Missing electrons reveal the true face of a new copper-based catalyst
New research has resulted in a reactive copper-nitrene catalyst that pries apart carbon-hydrogen (C-H) bonds and transforms them into carbon-nitrogen (C-N) bonds, which are a crucial building block for chemical synthesis, especially in pharmaceutical manufacturing.

New technique enables implantation of individual ions into crystals with an accuracy of 35 nanometers.
Read moreConverting absorbed photons into twice as many excitons
A group of researchers found that when light was exposed to the surface of a tetracene alkanethiol-modified gold nanocluster, which they developed themselves, twice as many excitons could be converted compared to the number of photons absorbed by the tetracene molecules. These findings are expected to contribute to areas such as solar energy conversion, electronics, life sciences, and medical care in the future.

Researchers have come up with a new, safe way to clean up oil spills using compounds equally useful as common household cleaning products.
Read moreHook-on drugs: New delivery strategy for K-Ras disruption
Scientists have succeeded in designing a compound to hook onto the pocket of the enzyme FTase and GGTase I, thereby inhibiting K-Ras. Scientists have worked to concoct an effective drug to target K-Ras proteins which cause cancer when they mutate. It is difficult to infiltrate K-Ras due to a lack of interactive pockets, so a strategy was devised to attack the necessary enzyme in the lipid modification of K-Ras.

Separating pure ethylene from ethane is a difficult and costly process, but one that new research is poised to streamline. The technique would avoid liquefaction and distillation by designing a material that only binds ethylene molecules, thus separating them from ethane.
Read moreNo clear link between local food and cancer risk in glassworks areas
There is no clear link between cancer incidence and locally produced food from an area with a history of glass manufacture with contaminated soil, according to a new study. A high consumption of certain local foods seems to be linked to an increased risk of certain cancers, but this probably reflects that the exposure to contaminants was higher in the past.
Read moreNew framework for nanoantenna light absorption
Harnessing light's energy into nanoscale volumes requires novel engineering approaches to overcome a fundamental barrier known as the 'diffraction limit.' However, researchers have breached this barrier by developing nanoantennas that pack the energy captured from light sources.
