A linear spot-type multipass cell-enhanced fiber-optic photoacoustic gas microprobe is proposed. To further reduce the volume of chamber and enhance signal, we designed cross section tube as a slit with height 10 mm width 1.5 mm. The only 210 μL. Through theoretical analysis multiphysical field simulation, intensity more than 6 times that traditional circular section. cantilever beam integrated into forms Fabry–Perot (FP) interferometer an optical fiber, achieving enhanced detection. By...
An innovative additive manufacturing (AM) system using low power pulsed laser assisted MIG arc welding (L-M) was proposed to manufacture metal products. With the purpose of revealing how width and height dimension manufactured thin-wall component are affected by power, present study has been carried out. The decreased with increasing within a certain range increased proportionally under equal deposition rate. fluctuation reduced while adding laser, both standard deviation more than 50% when...
Transforming growth factor β1 (TGF‑β1) has been suggested to be a candidate cytokine in the field of bone tissue engineering. Cytokines serve important roles engineering, particularly repair damage; however, underlying molecular mechanisms remain unclear. In present study, effects TGF‑β1 on osteogenesis and motility hFOB1.19 human osteoblasts were demonstrated via phenotype gene expression cells. Additionally, role phosphatidylinositol 3‑kinase/protein kinase B/mammalian target rapamycin/S6...
A novel wire arc additive manufacturing process is proposed to produce porous metal (PM). The innovation convert harmful welding pore defects into a beneficial structure of PM, and then the PM parts can be manufactured layer by layer. Air was transferred molten pool as promoters maximize formation defects. triple-wire indirect used for fabricating multi-layer reduce interlayer filling. primary advantage that directly macro-pore structures rather than depositing walls along micro paths in...
Nonalcoholic fatty liver disease (NAFLD) is a growing global health threat. Human milk oligosaccharides (HMOs) exhibit prebiotic properties that may alleviate NAFLD progression. Herein, our study demonstrates 3-fucosyllactose (3-FL), distinctive and crucial HMO, significantly attenuates body weight gain, enhances hepatic lipid metabolism, reduces inflammation in high-fat diet (HFD)-induced mouse model. These findings suggest its potential as dietary supplement for preventing alleviating...
Hexagonal BaAl2O4:Eu2+, Dy3+ polynary complex nanotubes with long-lasting phosphorescence were obtained through a facile coprecipitation approach followed by postcalcining reaction in weak reducing atmosphere. In the case of low annealing temperature, anion vacancies and surface stress can induce lattice contraction due to poor crystallininty; moreover, Eu2+ ions occupy two different crystallographic Ba2+ sites symmetry, resulting an appearance double emission peaks. For sample annealed at...
The 7075-T6 aluminum (Al) alloy is a high-strength material with great application potential. However, the tensile strength and elongation of its arc-welded joints are severely reduced compared to base metal (BM), only 57.3 % 14.4 BM values, respectively. To improve both plasticity simultaneously, novel post-weld composite treatment process combining solution treatment, partial rolling, natural aging (SRA) was proposed. SRA enhanced welded 84.5 83.1 BM, In different regions joints, involved...
Abstract This article gives a preliminary research on direct current (DC) double pulse metal inert gas (MIG) welding of magnesium alloys. It will be an effort for broadening the application this new MIG process. The unique parameters DC are selected to investigate their effects weld bead geometry size and appearance AZ31B Mg alloy, principles summarized. Then, butt joints produced with optimum stationary by using process, high quality surfaces without spattering, undercut, or discontinuous...
The activated flux coated wires are used to examine the effect of fluxes on weld penetration magnesium alloy. A series emission spectroscopy arc plasma for TIG welding with normal wire and developed. It is found that intensities spectra Mg I increase significantly when used. All can welding. electron temperature density estimated. result indicated decrease used; contrary, got enhanced. believed current increases increase, which one reasons depth
A simple and efficient combustion method has been developed for pure doped ZnO polycrystalline nanobelts. Eu3+ can form a supersaturated solid solution in the nanobelts annealed at 600 °C. Photogenerated electrons cannot transfer effectively from conduction band (CB) to excited states of incorporated ions exchange energy. However, trap level occurring about 90 meV below CB minimum, thus photogenerated relax rapidly shallow then recombine with free-holes valence edge, becoming dominant...
Long-lasting phosphor SrAlxOy:Eu2+, Dy3+ (x = 4) nanostructures were synthesized through a facile but efficient combustion technique followed by post-annealing reaction at different temperatures. During the synthesis process, triethanolamine (TEA) can not only be used as an organic fuel, also control morphology of nanostructured products. With increase in temperature, their transforms from nanosheets into semi-curled nanobelts due to crystal growth and edge curl effect, moreover, products...
