A totally homogeneous, molecular, visible-light-driven water oxidation system is reported. The three components are (i) a catalyst, 1 (a RuIV4O4 cluster stabilized by oxidatively resistant [SiW10O32]8- ligands); (ii) photosensitizer, [Ru(bpy)3]2+; and (iii) sacrificial electron acceptor, S2O82−. Dioxygen formed rapidly with an initial turnover frequency of ∼8 × 10−2 s−1 estimated quantum yield (defined as the number O2 molecules per two photons absorbed) ∼9%.
The novel organic-inorganic hybrid material [Cd(PT)(H2O)]n (1; PT = phthalate) has been hydrothermally synthesized. X-ray diffraction study reveals that 1 exhibits an interesting two-dimensional (2D) honeycomb framework constructed from [CdO7] single helical chains linked via oxygen atoms of the ligands, which adopt μ6-bridging coordination mode. A physical properties demonstrates it a strong fluorescent emission in solid state at room temperature.
This study compares the synthesis and structure of poly(oleic diacid-co-glycerol) that results by using immobilized Candida antarctica Lipase B (Novozym 435, N435) dibutyl tin oxide (DBTO) as catalysts. By N435 catalysis an oleic diacid to glycerol molar ratio 1.0:1.0, resulting polyester number-average molecular weights (Mn) were 6000 g/mol at 6 h 9100 24 with low branching degree (Den% 13%−16%). 13C NMR spectra these polyesters revealed their chain-ends consist exclusively monosubstituted...
A polyoxoniobate/g-C3N4 nanoporous material with functional groups has been synthesized by using carbon nitride (g-C3N4) and hexaniobate (K8Nb6O19•10H2O, abbreviated as NbO) precursors. The structure compositions of the as-prepared nanomaterials were characterized XRD, FT-IR, SEM, TEM XPS. These two kinds materials interact each other forming a hybrid composite, which can be used an adsorbent for removing cationic dye (methylene blue, MB) from wastewater excellent adsorption capacity....
Strength is usually compromised with toughness of polymer blends. We report a new way to synchronously strengthen and toughen typical blend epoxy resin/nitrile-butadiene rubber (EP/LNBR) Janus nanosheets (JNs). The silica-based JNs contain reactive epoxide group nitrile-butadiene on the opposite sides. They are robust high strength toughness. covalently bound at EP/LNBR interface upon blending cross-linking, which can effectively transfer stress in between two phases. At saturation coverage...
Broadband absorption of electromagnetic waves in different wavelength regions is desired for applications ranging from highly efficient solar cells, waste heat harvesting, multi-color infrared (IR) detection to sub-ambient radiative cooling. Taper-shaped structures made up alternating metal/dielectric multilayers offer the broadest bandwidth so far, but face a trade-off between optical performance and material choice, i.e., those with utilize exclusively CMOS-incompatible materials,...
SiC wafers, due to their hardness and brittleness, suffer from a low feed rate high failure during the dicing process. In this study, novel dual laser beam asynchronous method (DBAD) is proposed improve cutting quality of where pulsed firstly used introduce several layers micro-cracks inside wafer, along designed line, then continuous wave (CW) generate thermal stress around cracks, and, finally, wafer separated. A finite-element (FE) model was applied analyze behavior CW heating evolution...
The broadband perfect absorption of visible light is great significance for solar cells and photodetectors. realization a two-dimensional absorber in the range poses formidable challenge with regard to improving integration optical systems.

Flat lens or metalens, as one of the most important application branches metasurfaces, has recently been attracting significant research interest. Various reflective and transmissive metalenses have demonstrated in terathertz, infrared visible wavelength range. However, metalens operating ultraviolet (UV) range is rare. Moreover, development UV counterpart ones, falls far behind. In this work, with thorough investigation material properties, we propose a based on silicon dioxide (SiO2)...
As an emerging technique, mode division multiplexing (MDM) can effectively increase the data capacity in communication networks. High-performance multimode waveguide bends with small device footprints play indispensable role photonics and MDM technique.

Element doping and collaboration with other cocatalysts are two vital strategies to improve the photoelectrochemical properties overcome drawbacks of CdS for better photocatalytic performance. In this work, a series manganese cadmium sulfides (MnxCd1–xS) were obtained by solvothermal method. When x is equal or greater than 0.3, MnxCd1–xS composed Mn–Cd–S sosoloid MnS. Among all these products, Mn0.5Cd0.5S sample showed best hydrogen production (5.99 mmol g–1 h–1). To further elevate rate...
