High‐Precision Silicon Microgrooves via Metal‐Assisted Chemical Etching (MACE) Using Electrospun Nanofibers

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
This paper presents a novel, low‐cost process for fabricating high‐precision silicon microstructures using an electrospun nanofiber mask. It details the dual functionality of the palladium (Pd) nanocluster mask, which acts as a catalyst for Metal‐Assisted Chemical Etching (MACE) in acidic solutions and as a porous protective layer in alkaline ...

An Efficient CO2‐Upcycling Platform Based on Engineered Halomonas TD with Enhanced Acetate‐Utilizing Capacity via Adaptive Laboratory Evolution

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
An electrochemical system is designed to convert CO2 into CO2‐derived electrolytes (CDE), mainly containing acetate and formate. The underlying mechanism of acetate metabolism in Halomonas TD80 is explored via ALE. Engineered TD80 produced high‐yield diversified products from CDE.
