Published Eco-efficient cement could pave the way to a greener future
(via sciencedaily.com) Scientists develop process to remove toxic heavy metals from coal fly ash, making for greener, stronger concrete.
Published Team uses natural catalysts to develop low-cost way of producing green hydrogen
(via sciencedaily.com) Researchers have developed a practical way to produce green hydrogen using sustainable catalysts and say their work is a major step towards production simpler, more affordable and more scalable.
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 What should we call evolution driven by genetic engineering? Genetic welding, says researcher
(via sciencedaily.com) With CRISPR-Cas9 technology, humans can now rapidly change the evolutionary course of animals or plants by inserting genes that can easily spread through entire populations. An evolutionary geneticist proposes that we call this evolutionary meddling 'genetic welding.' He argues that we must scientifically and ethically scrutinize the potential consequences of genetic welding before we put it into practice.
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 Advanced electrode to help remediation of stubborn new 'forever chemicals'
(via sciencedaily.com) As new environmental regulations are rolling out to mitigate the industry-retired long-chain chemicals known as PFAS in drinking water, there are concerns regarding a new breed of 'forever chemicals' called short-chain PFAS. Research is now helping shift the focus to include mitigation of the chemicals -- which researchers say are just as persistent as, more mobile and harder to remove from the environment than their long-chain counterparts.
Published Nanophysics: The right twist
(via sciencedaily.com) Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.
Published Rare beetle, rediscovered after 55 years, named in honor of Jerry Brown
(via sciencedaily.com) While sampling for insects on former California Gov. Jerry Brown's ranch, a University of California, Berkeley, entomologist collected a rare species of beetle that had never been named or described -- and which, according to records, had not been observed by scientists in over 55 years. The new species will be named Bembidion brownorum, in honor of Jerry Brown and his wife, Anne Brown.
Published What do the elements sound like?
(via sciencedaily.com) In chemistry, we have He, Fe and Ca -- but what about do, re and mi? Using a technique called data sonification, a recent college graduate has converted the visible light given off by each of the elements into soundwaves. The notes produced for each element are unique, complex mixtures and are the first step toward an interactive, musical periodic table.
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.
Published Photosynthesis: Varying roads lead to the reaction center
(via sciencedaily.com) Chemists use high-precision quantum chemistry to study key elements of super-efficient energy transfer in an important element of photosynthesis.
Published Scientists discover easy way to make atomically-thin metal layers for new technology
(via sciencedaily.com) A new breakthrough shows how to make MXenes far more quickly and easily, with fewer toxic byproducts.
Published Habitat will dictate whether ground beetles win or lose against climate change
(via sciencedaily.com) The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.
Published Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability
(via sciencedaily.com) Large amounts of plastic waste are incinerated or deposited in landfills. This degrades the environment and depletes valuable resources. In this light, recycling plastics such as polymers is promising. However, recycling diminishes their quality. Recently, researchers have proposed a 'closed-loop' recycling process based on polymer microparticles. It produces fully recyclable polymer films with high mechanical stability and fracture energy, which they retain upon recycling.
Published AI finds the first stars were not alone
(via sciencedaily.com) Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.
Published Towards reducing biodiversity loss in fragmented habitats
(via sciencedaily.com) By combining lab experiments and mathematical modelling, researchers have found a way to predict the movement of species that could guide conservation efforts to reconnect fragmented habitats.
Published Sea otters killed by unusual parasite strain
(via sciencedaily.com) An unusually severe form of toxoplasmosis killed four sea otters and could pose a threat to other marine wildlife and humans, finds a new study.
Published Photosynthesis 'hack' could lead to new ways of generating renewable energy
(via sciencedaily.com) Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.
Published Semiconductor lattice marries electrons and magnetic moments
(via sciencedaily.com) A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.
Published New mosquito species reported in Florida
(via sciencedaily.com) A mosquito known only by its scientific name, Culex lactator, is the latest to establish in the Sunshine State, according to a new study.
