Published Hybrid catalyst produces critical fertilizer and cleans wastewater
(via sciencedaily.com) Original source Synthetically produced fertilizer urea supports half of global population. Using pure metals, researchers develop hybrid catalyst with capacity to convert waste nitrogen and carbon dioxide to urea. The process could denitrify wastewater and runoff while creating a new revenue stream for water treatment facilities.
Published Researchers make a significant step towards reliably processing quantum information
(via sciencedaily.com) Using laser light, researchers have developed the most robust method currently known to control individual qubits made of the chemical element barium. The ability to reliably control a qubit is an important achievement for realizing future functional quantum computers.
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 Valleytronics: Innovative way to store and process information up to room temperature
(via sciencedaily.com) Researchers have found a way to maintain valley polarization at room temperature using novel materials and techniques.
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 Machine learning contributes to better quantum error correction
(via sciencedaily.com) Researchers have used machine learning to perform error correction for quantum computers -- a crucial step for making these devices practical -- using an autonomous correction system that despite being approximate, can efficiently determine how best to make the necessary corrections.
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 Atomically-precise quantum antidots via vacancy self-assembly
(via sciencedaily.com) Scientists demonstrated a conceptual breakthrough by fabricating atomically precise quantum antidots using self-assembled single vacancies in a two-dimensional transition metal dichalcogenide.
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 Deriving the fundamental limit of heat current in quantum mechanical many-particle systems
(via sciencedaily.com) Researchers have mathematically derived the fundamental limit of heat current flowing into a quantum system comprising numerous quantum mechanical particles in relation to the particle count. Further, they established a clearer understanding of how the heat current rises with increasing particle count, shedding light on the performance constraints of potential future quantum thermal devices.
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 Better cybersecurity with new material
(via sciencedaily.com) Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
