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.

Catalytic Strategies for Amide‐Based Michael Additions: Advances and Perspectives

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
The Michael addition is a cornerstone transformation in organic synthesis, enabling efficient C–C and C–heteroatom bond formation. Traditionally, α,β‐unsaturated carbonyl compounds such as enones and esters have dominated as Michael acceptors, whereas α,β‐unsaturated amides remain underutilized due to their strong resonance stabilization and low ...

Diethyl 2-(acridin-9-ylmethylene)malonate

open access: yesActa Crystallographica Section E Structure Reports Online, 2001
The title compound, C21H19NO4, (II), is an acridine derivative with an angle of 68.30 (2)° between the aromatic ring system and the ethyl­ene moiety. It is remarkable that (II) is isostructural with diethyl 2-(anthracen-9-yl­methyl­ene)­malonate, which bears a C atom at the position where in (II) an N atom is found.
