The Role of Intraparticle Diffusion in Kinetic Model Discrimination: Proof of Concept Testing for Methanol Dehydration

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 21, Issue 4, July/August 2026.
ABSTRACT The rate of a heterogeneous catalytic process may simultaneously be described by several rate equations. In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate‐limited regime to an ...

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

open access: yesChemCatChem, 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 ...

Recovery of gangliosides from aqueous solutions on styrene-divinylbenzene copolymer columns [PDF]

open access: yesJournal of Lipid Research, 2002
An investigation was made using a styrene-divinylbenzene copolymer as a solid phase sorbent to recover gangliosides from aqueous solutions. A comparison with octadecyl-bonded (C18) silica gel showed that the general procedure used to purify gangliosides on C18 silica gel could be used with the copolymer.

Macroporous styrene-divinylbenzene copolymers: Formation of stable porous structures during the copolymerization

open access: yes, 1998
The variation of the pore structure of styrene-divinylbenzene (S-DVB) copolymer beads depending on the polymerization time was investigated. Macroporous S-DVB copolymer beads with 10 mol % DVB content were prepared in the presence of cyclohexanol as a ...
