Published New study highlights feasibility and optimization of ammonia-based power generation for carbon neutrality
(via sciencedaily.com) A research team has evaluated the feasibility of ammonia-based power generation through techno-economic and carbon footprint analyses.
Published Bees struggle to find flowers because of air pollution
(via sciencedaily.com) Original source A new study has found that air pollution is preventing pollinators finding flowers because it degrades the scent.
Published Beaver activity in the Arctic increases emission of methane greenhouse gas
(via sciencedaily.com) Original source The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane -- a greenhouse gas -- into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays.
Published New bio-based glues form adhesive bonds that grow stronger in water
(via sciencedaily.com) Patent-pending adhesive formulations developed from fully sustainable, bio-based components establish bonds that grow stronger when underwater or exposed to wet conditions.
Published Bursting air bubbles may play a key role in how glacier ice melts
(via sciencedaily.com) Original source New research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice.
Published Capturing carbon in savannas: New research examines role of grasses for controlling climate change
(via sciencedaily.com) New research shows that, in addition to trees, humble grasses also play an essential role in capturing carbon.
Published Extending the playing field for organosulfurs: a new way to synthesize sulfinate esters
(via sciencedaily.com) Sulfinate esters, a type of organosulfur compounds, are typically synthesized using thiols. However, these substances are difficult to work with due to their unpleasant smell and oxidizability in air. Now, a research team has found a way to produce sulfinate esters through the direct oxidation of thioesters, which are easily accessible and stable. Their findings will help expand the field of organosulfur chemistry and hopefully lead to new applications in pharmaceuticals.
Published Chemists devise a method for C-H activation of alcohols
(via sciencedaily.com) Chemists have extended a powerful molecule-building method -- called C-H activation -- to the broad class of chemicals known as alcohols.
Published Researchers develop highly efficient and stable photoelectrode for water splitting using organic semiconductors
(via sciencedaily.com) A recent study has unveiled a significant breakthrough in photoelectrode development.
Published Switching from harmful to helpful fungi
(via sciencedaily.com) Original source Mold and diseases caused by fungi can greatly impact the shelf life of fruit and vegetables. However, some fungi benefit their hosts by aiding plant survival. Colletotrichum tofieldiae (Ct) is a root mold which typically supports continued plant development even when the plant is starved of phosphorus, an important nutrient for photosynthesis and growth. Researchers studied a unique pathogenic strain of the fungi, called Ct3, which conversely inhibits plant growth.
Published Electrifying heavy-duty vehicles could reduce environmental inequalities
(via sciencedaily.com) If the region surrounding Chicago -- North America's largest freight hub -- shifted just 30% of its current on-road heavy-duty vehicles to electric versions, it would substantially reduce pollution and save hundreds of lives per year, with the benefits largely concentrated in disadvantaged communities, according to a new study. The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.
Published New ribozyme can make RNA molecules accessible for click chemistry in living cells
(via sciencedaily.com) Important progress for RNA research: A team has discovered a new ribozyme that can label RNA molecules in living cells.
Published Bit by bit, microplastics from tires are polluting our waterways
(via sciencedaily.com) Urban stormwater particles from tire wear were the most prevalent microplastic a new study has found. The study showed that in stormwater runoff during rain approximately 19 out of every 20 microplastics collected were tire wear particles with anywhere from 2 to 59 particles per liter of water. Tire rubber contains up to 2500 chemicals with the contaminants that leach from tires considered more toxic to bacteria and microalgae than other plastic polymers.
Published Novel titanium dioxide catalyst support for electrocatalytic carbon dioxide reduction
(via sciencedaily.com) Carbon dioxide can be electrocatalytically reduced to useful resources using conventional catalysts such as gold or lead supported on conductive carbon. However, the high pH environment near electrodes often degrades the catalyst support, rendering them ineffective. Now, researchers have developed novel in-liquid plasma-treated titanium dioxide electrode decorated with silver nanoparticles as an alternate catalyst support, facilitating enhanced conversion of carbon dioxide to useful products, such as syngas, a clean alternative to fossil fuels.
Published Efficient and mild: Recycling of used lithium-ion batteries
(via sciencedaily.com) Lithium-ion batteries (LIBs) provide our portable devices like tablets and mobiles -- and increasingly also vehicles -- with power. As the share of volatile renewable energy needing electricity storage increases, more and more LIBs are needed, lithium prices rise, resources dwindle, and the amount of depleted batteries that contain toxic substances increases. Researchers introduce a novel approach for the recovery of lithium from used LIBs.
Published 3D-printed 'living material' could clean up contaminated water
(via sciencedaily.com) A 'living material,' made of a natural polymer combined with genetically engineered bacteria, could offer a sustainable and eco-friendly solution to clean pollutants from water. Researchers developed their living material using a seaweed-based polymer and bacteria that have been programmed to produce an enzyme that transforms various organic pollutants into harmless compounds. In tests, heir material decontaminated water solutions tainted with a pollutant from textile manufacturing: indigo carmine, a blue dye that is used to color denim.
Published Blowing snow contributes to Arctic warming
(via sciencedaily.com) Original source Atmospheric scientists have discovered abundant fine sea salt aerosol production from wind-blown snow in the central Arctic, increasing seasonal surface warming.
Published New research explains 'Atlantification' of the Arctic Ocean
(via sciencedaily.com) Original source New research by an international team of scientists explains what's behind a stalled trend in Arctic Ocean sea ice loss since 2007. The findings indicate that stronger declines in sea ice will occur when an atmospheric feature known as the Arctic dipole reverses itself in its recurring cycle. The many environmental responses to the Arctic dipole are described in a recent article. This analysis helps explain how North Atlantic water influences Arctic Ocean climate. Scientists call it Atlantification.
Published Toxic molds, fossil fuels, antibiotics linked to chemical intolerance
(via sciencedaily.com) Original source Toxic mold left behind by Hurricane Idalia could initiate chemical intolerance (CI) in some individuals, experts said. In a survey of thousands of Americans, mold exposure was the most frequently cited initiating cause of CI, according to a recently published study.
Published Striking gold with molecular mystery solution for potential clean energy
(via sciencedaily.com) Hydrogen spillover is exactly what it sounds like. Small metal nanoparticles anchored on a thermally stable oxide, like silica, comprise a major class of catalysts, which are substances used to accelerate chemical reactions without being consumed themselves. The catalytic reaction usually occurs on the reactive -- and expensive -- metal, but on some catalysts, hydrogen atom-like equivalents literally spill from the metal to the oxide. These hydrogen-on-oxide species are called 'hydrogen spillover.'
