Coulometric and Amperometric Studies [PDF]

open access: yes, 1954
The coulometric titration of thiosulfate with iodine has been investigated at different hydrogen ion concentrations. The applicability of this titration to the determination of oxidizing agents has been demonstrated by determining microgram quantities of

Antimicrobial and Photocatalytic Activities of Selenium Nanoparticles Synthesized from Elaeagnus indica Leaf Extract

open access: yes, 2023
Selenium nanoparticles (Se NPs) have recently received much interest due to their low toxicity, high bioavailability, and wide applications. This study synthesized Se NPs using selenious acid as a starting material and leaf extract from Elaeagnus indica ...

Studies in Organo-Selenium Compounds: Part I. Determination of Se

open access: yes, 1961
Selenium in some organo-selenium compounds has been determined colorimetrically by conversion to selenious acid and hence to a selenium sol stabilised with chlorpromazine hydrochloride.

Selenosugar, selenopolysaccharide, and putative selenoflavonoid in plants

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 3, May 2024.
Abstract Selenium (Se) is a naturally occurring essential micronutrient that is required for human health. Selenium supports cellular antioxidant defense and possesses bioeffects such as anti‐inflammation, anti‐cancer, anti‐diabetic, and cardiovascular and liver protective effects arising from Se‐enhanced cellular antioxidant activity.

Cutting schedule and species composition to improve energy‐to‐protein ratios in alfalfa‐based mixtures

open access: yesAgronomy Journal, Volume 116, Issue 1, Page 276-288, January/February 2024.
Abstract Energy‐to‐protein ratios have been suggested as a potential forage attribute related to nitrogen (N) use efficiency in dairy cows but how these ratios vary with the cutting management of alfalfa‐based mixtures is poorly known. Our objective was to determine the effect of cutting schedules of alfalfa‐based mixtures and their species composition

Thiol Reduction of Arsenite and Selenite: DFT Modeling of the Pathways to an As–Se Bond

open access: yes, 2016
The reactivity of arsenite and selenite with biological thiols plays an important role in the toxicity of these elements. However, toxic effects are eliminated when the species are coadministered, due to the antagonistic relationship between selenium and
