Summary: Recently, CsPbX3 (X= Cl, Br, I) nanocrystals (NCs) have shown promise for optoelectronic applications, particularly in bioimaging, due to their superior photophysical properties. However, their poor stability in aqueous media poses a challenge. To address this, we developed a fast and reproducible synthesis method that coats CsPbBr3 NCs with long-chained organic ligands/polymers. Among them, polyvinylpyrrolidone (PVP) encapsulated NCs exhibit highly luminescent properties and improved stability when incorporated with n-isopropyl acrylamide (NIPAM). These polymer-coated NCs demonstrate better water stability, smaller particle size, uniform distribution, higher structural stability, and increased dispersivity, making them suitable as fluorescent probes for live cell imaging. The dosage of Pb-ions in the polymer-coated NCs is calculated to be below 5 μg/mL, enabling safe live cell imaging. This work provides valuable insights for expanding the application of these NCs in bioimaging with higher sensitivity.

Summary: Nitrogen-fluorine codoped graphene quantum dots (N, F-GQDs) were synthesized through a one-pot hydrothermal method using glucose and ammonium fluoride (AF). The composition of nitrogen and fluorine with GQDs by AF was optimized to approach the highest light absorption edge in UV- visible spectroscopy and receive upconversion properties in photoluminescence (PL) analysis. The best cell with N, F-GQD0.07/TiO2/ FTO photoanode improved the efficiency, open circuit voltage, and short circuit current density, from 0.07 to 0.51, 370 to 699 mV, and 0.3 to 1.2 mA/cm2, respectively, compared to the cell fabricated by the blank TiO2/FTO photoanode.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
