La(FeCuMnMgTi)O High-Entropy Oxide Nanoparticles as Highly Efficient Catalysts for Solvent-Free Aerobic Oxidation of Benzyl Alcohol.

In this work, a solid-state method for the synthesis of perovskite La(FeCuMnMgTi)O high-entropy oxide (HEO) nanoparticles is detailed. Additionally, the high performance of these nanoparticles as catalysts in the aerobic and solvent-free oxidation of benzyl alcohol is demonstrated. The structural features of HEO nanoparticles are studied by X-ray diffraction and high-resolution transmission electron microscopy.

[Comparative efficacy of a combination of undenatured type II collagen, Boswellic acids, methylsulfonylmethane, vitamins C and D and a combination of chondroitin sulfate and glucosamine hydrochloride in the treatment of primary osteoarthritis of the knee joint].

Aim: To evaluate the efficacy of Artneo (AN) in comparison with a combination of glucosamine hydrochloride and chondroitin sulfate (GC) in patients with osteoarthritis (OA) of the knee joint (KJ).

Materials And Methods: 70 patients with stages I-III of primary knee OA were randomized into 2 groups. Participants in the 1st (=35) took AN 1 caps/day, in the 2nd (=35) GC according to the standard regimen.

High-Entropy La(FeCuMnMgTi)O Nanoparticles as Heterogeneous Catalyst for CO Electroreduction Reaction.

In this work, La(FeCuMnMgTi)O HEO nanoparticles with a perovskite-type structure are synthesized and used in the electrocatalytic CO reduction reaction (CORR). The catalyst demonstrates high performance as an electrocatalyst for the CORR, with a Faradaic efficiency (FE) of 92.5% at a current density of 21.

Thermal, morphology and bacterial analysis of pH-responsive sodium carboxyl methylcellulose/ fumaric acid/ acrylamide nanocomposite hydrogels: Synthesis and characterization.

In this present investigation, sodium carboxymethyl cellulose grafted with Fumaric acid/Acrylamide (CMC/FA/AAm=CFA) hydrogel and their silver nanocomposite hydrogels (CFA-Ag , x = 5, 10 and 20) were developed by simple, cost effective and ecofriendly greener method. Mint leaf extract was used as an efficient natural reducing agent due to presence of active and antioxidant potential of polyphenol and flavonoid components. Swelling equilibrium of CFA hydrogel showed S% 3000 both in pH medium and distilled water.

Preparation, phase stability, and magnetization behavior of high entropy hexaferrites.

The polycrystalline SrFeO samples deeply substituted up to at.67% by Al, Ga, In, Co, and Cr cations with a high configurational mixing entropy were prepared by solid-phase synthesis. Phase purity and unit cell parameters were obtained from XRD and analyzed versus the average ionic radius of the iron sublattice.
