Published Pioneering plasma-catalytic process for CO2 hydrogenation to methanol under ambient conditions
(via sciencedaily.com) Original source A research team reports a pioneering plasma-catalytic process for the hydrogenation of CO2 to methanol at room temperature and atmospheric pressure. This breakthrough addresses the limitations of traditional thermal catalysis, which often requires high temperatures and pressures, resulting in low CO2 conversion and methanol yield.
Published 3D laser printing with bioinks from microalgae
(via sciencedaily.com) Original source Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as 'biofactories' for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigments. An international research team has succeeded for the first time in manufacturing inks for printing complex biocompatible 3D microstructures from the raw materials extracted from the microalgae.
Published Researchers make breakthrough in understanding species abundance
(via sciencedaily.com) Original source The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.
Published New technology uses light to engrave erasable 3D images
(via sciencedaily.com) Original source Researchers invented a technique that uses a specialized light projector and a photosensitive chemical additive to imprint two- and three-dimensional images inside any polymer. The light-based engraving remains in the polymer until heat or light are applied, which erases the image and makes it ready to use again. The technology is intended for any situation where having detailed, precise visual data in a compact and easily customizable format could be critical, such as planning surgeries and developing architectural designs.
Published Finding pearls in the mud: Eco-friendly tungsten recovery from semiconductor waste
(via sciencedaily.com) Original source Semiconductor industry waste is typically seen as a costly disposal problem and an environmental hazard. But what if this waste could be transformed into a valuable resource? In an exciting development, researchers have unveiled an eco-friendly method to extract rare metals from semiconductor waste. This innovative approach not only recovers precious tungsten but also assesses its economic viability, offering a sustainable solution for waste management in the tech industry.
Published Effective new catalyst brings hope for cleaner energy, wastewater treatment, and green chemistry
(via sciencedaily.com) Original source A catalyst that significantly enhances ammonia conversion could improve wastewater treatment, green chemical and hydrogen production.
Published Artificial compound eye to revolutionize robotic vision at lower cost but higher sensitivity
(via sciencedaily.com) Original source A research team has recently developed a novel artificial compound eye system that is not only more cost-effective, but demonstrates a sensitivity at least twice that of existing market products in small areas. The system promises to revolutionize robotic vision, enhance robots' abilities in navigation, perception and decision-making, while promoting commercial application and further development in human-robot collaboration.
Published Detecting climate change using aerosols
(via sciencedaily.com) Original source Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.
Published Increasing clinicians' knowledge about climate change's impact on health and healthcare sustainability
(via sciencedaily.com) Original source A novel educational program for clinicians provided a foundation about climate change and the impact of fossil fuel-related pollution on individual health, and how healthcare systems contribute to carbon pollution and can address these challenges.
Published Alaskan land eroding faster due to climate change
(via sciencedaily.com) Original source A new study shows that frozen land in Alaska is eroding faster than it can be replaced due to climate change.
Published Individuals vary in how air pollution impacts their mood
(via sciencedaily.com) Original source Affective sensitivity to air pollution (ASAP) describes the extent to which affect, or mood, fluctuates in accordance with daily changes in air pollution, which can vary between individuals, according to a new study.
Published Study quantifies air pollution for NYC subway commuters
(via sciencedaily.com) Original source New York City subway commuters who are economically disadvantaged or belong to racial minority groups have the highest exposure to fine particulate matter during their commutes, according to a new study.
Published Work-from-home success might depend on home office setup
(via sciencedaily.com) Original source In a new survey study, Dutch employees who worked from home tended to report higher levels of productivity and less burnout if they were more satisfied with their home office setup. The study also linked more air ventilation in the home office to higher self-reported productivity.
Published Forever chemical pollution can now be tracked
(via sciencedaily.com) Original source Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.
Published X-ray imagery of vibrating diamond opens avenues for quantum sensing
(via sciencedaily.com) Original source Scientists at three research institutions capture the pulsing motion of atoms in diamond, uncovering the relationship between the diamond's strain and the behavior of the quantum information hosted within.
Published Study on planet-warming contrails 'a spanner in the works' for aviation industry
(via sciencedaily.com) Original source Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found.
Published Used concrete transformed into new bricks while trapping CO2
(via sciencedaily.com) Original source Researchers have turned concrete from a demolished school building and carbon dioxide (CO2) from the air into new blocks strong enough to build a house with. The process involved grinding the old concrete into powder, reacting it with CO2 from the air, pressurizing it in layers in a mold and finally heating it to form the new block. Instead of making buildings from new concrete only, this technique could offer a way to recycle old materials while also trapping carbon dioxide in the process. The blocks could theoretically be remade again and again, through the same process.
Published Turning unused signals such as Wi-Fi into energy for electronics
(via sciencedaily.com) Original source We are constantly surrounded by electromagnetic waves such as Wi-Fi. Researchers tested a device to convert this ambient energy into energy for electronic devices.
Published Pesticide contamination is more than apple skin deep
(via sciencedaily.com) Original source Pesticides and herbicides are critical to ensuring food security worldwide, but these substances can present a safety risk to people who unwittingly ingest them. Protecting human health, therefore, demands sensitive analytical methods to identify even trace levels of potentially harmful substances. Now, researchers have developed a high-tech imaging method to detect pesticide contamination at low levels, and its application on fruits reveals that current food safety practices may be insufficient.
Published South Florida estuaries warming faster than Gulf of Mexico, global ocean, USF research shows
(via sciencedaily.com) Original source Estuaries in South Florida have experienced rapid warming over the past two decades, including a record-breaking marine heat wave in 2023, research shows. The findings paint a troubling picture for the marine life that calls Florida home. Possible causes include evaporation, water capacity and residence time (the amount of time water spends in an estuary). No single factor has been identified as dominant.
