Toward Energy‐Efficient Alkaline Water Electrolysis: Advances in Mass Transport Optimization and Electrolyzer Design

open access: yesAdvanced Energy Materials, EarlyView.
Component‐level engineering in alkaline water electrolysis (AWE) is systematically analyzed, highlighting strategies in porous electrodes, bubble management, membranes, and flow fields to overcome mass‐transport bottlenecks. By linking microstructural design to multi‐scale ionic and gas transport, this Review establishes design principles that connect ...

Hybrid Learning Enables Reproducible >24% Efficiency in Autonomously Fabricated Perovskites Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Perovskite solar cells are promising candidates for scalable renewable energy technologies, but progress is often limited by complex fabrication processes and poor reproducibility. Here, we develop integrated workflows that combine automated high‐throughput fabrication with hybrid data‐driven modeling to design, build, and evaluate thin‐film ...

Exploring the Inhomogeneous Nature of Li Intercalation and Li Plating on Graphite Anodes—An Experimental Study Combining Inert Gas High‐Resolution Light Microscopy with Colorimetric and Machine Learning‐Based Image Analysis

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Graphite anode lithiation and lithium plating are explored using high‐resolution light optical microscopy under inert gas atmosphere. Colorimetric analysis and machine learning reveal lithiation stages depending on C‐rate and state‐of‐charge. With increasing C‐rate, heterogeneity of lithiation increases, resulting in up to three phases coexisting in ...

Influence of thermal boundary conditions on heat transfer from a cylinder in cross flow [PDF]

open access: yes
Local heat transfer data over the leading surface of a cylinder in crossflow were obtained for a Reynolds number range of 50,000. The cylinder was operated at both uniform-wall-temperature and uniform-heat-flux thermal ance of 80 deg from the front ...

Does Contract Farming Improve Diet Quality? The Case of Senegalese Smallholders

open access: yesAgribusiness, EarlyView.
ABSTRACT The institution of contract farming has gained prominence in most developing countries owing to its numerous benefits. While several studies have already highlighted the welfare benefits of contract farming, very few have investigated the effects on diet quality, despite poor quality diets being a serious challenge in most parts of the ...
