Summary: Element mobility is crucial in geological processes, and understanding how elements migrate in minerals is essential for geochemical and geochronological applications. This study investigates the trace-element composition of dislocations on twin boundaries in rutile using atom probe tomography and transmission electron microscopy. The findings reveal that dislocations in rutile can act as both fast-diffusion pathways and traps for trace elements.

Summary: The research found that high pressure torsion processing can lead to the formation of a nanocrystalline structure in the Al3Ca2La1.5Mn alloy, significantly increasing the microhardness of the alloy. After annealing treatment, the microhardness of the alloy further increases, attributed to precipitation hardening resulting from the decomposition of the calcium and manganese supersaturated aluminum solid solution.

Summary: This study synthesized a near-infrared (NIR) Cys-special probe (MCyA) that could precisely and quickly detect Cys activity. The observations showed that the endogenous Cys activity was depressed under oxidative stress, but dramatically increased with omeprazole stimulation in HepG2 cells. MCyA was also successfully used to image the upregulation of Cys level in HepG2 cells in the presence of methionine (Met). Overall, MCyA is a novel and practical tool to study Cys-related physiological and pathological processes.

Summary: Sustainable battery concepts are crucial for future energy storage needs. Organic batteries based on redox-active polymers, when combined with environmentally friendly and safe electrolytes, show promise as a storage system. Deep Eutectic Solvents (DESs) are sustainable electrolytes with low environmental impact and high electrochemical stability. This study presents the first all-organic battery cell based on a DES electrolyte, demonstrating high Coulombic efficiency and stability.

Summary: The ability of deep eutectic solvents (DES) to enhance solubility of poorly soluble drugs has attracted attention. This study proposes a new existence state of drugs in DES - a quasi-two-phase colloidal system. Experiments show that drugs can form stable colloids in DES, which have superior physical and chemical stability compared to true solutions.

Summary: In this study, a series of acrylic PILs with imidazolium cations and bis(trifluoromethanesulfonyl)imide (TFSI) anions were synthesized, and the dynamic properties and molecular weight dependence of center-of-mass chain diffusion were investigated. It was found that the molecular weight dependence of center-of-mass diffusion is not affected by electrostatic interactions of IL groups within the studied range.

Summary: This study focuses on using focused laser differential interferometry (FLDI) to measure freestream density fluctuations. A comparison is made between FLDI measurements and pitot-probe measurements, with both converted to freestream pressure fluctuation spectra. The results show that FLDI can provide accurate quantitative data and extend the spectra beyond the pitot bandwidth.

Summary: The medium entropy alloy Al0.75CrFeNi2.1 with hypo-eutectic composition was processed by laser powder bed fusion (LPBF). Non-equilibrium solidification conditions led to the formation of cellular and lamellar microstructures. In-situ high-energy synchrotron X-ray diffraction (HEXRD) and atom probe tomography (APT) were used to study the microstructure evolution during post-build annealing. The mechanical properties of the alloy, including tensile strength and elongation at fracture, were evaluated and compared to martensitic steels.

Summary: In this study, the radial dependence of the inertial and dissipation range indices, as well as the spectral break separating the inertial and dissipation range in power density spectra of interplanetary magnetic field fluctuations, was examined using Parker Solar Probe data. The results showed that the inertial scale power-law index had a very weak radial dependence, possibly becoming steeper closer to the Sun. The dissipation range power-law index, however, had a clear dependence on radial distance, decreasing as the distance to the Sun decreased.

Summary: In this study, a new chemosensor MMN was designed and synthesized for monitoring pH and isoxaflutole. The results showed that MMN exhibited excellent stability and a clear fluorescence response to pH changes. It could selectively locate lysosomes in live cells and successfully detect H+ on test papers. Moreover, MMN specifically recognized isoxaflutole at a low detection limit. These findings suggest that MMN could be a potential chemosensor for pH and isoxaflutole detection in real samples.

Summary: Liquid-liquid phase separation (LLPS) in biomolecular condensates is influenced by electrostatic interactions and the dielectric environment. Simulations suggest that the presence of dielectric heterogeneity in condensed phases may only slightly enhance overall LLPS propensity. Theoretical treatments also indicate a partial compensation between solvent-mediated interactions and polyampholyte-solvent interactions.

Summary: This study investigates the collective single-particle reorientational relaxations and H-bond dynamics of acetamide in deep eutectic solvents through temperature-dependent dielectric relaxation measurements and molecular dynamics simulations. The results suggest a strong connection between the measured dielectric relaxation and simulated dynamics, showing significant microheterogeneity in these media. Additionally, a translation-rotation decoupling between the simulated reorientation and center-of-mass diffusion times is observed.

Summary: A theory for sequence-dependent liquid-liquid phase separation (LLPS) of intrinsically disordered proteins (IDPs) is developed, taking into account the effects of short-range, hydrophobic-like interactions and long-range electrostatics. The theory provides a general approach to understanding biomolecular condensates and has been verified through simulations.

Summary: Research indicates that in a system containing two intrinsically disordered protein (IDP) species, a substantial polymer excluded volume and a significant mismatch of the IDP sequence charge patterns can act in concert to demix the two IDP species upon condensation, revealing an energetic-geometric interplay in a stochastic, fuzzy molecular recognition mechanism that may facilitate subcompartmentalization of membraneless organelles.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.

Summary: Drug-loaded cellulose diacetate (CDA) membranes were prepared using different compositions of mixed solvent. The microstructure and performance of the membranes were investigated, and a method to predict drug release properties was proposed. The results showed that the composition of the mixed solvent significantly affected the overall performance of CDA membranes, and the release rates of drugs were related to Δdelta and the intrinsic viscosity of CDA.
