Predicting Liquid Organic Hydrogen Carrier Saturation in Dehydrogenation Cell Gas Diffusion Layers for Hydrogen Storage

ChemCatChem, EarlyView.
The influence of gas diffusion layer (GDL) microstructures on mass transport and methylcyclohexane saturation (MCH) in a dehydrogenation cell was investigated using pore network modeling. We reveal that GDLs with larger pore diameters (dpore) and lower tortuosity (τ) enable enhanced MCH invasion, thereby improving reactant concentration at the catalyst.

Hybrid Polarizing Solids with Extended Pore Diameters for Dissolution Dynamic Nuclear Polarization

Chemistry–Methods, Volume 5, Issue 6, June 2025.
Versatile and easily filtrable hyperpolarizing solids are introduced, used to generate pure hyperpolarized solutions by dissolution dynamic nuclear polarization (dDNP) for nuclear magnetic resonance spectroscopy (NMR), compatible with virtually any existing polarizer.

Boundary conditions and universal finite‐size scaling for the hierarchical |φ|4$|\varphi |^4$ model in dimensions 4 and higher

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

Evaluating the Resilience of ESG Investments in European Markets During Turmoil Periods

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates the resilience of Environmental, Social, and Governance (ESG) investments during periods of financial instability, comparing them with traditional equity indices of the three largest economies in the European Union by gross domestic product: Germany, France, and Italy.

Aminosulfonated Graphene as a Catalyst for Efficient Production of Biodiesel from Fatty Acids and Crude Vegetable Oils

ChemSusChem, EarlyView.
The covalent integration of amino and sulfonate groups on the graphene surface significantly enhances activity in acid‐catalyzed reactions, such as in biodiesel production and dehydration of saccharides. Developing such heterogeneous, recyclable catalysts is vital, as acid catalysis represents one of the most general and versatile strategies in organic

All Electrochemical Synthesis of Performic Acid Starting from CO2, O2, and H2O

ChemSusChem, EarlyView.
The first all‐electrochemical synthesis of performic acid starting from CO2, O2, and H2O has been achieved in a two‐step process using gas diffusion electrodes. Therefore, the electrochemical CO2 reduction reaction (eCO2RR) to formate was coupled to the electrochemical O2 reduction reaction (eCO2RR) to H2O2 without downstream processing.

AGORA: Adaptive Generation of Orthogonal Rational Approximations for Frequency‐Response Data

International Journal of Circuit Theory and Applications, EarlyView.
This paper introduces the adaptive generation of orthogonal rational approximations (AGORA) method for rational function approximation of measured or simulated microwave network parameters. AGORA allows estimating the model order for a given error tolerance and does not require any initial estimates or adjustment of hyperparameters. ABSTRACT This paper

On the Density–Density Correlations of the Non‐Interacting Finite Temperature Electron Gas

Contributions to Plasma Physics, EarlyView.
ABSTRACT The density–density correlations of the non‐interacting finite temperature electron gas are discussed in detail. Starting from the ideal linear density response function and utilizing general relations from linear response theory, known and novel expressions are derived for the pair correlation function, static structure factor, dynamic ...

Non‐Markovian Quantum Kinetic Simulations of Uniform Dense Plasmas: Mitigating the Aliasing Problem

Contributions to Plasma Physics, EarlyView.
ABSTRACT Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau, or Balescu–Lenard equation. However, these equations do not properly take into account correlation effects, which require the use of generalized non‐Markovian kinetic equations.

Creep properties and constitutive model of diabase in deep water conveyance tunnels

Deep Underground Science and Engineering, EarlyView.
The axial and lateral creep characteristics of diabase were analyzed based on compression creep tests. The nonlinear viscoelastic‐plastic model capable of describing the whole creep process was established based on the fractional derivative and damage theories.
