Breaking the limit of chemical compounds

Since the end of the 19th century, transition metal carbonyls have been an important and familiar class of compound in coordination chemistry and organometallic chemistry. In these materials, carbon monoxide molecules (CO) ...

New STM technique points way to new and purer pharmaceuticals

A research project led by chemists at the University of Warwick first used ultrahigh resolution scanning tunnelling microscopy to see the exact location of atoms and bonds within a molecule, and then employed these incredibly ...

New study looks to biological enzymes as source of hydrogen fuel

Research from the University of Illinois and the University of California, Davis has chemists one step closer to recreating nature's most efficient machinery for generating hydrogen gas. This new development may help clear ...

Researchers obtain an important chemical compound

Since the discovery of the first homoleptic metal carbonyl complex Ni(CO)4 more than 130 years ago, scientists try to obtain further such compounds formed from a carbon monoxide molecule and a metal that are important for ...

Chemical bond versus electromagnetic waves

Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the ...

Physicists build fractal shape out of electrons

In physics, it is well-known that electrons behave very differently in three dimensions, two dimensions or one dimension. These behaviours give rise to different possibilities for technological applications and electronic ...

Researchers investigate complex molecular structures

The job of hemoglobin seems to be quite simple: It transports oxygen molecules through the bloodstream. But this only works so well because the hemoglobin molecule is extremely complex. The same applies to chlorophyll, which ...

NASA-led study solves a methane puzzle

A new NASA-led study has solved a puzzle involving the recent rise in atmospheric methane, a potent greenhouse gas, with a new calculation of emissions from global fires. The new study resolves what looked like irreconcilable ...

Hot vibrating gases under the electron spotlight

Natural gas is used in refineries as the basis for products like acetylene. The efficiency of gaseous reactions depends on the dynamics of the molecules—their rotation, vibration and translation (directional movement). ...
