Second- and third-row transition metal complexes are widely employed in photocatalysis, whereas earth-abundant first-row metals have found only limited use because of the prohibitively fast decay their excited states. We report an unforeseen reactivity mode for productive photocatalysis that uses cobalt polypyridyl as photocatalysts by exploiting Marcus inverted region behavior couples increases excited-state energies with increased lifetimes. These (III) can engage bimolecular virtue strong...
Increasing interest in sustainable chemistry coupled with the quest to explore new reactivity has spurred research on first-row transition metal complexes for potential applications a variety of settings. One more active areas is photoredox catalysis, where synthetically tunable nature their electronic structures provides rich palette options tailoring desired chemical transformation. Understanding mechanism excited-state critical informed development next-generation catalysts, which turn...
We introduce a technique called ambient electrospray deposition Raman spectroscopy (AESD RS) for rapid and sensitive surface-enhanced scattering (SERS) based detection of analytes using miniature spectrometer. Using electrospray, soft landing preformed silver nanoparticles (AgNPs) was performed 30-40 seconds different concentrations deposited on conducting glass slides. AESD RS, SERS signals were collected within 4-6 minutes, including sample preparation. Transmission electron microscopy...
Experimental validation of the predicted melt phase behavior A/B mixed brush on planar substrate is presented using poly(methyl methacrylate) (A)/ polystyrene (B) (PMMA/PS) with equal number chains as an example. Well-defined brushes are synthesized a single component inimer coating to achieve high grafting density (0.9 chains/nm2), uniformity sites, and predictable chain length. The copolymer nitroxide-mediated polymerization (NMP) inimer, atom transfer radical (ATRP) styrene, glycidyl...
Herein, subtle changes in the molecular orientations of different thiols upon interaction with soft-landed silver nanoparticles (AgNPs) have been probed using technique called ambient electrospray deposition Raman spectroscopy (AESD RS). The method collects real-time surface-enhanced scattering (SERS) spectra analytes as Raman-active AgNPs were electrodeposited on a substrate. We used p-mercaptobenzoic acid (p-MBA), benzenethiol (BT), and cyclohexanethiol (CHT) proof-of-concept ligands for...
Objective: This study was performed to explore the perceptions of treatment utilization patterns and risk overdose both opioid users their peer educators in Kolkata, India. Methods: used a qualitative approach for data collection between September December 2023. In-depth interviews (IDIs) 20 from two authorized substitution therapy (OST) centers (10 registered clients) respective field practice areas unregistered Kolkata were conducted. Key informant (KIIs) six also Semi-structured...
