Engineering an Artificial Metalloenzyme for Efficient Photo‐Enzymatic CO2 Conversion
Advanced Science, EarlyView.We built a light‐driven artificial metalloenzyme by covalently conjugating formate dehydrogenase (FDH) with a tailored rhodium complex (Rh‐L6) to overcome spatial‐separation‐limited electron transfer. This integration boosts NADH regeneration and CO2 conversion, giving 2.31‐fold higher formate yield than physical mixtures, due to a narrowed bandgap and

Advanced Energy Materials, EarlyView.A coaxial, membrane‐integrated hollow fiber electrode assembly (HFEA) is developed for continuous marine carbon mineralization. By utilizing a sub‐millimeter inter‐electrode gap, the HFEA minimizes Ohmic losses, achieving 50% energy reduction and over 85% DIC removal.

Membrane‐aided simultaneous reaction–separation for liquid phase products
AIChE Journal, EarlyView.Abstract Conventionally, reaction and separation are conducted as separate steps in liquid‐phase manufacturing, with products formed during reaction and subsequently separated from unreacted reagents, solvents, and byproducts. Integrating these steps into a simultaneous reaction–separation process can improve efficiency and reduce costs.

How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39
AIChE Journal, EarlyView.Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.

Modelling of Severe Accident and In-Vessel Melt Retention Possibilities in BWR Type Reactor
Science and Technology of Nuclear Installations, 2018 One of the severe accident management strategies for nuclear reactors is the melted corium retention inside the reactor pressure vessel. The work presented in this article investigates the application of in-vessel retention (IVR) severe accident ...
