Rational Construction of Indium-TiO2 Interfacial Composites for Boosting Urea Electrosynthesis

The electrocatalytic co-reduction of CO2 and nitrate to urea offers a sustainable route for carbon fixation, nitrogen waste recycling, and high-value chemical production. However, the rational design of efficient electrocatalysts with synergistic activation capability toward both...

Temperature–blending ratio effects on ash resistivity during corn stover/lignite co-firing for bioenergy applications

Corn stover co-firing provides a practical route for integrating agricultural residues into existing coal-fired power systems, but biomass-induced changes in ash behavior may affect particulate control and the operational reliability of bioenergy utilization. In this study, the r...

Economic feedback-guided forecasting and scheduling for microgrids using rolling model predictive control

Microgrid rolling energy management often follows a decoupled forecast-then-optimize workflow, where forecasts are trained separately from downstream rolling model predictive control (MPC) scheduling. However, lower statistical forecasting errors do not necessarily reduce operati...

The particle size effect on the uplift capacity of shallow circular plate anchors in sand using DEM

To address the inherent particle size effect (PSE) in physical and DEM modeling, 3D DEM models of shallow circular plate anchors in sand were developed using PFC3D. Following validation against centrifuge data, the influence of the effective plate diameter-to-mean particle size r...

Ag-induced interfacial electronic regulation of hierarchical In2O3 microflowers for room-temperature H2S sensing

Hydrogen sulfide (H 2 S) is a highly toxic, corrosive, and flammable gas. Therefore, rapid and low-power monitoring under room-temperature conditions is of great importance. However, room-temperature chemiresistive metal-oxide sensors generally suffer from weak H 2 S adsorption a...

Achieving high-efficiency thermoelectric collaborative storage based on a temperature-matching strategy: Combining calcium looping and reversible solid oxide cells

To address the energy storage challenge in large-scale renewable energy integration, the concentrating solar power (CSP) with calcium looping (CaL) system provides a viable solution for long-duration energy storage. However, such a system inherently faces the problem of balancing...

Weather-guided decomposition and hard-routing expert modeling for short-term photovoltaic power forecasting

Solar energy has become a pivotal renewable resource in modern power systems; however, the stochastic and weather-dependent variability of photovoltaic (PV) generation continues to challenge accurate power forecasting and grid operation. This study proposes a weather-adaptive for...

Synergistic optimization of the Han-to-Wei project under dry conditions via the MOEA/D-PFE: a case study of the Huangjinxia reservoir

Interbasin water transfer (IBWT) projects are essential for regional water security, yet complex trade-offs exist among reservoir operation objectives under variable hydrological conditions. Taking the Huangjinxia Reservoir of the Han-to-Wei River Diversion Project as a case stud...
