A novel sensing hybrid-material of Au nanoparticles (Au NPs)-functionalized ZnO nanowires (Au–ZnO NWs) was successfully synthesized by a two-stage solution process. First, NWs were fabricated via low-temperature one-pot hydrothermal method with SDSN introduced as structure-directing agent. Afterward, the as-prepared used supports to load NPs small sizes precipitating HAuCl4 aqueous ammonia. The obtained samples characterized means XRD, SEM, TEM and EDX. Both pristine Au–ZnO practically...
In this paper, brookite-TiO2/α-Fe2O3 heterostructured nanorods were synthesized by a facile two-step solution approach without using any templates or surfactants. α-Fe2O3 first successfully obtained via simple method at room temperature. The further employed as supports to construct nanoheterostructures for gas sensor application. based on the as-fabricated TiO2/α-Fe2O3 exhibited an excellent gas-sensing performance, with markedly enhanced responses in comparison pristine nanorod sensor, and...
Spinel ZnFe<sub>2</sub>O<sub>4</sub> nanoparticle-decorated rod-like ZnO nanoheterostructures were one-pot synthesized for detecting <italic>n</italic>-butanol, ethanol, acetone, methanol and formaldehyde.
For the first time, ultrasonic surface rolling processing (USRP) technology was applied to a real bearing raceway, and finite element simulation model for USRP on raceway established. Practical tests were conducted evaluate integrity of before after treatment. The parameters optimized using Taguchi-gray correlation analysis. results show that optimal process 7224 are: an amplitude 10 μm, static pressure 2400 N, spindle speed 45 rad/min, times 7. In USRP, residual compressive stress from...
In this contribution, ZnFe2O4–ZnO composite hollow microspheres were successfully synthesized by a glucose-assisted hydrothermal method only using Fe(NO3)3·9H2O, Zn(NO3)2·6H2O and glucose as starting materials, followed calcination treatment. The characterization results from scanning electron microscopy (SEM), transmission (TEM), X-ray powder diffraction (XRD) photoelectron spectroscopy (XPS) revealed that the as-synthesized microspheres, with diameter range of 1 to 2.5 μm shell thickness...
In this work, TiO2(B) nanoparticle (NP)-functionalized WO3 nanorods (NRs) were synthesized by a two-step solution strategy, with hydrothermal process for NRs and hydrolyzation of Ti(OBu)4 the functionalization NPs. Various techniques, including scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD), photoelectron spectroscopy (XPS), employed to investigate morphology, microstructure, crystalline nature chemical composition prepared NP-functionalized NRs. SEM TEM...
1D unique porous α-Fe2O3 nanoshuttles (NSs) were synthesized by a template-/surfactant-free low temperature hydrothermal approach (60 °C, 48 h), followed simple annealing process (300 1 h). The prepared NSs (ca. 40 nm in diameter and 250 length) have rugged surface structure with numerous nanopore inlets (about 1–10 diameter). time dependent experiment demonstrated that the formation of is gradual process, which underwent growth, strong, spilt, re-spilt processes as reaction times prolonged...
This paper presents the fabrication and characterization of a resonant pressure microsensor based on SOI-glass wafer-level vacuum packaging. The SOI-based consists pressure-sensitive diaphragm at handle layer two lateral resonators (electrostatic excitation capacitive detection) device as differential setup. were packaged with glass cap using anodic bonding wire interconnection was realized mask-free electrochemical etching approach by selectively patterning an Au film highly topographic...
Sika pilose antler type I collagen (SPC-I) have been reported to promote bone marrow mesenchymal stem cell (BMSC) proliferation and differentiation. However, the underlying mechanism is still unclear.This study investigates molecular mechanisms of SPC-I on BMSC differentiation osteoblast (OB) in vitro.The primary rat was cultured exposed at different concentrations (2.5, 5.0 10.0 mg/mL) for 20 days. The effect BMSCs evaluated through detecting activity alkaline phosphatase (ALP), ALP...

The relationship deviation basilar artery(BA) in directions location pontine infarction are also investigated.A cohort 106 patients(74 males 32 females) who satisfied diagnostic criteria for VBD were recruited this classified according to bifurcation height position BA, as well measured value pontine, which includes rCBF,...
Porous Au/α-Fe2O3 NRs are one-pot synthesized, and used as gas sensors for in situ VOCs detection. The sensor shows four times higher response to C6H6 than a pure α-Fe2O3 short response/recovery time (<30 s), which may be useful establish an effective real-time monitoring system environmental protection oil reservoirs' prediction.
This paper presents a vacuum-packaged resonant pressure sensor featured with high sensitivity and linearity using dual resonators. The frequency difference between these two resonators is used to represent pressure, so that the nonlinear responds of each resonator eliminated also improved at same time. sensitivities were matched through diaphragm uniformity controlled anchor undercut, which leaded better linear performance. With this method, error reduced from 1.3% F.S. 0.2% over range 0 250...
Lumbar spinal stenosis (LSS) is a prevalent and disabling cause of low back leg pain in elderly people nerve root sedimentation sign (NRSS) has been demonstrated to have high sensitivity specificity diagnosing LSS selected patients. The purpose this study was investigate the diagnosis predictive value NRSS.The clinical imaging data 176 patients diagnosed with 156 non-specific (LBP) were analyzed retrospectively. Transverse magnetic resonance images (MRI) narrowest canal all acquired graded...
