Design and optimization of a catalytic membrane reactor for the direct synthesis of propylene oxide

, 2015
Using numerical simulations, a new membrane reactor is proposed for the direct synthesis of propylene oxide (PO) in liquid phase. The reactor is a combination of two consecutive catalytic reactor units, one for the hydrogen peroxide (H2O2) synthesis on a

Defect‐Engineered Microwave‐Responsive Ni@C Composites From Waste PET for Catalytic Plastic Upcycling

Advanced Materials, EarlyView.
A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain

Beyond Nanoporosity: A CO2‐Conditioned Glassy Matrix Contributes to the Brittle‐to‐Ductile Transition of Nanocellular Polyetherimide

Advanced Materials, EarlyView.
The mechanical performance of nanocellular polyetherimide cannot be explained by nanoporosity alone. It is shown that CO2 saturation and desorption leave a distinct mechanical signature in the glassy matrix before foaming. This matrix contribution provides a new route to understand and optimize the brittle to ductile transition in nanocellular polymers.

Hierarchical Flexible Ceramic Nanofiber Membrane for Simultaneous Membrane Distillation and Photocatalytic Hydrogen Evolution

Advanced Materials, EarlyView.
A hierarchical flexible ceramic nanofiber membrane integrates a La‐stabilized ZrO2 scaffold with superhydrophobic UiO‐66‐NH2/CdS heterojunctions. The gas–liquid–solid interfacial architecture sustains vapor‐selective desalination, visible‐light charge separation, and rapid H2 extraction, enabling simultaneous freshwater production and photocatalytic ...

Redox‐Confined Interfacial Polymerization Enables Mechanically Robust and Self‐Adhesive Nanofilms

Advanced Materials Interfaces, EarlyView.
Redox‐confined polymerization of a simple thiol monomer at a water‐organic interface generates robust freestanding films with nanoscale thickness. The resulting disulfide‐crosslinked nanofilms combine high stiffness with intrinsic adhesion to soft substrates, enabling conformal contact with artificial skin without additional functionalization.

UCST‐Responsive PMEGA: From Solution Behavior to Functional Hydrogel Surfaces

Advanced Materials Interfaces, EarlyView.
PMEGA is used as a versatile water‐based UCST‐responsive platform for engineering microstructured hydrogel coatings via a thiol–ene CLAG approach. From PMEGAs of well‐defined UCST properties, the UV‐based CLAG method provides precise control over film thickness, ranging from nanometers to micrometers, and enables high‐resolution patterning.
