Summary: In this study, a niobium-incorporated meso-tetra-(4-carboxyphenyl)-porphyrin complex was synthesized and grafted onto the surface of functionalized SBA-15. Both the homogeneous and heterogenized complexes showed good catalytic activity for the esterification of levulinic acid, producing methyl levulinate and alpha-angelica lactone as the main products under mild reaction conditions.

Summary: Many companies in the power transformer industry are exploring alternative drying methods to speed up the drying process of coatings while maintaining the same coating protection properties. This paper investigates the infrared drying of two solvent-borne coating systems, and finds that infrared technology notably reduces drying times and maintains or improves anticorrosion performance compared to coatings dried under atmospheric conditions.

Summary: In systems biology, the analysis of complex nonlinear systems faces challenges in terms of methodology. One major bottleneck is the lack of realistic test problems for evaluating and comparing computational methods. This study presents an approach for realistic simulation studies using time course data typically measured in systems biology. By utilizing published systems biology models with experimental data, the relationship between model features and measurement features is evaluated, enabling the suggestion of realistic simulation study designs and generation of simulated data for dynamic models. The approach is demonstrated and validated on multiple models, providing a valuable tool for the development of novel methods for dynamic modeling.

Summary: This study presents a novel implementation of the boundary element method for modeling multiple scattering of plasmonic nanowires. The model considers both local and nonlocal materials and the nonlocal hydrodynamic model is used to capture nonclassical effects of free electron motion in metals. The challenging aspect of the modeling lies in the different interface conditions required at the boundaries of various media. The proposed algorithm is capable of handling arbitrary geometries and material compositions, making it a comprehensive numerical tool for exploring nonlocal nanowires. The accuracy and agreement of the results obtained using the boundary element method are verified both quantitatively and qualitatively, demonstrating good performance in both near- and far-field regimes.

Summary: This study investigates the classification of solvent systems based on the dissolution behavior of cocrystals and explores the design of crystallization and cake washing steps. By comparing the solubilities of pure components, it is possible to determine the component that needs to be added in excess for thermodynamic stability of the cocrystal. Moreover, highly dissimilar solubilities of pure components can easily identify highly asymmetric phase diagrams that are not suitable for crystallization and cake washing purposes.

Summary: This paper proposes a mathematical model and calculation method for available supply capability (ASC) in distribution systems. The model considers all allowed load increments from the current operating point to the security boundary. The proposed method accurately evaluates the supply capability margin of a distribution system and provides operational guides. This work lays the foundation for the ASC theory in distribution systems, analogous to the ATC theory in transmission systems.

Summary: Recent research shows that the evolution of an isolated quantum system can be misinterpreted by an observer as pure dephasing phenomenon when using an imperfect clock. In the context of quantum transport, a stable probability current must be robust against any transformation that conforms with an ideal Gaussian stationary clock. This understanding has been numerically demonstrated in a topological insulator.

Summary: This study investigated the relationship between the solvent strength of organic phase and the partition coefficient in two biphasic solvent systems (HEMWat and EBuWat) using four retention models. The results showed that different models had varying fitting results in different systems. A mathematical relationship between the partition coefficient and solvent strength could be obtained, and a functional map was proposed to facilitate the selection of an optimal solvent system for separation. The successful separation of two components from Dendrobium officinale using high-speed countercurrent chromatography demonstrated the application of this new method.

Summary: Chemical systems typically exhibit strong nonlinear vibronic couplings at both zero and finite temperatures. The Davydov ansatz method, based on variational coherent states, is used to simulate quantum dynamics and spectroscopy. Two molecular systems, pyrazine and the 2-pyridone dimer, are studied as model systems, showing nontrivial quadratic vibronic couplings in different frequency regions. The method proves advantageous for nonlinear couplings, and squeezed bases are demonstrated to be applicable at finite temperatures using thermofield dynamics.
