a little unstable—scientists call this "out of equilibrium"—and watching what happens as it settles back down into a more stable state.

Understanding the behavior of matter is crucial for advancing scientific fields like biology, chemistry, and materials science. X-ray crystallography has been instrumental in this pursuit, allowing scientists to determine molecular structures with precision.

The role of molecular junctions in nanoelectronics is most often associated with electronic transport; however, their precise characterization hinders their widespread development. Recently, most research has focused on investigating molecular junctions based on electronic characterization.

Scientists have made a significant contribution to understanding superconductivity by observing unusual charge waves within uranium ditelluride crystals. 'A place for everything and everything in its place'–making sense of order, or disorder, helps us understand nature. Animals tend to fit nicely

MIT's Kulik Lab has designed better ways of discovering and designing novel, environmentally benign, and energy-efficient materials for energy applications in a vast chemical space where molecular combinations that offer remarkable optical, conductive, magnetic, and heat transfer properties await discovery.

New antitubercular drugs are vital due to the spread of resistant strains of Mycobacterium tuberculosis. A research team from Skoltech, MIPT, and the Institute of Bioorganic Chemistry of the National Academy of Sciences of Belarus (IBOCH NAS) has obtained ultra-high-resolution structures of the M. tuberculosis cytochrome in complex with an inhibitor. The team's findings show that glycerol—a widely used additive to…

A laser pulse surfing in the wake of an electron beam pulse could get upshifted from visible to extreme ultraviolet light, simulations done at the University of Michigan have shown.

A paper published on Dec. 21 in Energy Material Advances reviews improvement strategies for the electrocatalytic activities of transition metal nitrides (TMNs) on hydrogen evolution reaction.

Scientists from University of Regensburg, Massachusetts Institute of Technology, Moscow institute of Physics and Technology, and University of Kansas have discovered abnormally strong light absorption in graphene. The effect arises from the conversion of ordinary electromagnetic waves into super-slow surface waves running through graphene. The observation is of fundamental interest and shows in an impressive way…

The challenge of regulating the electronic structures of metal single-atoms (M-SAs) with metal nanoparticles (M-NPs) lies in the synthesis of a definite architecture. Such a structure has strong electronic metal-support interactions and maintains electron transport channels to facilitate carbon dioxide photoreduction (CO2PR).

Recently, a research team led by Professor Yang Liangbao from Institute of Health and Medical Technology, Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) proposed an electromagnetic field enhancement mechanism based on the near neighbor electron orbit coupling effect, explaining the mechanism of two-dimensional (2D) layered material Au-2H-TaS2 used for surface enhanced Raman…
