Summary: Super-resolution microscopy is used to investigate the internal structure of microgels and their response to temperature changes. The study combines direct stochastic optical reconstruction microscopy and molecular dynamics simulations to analyze the behavior of microgels on hydrophilic and hydrophobic surfaces. The results provide important insights for using this technique in studying more complex systems.

Summary: The simultaneous stabilization of water droplets in a highly non-polar oil phase using temperature responsive, soft and hydrophilic PNIPAM microgel particles and solid and hydrophobic silica nanospheres allows for the formation of stable water-in-oil emulsions with a larger internal interface. This synergistic effect enables the particles to protect the droplets from coalescence and accelerate the emulsions sedimentation speed, while still maintaining the ability to redisperse the droplets by gentle shaking. The study provides a model to explain the phenomena observed in terms of droplet size measurements and cryo-SEM studies.

Summary: A membrane is a thin layer used for separation and purification processes, and nanomembranes made from nanofibers have the advantage of small size and improved efficiency. Electrospinning is a viable method for preparing nanomembranes. This review explores techniques to modify electrospun nanomembranes for process improvement and their potential applications, highlighting areas requiring further innovation.

Summary: Membrane separation is an effective method for addressing the global water crisis. The introduction of liquid-liquid interfaces in membrane systems can enhance wetting and reduce transport resistance, improving water flow without sacrificing rejection performance. This study provides insights for designing advanced membrane systems for water purification and energy conversion processes.

Summary: This study investigated the influence of nanotextured surface geometry on the interfacial thermal resistance (ITR) between hydrophilic solid walls and water/ice using molecular dynamics simulations. The results showed that narrower nanostructure gaps led to decreased ITR. Particularly, when H2O molecules were in the crystal form, the local ITR significantly increased.

Summary: A comprehensive understanding of surface reconstruction is crucial for developing high-performance lattice oxygen oxidation mechanism (LOM)-based perovskite electrocatalysts. Previous studies mainly focused on optimizing composition to reduce oxygen vacancy formation energy, thereby facilitating the surface reconstruction process. This study found that adding oxyanions (SO42-, CO32-, NO3-) into the electrolyte can effectively regulate the solid-liquid interface, significantly accelerating the surface reconstruction process and enhancing oxygen evolution reaction (OER) activities. Further studies showed that the added oxyanions can disrupt the dynamic equilibrium between adsorbed and generated OH- ions during surface reconstruction, leading to an acceleration of the process. Therefore, this finding is expected to contribute to a new understanding of the surface reconstruction process in LOM-based perovskite electrocatalysts.

Summary: In this study, grazing-incidence small-angle neutron scattering (GISANS) was used to investigate the depth-dependent orientation of self-assembled morphologies of block copolymers. The orientation of the microphase-separated structure differed at the polymer-air and polymer-substrate interfaces, as revealed by GISANS. The conversion of a hydrophobic-hydrophobic block copolymer to a hydrophilic-hydrophobic block copolymer significantly increased the segmental interaction parameter and caused microphase separation of the copolymers.

Summary: The impingement behaviors and splashing phenomena of droplets on solid substrates are investigated in this study. The prediction of droplet splashing is based on the pressure balance and energy balance equations. The driving forces for droplet spreading are hydrodynamic and hydrostatic pressures, while the opposing forces are capillary pressure and viscous stress. The occurrence of splashing depends on whether the driving forces overcome the opposing forces, and is affected by surface factors such as wettability and roughness.

Summary: The structural transformation of MnO2 during electrochemical reactions is investigated. Layered-MnO2 transforms into spinel-Mn3O4 with K+ ion intercalation in the first discharge process. From the second charge, spinel-Mn3O4 is gradually adjusted to a more stable lambda-MnO2 with a three-dimensional tunnel structure, enabling reversible intercalation/deintercalation of K+ ions in subsequent cycles. The MnO2@rGO electrode exhibits high specific capacitance and excellent cycling stability.

Summary: Electrocatalysis plays a crucial role in enhancing energy efficiency, reducing carbon emissions, and meeting global energy demands in a sustainable manner. Understanding the electrochemical reaction mechanisms at the electrolyte/electrode interfaces is essential for the development of advanced renewable energy technologies. However, direct probing of real-time interfacial changes under operating conditions is challenging and requires in situ methods. In this study, a new lab-based instrument utilizing ambient pressure X-ray photoelectron spectroscopy (APXPS) was introduced for in situ chemical analysis at liquid/solid interfaces. The instrument allows the investigation of surface intermediates, chemical environments, and electronic structures during electrochemical reactions.
