Summary: CsPbX3 (X=Cl, Br, I) nanocrystals were successfully synthesized in fluorophosphate glasses for the first time, with controlled formation through adjustment of cooling rate and heat treatment conditions. The X-ray diffraction data and optical measurements confirmed the formation of 4-11 nm sized CsPbX3 nanocrystals, with the presence of two narrow bands in the luminescence spectra due to the introduction of two anions complicating the preparation process. The CsPb(Cl, Br)3 quantum dots exhibited high intensity photoluminescence with a quantum yield of 45-50% and narrow emission band.

Summary: This study presents a method to enhance the photocurrent density of bismuth vanadate (BiVO4) photoanodes using a nitrogen-doped cobalt-iron oxide (N-CFO) cocatalyst layer. The N-CFO/BVO photoanode shows higher photocurrent density compared to pure BVO and CFO/BVO with oxygen vacancies. Mechanism studies reveal that nitrogen dopants improve the electrical conductivity and reaction activity of cobalt-iron oxide. This work provides a novel strategy for designing efficient and cheap cocatalysts for photoanodes using Prussian blue analogues.

Summary: Revealing the impact of structural disorder in lead halide perovskites on photocarrier dynamics, this study found that in the disordered beta phase, photoinduced carriers recombine almost twice slower and diffuse 20% faster compared to the ordered gamma phase. However, within the same phase, carrier diffusion and recombination show no significant difference for different A-site mobilities with similar PbX6 orientations. This confirms the effective influence of lattice disorder on the carrier dynamics, highlighting the importance of the Pb-X sublattice over A-site cations for future lead halide perovskite design and applications.

Summary: The design of an efficient OER catalyst is crucial for water splitting. Metal-organic frameworks (MOFs) with their versatile structures and adjustable functions have emerged as promising electrocatalysts. In this study, 2D FexCo1-x-MOF1/NF with an extended ligand, BPDC, was fabricated on nickel foam using a solvothermal method. Compared to MOF2 synthesized with BDC, MOF1 exhibited excellent performance. Among MOF1, Fe0.5Co0.5-MOF1/NF showed outstanding activity with a low overpotential (217 mV) and a small Tafel slope (31.16 mV Dec(-1)) at 10 mA cm(-2), while maintaining good performance at high current densities. The catalyst also displayed remarkable durability in alkaline solution and simulated seawater. The synergetic effect between Fe and Co, as well as the increased number of active sites exposed, played a crucial role in enhancing the OER activity. This work provides an effective strategy for the rational design of inexpensive MOFs as electrocatalysts.

Summary: This study resolves the issue of carrier recombination on the dual surfaces of the m-BiVO4 component in water oxidation by constructing an m-BiVO4/carbon nitride (C3N4) Z-scheme heterostructure based on the m-BiVO4/reduced graphene oxide (rGO) Mott-Schottky heterostructure. The rGO effectively accumulates photogenerated electrons from m-BiVO4 and facilitates their diffusion through a highly conductive carbon network. The Z-scheme electron transfer at the heterointerface of m-BiVO4/C3N4 leads to spatial separation of electron-hole pairs and maintains strong redox potentials, resulting in significantly improved O-2 yield and the generation of center dot OH and center dot O-2(-) radicals.

Summary: In this study, a chemical mechanism-based surface-enhanced Raman spectroscopy (SERS) substrate with remarkable enhancement and sensitivity was developed using a band structure engineered W18O49/g-C3N4 heterostructure. The Raman enhancement behavior of the substrate was attributed to efficient charge transfer, energy band matching resonance, and improved photo-induced charge transfer (PICT) efficiency. Additionally, a flexible SERS substrate based on this heterostructure was constructed and successfully used for the detection of prohibited pharmaceutical residues on fish skin.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
