Perfluorinated sulfonic acids have been immobilised into mesoporous silica frameworks by a one-step process, representing the first example of the successful incorporation of charged silanes using this route, and have been shown to be excellent catalysts for Brønsted acid catalysed transformations.

A novel electrochemical aptasensor based on bimetallic zirconium and copper oxides embedded within mesoporous carbon (denoted as ZrOCuO@mC) was constructed to detect miRNA. The porous ZrOCuO@mC was created through the pyrolysis of bimetallic zirconium/copper-based metal-organic framework (ZrCu-MOF). The substantial surface area and high porosity of ZrOCuO@mC nanocomposite along with its robust affinity toward aptamer strands, facilitated the effective anchoring of aptamer strands on the ZrOCuO@mC-modified electrode surface.

Preserving fertility is important in men under radiation therapy because healthy cells are also affected by radiation. Supplementation with antioxidants is a controversial issue in this process. Designing a biocompatible delivery system containing hydrophobic antioxidants to release control may solve these disagreements.

Enhancing the catalytic performance and durability of M-N─C catalyst is crucial for the efficient operation of proton exchange membrane fuel cells (PEMFCs) and Zn-Air batteries (ZABs). Herein, an approach is developed for the in situ fabrication of a MOFs-derived porous carbon material, co-loaded with Co nanoparticles (NPs) and Co-N sites and integrated onto Fe-doped carbon nanotubes (CNTs), named Co-NC/Fe-NCNTs. Incorporating polymer-wrapped CNTs improves MOFs dispersion annealing at high temperature, which amplifies the three-phase boundary (TPB) by generating much more mesopores and exposing additional active sites within the catalysts layer.

This study describes the preparation of novel hybrid aerogels derived from gelatin (Gel), incorporating Br-functionalized zirconium-based metal-organic framework (UiO-66-Br; MOF) as modifying agent to effectively eliminate phosphate and fluoride ions from aqueous environments. The adsorption performance of MOF decorated Gel (Gel-xMOF) hybrid aerogels was investigated under different conditions, including agitation time, adsorbent dosage, solution pH, initial phosphate and fluoride concentrations, coexisting ions, and temperature. The functional groups of the gelatin network, coupled with UiO-66-Br, enhanced the adsorption performance of phosphate and fluoride ions from aqueous solutions.
