Summary: This study investigates the influence of solvent steric profile on the formation of linear or helical chains using a diphenyl-derivatized tetraoxolene ligand (H(2)Ph(2)dhbq). The helical chain exhibits temperature-dependent valence tautomerism, while the linear chain is more amenable to oxidative doping, leading to a significant increase in electrical conductivity.

Summary: The synthesis of sandwich-shaped multinuclear silver complexes with planar penta- and tetranuclear wheel-shaped silver units and a central anion is reported. By altering the central anion or adding/removing a silver atom, the size of the silver wheels can be adjusted. NMR mechanistic studies reveal the formation sequence of the silver complexes and provide insights into the dynamics of the self-assembly process.

Summary: We report on di- and trinuclear palladium sandwich complexes of cross-pi-conjugated fulvenes. Structural and theoretical analysis demonstrated that the fulvene sandwich framework possesses a metal-metal bonded moiety, with strong donation and back-donation observed in the dinuclear and trinuclear bonds, respectively. The trinuclear fulvene sandwich complex exhibits a unique reversible extrusion of a Pd atom from inside to outside the sandwich framework.

Summary: This study presents a density-based 3D minimum compliance topology optimization method for sandwich structures with anisotropic shells. Through a two-step filtering approach, a constant thickness shell is enforced at the interface of a base structure. Homogenous effective properties of a cellular material are assigned to the base structure while the shell is treated as a constant stiffness laminate with anisotropic properties. The local shell normal vectors and material orientations in the shell's tangent plane are approximated based on the density gradient and the fabrication process of the structure.

Summary: The reaction of 4-[(CH2O)(2)CH]C6H4Br with n-BuLi, followed by the insertion of the chalcogen (S or Se) and in situ reaction with n-BuBr, has led to the formation of (n-Bu){4-[(CH2O)(2)CH]C6H4}E [E = Se (1), S (2)]. Deprotection of the formyl groups in 1 and 2 has resulted in (n-Bu)[4-(CHO)C6H4]E [E = Se (3), S (4)], which were further used for the preparation of (n-Bu)[4-{2-C6H5-(4H)-oxazol-5-one}C6H4]E [E = Se (5), S (6)].

Summary: N atoms were successfully doped into the lattice of ZnO nanoparticles using ZIF-8 as a self-sacrificial template through a thermal treatment process with the assistant of urea. The obtained N-ZnO exhibited competitive ethanol-sensing performance. It was found that N-doping facilitated the formation of oxygen vacancy and the larger specific surface area resulting from size reduction during the urea-assisted pyrolysis process contributed to the improved ethanol-sensing performance.

Summary: Metal-organic frameworks (MOFs) have been widely applied in catalysis and sensing due to their large specific surface area, control-lable structure, and high concentration of active metal sites. However, their potential applications in photocatalysis and luminescence sensors face challenges such as charge recombination, low solar energy utilization, low quantum yield, and limited charge transfer. Recent studies have shown that the introduction of carbon dots (CDs) can greatly enhance the functions of MOFs. This paper reviews the synthesis methods of CD-MOF composites and their potential applications in photocatalysis and sensing, with emphasis on representative examples and key features.

Summary: Waste PET plastics were utilized to create Ag3PO4/UiO-66-NH2@PET (PAU-X) for the adsorption and light-responsive desorption of SMX. PAU-X can capture SMX in the absence of light and release it under visible light. The breaking of the Ag-N bond between Ag3PO4 and SMX is the main mechanism for the desorption process.

Summary: Fe-based MOF S-BUC-21(Fe) exhibited superior catalytic activity in peroxymonosulfate (PMS) activation for the removal of atrazine (ATZ), achieving complete degradation within 20 min. The reactive species generated through the Fe2+/Fe3+ cycle, including SO4??-, ??OH, ??O2???, and 1O2, played major roles in the ATZ degradation process. Additionally, the quantification and generation pathways of 1O2 were revealed, and S-BUC-21(Fe) showed outstanding stability and reusability.

Summary: A series of WO3/MIL-100(Fe) (WxMy) composites were synthesized via the mild solvent evaporation method and used as a catalyst for the degradation of sulfamethoxazole (SMX) through a sulfate radical-advanced oxidation process (SR-AOP). The W4M1 composite showed excellent catalytic activity, with 100% SMX degradation efficiency within 15 minutes under visible light. The efficient transfer of photo-generated electrons from WO3 to MIL-100(Fe) contributed to the outstanding SR-AOP catalysis activity.

Summary: MIL-88A(Fe)/BOHP (MxBy) heterojunctions were fabricated as catalysts to activate hydrogen peroxide (H2O2) through visible light illumination. The catalytic degradation efficiency of enrofloxacin (ENR) in the M3B7/Vis/H2O2 system reached almost 100% with good mineralization ability. The formation of interfacial Fe-O-P chemical bonds between MIL-88A(Fe) and BOHP effectively reduced the charge transfer energy barrier and migration distance, leading to efficient separation of photo-generated carriers and improved activation efficiency of H2O2.

Summary: This study investigated the effects of ZIF-8 NPs on zebrafish, and found that exposure to 90 mg/L concentration significantly reduced locomotor activity and increased freezing states in both genders, with males being more sensitive. ZIF-8 NPs exposure also decreased oxidative stress enzyme activities in the zebrafish brain. These findings emphasize the need for further assessment of potential risks of MOF nanoparticles to aquatic species and the environment.

Summary: A three-dimensional cobalt-MOF was synthesized for activating peroxymonosulfate (PMS) to degrade ATZ. The material exhibited excellent sulfate radical-advanced oxidation processes (SR-AOPs) activation performance, degrading 100% ATZ within 30 minutes through the recycling of Co2+/Co3+. The effects of pH, PMS dosage, catalyst dosage, co-existing anions, and natural organic matters (NOMs) on ATZ degradation were investigated in detail, and the reusability, stability, and universality of the catalyst were tested under optimal conditions. It is worth noting that long-term continuous ATZ degradation was achieved using a self-developed device.
