A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Speciation, Structural Refinement, and Distribution of Ti Sites in Titanium Silicalite‐1 From 47/49Ti NMR Crystallography at 28.2 Tesla

Angewandte Chemie, EarlyView.
Titanium silicalite‐1 (TS‐1), used in industrial selective oxidation processes, depends on specific, yet still unresolved Ti sites, dispersed within the framework of an MFI‐zeolite. Applying high field (28.2 T) 47/49Ti NMR and 17O NMR spectroscopy for an array of TS‐1 catalysts enables the development of an NMR crystallography protocol and the ...

Quasi-chemical approximation for polyatomic mixtures

, 2016
The statistical thermodynamics of binary mixtures of polyatomic species was developed on a generalization in the spirit of the lattice-gas model and the quasi-chemical approximation (QCA).

Selective Conversion of Polyolefin Waste to Branched Alkanes via Methane‐Free Tandem Hydrocracking–Isomerization

Advanced Science, EarlyView.
Scheme illustrating the selective conversion of plastic waste to isomerized C4‐C12 products using RuSZ1 under different reaction conditions. ABSTRACT In recent years, catalytic hydrocracking has emerged as a promising waste‐to‐feedstock solution for processing plastic waste.

Ammonia‐Induced Metal–Organic Framework Membrane Pore Tuning for Hydrogen Separation

Angewandte Chemie, EarlyView.
Impurity‐enabled pore tuning is achieved by harnessing trace ammonia, typically regarded as a harmful contaminant, as a reactive agent to modulate the surface structure and flexibility of ZIF‐8 membranes. Ammonia exposure induces partial surface amorphization and local rigidification, shifting the transport mechanism from a flexible to an intrinsic gas‐

From Pores to Pavement: Advanced Modeling of Aluminosilicates for Scalable Carbon Capture in Concrete

Advanced Science, EarlyView.
This study presents a transferable modeling framework for carbon capture using aluminosilicates, integrating Universal Isotherm Modeling with experimental data. It reveals how ultramicropores, alumina content, and amine functionalization influence CO2 adsorption energetics.

Diffusion of a hydrocarbon mixture in a one-dimensional zeolite channel: an exclusion model approach

, 2009
Zeolite channels can be used as effective hydrocarbon traps. Earlier experiments (Czaplewski {\sl et al.}, 2002) show that the presence of large aromatic molecules (toluene) block the diffusion of light hydrocarbon molecules (propane) inside the narrow ...

Hemicellulose hydrolysis catalysed by solid acids [PDF]

, 2013
Depolymerising hemicellulose into platform sugar molecules is a key step in developing the concept of an integrated biorefinery. This reaction is traditionally catalysed by either enzymes or homogeneous mineral acids.

Ligand‐Induced Electronic Response Enables Predictive QM/MM Simulations

Advanced Science, EarlyView.
Quantum mechanics/molecular mechanics (QM/MM) simulations are powerful tools for modeling complex molecular systems; however, their predictability has been constrained by the ambiguous definition of the QM region. An electronically informed protocol is introduced that defines QM regions by quantifying guest‐induced orbital shifts and charge ...
