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 ...

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...

Porous maleic anhydride–styrene–divinylbenzene copolymer beads

Journal of Applied Polymer Science, 1987
The formation of the porosity and the pore stability in maleic anhydride–styrene–divinylbenzene (MAn–St–DVB) copolymer beads were investigated using the apparent density measurements of the samples dried from methanol (maximum porosity) and from dioxane (stable porosity).

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

Journal 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.
