(UV2550, Shimadzu, Japan).The concentrations of Fe(II)and Cr(VI) in solution were detected also by the UV–Vis spec-trophotometer.The color reaction agents for Fe(II)and Cr(VI)were 1,10-phenanthroline monohydrate and diphenylcarbazide, respec-tively.The operating wavelength was 510 nm for...
In this case, therefore, the promoting effect arises mainly from the change in the oxidation state of the loaded material. In the chemical sensitization, the promoting effect is due to the spill-over induced by metal particles, that facilitates the reaction of the inflammable gases with oxygen ...
1. If the parts are stocked in a high temperature and humidity environment, problems such as reduced solderability caused by oxidation of terminal electrodes and deterioration of taping/packaging materials may take place. For this reason, components should be used within 6 months from the time ...

Smad5 (small mothers against decapentaplegic 5) protein is a receptor-regulated member of the Smad family proteins, mainly participating in the bone morphogenetic protein (BMP) signaling pathway in its phosphorylated form. This article will provide a det
Although addition of pyrolyzed organic materials (biochars) to soil generally results in increased growth and physiological performance of plants, neutral
The use of bio-stimulants in agriculture has emerged as a promising strategy to improve crop growth and yield. One type of bio-stimulant that has gained attention is microalgae extracts, which are known for their high metabolic activity, bioactive compounds, and ability to enhance plant growth ...
Furthermore, the simultaneous presence of a large number of surface species on the catalyst surface often poses a great challenge for the unambiguous determination of the relevant species in the reaction mechanism. In contrast, enzymes possess catalyti-cally active centers with precisely defined ...
Oxidative stress is a common pathological state in a high-risk population for osteoporosis. • Reactive oxygen species accumulation and antioxidant enzyme activity reduction contributes to oxidative damage in osteoporosis. • Proinflammatory factors and HIF-1α provided a supplement of oxidative stress-...
