Model Predictive Current Control for Low-Cost Shunt Active Power Filter

CSEE Journal of Power and Energy Systems
Performance of a three-phase shunt active power filter (SAPF) relies on the capability of the controller to track the reference current. Therefore, designing an accurate current controller is crucial to guarantee satisfactory SAPF operation.

Regioselective C‐H Oxyfunctionalization of Aliphatic Acids Through a Consecutive Biosolar Cascade

Small, EarlyView.
Photobiocatalytic regioselective oxyfunctionalization of aliphatic acids is realized by combining a dual‐alkali‐metal‐doped carbon nitride photocatalyst (NaK‐ACN) with CYP152A1 peroxygenase. The synergistic effect of co‐dopants modulates electron distribution and the surface electric field, enhancing 2e− ORR activity.

Strategies for enhancing sensitivity in lateral flow assays

VIEW, EarlyView.
Lateral flow assays (LFAs) are essential for cost‐effective, rapid point‐of‐care diagnostics. However, conventional colourimetric LFAs often lack the sensitivity required for low‐abundance biomarkers. This review evaluates six enhancement strategies: flow modulation, sample preconcentration, advanced reporters, chemical signal amplification, structural
