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,

The Role of Operating Temperature on Pore‐Scale Gas Transport in Polymer Electrolyte Membrane Electrolyzers

Advanced Science, EarlyView.
This study clarifies the critical relationship between operating temperature and two‐phase flow behavior in polymer electrolyte membrane (PEM) electrolyzers by investigating pore‐scale gas bubble transport in the anode porous transport layer. Higher temperatures (80 °C vs 40 °C) result in a lower total bubble volume fraction and smaller bubble ...

Sacrificial Template‐Derived CoMo‐LDH Gas Diffusion Electrode for Anion Exchange Membrane Water Electrolysis

Advanced Science, EarlyView.
This work presents high‐performance CoMo‐LDH electrodes for anion exchange membrane water electrolysis (AEMWE), developed via a sacrificial template method. High‐valence Mo induces oxygen vacancies and drives the lattice oxygen mechanism (LOM). In alkaline media, Mo leaches, forming active (oxy)hydroxide.

CuCo‐Layered Double Hydroxide Nanosheets Grown on Hierarchical Carbonized Wood as Bifunctional Electrode for Supercapacitor and Hydrogen Evolution Reaction

Advanced Science, EarlyView.
The N/P co‐doped carbonized wood (NPCW) with open channels is used as the carrier, and in situ uniformly grown copper nanoparticles (Cu NPs) as nucleation centers to induce the vertical growth of CuCo‐LDH nanosheets along the substrate, forming a “carbon‐metal‐LDH” tertiary conductive network, which realizes the synergistic enhancement of high ...

High Oxidation State V‐O‐Co Structure Promotes the Role of V‐*O Intermediates in Efficient HMF Oxidation

Advanced Science, EarlyView.
By designing a high oxidation state VH‐O‐CoH structure, the V‐*O intermediate can be effectively generated, thereby facilitating the catalytic oxidation of HMF. This innovative design strategy demonstrates broad applicability, as it not only enables the formation of the active intermediate in various materials (V‐Ni2P), but also facilitates its ...

Rapid Charge Extraction via Hole and Electron Transfer Layers on Cu2O Photocathode for Stable and Efficient Photoelectrochemical Water Reduction

Advanced Science, EarlyView.
A simple strategy is developed to construct a unique “sandwich” structure of FeOOH/Cu2O/ZnO composite photocathode. FeOOH as HTL and ZnO as ETL promote the separation of photon‐generated carriers, reduce reaction energy barrier, and enhance the HER kinetic.
