Published Scientists unveil cutting-edge ruthenium catalyst for new reaction discovery and optimization
(via sciencedaily.com) Original source Researchers have achieved a groundbreaking advancement in catalyst technology.
Published Using pulp and paper waste to scrub carbon from emissions
(via sciencedaily.com) Original source Researchers have come up with an innovative approach to improve the energy efficiency of carbon conversion, using waste material from pulp and paper production. The technique they've pioneered not only reduces the energy required to convert carbon into useful products, but also reduces overall waste in the environment.
Published How scientists are accelerating chemistry discoveries with automation
(via sciencedaily.com) Original source Scientists have developed an automated workflow that could accelerate the discovery of new pharmaceutical drugs and other useful products. The new automated approach could analyze chemical reactions in real time and identify new chemical-reaction products much faster than current laboratory methods.
Published A simple, inexpensive way to make carbon atoms bind together
(via sciencedaily.com) Original source The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon -- a carbon atom bonded to four other carbon atoms. But now, scientists have uncovered a potential cost-effective way to produce these tricky motifs.
Published Chemical reactions can scramble quantum information as well as black holes
(via sciencedaily.com) Original source A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.
Published Rapid, simultaneous detection of multiple bacteria achieved with handheld sensor
(via sciencedaily.com) Original source A team has developed a method for simultaneous detection of multiple disease-causing bacterial species within one hour using a handheld device.
Published 'Tug of war' tactic enhances chemical separations for critical materials
(via sciencedaily.com) Original source Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.
Published Developing a vaccine for the 'zombie drug' xylazine
(via sciencedaily.com) Original source Chemical biologists design an early 'proof-of-concept' vaccine that could lead to the first effective treatment of xylazine overdose in people.
Published Unleashing disordered rocksalt oxides as cathodes for rechargeable magnesium batteries
(via sciencedaily.com) Original source Researchers have made a groundbreaking advancement in battery technology, developing a novel cathode material for rechargeable magnesium batteries that enables efficient charging and discharging even at low temperatures.
Published Plastic-free vegan leather that dyes itself grown from bacteria
(via sciencedaily.com) Original source Researchers have genetically engineered bacteria to grow animal- and plastic-free leather that dyes itself.
Published Water-based paints: Less stinky, but some still contain potentially hazardous chemicals
(via sciencedaily.com) Original source Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as 'greener' and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs). But, according to new research, some of these paints do contain compounds that are considered VOCs, along with other chemicals of emerging concern.
Published Chemistry researchers modify solar technology to produce a less harmful greenhouse gas
(via sciencedaily.com) Original source Researchers are using semiconductors to harvest and convert the sun's energy into high-energy compounds that have the potential to produce environmentally-friendly fuels.
Published Engineers 'symphonize' cleaner ammonia production
(via sciencedaily.com) Original source Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the high temperatures and energy needed to manufacture it. But by improving on a well-known electrochemical reaction and orchestrating a 'symphony' of lithium, nitrogen and hydrogen atoms, engineers have developed a new ammonia production process that meets several green targets.
Published Physics-based predictive tool will speed up battery and superconductor research
(via sciencedaily.com) Original source Researchers have developed physics-based guidelines that will benefit host-guest intercalated materials research. By using only two guest properties and eight host-derived descriptors, they correctly predicted the intercalation energies and stabilities of many host-guest systems. This work is an important advance that will minimize the extensive trial-and-error laboratory work that otherwise slows down research and development in battery and superconductor technologies.
Published New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects
(via sciencedaily.com) Original source Analysing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health, say scientists.
Published Study unlocks the power of visible light for sustainable chemistry
(via sciencedaily.com) Original source A breakthrough in sustainable molecular transformations has been announced. Chemists have developed an important way to harness the power of visible light to drive chemical processes with greater efficiencies, offering a greener alternative to traditional methods.
Published Revolutionary biomimetic olfactory chips to enable advanced gas sensing and odor detection
(via sciencedaily.com) Original source A research team has addressed the long-standing challenge of creating artificial olfactory sensors with arrays of diverse high-performance gas sensors. Their newly developed biomimetic olfactory chips (BOC) are able to integrate nanotube sensor arrays on nanoporous substrates with up to 10,000 individually addressable gas sensors per chip, a configuration that is similar to how olfaction works for humans and other animals.
Published More efficient TVs, screens and lighting
(via sciencedaily.com) Original source New multidisciplinary research could lead to more efficient televisions, computer screens and lighting.
Published A solar cell you can bend and soak in water
(via sciencedaily.com) Original source Researchers have developed an organic photovoltaic film that is both waterproof and flexible, allowing a solar cell to be put onto clothes and still function correctly after being rained on or even washed.
Published Micro-Lisa! Making a mark with novel nano-scale laser writing
(via sciencedaily.com) Original source High-power lasers are often used to modify polymer surfaces to make high-tech biomedical products, electronics and data storage components. Now researchers have discovered a light-responsive, inexpensive sulfur-derived polymer is receptive to low power, visible light lasers -- promising a more affordable and safer production method in nanotech, chemical science and patterning surfaces in biological applications.
