Study reveals the mechanisms causing an equatorward shift in the lifetime maximum intensity locations of North Atlantic tropical cyclones Tropical cyclones (TCs) are extremely destructive weather events imperiling coastal communities. Long-term climatological changes can significantly alter the intensity and course of TCs, possibly making them more dangerous. A key factor…

Scientists explore current research on antibiotic resistance genes in bioaerosols with a focus on the sources, detection strategies, and future research direction While there are many studies that discuss antibiotic resistance genes (ARG) in soil and water environments, there is currently very little research that focuses on ARG in aerial…

Scientists elucidate the toxic effects of a common aquatic pollutant, the PAH Benzo[α]pyrene (BaP) on bay scallops Polycyclic aromatic hydrocarbons (PAHs) are one of the most common pollutants released into the sea. They negatively affect aquatic ecosystem, but their impact on marine animals has not been sufficiently explored. …

The study shows that controlling the mixing gradient of the component materials in functionally graded materials can improve mechanical properties (FGMs) are high-performance materials with expected applications in aerospace, automobiles, defense, and medicine. These materials are usually employed in conditions of extreme temperature and pressure, therefore making it important for…

New study investigates how water hardness affects zinc accumulation and oxidative stress in goldfish Heavy metals like zinc — which are present in industrial effluents when they are released into water bodies — can accumulate in fishes, causing toxicity. Korean scientists studied the changes in goldfish who were exposed to…

Scientists develop an efficient synthesis route to produce a novel co-doped anode material for rechargeable seawater batteries Despite the many potential applications of seawater batteries (SWBs), the limited performance of available materials has hindered their commercialization. To tackle this issue, scientists from Korea Maritime and Ocean University have developed a…

Researchers identify liquefied petroleum gas as a low-cost and eco-friendly alternative to marine propulsion fuels Regulatory agencies monitoring the activities of ships are increasingly adopting eco-friendly measures to combat the environmental damage caused by propulsion fuels. Although liquefied petroleum gas (LPG) is a potential eco-friendly alternative, its viability as a…

Scientists develop new anti-corrosion coating to increase the economic life and durability of steel machinery in an environment-friendly manner Although steel is widely used in industry, its low corrosion resistance limits the life of the equipment and hinders certain applications such as shipping and implementation of marine technologies. …

New technological advancement uses an electric field to achieve efficient and low-cost ammonia removal from wastewater Given its environmental toxicity, ammonia is removed during wastewater purification and then used for fertilizers or fuel. However, this process is very energy and chemical intensive. …
