A Reusable Chip for Particulate Matter Sensing | Newswise
[ad_1] Newswise — Fine airborne particles are especially challenging to monitor because particle size affects both how long they remain suspended in air and how deeply they can penetrate into the respiratory system. PM2.5 is of particular concern because of its association with adverse health effects. Existing techniques, including beta-ray absorption, gravimetric methods, and light-scattering […]
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 […]
Accessing Dynamic Electrochemical Interfaces
[ad_1] The Science Newswise — Electrodes’ surfaces drive reactions that are critical to energy conversion. In batteries, electrodes accept and release electrons. This process charges and discharges the battery. However, scientists know little about the chemistry of these surfaces during this process. Techniques that are sensitive to these surfaces require a vacuum or conditions that are […]
How a Plant Hormone Slows Apple Ripening by Rewriting Protein Fate | Newswise
[ad_1] Newswise — Ethylene is a central hormone controlling ripening in climacteric fruits such as apple, tomato, and banana, coordinating color change, softening, and flavor development. While manipulating ethylene production has long been a target for improving fruit storage, most approaches focus on enzyme activity or gene expression rather than upstream regulatory mechanisms. Salicylic acid […]
These Teabags Aren’t for Making Tea — They Remove Arsenic | Newswise
[ad_1] Newswise — Arsenic contamination in drinking water is a global issue, with over 200 million people estimated to be at risk. While water treatment plants remove the metal, the problem persists in low-resource areas or undertreated well water. So, researchers reporting in ACS Omega have designed a simple solution: an arsenic-removing teabag. The system is inexpensive, costing around 7 cents to clean a liter of water, and highly effective, removing over 90% of the arsenic ions present. “Clean drinking water should not depend on access to expensive […]
Harrisburg University Students Design Oyster-Based Aquaculture System for Space Exploration | Newswise
[ad_1] Newswise — HARRISBURG, PA – The future of space exploration is currently hampered by humankind’s ability to sustainably provide nutrition, environmental control, and life support for long-duration human spaceflight. NASA’s Biology & Physical Sciences Division outlined these gaps in a 2024 report entitled, A New Era in Space: Ensuring the Future of Biological and Physical Sciences Research: A […]
A Painless, High-Precision Imaging Platform Brings Lymphatic Function Into View | Newswise
[ad_1] Newswise — The lymphatic system plays a critical role in pathological conditions such as lymphedema and chronic inflammation to tumor metastasis, venous insufficiency, and impaired wound healing, making accurate evaluation of its structure and function increasingly important. Yet current imaging tools—including lymphoscintigraphy, magnetic resonance lymphangiography , indocyanine green fluorescence imaging, and conventional methylene blue […]
Recycling Plants’ Plastic-Cleaning Process May Pose Water Contamination Risks | Newswise
[ad_1] Newswise — AMES, Iowa – Potentially harmful chemicals can contaminate untreated water used in recycling plants to clean plastics before they’re processed into new products, according to a new study by an Iowa State University research group. Researchers from Iowa State’s Polymer and Food Protection Consortium tested common industrial plastic-washing practices and found that […]
Ancient Tectonic Processes the Key to Locating Rare Minerals | Newswise
[ad_1] Newswise — New research from Adelaide University has revealed that geological processes dating back billions of years are critical to locating the rare earth elements needed for modern technologies and the global clean energy transition. Published today in Science Advances, the study shows a strong global link between ancient subduction zones – where tectonic […]
New ORNL Electrolyte Lets the Ions Flow
[ad_1] BYLINE: Greg Cunningham Newswise — Researchers at the Department of Energy’s Oak Ridge National Laboratory have uncovered a path to design superionic polymer electrolytes for solid-state batteries and other energy applications that could help ensure a future of abundant and reliable energy for the United States. The scientists demonstrated that by carefully controlling the […]
