Harnessing Toluene Solvent as a Reactant: Regioselective Benzyl Radical Addition to Multi‐π 1,5‐Enynes in a Copper‐Catalyzed Cascade to Indenes

Chemistry – A European Journal, EarlyView.
A copper‐catalyzed three‐component radical cascade of 1,5‐enynes with toluene and benzoic acids enables regioselective benzyl radical addition to multi‐Π systems, efficiently delivering polysubstituted indenes from an abundant solvent feedstock. ABSTRACT C─H activation of toluene generates a benzyl radical that undergoes C─C coupling, converting an ...

Investigation of Benzoic Acid Adsorption on to ODTMA-Bentonite by Response Surface Optimization

Adsorption Science & Technology, 2002
The adsorption of benzoic acid on to a modified bentonite (ODTMA-bentonite) was studied. ODTMA-bentonite was synthesized by the incorporation of a quaternary ammonium surfactant (octadecyltrimethylammonium bromide) on to Ç ankiri sodium bentonite (Ç Na-B)

Operando Magic Angle Spinning Solid‐State NMR Spectroscopy of Methanol Photoreforming Over Titania‐Coated Silica Monoliths

Chemistry – A European Journal, EarlyView.
Photoreforming of methanol is followed in real time by solid‐state Magic Angle Spinning NMR. The transparent sapphire sample holder is irradiated by four LEDs at 11.5 kHz MAS. Efficient light penetration into the sample volume is ensured by silica monoliths with a network of macropores, coated with TiO2, and enhancing light penetration by a factor of ...

Selective Modification of the Product Profile of Biocatalytic Hydrolyzed PET via Product‐Specific Medium Engineering

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.

Phenolic Profiles, Antioxidant Properties and Predicted Glycaemic Index of Bread Sweetened With Date Syrup in Comparison With Granulated Sugar

Food Chemistry International, EarlyView.
Date syrup are used as sweetener in bread. Bread with date syrup had superior phenolic composition, better antioxidant properties and carbohydrate hydrolysing enzymes while bread with granulated sugar had higher predicted glyceamic index. The study concluded that date syrup could be the next though‐out ingredient for dual purpose in bread. ABSTRACT The

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Amino‐functionalized lanthanide metal‐organic frameworks encapsulating boron‐doped graphene quantum dots: A paper based fluorescent sensor to visual detection of salicylic acid

FlexMat, EarlyView.
Abstract Salicylic acid (SA), a widely distributed environmental pollutant, requires accurate detection for effective water quality monitoring and ecological protection. In this work, we developed a highly sensitive fluorescent sensor by encapsulating boron‐doped graphene quantum dots (B‐GQDs) within amino‐functionalized lanthanum‐based metal‐organic ...
