Guanidinium-based covalent organic framework membrane for single-acid recovery (open access)

Guanidinium-based covalent organic framework membrane for single-acid recovery

Article discusses how, although acids are extensively used in contemporary industries, time-consuming and environmentally unfriendly processes hinder single-acid recovery from wastes containing various iconic species. The authors rationally designed a membrane with uniform angstrom-sized pore channels and built-in charge-assisted hydrogen bond donors that preferentially conducted HCl while exhibiting negligible conductance for other compounds.

Spatially confined protein assembly in hierarchical mesoporous metal-organic framework (open access)

Spatially confined protein assembly in hierarchical mesoporous metal-organic framework

Article discusses how the immobilization of biomolecules into porous materials could lead to significantly enhanced performance in terms of stability towards harsh reaction conditions and easier separation for their reuse. To gain insights into the spatial arrangement of biomolecules within the nanopores, the authors used in situ small-angle neutron scattering (SANS) to probe deuterated green fluorescent protein (d-GFP) entrapped in a mesoporous MOF.
