Summary: The study successfully measured the Gibbs energy of transfer of silver ions in different solvents using an ideal ionic liquid salt bridge, establishing a consistent data set and laying the foundation for the experimental thermodynamic framework of ion solvation chemistry. By defining solvent-independent indicators, comparison of electronating potential of redox systems was achieved, unifying the redox potential scales of all conventional solvents.

Summary: The AMOEBA+ water model has been extended to include alkali metal and halogen ions, improving the classical force field for molecular interactions. By using various quantum chemical data and experimental ion interactions, the model demonstrates enhanced accuracy in capturing ion properties. The energy components provided by AMOEBA+ are consistent with ab initio energy decomposition, making it a valuable tool for interpreting intermolecular forces in classical simulations.

Summary: The Gibbs free energy minimization approach provides a general framework for thermodynamic equilibrium analysis of gas mixtures, allowing for simultaneous reaction and phase equilibrium studies. Two theorems ensure globally optimal equilibrium results, quantifying the equilibrium behavior under different temperature and pressure conditions.

Summary: We propose a unified redox potential scale E-abs(H2O) that is valid for all solvents. Using potentiometric measurements on silver and chloride ions, we demonstrate that a salt bridge filled with the ionic liquid [N-2225][NTf2] satisfies the necessary conditions for determining single ion Gibbs transfer energy between different solvents. Based on these measurements, we develop a consistent unified redox potential scale E-abs(H2O) that allows for the assessment and comparison of redox potentials in six different solvents.

Summary: Understanding ion transport in solid materials is crucial for the design of electrochemical devices. This study focuses on investigating ion transport across atomically thin structures using a host-guest hybrid redox material based on polyoxometalates (POMs) encapsulated within single-walled carbon nanotubes (SWNTs). The nanotube sidewall acts as a barrier between the redox-active molecules and bulk electrolytes, allowing for the characterization of ion transport through electrochemical methods. The findings highlight the importance of the nature of the cation in the supporting electrolyte and the role of proton transport in the redox chemistry of nanoconfined redox materials.

Summary: This study investigated the thermodynamics of oxidative steam-reforming of pyrolysis volatile streams and evaluated the combined effects of temperature, steam to feedstock ratio, and oxygen content on the reaction. The steam partial pressure was found to be the most influential parameter, impacting hydrogen production and energy requirements significantly.

Summary: The research reveals that the stacking of dye molecules inside semiconducting chirality-sorted SWCNTs with diameters ranging from 1.15 to 1.5 nm affects their optical properties, and different SWCNT diameters and chiralities also result in changes in the absorption wavelength of the dye molecules.

Summary: In this study, A-site cation engineering was used to regulate the ionic migration and carrier transport capacity of low-dimensional bismuth-based hybrid perovskites. The use of BZA and 3-AMP improved the charge transport performance by reducing the distance between adjacent Bi-I octahedrons.

Summary: Polyoxometalates (POMs) show promise for molecular electronic applications due to their inorganic nature, ease of synthesis, and redox activity. Transport properties in POM junctions are not only influenced by the contact geometry and electronic structure of the molecule, but also by the presence of ions, which significantly impact the performance of nanoscale molecular electronic devices.

Summary: This study explores the jamming density of soil with strong dispersity by introducing excess volume-potentials and a mathematical model based on the second law of equilibrium in thermodynamics. The approach is validated using experimental results and aims to provide a deeper understanding of the link between jamming density, packing dispersity, and the second law of thermodynamics.

Summary: Through molecular dynamics simulations, we found that the ICT and CTC polymorphs in F(4)TCNQ-doped P3HT have similar thermodynamic stabilities, but the barrier to create the ICT polymorph is lower. The simulations also show that the activation barrier for converting the CTC polymorph to the ICT polymorph is relatively low.

Summary: The dimensional effect of semiconductor nanostructures on heterostructures was investigated, specifically focusing on the contact interface type and the number of electron transfer channels. Heterostructures were designed by combining a component with fixed dimension (2D g- C3N4) and a component with variable dimension (0D ZnO, 1D ZnO, 2D ZnO, and 3D ZnO). The accuracy of the structure was confirmed through various analyzes, and the charge transfer efficiency and photocatalytic properties were explored. The results showed that heterostructures with larger interface area created more electron transfer channels and exhibited higher charge transfer efficiency.
