Summary: The study utilized a dual fluorescent molecular probe to monitor nanoscale dynamics in polystyrenes, revealing that planarization of the molecule in the excited state only occurs when a large polymer free volume is available nearby, lasting on average 1.2 seconds. This investigation provides insights into the dynamics of molecular environments through statistical analysis and computational simulations.

Summary: This study explores the temperature dependence of the structural relaxation time in glass-forming materials and aims to find a unified description. Both the string model and the localization model are examined and found to describe the relaxation behavior well. By comparing the model parameters, a connection between the local caging scale and the entropy of activation for molecular rearrangements in the string model is established.

Summary: Biomolecular condensates driven by liquid-liquid phase separation (LLPS) have been investigated as novel activity regulators of living organisms. However, whether membrane wetting can regulate LLPS has remained unexplored. In this study, the researchers demonstrate that membrane wetting can indeed regulate LLPS in cell-sized spaces and alter the equilibrium state. They also explain the space-size-dependent LLPS from the higher wettability of certain biomolecules. These findings suggest that LLPS can be regulated by cell-sized confinement and competition for membrane wettability, making it a feasible principle in living cells.

Summary: We investigate the origin of density depletion and enhanced density fluctuations in water near an extended hydrophobic solute. We argue that both phenomena are remnants of the critical drying surface phase transition that occurs at liquid-vapor coexistence. The results provide a firm physical basis for understanding water behavior near hydrophobic solutes.

Summary: In this study, we focused on the enhanced fluctuations near the pseudocritical point in QCD systems and how they modify transport coefficients, as well as made a phenomenological estimate for soft pion momentum spectrum. By formulating appropriate hydrodynamic equations near the O(4) critical point and determining correlation functions, we were able to analyze the scaling behavior and estimate critical fluctuations. The calculated pion dispersion curve helped us estimate the expected enhancement of soft pion yields, providing a plausible explanation for experimental observations.

Summary: Cell heterogeneity is crucial for understanding complex biomedical issues. Trajectory inference-based approaches are tools developed for analyzing single-cell transcriptomics data, which aim to reconstruct evolving pathways from different cell states. This concept can be extended to Raman spectroscopy to study the dynamics of adipocyte differentiation.

Summary: This study establishes a theoretical framework and methodology for determining the dynamic modulus of interfacial regions in biocomposites, which is crucial for understanding the structure-function relationships in various load-bearing biological materials. The approach is applicable to a wide range of biocomposites in natural materials and can be adapted into similar composite systems in different fields like architected nanocomposites and bioinspired materials.

Summary: It is demonstrated that the freezing density scaling of transport coefficients in fluids, similar to the freezing temperature scaling, can be explained by the quasi-universal excess entropy scaling approach proposed by Rosenfeld. This scaling approach for freezing density has a considerably wider applicability on the phase diagram of Lennard-Jones and related systems. The excellent accuracy of this approach in reproducing the shear viscosity coefficients of saturated liquid argon, krypton, xenon, and methane further showcases its predictive power.

Summary: This study developed a new analysis method for identifying dynamic heterogeneity in a better way. The analysis selectively probed different diffussion time-regimes in a heterogeneous system from a single measurement and observed their temperature evolution. The temperature dependent translational diffusion of a fluorophore was studied using fluorescence correlation spectroscopy. The results suggest that the difference in the extent of viscosity decoupling for different diffusion time-regimes might be a better criteria to identify dynamic heterogeneity.

Summary: Accurate understanding of the chemistry of solid-electrolyte interphase (SEI) is crucial for developing new electrolytes for high-energy batteries with lithium metal (Li-0) anodes. Our study reveals a more complex formation mechanism of SEI, involving reactions between Li-0 and electrolyte, as well as contributions from cathode, moisture, and native surface species on Li-0, with dynamic changes during cycling.

Summary: Coal permeability is influenced by the pore structure. This study reveals the multiscale flow mechanism of methane in coal and proposes a mathematical model to describe it. The results show that micro-nanopore radius and number of connected pore series are crucial for determining coal permeability.

Summary: This work analyzes the mean collision force of a small classical particle moving through rarefied gases by directly calculating the decrease of particle's velocity due to elastic collisions. The study provides a self-consistent solution for the mean collision force in Maxwell gas and compares it with the Stokes force. It is found that the friction force in rarefied gases exhibits a quadratic speed dependence at high speeds, unlike the linear speed dependence of the Stokes force.

Summary: A NiAl alloy/Ni3Al-based superalloy diffusion couple with an electroplated NiRe layer was prepared and analyzed for its high-temperature interdiffusion performance at 1100 degrees C under argon atmosphere. A Re-based diffusion barrier was formed during the diffusion process, which alleviated the microstructural instability of the superalloy. The chemical diffusion coefficient of Al was significantly reduced by the Re-based diffusion barrier.

Summary: The study focused on the chemically controllable triggering of single-virus fusion within endosomes. The results showed that endosomal curvature did not significantly affect fusion kinetics, indicating that membrane deformability may play a more crucial role in viral entry. This study provides insights into how cellular restriction factors and altered endosomal trafficking affect viral membrane fusion.
