Published A solar hydrogen system that co-generates heat and oxygen
(via sciencedaily.com) Original source Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size.
Published Luminous molecules
(via sciencedaily.com) Original source Twisted molecules play an important role in the development of organic light-emitting diodes. A team of chemists has managed to create these compounds with exactly the three-dimensional structure that they wanted. In so doing, they are smoothing the path for new and better light sources.
Published Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists
(via sciencedaily.com) Original source Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.
Published Scientists use peroxide to peer into metal oxide reactions
(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.
Published Discovery of crucial clue to accelerate development of carbon-neutral porous materials
(via sciencedaily.com) Original source A recent study has provided a library of those various molecular clusters for future metal building blocks of MOFs, and suggested practical synthetic strategies.
Published Major storage capacity in water-based batteries
(via sciencedaily.com) Original source Chemical engineers have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes.
Published Strong ultralight material could aid energy storage, carbon capture
(via sciencedaily.com) Original source Materials scientists showed that fine-tuning interlayer interactions in a class of 2D polymers can determine the materials' loss or retention of desirable mechanical properties in multilayer or bulk form.
Published Plastic transistor amplifies biochemical sensing signal
(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 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.
