Summary: The swelling of charged polymeric networks in electrolytic solutions was studied using a classical thermodynamic model. The well-established theory of Donnan exclusion was examined, which predicts that with increasing electrolyte concentration, the exclusion of electrolytes from the gel would decrease. However, the model predicts that the magnitude of Donnan exclusion actually increases with increasing electrolyte concentration in a broad range of parameter space.

Summary: A series of soft PDMS rubbers was obtained by diluting reaction mixtures of a PDMS macromer and a crosslinker with an organic solvent. The softest rubber could swell up to 600 wt% when immersed in pure hexane at room temperature. The loosely crosslinked PDMS rubber had a significantly higher sorption amount and a lower sorption heat compared to conventional PDMS rubber, making it an indispensable sorbent for the recovery of flammable gases in the chemical and oil and gas industries.

Summary: This work proposes a simple experimental method based on 3D-printing technologies to characterize the stress of stimuli-responsive hydrogels under spatial geometric constraints. The results reveal the swelling behavior and stress variation of hydrogels under different confinement conditions. These findings can optimize the performance of swelling-based systems and understand the stress generated under other stimuli.

Summary: The long-known anomalous viscosity of colloidal dispersions of silica has been studied and several mechanisms have been proposed, including those related to the electrical double layer, hydration layer, and porous/gel layer at the silica-water interface. However, the actually operative mechanism remains unclear. By measuring the viscosity dependence on the concentration of indifferent electrolyte in highly diluted colloidal silica systems and interpreting it using the Einstein equation, the concept of a swellable polyelectrolyte gel layer is supported.

Summary: Thermo-responsive hydrogels of the LCST type swell below T-c and collapse above T-c, with modulation of T-c conventionally achieved by copolymerization with monomers of varying hydrophilicity. Introduction of polyelectrolyte monomers results in properties dependent on pH and ionic strength.

Summary: In this study, a novel approach was used to develop highly porous, fast swelling hydrogels with high mechanical performance by slightly modifying the traditional double network concept through emulsion template polymerization. The fabricated hydrogel had 40-70 micrometer size pores and ultimate compressive strength of 5-7 MPa. It demonstrated approximately 400 wt% water absorptivity in 15 seconds at 30 degrees C, which was attributed to the surface roughness of interconnected capillary channels.

Summary: Effective chromosome synapsis and crossover formation in wheat during meiosis is temperature-dependent. Mutations in genes such as TaDMC1-D1 lead to asynapsis and crossover failure at low and, to some extent, high temperatures. The findings have important implications for wheat breeding, especially in the face of climate change.

Summary: In this study, a poly(ionic liquid) catalyst with unique adsorption-swelling ability towards epoxides was synthesized through free radical polymerization. The catalyst showed superior CO2 cycloaddition performance under atmospheric pressure and cocatalyst-/metal-/solvent-free conditions. The adsorption-swelling property of the catalyst was controllable, reversible, and widespread, allowing for efficient and selective reaction. The catalyst also exhibited good reusability and stability after multiple cycles. This work provides new insights for improving CO2 cycloaddition activity and guides the design of efficient poly(ionic liquid) catalysts for atmospheric CO2 conversion.

Summary: Two hexanuclear paddlewheel-like clusters with six carboxylic-acid pendants have been isolated in the presence of polar solvent guests. The clusters form alternately stacked lamellar architectures with H-bonded solvent layers. Under UV illumination, the silver cluster displays greenish-yellow photoluminescence while the copper cluster shows photoluminescence in the near-IR region in the solid state.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.

In this study, we investigate the effects of microfluidic flows and acoustic fields on the molecular orientation and optical response of nematic liquid crystals. We identify several previously unknown structures and explain them through calculations and simulations. These findings hold promise for the development of new systems combining sound, flow, and confinement.
