Themed collection Mesostructured Materials

Peter Hesemann and Bao-Lian Su introduce the New Journal of Chemistry themed collection on the 12th International Mesostructured Materials Symposium (IMMS12).

This perspective explores strategies to modify the morphology, size, and surface chemistry of mesoporous silica nanoparticles to modulate intestinal barrier function, thereby improving the oral delivery of peptide drugs and biologics.

A greater interaction of water with the mesostructured TiO₂ surface than with meso or macro-mesoporous SiO₂ one is observed but, regardless of the matrix, the porosity shows no effect on water relaxation.

Reducing the size of the mesopores by adding a supramolecular biosourced hydrogelator gel after enzyme immobilization is an effective way to limit enzyme leaching during the catalytic reaction without damaging the mesostructure.

A surfactant-free synthesis route for VTMS-based aerogels, combined with strategies to minimize structural degradation during their production.

The morphology and porosity of iron oxide nanoparticles grown in deep eutectic solvents using mild conditions can be altered by addition of surfactant or water during syntheses.

Hollow mesoporous organosilica (HMO) nanoparticles with a controlled core cavity and a mesoporous organosilica shell are elaborated , the synthesis steps are checked by IR spectroscopy, the HMO are then tested for endocytosis and biocompatibility.

Fe₃O₄/ZnO heterostructures derived from Fe-doped ZIF-8 show enhanced visible-light-driven photocatalysis, enabling efficient tetracycline degradation and H₂O₂ production, offering dual-function solutions for water purification and green chemistry.

The interactions between new phosphorylated polysaccharide nanocrystals (cellulose, chitin) and aluminium oxo–hydroxo clusters e-Al₁₃O₄(OH)₂₄(H₂O)₁₂⁷⁺ are investigated and exploited to form mesoporous aluminophosphate materials.

The temperature stability window of mesoporous niobium tungstates is improved by 500 °C using pore backfilling strategies with carbon precursors.

Formulations based on encapsulation of neem oil or azadirachtin in mesoporous silica, which are easy to prepare, scalable and applicable at the foliar level by dispersion, have shown efficacy in the field against pests such as Eutetranychus banksi.

Optimisation of the synthesis procedure of MOF A520, an efficient water scavenger, and scaling up to prepare a 2.3 kg batch.

A BaO/Pt@mCeO₂-type nanocomposite catalyst was prepared for the selective synthesis of NH₃, which gave us an opportunity to understand the overall catalytic properties during an alternate gas-switching NO_x storage and reduction process.
