(via sciencedaily.com) Original source Researchers to get a better look at how peroxides on the surface of copper oxide promote the oxidation of hydrogen but inhibit the oxidation of carbon monoxide, allowing them to steer oxidation reactions.
Published Toward tunable molecular switches from organic compounds
(via sciencedaily.com) Original source Newly synthesized organic molecules can be tuned to emit different colors depending on their molecular structures in crystal form.
Published New atomic-scale understanding of catalysis could unlock massive energy savings
(via sciencedaily.com) Original source In an advance they consider a breakthrough in computational chemistry research, chemical engineers have developed a model of how catalytic reactions work at the atomic scale. This understanding could allow engineers and chemists to develop more efficient catalysts and tune industrial processes -- potentially with enormous energy savings, given that 90% of the products we encounter in our lives are produced, at least partially, via catalysis.
Published Long-forgotten equation provides new tool for converting carbon dioxide
(via sciencedaily.com) Original source To manage atmospheric carbon dioxide and convert the gas into a useful product, scientists have dusted off an archaic -- now 120 years old -- electrochemical equation.
Published DMI allows magnon-magnon coupling in hybrid perovskites
(via sciencedaily.com) Original source An international group of researchers has created a mixed magnon state in an organic hybrid perovskite material by utilizing the Dzyaloshinskii--Moriya-Interaction (DMI). The resulting material has potential for processing and storing quantum computing information.
Published Scientists use computational modeling to design 'ultrastable' materials
(via sciencedaily.com) Original source Researchers developed a computational approach to predict which metal-organic framework (MOF) structures will be the most stable, and therefore the best candidates for applications such as capturing greenhouse gases.

(via sciencedaily.com) Original source New transistor technology boosts the body's electrochemical signals by 1,000 times, enabling diagnostic and disease-monitoring implants.
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 Researchers use 21st century methods to record 2,000 years of ancient graffiti in Egypt
(via sciencedaily.com) Researchers are learning more about ancient graffiti -- and their intriguing comparisons to modern graffiti -- as they produce a state-of-the-art 3D recording of the Temple of Isis in Philae, Egypt.
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 Ancient DNA reveals Asian ancestry introduced to East Africa in early modern times
(via sciencedaily.com) The largest-yet analysis of ancient DNA in Africa, which includes the first ancient DNA recovered from members of the medieval Swahili civilization, has now broken the stalemate about the extent to which people from outside Africa contributed to Swahili culture and ancestry.
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.
