Catalytic Hydrothermal Liquefaction of Polyethylene With Pt/C to Tune Product Selectivity

CleanMat, EarlyView.
Pt/C‐catalyzed hydrothermal liquefaction of polyethylene in supercritical water enables time‐dependent control of product selectivity, producing paraffin‐rich oils at shorter reaction times and aromatic‐enriched products at longer times without external hydrogen. ABSTRACT Hydrothermal liquefaction (HTL) represents a promising thermochemical pathway for

Unprecedented Wall‐Atomically Thick Bi5O7Br Nanotubes Embedding Abundant Bi Nanodots Boosting Efficiently Photothermal Coupling Catalytic CO2 Conversion

EcoEnergy, EarlyView.
Atomically thin Bi5O7Br nanotubes embedded with abundant Bi nanodots were constructed as an efficient photothermal catalyst for CO2 conversion. The localized surface plasmon resonance and photothermal effect of Bi nanodots synergistically enhance light harvesting, charge utilization, and reaction kinetics, resulting in significantly improved CO2 to CO ...

Ceria Nanostructures Obtained by Hydrothermal Synthesis: Exploring the Experimental Parameter Landscape for Precise Morphology and Size Control

European Journal of Inorganic Chemistry, EarlyView.
Hydrothermal and microwave‐assisted syntheses enable systematic tuning of ceria nanostructure morphology. Chloride counter‐ions direct nanorod growth, while an acetate buffer yields uniform nanocubes whose size (14–26 nm) is tuned via the reactor filling ratio, with microwave heating significantly cutting reaction times to minutes while preserving high

Removal of pharmaceuticals from municipal wastewater using a powdered activated carbon‐supplemented moving bed membrane bioreactor

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The new European Union Wastewater Directive 2024/3019 requires upgrading sewage treatment plants to achieve 80% removal of micropollutants. This study aimed to compare different Powdered Activated Carbon dosing strategies within a hybrid Moving Bed‐Membrane Bioreactor (PAC‐MB‐MBR) system, to evaluate its performance and to study the

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Influence of Strain Rate on the Strain Hardening Behavior of a Lean Duplex Stainless Steel

MetalMat, EarlyView.
The aim of this study was to examine how strain rate influences the compressive strain‐hardening behavior of a lean duplex stainless steel LDX 2101. Microstructural analysis using electron backscatter diffraction (EBSD) revealed a strain‐induced austenite‐to‐martensite transformation.
