Summary: A three-dimensional geometry-like plasmon Ag/AgNbO3/BiVO4 (Ag/ANO/BVO) Z-type heterojunction photocatalyst was synthesized using electrostatic self-assembly and photo-deposition method. Levofloxacin hydrochloride (LEF) was used as the target degradation object to evaluate photocatalytic activity. The 3-Ag/ANO/BVO composite exhibited the highest photocatalytic properties compared to other synthesized catalysts. The enhanced photocatalytic activity can be attributed to the formation of Z-type heterojunction and the broadened visible light absorption range by localized surface plasmon resonance (LSPR) in the 3-Ag/ANO/BVO composite.

Summary: SiC nano-powders with Al2O3-Y2O3- MgO-CaO additive (NITE-SiC) were used as joining materials for low-temperature joining of SiC ceramics, by controlling the thickness of the interlayers (-10 μm and -60 μm). Residual pores were observed in the -60 μm interlayer after joining at 1650 degrees C, with a shear strength of 39.3 +/- 5.5 MPa. Decreasing the interlayer thickness to -10 μm resulted in no cracks or porosity at the interface region, with a shear strength of 69.5 +/- 8.9 MPa and fracture originating from the matrix. The results showed that using NITE-SiC with Al2O3-Y2O3- MgO-CaO additive as the joining layer and reducing the thickness of the interlayer could lower the joining temperature and significantly improve the mechanical strength of joints.

Summary: The effect of ultrafine fly ash (UFA) and fly ash (FA) on the physical properties and micro-structure of magnesium potassium phosphate cement (MKPC) was studied. UFA addition did not affect the hydration peak of MKPC formation but led to increased reaction duration and potential formation of secondary reaction products. The addition of a UFA:FA blend delayed the hydration and setting time of MKPC. MgKPO4 center dot 6H2O was the main crystalline phase observed, but Mg2KH(PO4)2 center dot 15H2O was also observed at low replacement levels in the UFA-only system. UFA and UFA:FA acted as fillers and diluents. The optimized formulation with 40 wt % fly ash (10 wt % UFA and 30 wt % FA) achieved the highest compressive strength and fluidity, producing a dense microstructure.

Summary: In this study, a data-driven search method for two-dimensional covalent organic frameworks (COFs) capable of visible-light-driven overall water splitting was proposed. Through high-throughput first-principles computations and experimental validations, seven 2D COFs with overall water splitting capability were identified from the CoRE COF database. The photocatalytic activities of these COFs were verified and optimized through preliminary experiments, achieving hydrogen and oxygen production rates of 80 and 32 μmolg(-1) h(-1) respectively, without the need for sacrificial agents. This work represents a promising approach to accelerate the discovery and design of COFs for visible-light-driven overall water splitting.
