Streamflow prediction is essential for water resources management, flood forecasting, and climate resilience. Long short-term memory (LSTM) networks have advanced large-sample hydrology through cross-basin learning, but their recurrent architectures have limited ability to capture long-range temporal dependencies, particularly for medium-range forecasting. Meanwhile, exist…

This work describes a pilot-scale, thermally controlled gas–liquid absorption column designed for point-source carbon dioxide (CO₂) capture, featuring a 4-m tall, 0.3-m diameter absorber with a capacity of up to 1 t of CO₂ per day. Flue-gas conditions are simulated using a natural gas-fired power generation engine. A key advancement is the integration of a 3D-printed proce…

Understanding the atomic-scale origins of corrosion in molten fluoride salt environments is essential for developing resilient materials for advanced nuclear and energy systems. Here, we investigate the response of an epitaxially grown Fe-8Cr alloy film to localized FLiNaK salt exposure to elucidate early-stage degradation mechanisms. High-resolution scanning transmission…

This study correlated the thermally induced distortion of large-format additive manufacturing (LFAM) printed composite structures to the alignment of reinforcing fibers. During LFAM material extrusion, shear forces near the nozzle wall align reinforcing fibers in the print direction (x-axis). This produces a complex microstructure comprised of a “shell” of highly aligned f…

Conference Paper
Wireless power transfer (WPT) has been proposed for charging of electric cars, robots, and drones to increase battery capacity factor, charging reliability, and autonomous functionality. Multiphase WPT systems using large-diameter coils have been explored to increase specific power transferred, enhance tolerance to misalignment, and reduce stray-field emissions. Stationary…

This study investigates the influence of cyclic loading frequency on the fatigue limit of additively manufactured-compression molded (AM-CM) short carbon fiber thermoplastics (20 wt% CF-ABS). Accelerated fatigue characterization was performed using passive infrared thermography under a staircase loading protocol at 5, 10, 15, and 20 Hz. Displacement accumulation, stabilize…

The Td phase of tungsten ditelluride (WTe2), a noncentrosymmetric transition metal dichalcogenide, hosts rich correlated phenomena, topological states, and nonlinear transport responses. However, the scalable synthesis of high-quality few-layer WTe2 with precise layer control remains challenging. Here, we report a water-assisted chemical vapor deposition approach that dete…

Saccharolytic bacteria are of increasing interest due to their importance in human health and the environment. In particular, their abilities to utilize diverse plant polysaccharides make them attractive candidate organisms for production of lignocellulosic biofuels. Thermoanaerobacterium thermosaccharolyticum is a thermophilic saccharolytic anaerobe able to utilize a vari…
