An 'exceptionally stable' single-atom catalyst

20 hours 15 minutes ago
Scientists at Tokyo Institute of Technology (Tokyo Tech) have shown that single platinum atoms trapped in C12A7 crystals act as a stable and effective catalyst for the hydrogenation of nitroarenes, an essential process in the production of many kinds of fine chemicals. Their approach could become a versatile route for developing other single-atom catalysts for wide-ranging industrial applications.

Having an eye for colors: Printable light sensors

22 hours 50 minutes ago
Cameras, light barriers, and movement sensors have one thing in common: They work with light sensors that are already found in many applications. In future, these sensors might also play an important role in telecommunications, as they enable data transmission via light. At the InnovationLab in Heidelberg, scientists of Karlsruhe Institute of Technology (KIT) succeeded in making decisive progress: Printable light sensors that can see colors. The results are now reported in Advanced Materials.

Programmable droplet manipulation by a magnetic-actuation robot

23 hours 34 minutes ago
Droplet manipulation in materials science can contribute to water collection, medical diagnostics and drug delivery techniques. While structure-based liquid operations are widely used in nature and in bioinspired artificial materials, laboratory strategies depend on fixed structures for unidirectional water movement. In a new study on Science Advances, An Li and a research team in the Institute of Chemistry and the University of Chinese Academy of Sciences in China proposed to develop a magnetic-actuated robot. The construct had adjustable structures to distribute forces of resistance and determine droplet behavior. The robot could transport, split, release and rotate droplets for universal applications in various fields and rough environments. The new findings offer an efficient strategy for automated droplet manipulation.

Porous liquid holds bigger molecules

23 hours 52 minutes ago
An international team of chemists has developed a method for creating an ionic-liquid, porous, tetrahedral coordination cage that holds larger molecules than other porous liquids. In their paper published in the journal Nature Chemistry, the group describes their technique and the types of molecules their liquids were able to hold.

Sneaking up on tiny crystals with electron diffraction

3 days 21 hours ago
Understanding the structure of proteins, the building blocks of life, is essential to obtain insight into their biological function. Due to their minute size and extreme fragility, these structures are enormously difficult to determine. Acquiring data of sufficient resolution requires immense doses of high energy X-ray radiation, which unfortunately irrevocably damages the proteins principally being investigated.

Shaping the rings of molecules

Macrocycles are molecules made of large rings of atoms. Despite being relatively big and flexible, the molecules don't always stay "floppy"—they can actually lock themselves into specific shapes and geometries.

Essential oil components can be tested as drug candidates

3 days 23 hours ago
A research team at the VIB-KU Leuven Center for Microbiology and the KU Leuven Department of Biology showed that, contrary to generally held belief, most components of essential oils could meet the criteria set for drug candidates. Essential oil components are the constituents of essential oils, which are complex mixtures of plant metabolites obtained by dry or steam distillation, or by citrus peel pressing.

A bioplastic that protects against UV radiation

3 days 23 hours ago
Researchers at the University of Oulu's Research Unit of Sustainable Chemistry have developed a new synthetic bioplastic that, unlike traditional carbon-based plastics or other bioplastics, provides protection from the sun's ultraviolet radiation.

Scientists use light to convert fatty acids into alkanes

4 days 22 hours ago
Researchers led by Prof. Wang Feng at the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences have reported that photocatalytic decarboxylation is an efficient alternate pathway for converting biomass-derived fatty acids into alkanes under mild conditions of ambient temperature and pressure. This finding was published in Nature Catalysis on Feb. 19.
