Visible‐Light‐Promoted, (Photo)catalyst‐Free Synthesis of 3‐Sulfonyl‐Azaspiro[4.5]trienones via Arylazo Sulfones

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A set of 3‐sulfonyl‐azaspiro[4.5]trienones have been obtained via a metal‐ and photocatalyst‐free visible‐light‐driven dearomative strategy. The protocol exploits arylazo sulfones, which act simultaneously as the light absorber and sulfonyl‐radical source, enabling ipso‐spirocyclization of differently substituted N‐aryl propiolamides.

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

open access: yesFood Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

A New Method for Mixed Matrix Composite Membranes Preparation Using Direct Spray‐Coating Technique

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The development of membranes has evolved over the last years as an effective CO2 separation technology to fight the environmental impact of post‐combustion processes. In this regard, the upgrade of conventional polymers has been approached through different strategies to overcome their permeance‐selectivity trade‐off.

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

open access: yesGeological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...
