Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry

Advanced Science, EarlyView.
The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

A Synergistic Complexation‐Encapsulation Paradigm Enables Unprecedented Radioactive Remediation

Advanced Science, EarlyView.
A novel HDEHP‐APG eutectic mixture‐based detergent is developed that achieves highly efficient decontamination of Am through a synergistic complexation‐encapsulation mechanism. Remarkably, such a detergent effectively removes radionuclides across a wide range of oxidation states (+I to +VII), demonstrating exceptional versatility.

Molecular Chain Elongation Mechanism for n‐Caproate Biosynthesis by Megasphaera Hexanoica

Advanced Science, EarlyView.
The medium‐chain carboxylate‐producing microbe Megasphaera hexanoica is analyzed through genomics, transcriptomics, and metabolic engineering. The n‐caproate biosynthetic pathway is reconstructed in Escherichia coli, highlighting MhTHL as a key β‐ketothiolase. Structural analysis and mutagenesis reveal that MhTHL has a distinct substrate‐binding pocket,
