Published New nanoparticles can perform gene-editing in the lungs
(via sciencedaily.com) Original source A new type of nanoparticle can be administered to the lungs, where it can deliver messenger RNA encoding useful proteins. Researchers hope to use them to develop new treatments for cystic fibrosis and other lung diseases.
Published AI predicts enzyme function better than leading tools
(via sciencedaily.com) Original source A new artificial intelligence tool can predict the functions of enzymes based on their amino acid sequences, even when the enzymes are unstudied or poorly understood. Researchers said the AI tool, dubbed CLEAN, outperforms the leading state-of-the-art tools in accuracy, reliability and sensitivity. Better understanding of enzymes and their functions would be a boon for research in genomics, chemistry, industrial materials, medicine, pharmaceuticals and more.
Published Mimicking biological enzymes may be key to hydrogen fuel production
(via sciencedaily.com) An ancient biological enzyme known as nickel-iron hydrogenase may play a key role in producing hydrogen for a renewables-based energy economy, researchers said. Careful study of the enzyme has led chemists to design a synthetic molecule that mimics the hydrogen gas-producing chemical reaction performed by the enzyme.
Published Chemists design new molecule, with oxygen as the star of the show
(via sciencedaily.com) Chemists have achieved a new feat in the realm of chemical design and synthesis: They've helped create the first example of a synthetic molecule, with an asymmetric oxygen atom as its centerpiece, that remains stable and nonreactive -- despite this type of molecule's tendency in nature to be touchy and short-lived. What makes this feat unique is that the new molecule is chiral, which means it has a non-superimposable mirror image.
Published Revolutionary battery technology to boost EV range 10-fold or more
(via sciencedaily.com) A team develops layering-charged, polymer-based stable high-capacity anode material.
Published Modern origami method creates glass shapes by folding
(via sciencedaily.com) Original source The ancient art of origami is well known for transforming sheets of paper and other foldable materials into complex 3D shapes. But now, chemical engineers have extended the centuries-old practice to produce intricate shapes made of glass or other hard materials. Their thoroughly modern method, which can be combined with 3D printing, could have applications ranging from sculpture to catalysis and beyond.
Published Biomolecules: Trying nanometer measurement for size
(via sciencedaily.com) Original source As part of a comparative international study, researchers have successfully tested and validated a method of investigating dynamic protein structures.
Published Probe where the protons go to develop better fuel cells
(via sciencedaily.com) Original source Researchers have uncovered the chemical inner-workings of an electrolyte they developed for a new generation of solid oxide fuel cells. To uncover the location of the proton-introduction reaction, the team studied extensively the hydration reaction of their scandium-substituted barium zirconate perovskite through a combination of synchrotron radiation analysis, large-scale simulations, machine learning, and thermogravimetric analysis. The new data has the potential to accelerate the development of more efficient fuel cells.
Published Team designs molecule to disrupt SARS-CoV-2 infection
(via sciencedaily.com) A team of scientists designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.
Published Looking from different perspectives! Proper electronic structure of near-infrared absorbing functional dyes discovered
(via sciencedaily.com) A research group has discovered that near-infrared absorbing dyes, which had previously been considered to have closed-shell electronic structures, have an intermediate electronic structure, between closed- and open-shell structures. They also found that as the wavelength of near-infrared light that can be absorbed becomes longer the contribution of open-shell forms increases within the dye. These newly discovered characteristics are expected to be utilized to develop new near-infrared absorbing dyes that can absorb longer wavelength near-infrared light.
