Les esters en cosmétologie : généralités et fonctionnalités
Esters belong to the large family of lipids where they are famous for their role as emollients. After briefly talking about their synthesis, we will study their functionality and particulary their different uses as « émollient, émulsifiant, et co ...

Predicting Ruthenium Catalysed Hydrogenation of Esters using Machine Learning
Catalytic hydrogenation of esters is a sustainable approach for the production of fine chemicals, and pharmaceutical drugs. However, the efficiency and cost of catalysts are often the bottlenecks in the commercialization of such technologies.

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Iridium-catalyzed asymmetric transfer hydrogenation of quinolines with Hantzsch esters
The iridium-catalyzed enantioselective transfer hydrogenation of quinolines with Hantzsch esters was developed with up to 88%, ee using [Ir(COD)Cl](2)/(S)-SegPhos/I-2 as a catalyst.

Sulfur fluoride exchange (SuFEx) is a powerful click platform, yet water‐compatible multifunctional linchpins remain elusive. Here, we report decagram‐scalable diazonium linchpins that enable rapid Pd‐catalyzed diversification and direct, catalyst‐free on‐DNA ligation in aqueous media.

Tandem organic solar cells with optimized ternary acceptor engineering achieved a power conversion efficiency of 15.53% and enabled a high‐voltage mini‐module (Voc 6.11 V). Integration into a bias‐free PV‐EC system further demonstrated efficient solar‐to‐ammonia (STA) conversion (97% Faradaic Efficiency, 4± 2% STA efficiency), highlighting scalable ...

Determination of chlorinated fatty acids using SPE, XSD and GC/MS [PDF]
Chlorinated fatty acids (ClFAs) account for a considerable portion of the extractable, organically bound chlorine (EOCl) in aquatic animals. Because of analytical difficulties little is as of yet known about their behaviour in organisms.
