Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

Advanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Plausibility of potassium ion-exchanged ZSM-5 as soot combustion catalysts

Scientific Reports, 2017
Potassium (K) ion-exchanged ZSM-5 zeolites were investigated for catalytic soot combustion. X-ray absorption fine-structure (XAFS), Raman, in situ IR and NH3-temperature programmed desorption (NH3-TPD) confirmed the location of K+ at the ion-exchanged ...

Quantifying Electron and Ion Transfers in Contact Electrification with Ionomers

Advanced Functional Materials, EarlyView.
The concurrent existence of both electron and ion transfers in solid‐ionomer contact electrification is reported. The ion transfer contributes significantly to the process of contact electrification, especially at high humidity, although only less than 2% of ions participate in the ion transfer, suggesting that there is room for further performance ...

Biomimetic synthesis of vesicular covalent organic frameworks by gemini surfactants for in-situ enzyme cascade immobilization

Nature Communications
In nature, enzymes in biofilms often lack robustness and chemical functionality. Covalent organic frameworks (COFs) have emerged as a robust platform for enzyme immobilization, but mimicking biofilm structures for in-situ enzyme immobilization remains ...

A Complementary Hole‐Transport Layer of PTAA and SAM on FTO Substrate for p‐i‐n Structured Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
The complementary roles of Poly[bis(4‐phenyl)(2,4,6‐trimethylphenyl)amine (PTAA) and self‐assembly monolayer (SAM) in a composite hole transport layer for rough fluorine‐doped tin oxide substrates are demonstrated, with PTAA preferentially depositing in the valleys and SAM occupying the peaks, resulting in improved surface potential uniformity ...

Selective Laser Sintering 3D Printing of Drug‐Loaded Intravitreal Implants

Advanced Functional Materials, EarlyView.
Selective laser sintering enables the fabrication of biodegradable and biocompatible intravitreal implants with tunable microstructures for sustained drug delivery. By modulating laser scanning speed, the polymer matrix architecture is engineered to control the release kinetics of dexamethasone and riboflavin over several months. This approach offers a

Optimization and Dynamic Adjustment of Tandem Columns for Separating an Ethylbenzene–Styrene Mixture Using a Multi-Objective Particle Swarm Algorithm

Separations
This study focuses on optimizing two tandem columns to separate ethylbenzene and styrene. A steady-state model is developed to minimize total energy consumption (TEC) and total annualized cost (TAC) by optimizing the reflux flow rates.
