Suppressing polysulfide shuttling via a supporting electrolyte concentration-asymmetric (SEC-Asym) design based on electrolyte ionic strength for stable promoted Na–Polysulfide redox-flow batteries
Polysulfide species (Sn2-) that have high abundance and multi-electron redox processes are highly attractive for energy storage purposes, especially in grid-scale applications when pairing with Sodium (Na) for nonaqueous redox-flow batteries (NARFBs). However, the severe shuttling effect of polysulfide species causes self-discharge in batteries, which limits further develo…

On the existence of optimal set-valued decoders and their accuracy bounds for ill-posed inverse problems
Ill-posed inverse problems occur everywhere in the sciences, including medical imaging, radar, astronomy, etc., yielding underdetermined or ill-posed linear (non-linear) reconstruction problems. There are now a myriad of techniques to design decoders/reconstruction methods that can tackle such problems, ranging from optimisation-based approaches, such as compressed sensing…

Ductility control in an additively manufactured Al-7Si-0.3Mg-0.5Cu-1Fe alloy through heat treatments
Iron is a key ductility-limiting impurity in secondary Al-Si alloys that is responsible for impeding their widespread use in structural applications. An Al-7Si-0.3 Mg alloy with 0.5% Cu and 1% Fe (all in wt.%) was fabricated via laser powder-bed fusion to explore new microstructure engineering pathways with this processing route. While highly refined β-Al5FeSi intermetalli…

HydroTFT: a cross-basin attention model for multi-horizon rainfall–runoff prediction
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…

Modeling flow and mass transfer within hollow fiber packaging for gas separation
Hollow fiber membrane modules are used for gas purification by their selective permeation properties. Intensification of the process to minimize the retentate loss and gas pressure involves optimization at various scales. In this work, we outline a numerical investigation of the gas separation performance at the scale of fiber bundles and its impact on module performance.…

Thermally controlled absorber for enhanced point-source CO2 capture: Scaling up the process intensification packing technology
This work describes a pilot-scale, thermally controlled gas–liquid absorption column designed for point-source carbon dioxide (COâ‚‚) capture, featuring a 4-m tall, 0.3-m diameter absorber with a capacity of up to 1 t of COâ‚‚ 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…

Bridging Two Worlds: Introducing the Software Engineering and Scientific Computing Department
Scientific discovery increasingly depends on computing and software. Yet the practices used to develop scientific software often differ markedly from those in professional software engineering. To help bridge this gap, IEEE Computing in Science & Engineering (CiSE) is merging its existing Software Engineering and Scientific Programming departments into a unified department…
