“…Subsequently, through the self-assembly actions of the CTAB and TEOS, a core-shell mesoporous material with a two-mode structure is obtained. Wiesner et al [70] have reported the synthesis of aminated-mesoporous particles with adjusted particle sizes. Contrary to findings in the previous work, the presence of ethyl acetate in an ammonia solution increased the amount of aminosilane connected to the mesoporous material greatly, while its ordered shape remained intact.…”

“…Recently, gemini surfactants (GSs) have been investigated as versatile templates for the synthesis of silica mesopores. GSs have hydrophobic heads and interconnected spacers between or near the hydrophobic chains, allowing convenient aggregations in solution [70]. Li et al used GS with 14-2-14 molecules to prepare hollow mesoporous silica (HMS) [71].…”

The application of silica mesoporous structures in drug delivery and the removal of pollutants and organic compounds through catalytic reactions is increasing due to their unique characteristics, including high loading capacities, tunable pores, large surface areas, sustainability, and so on. This review focuses on very well-studied class of different construction mesoporous silica nano(particles), such as MCM-41, SBA-15, and SBA-16. We discuss the essential parameters involved in the synthesis of these materials with providing a diverse set of examples. In addition, the recent advances in silica mesoporous structures for drug delivery and catalytic applications are presented to fill the existing gap in the literature with providing some promising examples on this topic for the scientists in both industry and academia active in the field. Regarding the catalytic applications, mesoporous silica particles have shown some promises to remove the organic pollutants and to synthesize final products with high yields due to the ease with which their surfaces can be modified with various ligands to create appropriate interactions with target molecules. In the drug delivery process, as nanocarriers, they have also shown very good performance thanks to the easy surface functionalization but also adjustability of their porosities to providing in-vivo and in-vitro cargo delivery at the target site with appropriate rate.

“…It is a viscous, yellow, oily liquid [140,141]. It can be prepared using: (i) oxalyl chloride according to Scheme 1 prior to evaporation of unnecessary substances [142], (ii) phosphorus trichloride in chloroform (yield 92.5%) [140] or (iii) thionyl chloride in presence of 4-dimethylaminopyridine [143]. It can be used as a substrate for the synthesis of macroinitiators for atom transfer radical polymerization (ATRP) reactions [142], rosin phosphate esters [140], N -hydroxyethylacrylamide ester of dehydroabietic acid [144], dehydroabietic ethyl methacrylate [145,146], dehydroabietic propargyl ester [147] dehydroabietic hexyl acrylate [148], as well as other intermediates in synthesis of various surfactants [143,149] and medicines [141,150,151].…”

A comprehensive review of the publications about rosin-based chemicals has been compiled. Rosin, or colophony, is a natural, abundant, cheap and non-toxic raw material which can be easily modified to obtain numerous useful products, which makes it an excellent subject of innovative research, attracting growing interest in recent years. The last extensive review in this research area was published in 2008, so the current article contains the most promising, repeatable achievements in synthesis of rosin-derived chemicals, published in scientific literature from 2008 to 2018. The first part of the review includes low/medium molecule weight compounds: Especially intermediates, resins, monomers, curing agents, surfactants, medications and biocides. The second part is about macromolecules: mainly elastomers, polymers for biomedical applications, coatings, adhesives, surfactants, sorbents, organosilicons and polysaccharides. In conclusion, a critical evaluation of the publications in terms of data completeness has been carried out with an indication of the most promising directions of rosin-based chemicals development.

BACKGROUND It is well known that plant essential oils have good antimicrobial activity. However, their strong volatility and intense odor limit their application. Mesoporous silica (MCM‐41), a non‐toxic mesoporous material with excellent loading capability, is a promising delivery system for different types of food ingredients in the food industry. RESULTS In this study, we first performed component analysis of pepper fragrant essential oil (PFEO) by gas chromatography – mass spectrometry (GC–MS), then the MCM‐41 host was prepared, and the essential oil functionalized nanoparticles (EONs) were formed by embedding PFEO into mesoporous silica particles. Further analysis indicated that the particle size and zeta potential of EONs were 717 ± 13.38 nm and − 43.90 ± 0.67 mV, respectively. Transmission electron microscopy (TEM) images showed that EONs had an inerratic morphology and stable structure. The bactericidal activities of PFEO and EONs against Escherichia coli (E. coli), Salmonella enterica (S. enterica), Staphylococcus aureus (S. aureus) and Listeria monocytogenes (L. monocytogenes) were subsequently tested using the twofold dilution method. Results indicated that, after 48 h incubation, minimum bactericidal concentrations (MBC) of EONs used against gram‐negative bacteria were decreased to a greater degree than those of PFEO, suggesting that nanoencapsulation by MCM‐41 can improve antimicrobial activity. Atomic force microscopy (AFM) observation also confirmed that EONs showed a notable inhibitory effect against E. coli by disrupting cell membrane structure. CONCLUSION Pepper fragrant essential oil nanoencapsulation could be a very promising organic delivery system in food industry for antimicrobial activity enhancement. © 2019 Society of Chemical Industry
