Metal species have a relatively high mobility inside mesoporous silica; thus, it is difficult to introduce the metal precursors into silica mesopores and suppress migration of during reduction process. Therefore, until now, controlled growth nanocrystals in confined space, i.e., channels, has been very challenging. Here, by using soft-enveloping reaction at interfaces solid, liquid, solution phases, we successfully control metallic template. Diverse monodispersed nanostructures with...
Biporous nanocarbon foams (NC foams) which have both nano-pores and micro-pores, were fabricated used to explore the liquid transportation in porous structures formed by nanomaterials. Scanning electron microscopy was utilized observe structure of NC foams. Capillary rise tests using acetone as working fluid conducted IR thermal imaging method. The results show that capillary height foam with 65 μm micro-pore size 47% higher than 9 50 s. performance reduced when its density 60 mg/cm3. A...
Basalt rockwool wastes with large output, which are toxic and require expensive environmental treatment, produced during the production of rock wool. Hence, it is urgent to find an effective method reuse these materials. In this study, polyaniline (PANI)-coated basalt (BRWs) were prepared as fillers serve in coatings for anticorrosion study. Results show that PANI-coated BRW (PANI@BRW) had enhanced dispersion stability several conventional solvents improved performance epoxy resin coating. A...
Background Inorganic mesoporous materials exhibit good biocompatibility and hydrothermal stability for cell immobilization. However, it is difficult to encapsulate living cells under mild conditions, new strategies immobilization are needed. We designed a "fish-in-net" approach encapsulation of enzymes in ordered silica conditions. The main objective this study demonstrate the potential cells. Methodology/Principal Findings Zymomonas mobilis were encapsulated silica-based conditions by using...
In the present paper, monotonic axial compression test of gangue aggregate concrete filled Fiber reinforced polymer (FRP) and thin-walled steel double tubular columns (DTCC) was carried out, FRP (CFFT) were designed as a comparison. The main experimental factors confinement level jacket, relative diameter ratio (the outer tube to inner jacket), different strengths concrete. results show that bearing capacity ductility in CFFT significantly improved. As local buckling effectively inhibited,...
The studies of organic thermoelectric (TE) materials mainly focus on conductive polymers due to their conjugated molecular structures and high intrinsic electrical conductivity. When the polymer is mixed with certain insulating polymers, power factor was found enhanced. It doubtful that partially structure beneficial TE performance. Polyacrylonitrile (PAN) an a non-conjugated in its backbone, however, it has after thermal treatment. In this work, composite PAN multi-walled carbon nanotubes...
A novel mesoporous polymer-based composite, C7-BTBP/XAD-7, was prepared by impregnating 6,6'-bis(5,6-diheptyl-1,2,4-triazin-3-yl)-2,2'-bipyridine (C7-BTBP) into the pores of polymeric XAD-7 carrier. The microstructure material characterized scanning electron microscopy (SEM), nitrogen adsorption-desorption isotherms, and thermogravimetric analysis (TGA). selective adsorption Pd(II) onto C7-BTBP/XAD-7 from a HNO3 medium containing some typical metals, including Ru(III), Fe(III), Mo(VI),...
The injection scheme of an RBCC(Rocket-based combined cycle) engine at scramjetmode using the strut base as a flameholder is carried out by commercial software CFD++ code. Three dimensional steady Reynolds time-averaged Navier-Stokes (N-S) equations were chosen control equations. Turbulence closure was achieved model that combines 2 equation cubic k-e model. turbulent Schmidt (Sct) and Prandtl (Prt) numbers set to 0.3 0.89 respectively. Cases reacting nonreacting considered. Besides effects...
Metal redox methodology is utilized to synthesize magnetic binary MnAl and ternary MnAlCo nanoalloys.
Based on chaotic scrambling, we proposed a digital image watermarking scheme in interpolatory orthogonal multiwavelets transforming domain. At first, the logistic mapping and arnold transformating are employed to scramble original image, then watermark information is embedded into middle frequency coefficients of image. Experimental results showed that has high secrecy intensity ability against general processing attack.
Ramjets exhibit undesirable combustion instabilities under certain operating conditions. In this paper, large-eddy simulation(LES) and premixed model have been efficiently implemented to study in ramjet combustors. The main objective is predict dominant frequencies various flow features of the Combustion dump combustor numerically simulated. Low-frequency, large-amplitude are observed, instability flame spread during conditions good agreement with experimental observations. results show...
