Anatase, rutile, and especially brookite nanocrystals have been selectively synthesized in this work via a redox route under mild hydrothermal conditions (180 °C, 3 h), employing trichloride as the titanium source ammonium peroxodisulfate (APS), hydrogen peroxide, nitric acid, or perchloric acid oxidant. Characterizations of three pure phases were achieved by XRD, Raman spectroscopy, FTIR, TG, HRTEM, UV−vis, BET. The use APS consistently yields anatase, but particle morphology can be tuned...
Uniform red-phosphor spheres (∼60−300 nm in diameter) of Y2O3:Eu3+ binary and (Y,Gd)2O3:Eu3+ ternary systems exhibiting excellent emission at 610 have been converted from their colloidal precursor synthesized via homogeneous precipitation. The (approximate composition: [(Y1-xGdx)1-yEuy](OH)CO3·1.3H2O, x = 0−0.5 y 0−0.11) are directly solid solutions, but arising sequential nucleation each the has more Gd especially Eu while having less Y going particle surface to core. Eu3+ is effective than...
Layered double hydroxides (LDHs) have attracted broad attention as cathode materials for hybrid supercapacitors (HSCs) because of their ultrahigh theoretical specific capacitance, high compositional flexibility, and adjustable interlayer spacing. However, reported, capacitance LDHs is still far below the value, inspiring countless efforts to these ongoing challenges. Herein, a hierarchical nanocage structure assembled by NiCo-LDH nanosheet arrays was rationally designed fabricated via facile...
Uniform spheres of (Y1−xGdx)2O3 (x = 0–1) are valuable for applications in phosphors, optical ceramics fabrication, and combinatorial synthesis. We made this work such particles by thermal decomposition precursors synthesized via homogeneous precipitation. Growth kinetics composition evolution the precursor were investigated detail, it was identified first time that (1) differential nucleation occurs with regard to Y Gd, as a result concentration gradients exist within each particle mixed...
Two-dimensional (2D) materials have shown outstanding properties that make them the of choice for future semiconductor and flexible nanoelectronics. Hexagonal boron nitride nanosheet (BNNS) is one most studied 2D due to its extraordinary potential applications. The synthesis large, homogeneous, few-layered BNNS, however, remains challenging. Among various synthetic routes, chemical vapour deposition (CVD) preferred on grounds yield large BNNS with controllable atomic layers minimal...
This review highlights recent research advances in functionalised hexagonal boron nitride for energy conversion and storage applications.
Traditional fluorescent anti-counterfeiting materials usually display monochromatic luminescence at a fixed excitation mode, which greatly reduces the efficiency of applications. Recently, developing multilevel material with tunable photoluminescence is hot topic in arena advanced anti-counterfeit research. Here, spinel-structured solid solutions ZnGa2–x(Mg/Ge)xO4:0.001Mn (x = 0–1.2) have been successfully synthesized by high-temperature solid-state reaction. In this solution, Mn2+ and Mn4+...
Doping Li + resulted in oxygen vacancies and green-yellow emission. Changing the excitation wavelength/temperature yielded varied visible/NIR lights afterglows, which contributed to a dynamic luminescence.
Doping Li + /Ga 3+ in ZnGa 2 O 4 :Cr splits the energy level of electron traps into shallow and deep traps, which makes developed phosphors be successfully excited by a low-energy NIR light suitable for long-term biological imaging.
Orthotropic steel deck (OSD) are widely used in bridges because of their many advantages, but the structures and stresses OSD complex sensitive to fatigue. Based on model test, structural fatigue analysis is carried out by using extended finite element method (XFEM) understand reveal causes detail cracks generation propagation at welding ends diaphragms, U-ribs, which main details deck.

Dependent on the solubility of titanium-oxo-clusters, molar ratios Ti/Cd in composite can be adjusted precisely. Herein, a soluble solid-state titanium-oxo-cluster is employed as Ti raw reactant to fabricate TiO2/CdS photocatalyst with TiO2 nanoparticles isolated surface CdS nanorods for highly efficient degradation tetracycline (TC). The comparative experiment shows that ratio at 0.5 exhibits best photocatalytic performance, which degrade 95% TC an initial concentration 10 mg/L under 12 min...
Abstract The continuous growth of Li dendrites and volumetric deformation severely impede the commercial application metal anodes. To regulate stripping/plating, electrodeposition or magnetron sputtering is extensively utilized to fabricate lithiophilic‐metal deposited 3D hosts. However, binding force between host weak, inevitably leading numerous cracks/defects lithiophilic‐surface‐layer during plating/stripping. Herein, a quasi‐gradient (Cu‐Cu 3 Sn‐Sn‐SnO 2 ) skeleton consisting...
