Rapid transformation of sulfinate salts into sulfonates promoted by a hypervalent iodine(III) reagent

open access: yesBeilstein Journal of Organic Chemistry, 2018
An alternative method for forming sulfonates through hypervalent iodine(III) reagent-mediated oxidation of sodium sulfinates has been developed. This transformation involves trapping reactive sulfonium species using alcohols. With additional optimization

Synthesis of Poly(Itaconate)s With High Monomer Conversion Applying Emulsion Polymerization

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1284-1296, 15 March 2025.
Itaconic acid and its derivatives are a promising and bio‐based substitute for oil‐based polymers such as acrylates. In this study, the optimization of polymerization of itaconic acid esters is described by applying emulsion polymerization leading to high reaction conversions and low residual monomer contents. ABSTRACT Itaconic acid and its derivatives

Comparative Evaluation of Single and Combined Adsorption and Peroxone Processes for Taste and Odour Control in Reservoir Water

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT Taste and odour compounds (T&O), particularly 2‐methylisoborneol (2‐MIB) and geosmin, pose persistent challenges in drinking water treatment, as conventional methods often achieve limited removal. This study provides a comparative evaluation of five treatment strategies: activated carbon (AC) adsorption, sulfonic acid‐modified activated carbon

Liver X Receptor α (LXRα) Regulates 5β‐Reductase (AKR1D1) Expression in Avian Embryos: Implications for Yolk Steroid Metabolism

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 5, Page 456-461, June 2026.
ABSTRACT Steroid‐mediated maternal effects are well‐studied as a source of phenotypic variation. In bird eggs, the yolk contains various steroids that can influence embryonic development. However, one complicating factor in understanding how yolk steroids affect development is that the embryo metabolizes yolk steroids to regulate exposure.
