Summary: The theoretical study investigates the adsorption behavior of a single AB random copolymer chain onto homogeneous and inhomogeneous ab surfaces with regular periodic patterns. The study employs the Morita approximation for averaging over disorder in the copolymer sequence and proposes a general scheme for constructing the Morita approximation. The adsorption characteristics and accuracy of the Morita approximation are assessed for different scenarios, and it is found that higher orders of the approximation are required for non-adsorbing B blocks repelled from the surface and for periodically inhomogeneous surfaces.

Summary: This study focuses on the spatial distribution and dispersion of charged nanoparticles in near-surface shear flows under the influence of electrostatic repulsion and absorption. By varying electrolyte concentrations, the electrostatic repulsion between particles and the charged surface can be adjusted. The particles leaving the field of vision are excluded from further analysis, making the experimental ensemble equivalent to Taylor dispersion with absorption. These two factors significantly modify the particle distribution and lead to a tenfold reduction in the spreading dynamics compared to the noninteracting case.

Summary: The study found that the alteration of charge distribution due to different PE chain structures directly affects the adsorption behavior of PEs on an oppositely charged surface. In a salt-free system, PE chain structure and sequence variables have a significant impact on adsorption behaviors, showing complex behaviors in adsorption amounts. Additionally, overcharging only occurs when the bare surface charge density is low enough.

Summary: In recent years, the D-A covalent organic frameworks (COFs) have been studied for their potential applications in photocatalysis, specifically for the removal of uranium (U(VI)) from wastewater. Three 2D COFs materials (Tp-Tapb, Tp-Taz, and TpTt) with similar structures but different building monomers and acceptor distances were synthesized and compared for their photocatalytic performance and U(VI) removal efficiency. TpTt showed the best performance, attributed to the coexistence of triazine and ketone groups and its high content of heteroatoms.

Summary: We utilized classical Density Functional Theory (cDFT) and Monte Carlo simulations to investigate the interaction between heterogeneously charged surfaces in an electrolyte solution. Our study showed consistent behavior between cDFT and Monte Carlo simulations in terms of force curves and two-dimensional density profiles. By using the validated cDFT, we explored the effects of challenging-to-simulate parameters on the system's behavior, including domain size, domain charge, domain charge configuration, and bulk electrolyte concentration. Notably, the force curve was found to be more sensitive to domain size in an asymmetric configuration, while the bulk concentration had a weak influence on the force curve regardless of the system's configurations.

Summary: We study the effects of randomly distributed diffusivities and speeds in two models for active particle dynamics. We find that non-Gaussian displacement distributions, including Cauchy-type and exponential shapes, emerge in these models in the long time limit. The resulting shapes of the displacement distributions with distributed diffusivities for the active models are in striking contrast to passive diffusion models. Additionally, we demonstrate that the case with active-noise agrees well with measured data for the displacement distribution of social amoeba.

Summary: We present a refined approach to explore complex networks with stochastic resetting based on node centrality measures. This approach allows a random walker to jump not only to a deliberately chosen resetting node, but also to a node that can reach all other nodes faster. By considering the resetting site as the geometric center, we calculate the Global Mean First Passage Time (GMFPT) using Markov chain theory to determine the search performance of the random walk with resetting. We compare different nodes as resetting sites by comparing their GMFPT values.

Summary: Ion mobility mass spectrometry (IM-MS) techniques are valuable for structural characterization of biomolecular systems. However, interpreting IM-MS data is often challenging due to conformational isomerism. To address this, we developed MassCCS, an open-source code that computes the collision cross-section (CCS) of molecules using atomic and molecular buffer gas particles. MassCCS is highly accurate and efficient, especially for large macromolecular assemblies. Extensive tests showed its reliability, scalability, and performance. The code is freely available at https://github.com/cces-cepid/massccs.

Summary: This article examines the transport of diffusive particles switching between mobile and immobile states with finite rates. The study focuses on the impact of advection on density functions and mean squared displacements (MSDs). Significant anomalous diffusion with cubic scaling in time of the MSD is found at intermediate time scales for high Peclet numbers. This cubic scaling is present for both short and long mean residence times in the immobile state. The study also reveals the newly observed phenomenon of advection-induced subdiffusion for immobilized tracers in the presence of high Peclet numbers. Additionally, the effective advection velocity is reduced in the long-time limit, while the MSD is enhanced by advection. The physical mechanisms behind the emergence of non-Gaussian density functions and the characteristics of the MSD are explored.

Summary: In this study, we investigate the overdamped dynamics of various stochastic processes under confinement of an harmonic potential. We analyze the impact of both static and dynamic noise on the dynamics of pure processes and find that noise poses challenges for process inference. We observe that static noise leads to subdiffusive behavior, while dynamic noise results in superdiffusive behavior.

Summary: Detailed knowledge of individual income dynamics is crucial for investigating the existence of the American dream and understanding the potential for improving income during one's working life. This study develops a framework that disaggregates the temporal properties of income at the individual level, overcoming the limitations of previous methods that rely on transition matrices. The framework, based on the concept of First Passage Time in a stochastic process, provides improved and more granular estimates of income dynamics. The results contribute to our understanding of income dynamics in real economies and offer tools for policy interventions.

Summary: We introduce a stochastic process called incremental multifractional Brownian motion (IMFBM), which behaves locally like fractional Brownian motion with varying Hurst exponent and diffusivity. We derive formulas for the mean squared displacement and correlations of IMFBM, which are simple and elementary. We also provide simulation comparisons and estimation methods for IMFBM. This mathematically simple process is valuable in understanding anomalous diffusion dynamics in changing environments, such as viscoelastic systems or actively moving particles.

Summary: Stochastic resetting is a rapidly developing topic that studies the occasional reset of a diffusing particle to its starting point and its effects on optimal first-passage times to a target. The concept of partial resetting has been established and analyzed, and here we further develop a technique to determine the time-dependent probability density function (PDF) for Markov processes with partial resetting. We obtain an exact representation of the PDF for general symmetric Lévy flights with stable index 0 < a ≤ 2, and for Cauchy and Brownian motions (a = 1, 2), the PDF can be expressed in terms of elementary functions in position space. We also determine the stationary PDF and observe intricate crossover behaviors as a function of time in our numerical analysis.

The results demonstrate that the integrodifferential operators with exponential and Mittag-Leffler kernels are not suitable for the physically relevant diffusion scenarios discussed, while the conformable and Caputo operators are more appropriate.

Summary: Using stochastic simulations and analytics, this study investigates the nonergodicity of box-confined fractional Brownian motion under both subdiffusive and superdiffusive Hurst exponents. It is observed that at H > 1/2, the non-equivalence between ensemble-averaged and time-averaged mean-squared displacements (TAMSDs) is most pronounced, with a wide range of individual TAMSDs at H -> 1, and two distinct short-lag-time TAMSD exponents.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
