With the aim to capture and subsequent selective trapping of CO2, a nanocomposite has been developed through selective modification of the outer surface of the halloysite nanotubes (HNTs) with an organosilane to make the nanocomposite a novel solid-phase adsorbent to adsorb CO2 from the atmosphere at standard ambient temperature and pressure. The preferential adsorption of three major abundant ...

A magnetic adsorbent can be easily recovered from treated water by magnetic force, without requiring further downstream treatment. In this research, amine-functionalized silica magnetite has been synthesized using N-[3-(trimethoxysilyl)propyl]-ethylenediamine (TPED) as a surface modification agent. The synthesized magnetic amine adsorbents were used to adsorb copper ions in an aqueous solution ...

Cyclic azasilanes have been synthesized for the purpose of developing coupling agents appropriate for a variety of nanotechnologies including surface modification of nanoparticles, nanocrystals, mesoporous materials and substrates. N-Methyl-aza-2,2,4-trimethylsilacyclopentane is representative of this class of compounds. Preliminary data for the treatment of inorganic surfaces, including nanopa...

Various chemical modifications have been applied to study protein structures. In this paper, amidination of E. coli ribosomal proteins was investigated to profile the structure of this large protein/RNA complex. The extent of ribosomal protein amidination was correlated with the solvent accessibility of amine groups in E. coli ribosome crystal structures. The modification of many residues was c...

The Turkevich synthesis method of Au nanoparticles (AuNPs) was adopted for direct fabrication of SiO2@Au and TiO2@Au core-shell nanostructures. In this method, chloroauric acid was reduced with trisodium citrate in the presence of amine-functionalized silica or titania submicroparticles. Core-shells obtained in this way were compared to structures fabricated by mixing of Turkevich AuNPs with am...

In general, seed germination is improved by low-pressure plasma (LPP) treatment using precursors such as air, nitrogen, argon, or water (H2O). Here, H2O-based LPP the optimized parameters of 10 W and s improves Bambara groundnut seeds 22%. increases wettability roughness hilum while oxidizing surface with carboxyl amine groups. this seeds, combinatory etching chemical modification facilitated i...

Abstract In this work, the effect of common functional groups, namely hydroxyl, formyl, carboxyl, and amine groups on interfacial behavior surface-modified glass fiber-reinforced epoxy is investigated at molecular scale. The properties epoxy/silica coated with different group systems are quantified by performing pulling test using steered dynamics simulations. It found that system hydroxyl has ...
