Highly ordered and tunable polyHIPEs by using microfluidics

Journal of Materials Chemistry B, 2014
We demonstrate how to generate highly ordered porous matrices from dextran-methacrylate (DEX-MA) using microfluidics. We use a flow focusing device to inject an aqueous solution of DEX-MA and surfactant to break the flow of an organic solvent (cyclohexane) into monodisperse droplets at a high volume fraction (above 74% v/v) to form an ordered high ...

Interconnected Porous Material Prepared Via High Internal Phase Emulsion Stabilized by Mixture of Fe3O4 and Tween85

MATEC Web of Conferences, 2016
PolyHIPE monoliths with open-cell structure were prepared using an oil-in-water Pickering high internal phase emulsion (HIPEs) template. Fe3O4 nanoparticles and Tween 85 were used to stabilize the HIPE.

Beyond Potency: Emerging Determinants and Optimization Strategies Enhancing Therapeutic Efficacy of Adult Stem Cells

Advanced Science, Volume 13, Issue 40, 17 July 2026.
Adult stem cell therapy requires more than high in vitro potency. This review proposes a systems framework in which cell‐intrinsic programs, instructive microenvironmental cues, and pre‐/post‐delivery engineering are co‐designed under standardized translational rules.

Nitrogen Chemistry and Pore Hierarchy Direct ORR Pathways in Polyazine–Derived Carbon Foams

ChemCatChem, Volume 18, Issue 14, 29 July 2026.
Independent control of nitrogen speciation and hierarchical porosity in polyHIPE‐derived carbon foams enables mechanistic insight into metal‐free oxygen reduction. Pyrrolic and hydrogenated‐pyridinic nitrogen within hierarchical pore networks favor the 2e− pathway to H2O2, while pyridinic nitrogen and increased microporosity direct the reaction toward ...

Effect of polyHIPE porosity on its hydrodynamic properties

Polymer Testing, 2021
Several polymerized high internal phase emulsions (polyHIPE) of various porosity but the same pore diameter were prepared. It was demonstrated that the pore size distribution of void pores and interconnecting pores is similar and it can be described by a log-normal distribution.

Preparation of Porous MOF‐Polymer Composites via High Internal Phase Pickering Emulsions for Dye Adsorption Applications

Chemistry – A European Journal, Volume 32, Issue 20, 27 May 2026.
A versatile method was developed to fabricate hierarchically porous monoliths using UiO‐66/TOCNC composites as Pickering emulsion stabilizers. The resulting polyHIPEs, produced under mild and scalable conditions, showed confirmed structural integrity through TGA, XRD, SEM, BET, and FT‐IR.

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...
