Uptake of selenium by aquatic organisms [PDF]
Limnology and Oceanography, 1973 The Se content of aquatic organisms was lowest in aquatic plants, varying from 0.02 to 0.14 ppm (dry wt). Plankton samples contained from 1.1 to 2.4 ppm, fishes cultured in ponds 0.5 to 0.9 ppm, and fishes from natural environments 1.0 to 2.9 ppm.The phytoplankter, Scenedesmus dimorphus, actively concentrated 75Se‐selenomethionine, but neither actively

Selenium-catalyzed organic transformations
iScienceSelenium-catalyzed organic transformations have recently emerged as a promising frontier in modern organic synthesis. The unique combination of high polarizability, redox tunability, and σ-hole-driven Lewis acidity enables selenium to act as powerful non-covalent activators in both covalent and non-covalent catalytic cycles.

Advanced Functional Materials, EarlyView.A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a
