In this study, we referenced the formation principle of rust in nature and FeOOH quantum dots (QDs) were prepared using a metal-solating process. The QDs exhibited an average diameter 3.5 nm with well crystallinity. Furthermore, as-prepared deposited on ZnO nanorods film as co-catalyst for water oxidation. crystal phase, microstructures, optical properties synthesized films established through X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), Raman...
In this work, DyVO<sub>4</sub>/WO<sub>3</sub> heterojunction plate arrays were first fabricated on FTO using a hydrothermal method for WO<sub>3</sub> vertical and dipping–annealing process the deposition of DyVO<sub>4</sub> nanoparticles.
Cement stabilization is a widely applied technique in improving the workability and geotechnical properties of soft clay. This paper investigated influence cement on soil–water characteristic curve (SWCC) deformation behavior unsaturated cement–stabilized The combined effect cementation partial saturation hydromechanical cement-stabilized soils was discussed. SWCC stabilized soil measured full suction range under drying wetting paths using pressure plate method, filter vapor equilibrium...
This paper presents a constitutive model for simulating the stress–strain behavior of overconsolidated structured soils. The extends scope previous 10-parameter proposed by authors It uses variable normal compression index dependent on degree structure to simulate degradation during loading. also introduces concept subloading plasticity prevent peak shear strength soils from being overestimated in state. performance describing mechanical with different initial overconsolidation ratios is...
Magnesium oxychloride cement (MOC) is an environment-friendly often used for stabilizing soft soils because of its exceptional mechanical properties. In this study, the influence curing temperature on strength development MOC-solidified clay explored, considering different MgO/MgCl2 molar ratios. Different tests were carried out to study corresponding effects. The results show that effect differs greatly from cement-solidified soil. Increasing leads reduction, whereas decreasing increases...
Herein, a theoretical study on Nb‐doped LiNiO 2 cathode materials for Li‐ion batteries is performed based density functional theory within the projector augmented wave method. Due to stronger NbO interaction, Ni‐rich modified by Nb has better electronic conductivity, higher potential, and larger O ‐vacancy formation energy. During charging discharging process, doping can reduce lattice distortion, which conducive improve cycle performance of electrode. This work provides new insight into...
Based on the concept of subloading plasticity, a constitutive framework, using mean skeleton stress and effective degree saturation as fundamental variables, is proposed for capturing coupled hydro-mechanical behaviours overconsolidated unsaturated soils. This framework can be reduced to Modified Cam-Clay model when suction becomes zero initial overconsolidation ratio (OCR) equal 1.0. Compared with models in literature, main advantage that it capable modelling interaction soils, such...
Unsaturated soil shows complex mechanical behaviours compared to saturated soil. A number of constitutive models for unsaturated have been proposed. However, these suffer limitations. In this paper, a new model has proposed in terms effective stress and degree saturation based on the modelling assumption about relationship between hardening effect saturation. The volume change equation gives explanation Then, an alternative approach simulate coupled hydraulic hysteresis influence soil–water...
The carbonated reactive magnesia (CRM) method is superior in energy conservation, carbon capture, and rapid solidification soil improvement. It has been revealed that CRM could cause apparent volumetric expansion during carbonation, which may compaction impact on the surrounding soils when used for soft foundation However, this hasn't discussed systematically. In study, evolutions of stress (σEx) (ΔV) carbonation process were successfully monitored. Two factors, including MgO content (Cm)...
The compression line of structured soils is highly nonlinear in the space void ratio against logarithmic mean or vertical effective stresses. variation compressibility with loading attributed to structure degradation. In this paper, degree newly defined, and a new volume change equation for established by using modified stress as variables. influence degradation on mechanical behavior explained dependent normal index. validity approach examined via incorporating defined into Modified...
Few studies have reported the effect of cement content and surcharge pressure on drying−wetting durability cement-stabilised clayey soil. The aim this research was thus to understand these two factors Clayey soil, dredged from Taihu Lake in Wuxi, China, stabilised with three different contents. Drying−wetting tests were performed soil under five pressures direct shear conducted using a modified conventional device. found significant appears decrease strength low content, whereas increase...
In the rock fragmentation process, disc cutter, tunnel boring machine's main rock-breaking tool, often lose capability because of improper selection magnitude interference between cutter ring and body. The three-dimensional software SOLIDWORKS finite element ANSYS is used to build mathematical model. And aim was optimize design its body, when cutting granite stratum. We analyzed stress-strain transmission torque on contact surface, finally obtained optimal (0.05mm). It could be verified with...
