Modeling a better catalyst for PIBSAs
Polyisobutenyl succinic anhydrides (PIBSAs) are important for the auto industry because of their wide use in lubricant and fuel formulations. Their synthesis, however, requires high temperatures and, therefore, higher cost......»»
Paper offers a mathematical approach to modeling a random walker moving across a random landscape
Tiny particles like pollen grains move constantly, pushed and pulled by environmental forces. To study this motion, physicists use a "random walk" model—a system in which every step is determined by a random process. Random walks are useful for stu.....»»

Unlocking the heat in mosquito modeling: Exploring disease transmission under climate change
Thermal adaptation is the ability of organisms to adjust their life history traits as the temperature changes. In the case of mosquitoes, these traits can determine their risk of transmitting mosquito-borne diseases and how this risk might change in.....»»
Catalyst combines vanadium-based components and nitrogen-doped biomass carbon for pollutant removal
Polychlorinated dibenzo-p-dioxins and dibenzofurans are dangerous pollutants due to their carcinogenicity and persistence in the environment. Traditional catalytic oxidation methods for their removal face challenges like high cost and inefficiency at.....»»
Step aside, internal tides: Supercomputer modeling improves satellite altimetry precision
Waves don't take place just on the ocean's surface. Underneath the crests and troughs that we can see from above are internal tides, which form when tidal flows collide with seamounts, continental slopes, and ridges on the seafloor......»»
Cooler, wetter parts of Pacific Northwest likely to see more fires, new simulations predict
Forests in the coolest, wettest parts of the western Pacific Northwest are likely to see the biggest increases in burn probability, fire size and number of blazes as the climate continues to get warmer and drier, according to new modeling led by an O.....»»
The modeling and simulation of self-organized intracellular twisters in the Drosophila oocyte
Cytoplasmic streaming is the large-scale motion of cytoplasm (i.e., gelatinous liquid inside cells) inside a living cell. This flow, known to regulate various intracellular processes, can vary greatly between different cell types at different stages.....»»
Advanced artificial photosynthesis catalyst uses CO₂ more efficiently to create biodegradable plastics
Amid growing global concern over climate change and plastic pollution, researchers at Osaka Metropolitan University are making great strides in the sustainable production of fumaric acid—a component of biodegradable plastics such as polybutylene su.....»»
