Published Artificial intelligence paves way for new medicines
(via sciencedaily.com) Original source Researchers have developed an AI model that can predict where a drug molecule can be chemically altered.
Published Greener solution powers new method for lithium-ion battery recycling
(via sciencedaily.com) Original source Used lithium-ion batteries from cell phones, laptops and a growing number of electric vehicles are piling up, but options for recycling them remain limited mostly to burning or chemically dissolving shredded batteries. Researchers have improved on approaches that dissolve the battery in a liquid solution in order to reduce the amount of hazardous chemicals used in the process. This simple, efficient and environmentally-friendly solution overcomes the main obstacles presented by previous approaches.
Published Nearly 400,000 new compounds added to open-access materials database
(via sciencedaily.com) Original source New technology often calls for new materials -- and with supercomputers and simulations, researchers don't have to wade through inefficient guesswork to invent them from scratch.
Published Commitments needed to solve aviation's impact on our climate
(via sciencedaily.com) Original source Researchers could find no simple solution to limiting non-CO2 emissions from aircraft.
Published New method verifies carbon capture in concrete
(via sciencedaily.com) Original source Carbon capture is essential to reduce the impact of human carbon dioxide emissions on our climate. Researchers have developed a method to confirm whether carbon in concrete originates from the raw materials, or from carbon in the air which has been trapped when it reacts with the concrete to form the mineral calcium carbonate. By measuring the ratio of certain carbon isotopes in concrete that had been exposed to the air and concrete that hadn't, the team could successfully verify that direct air carbon capture had occurred. This method could be useful for the industrial sector and countries looking to offset their carbon emissions.
Published Separating out signals recorded at the seafloor
(via sciencedaily.com) Original source Research shows that variations in pyrite sulfur isotopes may not represent the global processes that have made them such popular targets of analysis and interpretation. A new microanalysis approach helps to separate out signals that reveal the relative influence of microbes and that of local climate.
Published Chemists use oxygen, copper 'scissors' to make cheaper drug treatments possible
(via sciencedaily.com) Original source Researchers have devised a way to produce chemicals used in medicine and agriculture for a fraction of the usual cost. Using oxygen as a reagent and copper as a catalyst to break organic molecules' carbon-carbon bonds and convert them into amines, which are widely used in pharmaceuticals. Traditional metal catalysis uses expensive metals such as platinum, silver, gold and palladium, but the researchers used oxygen and copper -- an abundant base metal.
Published Hybrid transistors set stage for integration of biology and microelectronics
(via sciencedaily.com) Original source Researchers create transistors combining silicon with biological silk, using common microprocessor manufacturing methods. The silk protein can be easily modified with other chemical and biological molecules to change its properties, leading to circuits that respond to biology and the environment.
Published Neanderthals were the world's first artists, research reveals
(via sciencedaily.com) Original source Recent research has shown that engravings in a cave in La Roche-Cotard (France), which has been sealed for thousands of years, were actually made by Neanderthals. The findings reveal that the Neanderthals were the first humans with an appreciation of art.
Published New method for determining the water content of water-soluble compounds
(via sciencedaily.com) Original source Researchers have developed a new method for the accurate determination of the water content of water-soluble compounds. This plays a significant role in various areas, including determining drug dosages.
Published Effect of aerosol particles on clouds and the climate captured better
(via sciencedaily.com) Original source Global measurements and model calculations show that the complex relationship between the chemistry and climate impact of aerosol particles can be successfully captured by a simple formula.
Published 'Woman the hunter': Studies aim to correct history
(via sciencedaily.com) Original source New research combined both physiological and archaeological evidence to argue that not only did prehistoric women engage in the practice of hunting, but their female anatomy and biology would have made them intrinsically better suited for it.
Published New percussion method to detect pipeline elbow erosion
(via sciencedaily.com) Original source An engineering research team is pioneering a new method, based on percussion, to detect pipeline elbow erosion to prevent economic losses, environmental pollution and other safety issues.
Published Putting an end to plastic separation anxiety
(via sciencedaily.com) Original source Bio-based plastics often end up in recycling streams because they look and feel like conventional plastic, but the contamination of these compostable products makes it much harder to generate functional material out of recycled plastic. Scientists have now developed a biology-driven process to convert these mixtures into a new biodegradable material that can be used to make fresh products. The scientists believe the process could also enable a new field of biomanufacturing wherein valuable chemicals and even medicines are made from microbes feeding off of plastic waste.
Published A deep-sea fish inspired researchers to develop supramolecular light-driven machinery
(via sciencedaily.com) Original source Chemists have developed a bioinspired supramolecular approach to convert photo-switchable molecules from their stable state into metastable one with low-energy red light. Their work enables fast, highly selective, and efficient switching, providing new tools for energy storage, activation of drugs with light, and sensing applications.
Published Shedding light on unique conduction mechanisms in a new type of perovskite oxide
(via sciencedaily.com) Original source The remarkable proton and oxide-ion (dual-ion) conductivities of hexagonal perovskite-related oxide Ba7Nb3.8Mo1.2O20.1 are promising for next-generation electrochemical devices. The unique ion-transport mechanisms they unveiled will hopefully pave the way for better dual-ion conductors, which could play an essential role in tomorrow's clean energy technologies.
Published Pushing the boundaries of eco-friendly chemical production
(via sciencedaily.com) Original source A team of pioneering researchers has made a significant leap forward in the complex world of molecular chemistry. Their focus? Azaarenes, unique molecular puzzle pieces crucial to many everyday products, from eco-friendly agrochemicals to essential medicines. The team developed an innovative way to modify these molecules using light-powered enzymes -- a groundbreaking discovery that holds promise for new industrially relevant chemical reactions and sustainable energy solutions.
