Covalent Insertion of a Mn(Salen) Type Complex in Cross‐Linked Protein Crystals: Design of an Enantioselective Artificial Epoxidase

Chemistry – A European Journal, EarlyView.
An Artificial metalloenzyme was designed by a Michael addition between a MnSalen complex and a cysteine residue within NikA crystals. The heterogeneous catalyst was found capable of an enantioselective and stereospecific epoxidation of cis‐β‐methylstyrene in cristallo.

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

Food Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

Vanillin ultraibolya spektrofotometriás meghatározása [PDF]

, 1986
A vanillin lúgos oldatban, az UV és látható színkép határán, jól mérhető abszorpciós maximumot ad, ami azonban a pH-értéktől erősen függ. Az extrahálás során a szorbinsav és a benzoesav is kinyerhető a vanillinnel együtt, azonban lúgos oldatban ezek nem ...

Upcycling Pomegranate Peel Into Functional Yoghurt: Chemical Profile, Antioxidant Capacity, and Anti–Staphylococcus aureus Activity

Food Safety and Health, EarlyView.
Pomegranate peel extract enhanced the nutritional, physicochemical, and microbiological qualities of yoghurt. It is a rich source of polyphenolic compounds that eliminates Staphylococcus aureus in yoghurt at 0.1% and 0.3% concentrations without altering its pH value. ABSTRACT The use of natural additives, particularly pomegranate peel extract (PPE), to
