Programmable Carrier‐Free All‐Enzyme Beads for Modular Continuous‐Flow Biocatalysis

open access: yesAdvanced Materials, EarlyView.
Genetically encoded enzyme building blocks self‐assemble into monodisperse, carrier‐free protein beads via a droplet‐based formulation strategy. These programmable catalytic particles enable modular continuous‐flow biocatalysis, from single‐enzyme reactions to multi‐enzyme cascades and bead–bead coupled reactor systems.

Interface‐Mediated Catalysis for Improved Hydrogen Storage in Reactive Hydride Composites

open access: yesAdvanced Materials, EarlyView.
Catalyst–hydride interfaces are engineered in Co@C‐ and Ni@C‐modified 2LiH + MgB2 reactive hydride composites to accelerate hydrogen uptake and release. Multiscale scattering, in‐situ synchrotron radiation powder x‐ray diffraction and density functional theory calculations reveal the structural and electronic origin of the catalytic enhancement ...

Numerical investigation of gas holdup and phase mixing in bubble column reactors

open access: yes, 2011
A discrete bubble model (DBM) has been used to study the overall gas holdup and the phase mixing in bubble column reactors. The Eulerian–Lagrangian approach has the advantage that it is possible to study the overall gas holdup and the gas phase mixing in

Gas Holdup in a Cocurrent Air-Water-Fiber Bubble Column [PDF]

open access: yes, 2004
Effects of superficial liquid velocity (Ul ), superficial gas velocity (Ug ), and fiber mass fraction (C) on gas holdup (ε) and flow regime transition are studied experimentally in well-mixed water-cellulose fiber suspensions in a cocurrent bubble column.

Surface Segregation in Compositionally Complex Ag‐Au‐Pd‐Pt Solid Solutions: Insights From High‐Throughput Experimentation and Atomistic Simulations

open access: yesAdvanced Materials Interfaces, EarlyView.
Surface segregation in quaternary Ag‐Au‐Pd‐Pt compositionally complex solid solutions is systematically mapped across 684 compositions by combining high‐throughput EDX and XPS characterization of co‐sputtered thin‐film libraries with large‐scale MD/MC atomistic simulations.
