Summary: This study reports the fabrication and characterization of porous PDMS structures using the solvent evaporation-induced phase separation technique. Different pore sizes were achieved by tuning the water to THF ratio, and a range of elastic moduli was obtained by adjusting the solvent and non-solvent content in the solution. The porosity of the structure was found to be mainly controlled by the PDMS concentration, with the water/THF ratio having a negligible effect.

Summary: This study investigates the effects of asphaltene, resin, and petroleum acid on the phase inversion, stability, and oil-water interface characteristics of emulsions. The synergy of asphaltene and resin is found to be the key to the emulsion phase inversion, with the optimal ratio being 1:3. The addition of petroleum acid accelerates the phase inversion process. Asphaltene and resin synergistically reduce the interfacial tension of oil and water, while excessive resin increases the interfacial tension by competing with asphaltene for adsorption. The addition of petroleum acid significantly decreases the interfacial tension. Asphaltene has a greater influence on the expansion modulus than resin, and the synergistic effect of asphaltene and resin increases the expansion modulus. However, the addition of petroleum acid decreases the expansion modulus due to its small molecular weight. The synergy of asphaltene and resin enhances the emulsion stability, with asphaltene playing a pivotal role in stabilizing the emulsion. On the other hand, the addition of petroleum acid severely destroys the emulsion stability.

Summary: The study indicates that the emulsifying performance of polymeric emulsifiers is influenced by counter ions, terminal groups, and chain lengths. Emulsifiers neutralized with KOH show better emulsifying performance than those neutralized with NaOH, and emulsifiers with a hydrophilic group at one end are more stable than those with hydrophilic groups at both ends. The chain length of polymeric emulsifiers also affects the stability of emulsions.

Summary: The effect of monomer droplet size on particle formation mechanism in aqueous heterogeneous polymerization was investigated. Different sizes of monomer droplets were used under various mixing methods. It was found that block copolymer micelles formed high order morphologies regardless of the extent of mixing, while monomer droplet nucleation led to the formation of only spherical nanoparticles. The findings suggest that the formation of spherical nanoparticles becomes predominant when the loci of polymerization change to monomer droplets.

Summary: RP-AESO porous materials prepared by emulsion template have uniform pore size distribution, hydrophobic properties, and oil absorption capacity. With increasing concentration of H-ESO-HEC, the pore density of RP-AESO porous materials increases and the average pore size decreases, leading to a decrease in compressive strength. Furthermore, these porous materials exhibit good reusability.

Summary: The study introduced a new type of stabilizers based on bishydrophilic, thermoresponsive microgels containing poly(N- isopropylacrylamide) (pNIPAM) chains with an affinity for both the PEO phase and dextran moieties, which can better control the stability of water-in-water emulsions. Experimental results showed that microgels with higher dextran content exhibited excellent stabilizing properties, with their structure and interaction changing with temperature to influence emulsion stability.

Summary: In this study, a novel dynamic covalent surfactant (TA-CBA) was synthesized, which can precisely manipulate the emulsion type by responding to acid/base stimuli. By adjusting the pH, the emulsion can undergo reversible phase inversion between water-in-oil (W/O) and oil-in-water (O/W) types, and the rheological parameters and stability of the emulsion can be restored to the original W/O type.

Summary: The versatile module design of precursor networks allows for flexible functionalization of nano-carbon electrode materials to meet adaptable energy storage demands. However, the transfer of functionality and network from precursor to carbon is still a work in progress. To enhance network strength and preserve precursor-level functionalities, a pre-stabilization route has been proposed. This approach successfully fixes more electroactive nitrogen into the resulting carbon microspheres compared to non-pretreated carbon, leading to increased ion-accessible platforms and superior energy storage performance.

Summary: This study reports a facile synthesis method for photoactivating fluorescent conjugated microporous polymer (CMP) microspheres using UV irradiation, resulting in unprecedented fluorescence enhancement as converse-photobleaching behavior. The fluorescence of CMP microspheres dispersed in various solvents is enhanced up to 60-fold by simple UV irradiation. The fluorescence enhancement is revealed to originate from the renovation of defects in the CMPs through solvent molecule adsorption, photo-dissociation, photo-interparticle coupling, and photochemical reactions, confirmed by control experiments, theoretical calculations, and molecular dynamics simulations.

Summary: By knitting ultrastable lock-and-key hydrogen-bonding networks between 2, 7-dinitropyrene-4, 5, 9, 10-tetraone (DNPT) and NH4+ charge carrier, the problem of easy dissolution of organic small molecules as high-capacity cathodes for Zn-organic batteries has been solved. The stable chemistry of NH4+ coordinated H-bonding overcomes the stability barrier and enables fast diffusion kinetics of non-metallic charge carrier.
