    New model for controlling hot molecules reactions, which are relevant to fusion space exploration and planetary science

    10836097-molecule-illustration-over-blue-background-with-copyspace-for-your-text-Stock-Vector

    Hot molecules, which are found in extreme environments such as the edges of fusion reactors, are much more reactive than those used to understand reaction studies at ambient temperature. Detailed knowledge of their reactions is not only relevant to modelling nuclear fusion devices; it is also crucial in simulating the …

    An unexpected finding suggests ways to improve carbon capture materials to clean up fossil fuels

    carbon

    To make “clean” fossil fuel burning a reality, researchers have to pull carbon dioxide out of the exhaust gases that rise from coal or natural gas power plants and store or reuse it. For the capturing feat, researchers are studying special scrubbing liquids that bind and release the gas, but …

    Printing metal in midair

    laser

    “Flat” and “rigid” are terms typically used to describe electronic devices. But the increasing demand for flexible, wearable electronics, sensors, antennas and biomedical devices has led a team at Harvard’s Wyss Institute for Biologically Inspired Engineering and the John A. Paulson School of Engineering and Applied Sciences (SEAS) to innovate …

    Speeding up key oxygen-oxygen bond-formation step in water oxidation

    team

    For years, scientists have been trying to emulate photosynthesis, the process by which plants, algae, and some bacteria harness light from the sun to chemically transform water and carbon dioxide into energy that is stored for later use. An artificial version of photosynthesis could provide a clean, renewable source of …

    Under pressure: New technique could make large, flexible solar panels more feasible

    solar

    A new, high-pressure technique may allow the production of huge sheets of thin-film silicon semiconductors at low temperatures in simple reactors at a fraction of the size and cost of current technology. A paper describing the research by scientists at Penn State University publishes, in the journal Advanced Materials. “We …

    Water molecules break bonds through quantum tunneling

    water

    Water, one of the most common substances on Earth, has served up yet another scientific surprise. In its liquid state, water molecules cling to one another through so-called hydrogen bonding, constantly making and breaking bonds as they jumble about. And within the smallest possible 3D droplet of water, which consists …

    New ‘second skin’ could zap wrinkles, ease eczema

    skin

    There’s new hope for combatting the sags, bags, and wrinkles brought on by time. Today, researchers report that they’ve created a cream that—when rubbed on the skin—forms a transparent, flexible polymer film that restores aging skin’s youthful and elastic properties. Each application of the so-called “second skin” lasts for a day …

    An elastomer that behaves like an artificial muscle

    download

    Animal muscle needs to be strong enough to endure strain; it must also be flexible and elastic; and it is self-healing. Finding a polymer that has all of these properties has proved challenging. However, researchers from Stanford, Nanjing University, UC Riverside, Harvard, and the University of Colorado have reported the …

    Adenine and guanine synthesised using prebiotic pathway

    Prebiotic-synthesis_shutterstock_110038469_300tb

    The formation of the nucleotide bases adenine and guanine under early Earth conditions has been demonstrated by scientists in Germany. Thomas Carell and colleagues at the Ludwig Maximilian University of Munich identified a pathway by which the bases could form from the condensation of formamidopyrimidines with sugars. Formamidopyramidines themselves can …

    Designer rhodium catalyst targets selected C–H bonds

    Catalyst-direct-CH-func_nature17651_Davies-4_300m

    Chemists in the US have designed a catalyst that can activate C–H bonds selectively, without the need for the presence of a more reactive functional group or the use of external directing groups. The finding opens the way to more efficient syntheses of complex organic molecules from simpler precursors. Because …
