Charge separation of particulate photocatalysts has been considered as the rate-determining step in artificial photocatalysis since finding Honda-Fujishima effect, whose efficiency is generally much lower than that natural photosynthesis. To approach its upper limit, it requires photoexcited electrons and holes be efficiently transferred to spatially separated redox reaction sites over a single photocatalyst particle. Herein, demonstrated spatial charge among facets BiVO4:Mo can notably...
Abstract This study aims to understand the connectivity characteristics of construction land during spatial evolution historic urban areas. The complex network analysis method is employed examine structure in four periods Changsha area. results indicate that morphology follows a repeated development pattern resembling cluster–mother–child relationship. Additionally, vulnerability use relationships very low, while overall stability decreases. equilibrium shows downwards trend, accessibility...
Traditionally, hot excitons or carriers generated in semiconductors were considered unfavourable for many applications, given that they may cause energy loss and device degradation.
Solid additives have drawn great attention due to their numerous appealing benefits in enhancing the power conversion efficiencies (PCEs) of organic solar cells (OSCs). To date, various strategies been reported for selection or design non-volatile solid additives. However, lack a general design/evaluation principles developing often results individual offering only one two efficiency-boosting attributes. In this work, we propose an integrated omnidirectional strategy designing By validating...
The interfacial fracture behavior of a stainless/carbon steel bimetal plate in uniaxial tensile test was investigated this paper. ultrasonic C-scan results showed that the internal had already appeared necking area before sample snapped, and occurred middle propagated with strain increase. fractography at interface between diffusion layer carburization stainless steel. contribution stress to analyzed by finite element method. FEM that, due different material mechanical properties, large...
Surface topography plays an important role in mixed lubrication. However, the influence of surface topography's morphological characteristics on lubrication performance is still not fully understood. In this article, we employ digital filtering and Johnson transformation system, use a plasto-elastohydrodynamic model to simulate lubricated contact between rough spherical surfaces with different characteristic parameters. The skewness, kurtosis, wavelength factor, that is, ratio...
Polyurethane (PU) filling materials are typically utilized in coal mines for and fortification order to guarantee safe support structures. Existing PU prone polymer fires, the current method of using additives cool them down has problem additive absorbing heat advance weaken foam wall reduce mechanical properties. This article addresses mismatch between phase change absorption hydrated salts exothermic polymerization PU. discusses thermal delay matching based on exhalation completion time...
In order to explore the influence of mining fracture lower coal seam previous upper mined in close distance seams, shallow multi-seam XinLiangyou mine county Pu Shanxi Province is selected as study field establish a numerical model seams with RFPA2D. The failure overburden well rule for development and redevelopment studied change vertical stress workface also analyzed. results indicate that: can lead increase height mined, which belong seams; Repeated cause decrease concentration...
Water and sand inrush is one of the most serious threats in some shallow coal mines China. In order to understand process inrush, experiments were performed obtain criterion for inrush. First, seepage tests carried out study hydraulic properties granular sandstone. The results indicate that velocity has a linear relation with porosity particle-size distribution parameter. Then, conducted investigate critical conditions occurrence. It determined zone can be clearly distinguished based on...
Abstract In shale gas reservoirs, the adsorption of can be multi-layer because presence small pores and heavy hydrocarbon components in kerogen portion source rock. Particularly, unconventional condensate become condensate, filling at pressures different from dew-point pressure bulk fluid. The commonly used Langmuir isotherm does not provide a valid model for capillary condensation it is based on assumption that mechanism monolayer adsorption. To solve this problem, we developed method to...
Recently, autonomous agents built on large language models (LLMs) have experienced significant development and are being deployed in real-world applications. These can extend the base LLM's capabilities multiple ways. For example, a well-built agent using GPT-3.5-Turbo as its core outperform more advanced GPT-4 model by leveraging external components. More importantly, usage of tools enables these systems to perform actions real world, moving from merely generating text actively interacting...
Large-scale solar-powered unmanned aerial vehicles possess the capacity to perform long-term missions at different altitudes from near-ground near-space, and huge spatial span brings strict disciplines for its attitude control such as aerodynamic nonlinearity environmental disturbances. The design efficiency performance are limited by gain scheduling of linear methods in a way, which widely used on aircraft present. So far, deep reinforcement learning has been demonstrated be promising...
