Graphene-like two-dimensional layered materials have attracted quite a lot of interest because their sizable band gaps and potential applications. In this work, monodisperse tin disulfide (SnS2) nanosheets were successfully prepared by simple solvothermal procedure in the presence polyvinylpyrrolidone (PVP). Large PVP molecules absorbing on (001) facets SnS2 would inhibit crystal growth along [001] orientation protect product from agglomeration. The obtained diameters ca. 0.8–1 μm...
In order to overcome the disadvantage of poor mechanical properties and limited application rubber concrete, basalt fiber was used reinforce concrete prepare a new composite material. The axial compression test acoustic emission were performed verify advantage fiber-reinforced in anticracking ability. purpose this paper is further expand civil engineering, so that waste products could be more sustainable utilization for protecting ecological environment. results revealed as content reached...
This paper studies the mechanical properties of porous asphalt concrete with styrene-butadiene-styrene (SBS) polymer modified bitumen as binder, steel slag aggregate and crumb rubber basalt fiber modifiers. First, appearance, mechanics, chemical composition high-temperature stability were studied by some equipment. Then, three kinds SBS binder produced, Namely, (CR-PAC), (BF-PAC), composite (CM-PAC). Finally, PACs through Marshall test, freeze-thaw splitting low-temperature permeability...
Single-layered graphene has unique electronic, chemical and electromechanical properties. Recently, graphite exfoliation in N-methylpyrrolidone molten salt been demonstrated to generate monolayer exfoliated sheets (EGS). However, these solvents are either high-priced or require special care have high boiling points viscosities, making it difficult deposit the dispersed onto substrates. Here we show a universal principle for of water single-layered several-layered via direct highly oriented...
In this paper, the performance of environmentally friendly porous asphalt mixture was optimized by response surface method. Taking asphalt-aggregate ratio, crumb-rubber content, and basalt fiber content as independent variables, air void, Marshall stability, flow value, quotient, Cantabro particle loss are values. The best model determined fitting experimental data. After influence variables on values clarified, models were used to optimize dosage asphalt, crumb rubber, through comprehensive...
•The kinetics of adsorption and desorption process were revealed, respectively, by monitoring a fluorogenic carbon dots on the surface graphene oxides at single turnover level•By regulating equilibrium desorption, mechanism for simultaneous promotion has been discovered•A accelerator could play satisfactory double action, i.e., promoter thermodynamics A knowledge behavior sorbates adsorptive site (SAS) is key to optimizing chemical reactivity catalysts. However, direct identification SASs...
Recurrent spontaneous abortion (RSA) is defined as the loss of two or more consecutive intrauterine pregnancies that are clinically established early in pregnancy. To date, etiology and underlying mechanisms RSA remain unclear. It widely thought impairment decidualization inclined to induce subsequent pregnancy failure leads dysregulation extra-villous trophoblast invasion proliferation through maternal–fetal cross talk. However, mechanism has yet be understood. In our study, we demonstrate...
To quantitatively evaluate the effect of diatomite, basalt fiber, and their interaction on high- low-temperature performance, as well viscoelastic performance asphalt, softening point tests, Brookfield viscosity dynamic shear rheometer (DSR) bending beam (BBR) tests were conducted. Based DSR results at different temperatures, shift factors deduced by a new method adopted to plot master curves asphalt. The Christensen-Anderson-Marasteanu (CAM) model was then used fit analyze effects contents...
A novel hybrid technology that ultrasonic-assisted electrochemical discharge grinding combined with in-situ ultrasonic broaching was used to process an array of square microholes on quartz glass. Diamond abrasive particles were directly added the electrolyte simultaneously perform machining and grinding. Because diamond electrolyte, it could be for both processes replacing slurry or electrode unnecessary. This method removes material through simultaneous melting, etching, impact The proposed...
Exposed to aggressive environments, the rebar in reinforced concrete (RC) bridges will be corroded gradually. Durability of RC material mostly depends on corrosion behavior. In this research, influences crack were investigated. Firstly, specimens with different number, width and spacing prepared was conducted through an accelerated chloride penetration method. Then, current densities calculated from electrochemical test methods including liner polarization (LP), Tafel potentiodynamic (TPP)...
Nb-doped SrTiO3 thermoelectric ceramics with different niobium concentrations, sintering temperatures and Sr-site vacancies are successfully prepared by high energy ball milling combined carbon burial sintering. For fully understanding the effect of doping on SrTiO3, transport properties systematically investigated in a temperature range from 300 K to 1100 K. The carrier mobility can be significantly enhanced, electrical conductivity is quadrupled, when rises 1673 1773 (beyond eutectic (1713...
Abstract Thin gold (Au) films (10 nm) are deposited on different substrates by using a e-beam deposition system. Compared with sapphire and SiO 2 surfaces, longer migration length of the Au adatoms is observed MoS which helps in formation single-crystal film surface at 200 °C. The results have demonstrated that assistance van der Waals epitaxy growth mode, 3D metals can be grown 2D material surfaces. With improved crystalline quality less significant grain coalescence sheet resistance 2.9...
Light-emitting diodes (LEDs) are used widely, but when operated at a low-voltage direct current (DC), they consume unnecessary power because converter must be to convert it an alternating (AC). DC flow across devices also causes charge accumulation high density, leading lowered LED reliability. In contrast, gallium-nitride-based LEDs can without AC-DC being required, potentially greater energy efficiency and this study, we developed multicolor AC-driven light-emitting device by integrating...
A chloride ion is a key factor affecting durability of reinforced concrete (RC) structures. In order to investigate migration in cracked concrete, considering the mesoscopic heterogeneity modeled here treated as four‐phase composite consisting aggregate, mortar, crack, and interfacial transition zone (ITZ). this paper, two‐dimensional finite element models with different crack widths quantity are established control parameters determined based on nonsteady‐state (NSSCM) test. addition,...
