“…Further, polymer segments capable of engaging in strong interactions with the external ZIF surface dramatically enhance hydrolytic stability at low ZIF concentrations. Beyond providing new opportunities for designing aqueous porous liquids, our mechanistic insights into the infiltration behavior of polymers should be relevant to the use of polymer-functionalized metal–organic frameworks for mixed-matrix membranes, ,, polymerization templates, , and drug delivery. , …”

Aqueous dispersions of microporous nanocrystals with dry, gas-accessible pores�referred to as "microporous water"�enable high densities of gas molecules to be transported through water. For many applications of microporous water, generalizable strategies are required to functionalize the external surface of microporous particles to control their dispersibility, stability, and interactions with other solution-phase components� including catalysts, proteins, and cells�while retaining as much of their internal pore volume as possible. Here, we establish design principles for the noncovalent surface functionalization of hydrophobic metal−organic frameworks with amphiphilic polymers that render the particles dispersible in water and enhance their hydrolytic stability. Specifically, we show that block co-polymers with persistence lengths that exceed the micropore aperture size of zeolitic imidazolate frameworks (ZIFs) can dramatically enhance ZIF particle dispersibility and stability while preserving porosity and >80% of the theoretical O 2 carrying capacity. Moreover, enhancements in hydrolytic stability are greatest when the polymer can form strong bonds to exposed metal sites on the external particle surface. More broadly, our insights provide guidelines for controlling the interface between polymers and metal−organic framework particles in aqueous environments to augment the properties of microporous water.

“…This can lead to their encapsulation within the MOF structure during mechanochemical synthesis. 98 On the other hand, continuous flow mechanochemical synthesis combines milling with fluid flow in flow reactors, enabling the continuous production of MOFs with enhanced crystallinity, purity, and yield. 99 In this method, solid reactants are continuously fed into a milling chamber, where mechanical forces generated by milling promote the formation of MOF crystals.…”

“…This mixture of fatty acid methyl esters boasts several environmental advantages, notably reducing emissions of CO, unburned hydrocarbons, particulates, and SO 2 . While both homogeneous and heterogeneous catalysts have been proposed, homogeneous catalysis is the preferred method for achieving a high yield of methyl/ethyl esters (Kiss et al, 2010;FIGURE 5 Basic concept for ball impact energy in mechanochemical synthesis (Wang et al, 2023).…”

Mechanochemistry and oleochemistry and their combination have been known for centuries. Nevertheless, bioeconomy and circular economy concepts is much more recent and has motivated a regain of interest of dedicated research to improve alternative technologies for the valorization of biomass feedstocks. Accordingly, this review paper aims essentially at outlining recent breakthroughs obtained in the field of mechanochemistry and oleochemicals such as triglycerides, fatty acids, and glycerol derivatives. The review discusses advances obtained in the production of small chemicals derived from oils with a brief overview of vegetable oils, mechanochemistry and the use of mechanochemistry for the synthesis of biodiesel, lipidyl-cyclodextrine, dimeric and labelled fatty acids, calcium diglyceroxide, acylglycerols, benzoxazine and solketal. The paper also briefly overviews advances and limits for an industrial application.

Metal–organic framework composites from a mechanochemical process

Abstract: Metal-organic frameworks (MOFs) consist of metal ions or clusters coordinated with organic ligands such as imidazolate or carboxylate ligands. Owing to MOFs’ high porosity and surface area, researchers have applied...
