Summary: This study reports the synthesis and characterization of hierarchical porous structure of polydimethylsiloxane (PDMS) sheets using a two-step phase separation synthesis protocol. Experimental results show that increasing the methanol/solvent ratio increases the concentration of large pores and decreases small pore density. Tensile testing results demonstrate that the synthesis protocol can control the porous structure with a wide range of flexibility while keeping the density constant.

Summary: A one-pot method was used to regulate the hydrated structure and wettability in a hierarchical porous hydrogel, resulting in optimized water bonding network in an evaporator for efficient solar-driven vapor generation. The hydrophobic walls of the air pores in the foam provide vaporization sites and reduce heat loss, while the hydrophilic skeleton with secondary pores effectively pumps capillary water. The proportion of intermediate water in the foam reaches 87.6%, contributing to exceptional evaporation rate and robust solar-driven vapor generation performances.

Summary: By adjusting the PLLA concentration and/or precipitation temperature, controllable microstructures and interconnected pore morphology of porous PLLA membranes can be easily achieved. The prepared PLLA membranes exhibit high crystallinity ranging from 61.8% to 75.8% and a greatly increased maximum water contact angle of 142.3 degrees. The membranes also demonstrate enhanced mechanical damage resistance, increased porosity up to 90.8%, and higher oil-absorption capacity at 24.1 g/g, showing great potential for application as a biodegradable oil-water separation material.

Summary: A strategy for preparing hierarchical porous carbons derived from biomass and urea with tunable pore size distribution was proposed for the adsorption and separation of light hydrocarbons from mixed gas. The increase in urea content led to narrower pore size distributions but decreased surface area and total pore volume of the porous carbons. Different combinations of porous carbons exhibited varying capacities and selectivities towards different light hydrocarbons.

Summary: Repulsive Bose-Bose mixtures are known to either mix or phase separate into pure components. Here, a mixed-bubble regime is predicted, where bubbles of the mixed phase coexist with a pure phase of one of the components. This effect arises due to unequal masses or unequal intraspecies coupling constants, resulting in a competition between the mean-field term and a nonquadratic beyond-mean-field correction. Parameters of the mixed-bubble regime in all dimensions are identified and implications for current experiments are discussed.

Summary: Hierarchical porous structures of Ni-3(CO3)(OH)(4) and (NixCo1-x)(6)(CO3)(2)(OH)(8) .H2O were synthesized via a hydrothermal route, with chloride ions playing a crucial role in the morphology of the (Ni,Co)(6)(CO3)(2)(OH)(8) .H2O structures. The electrochemical properties of the products were found to be influenced by their chemical composition and surface property, with Ni-3(CO3)(OH)(4) exhibiting higher specific capacitance but poorer rate performance and cycle stability compared to (Ni,Co)(6)(CO3)(2)(OH)(8) .H2O.

Summary: The concentration distribution of the deterrent in single-base propellant during firing is crucial for the ballistic properties of gun propellant. This study introduces an onion model combining molecular dynamics simulation and finite element method to accurately predict the concentration distribution and discover a new time scale for diffusion. Experimental validation using Raman spectroscopy confirms the correctness of the onion model. This work provides guidance for deterrent design and can be extended to diffusion in polymers with different crystallinity.

Summary: The development of high-performance supercapacitors relies on the effective utilization of pores for charge storage. However, quantitatively relating the porous structure to charging dynamics remains a challenge. In this study, we use a laminate-electrode model and an equivalent circuit model to characterize the relationship between the structure and charging dynamics of porous electrodes. We find that the charging dynamics of graphene-based supercapacitors are dominated by ion diffusion from the electrolyte region into the layered structure.

Summary: Aluminum-based lithium adsorbent (Li/Al-LDH) is the only industrialized adsorbent for Li+ extraction from salt lake brines. The declined Li+ adsorption performance in sulfate-type brines is explained by the replacement of interlayer Cl- with SO42-, which alters the stacking structure and interlayer spacing. The intercalated SO42- regulates Li+ adsorption of Li/Al-LDHs through expanded interlayers, close packing, and electrostatic repulsion.

Summary: This study revealed that cellular senescence is a major cause of imbalanced differentiation of bone marrow mesenchymal stem cells (BMSCs) and the progression of steroid-induced osteonecrosis of the femoral head (SONFH). MiR-601 and SIRT1 were identified to play important roles in BMSCs senescence, and metformin was shown to alleviate BMSCs senescence and SONFH progression. These findings provide a new perspective for the prevention and treatment of SONFH.

Summary: In this study, the influence of solvent on the structure and ionic screening of electrolytes under slit confinement and in contact with a reservoir was investigated using classical density functional theory. It was found that spatially resolving solvent molecules is essential for understanding the ion structure, excess ion adsorption, and pressure exerted on the walls. While there were only moderate differences observed in the pressure oscillations and decay lengths based on the ion diameter and Debye length, the crossover to the hard-core-dominated regime depended sensitively on the relative permittivity, ion concentration, and other factors.
