Industrial Chemicals Delay Recovery of the Ozone Layer | Newswise
[ad_1] BYLINE: Manuel Martin Newswise — Although ozone-depleting chemicals such as carbon tetrachloride (CCl₄) or certain chlorofluorocarbons (CFCs) are no longer used in refrigerators and foams, they continue to serve as feedstocks in industrial processes for the production of modern refrigerants and plastics. Until now, these so-called feedstock chemicals have flown under the radar of […]
Sandia Researchers Develop Rapid PFAS Detector | Newswise
[ad_1] Newswise — ALBUQUERQUE, N.M. —When Sandia scientists Ryan Davis and Nathan Bays set out to find a better way to absorb and degrade PFAS in water sources, they kept running into the same issue: Detecting the chemicals in samples took too long. So, they came up with their own solution. They’ve developed a faster, […]
Tiny flow chips, faster clean catalysis | Newswise
[ad_1] Catalytic treatment of industrial pollutants has long faced a practical bottleneck. Noble metal nanoparticles are highly active, but they often tend to aggregate, reducing the number of active usable reaction sites. Traditional methods for producing polymer-supported catalysts can also be slow, multistep, and dependent on toxic reagents, surfactants, or poorly controlled batch conditions. Meanwhile, […]
How Antibiotic-Degrading Bacteria Shield Microbial Communities From Collapse | Newswise
[ad_1] Newswise — By comparing natural microbial adaptation with targeted bioaugmentation using an antibiotic-degrading strain, the study reveals how biodegradation capacity fundamentally reshapes microbial succession, stability, and resilience under sustained antibiotic exposure. Environmental risk assessments often judge antibiotics solely by concentration and intrinsic toxicity, assuming uniform microbial responses. However, microbial communities actively shape contaminant fate, […]
Stopping Algae Blooms with Bacteria-Busting Buoys | Newswise
[ad_1] Newswise — Algae blooms make a pond’s surface shine in mesmerizing green hues. But if the microorganisms responsible are cyanobacteria, they can also release toxins that harm humans and wildlife alike. So, a team reporting in ACS ES&T Water has designed a “set it and forget it” system for distributing algaecide using specialized buoys tethered at […]
Sulfuric Acid Method Improves Accuracy of Nitrogen Isotope Tracking for Atmospheric Ammonia | Newswise
[ad_1] Newswise — By comparing sulfuric and boric acid absorption systems, they found sulfuric acid delivers higher recovery rates and reduces isotope fractionation, even at low concentrations. Field applications successfully distinguished emissions from cropland, livestock, orchards, and vegetables, improving the accuracy of ammonia source identification. NH₃ is the most important alkaline gas in the atmosphere […]
Why GNSS-R Soil Moisture Retrieval Has Relied on Reference Products—and How a Physics-Based Approach Is Changing That | Newswise
[ad_1] Newswise — For decades, global soil moisture monitoring from space has depended on reference datasets. Satellite observations, while indispensable, are rarely used alone; instead, their retrieval algorithms are typically calibrated or constrained using external soil moisture products derived from other satellites, models, or reanalysis systems. This practice has helped stabilize retrievals, but it has […]
Can Greener Clothes Flatten Carbon Emissions? New Pathways for China’s Textile Industry | Newswise
[ad_1] Newswise — As global demand for clothing continues to rise, the textile and apparel industry has become a significant contributor to climate change. In China, the world’s largest textile producer and exporter, rapid urbanization, income growth, and shifting consumption patterns have driven a surge in apparel demand. Traditional studies often focus on factory-level energy […]
Two WHOI Scientists Honored with Lifetime Achievement Award for Advances in Oil-Spill Forensics | Newswise
[ad_1] Robert Nelson and Christopher Reddy recognized for pioneering use of GCxGC to track and understand marine pollution Newswise — Woods Hole, Mass. (February 20, 2026) — Two chemical oceanographers from the Woods Hole Oceanographic Institution (WHOI) are being awarded the 2026 Lifetime Scientific Achievement Award by the International Symposium on Comprehensive Multidimensional Chromatography. Robert […]
Produce Hydrogen and Oxygen Simultaneously From a Single Atom! Achieve Carbon Neutrality with an ‘All-in-One’ Single-Atom Water Electrolysis Catalyst | Newswise
[ad_1] Newswise — Green hydrogen production technology, which utilizes renewable energy to produce eco-friendly hydrogen without carbon emissions, is gaining attention as a core technology for addressing global warming. Green hydrogen is produced through electrolysis, a process that separates hydrogen and oxygen by applying electrical energy to water, requiring low-cost, high-efficiency, high-performance catalysts. The Korea […]
