Architectural design of core–shell nanotube systems based on aluminosilicate clay

Abstract

Nanoarchitectural approach to the design of functional nanomaterials based on natural aluminosilicate nanotubes and their multiple life-related applications are described. The main forcus is on the buildup of hybrid core-shell...

Prokaryotic and eukaryotic toxicity of halloysite decorated with photoactive nanoparticles

“…Halloysite is safe for medical applications, as it was demonstrated for 3 month oral consumption at 1 g daily. 55,56 It should be mentioned that the modifications of clay tubes influence their toxicity. The pristine nanotube and surfactant modified nanotubes were tested against three phytopathogenic bacteria Xanthomonas oryzae, Agrobacterium tumifeciens and Ralstonia solanacearum.…”

Curcumin loaded Ag–TiO2-halloysite nanotubes platform for combined chemo-photodynamic therapy treatment of cancer cells

“…This unique combination gives it a broad potential in terms of functionality, that is, it allows for different modication approaches by immobilizing two or more materials with different functional groups at the same time. 14,15 Lastly, it is biocompatible, readily available, and low cost. These excellent properties make HNTs a possible drug carrier.…”

A gram-scale fabrication of core–shell copper nanoparticles for efficient hydrogenation of nitroarenes

“…Hence, how to improve both the activity and selectivity of the catalysts using gaseous H 2 as the hydrogen source is still a big challenge for industrial production. [18][19][20] Keeping the above-mentioned in mind and extending our research on the hydrogenation of nitroarenes to arylamines, [21][22][23][24] in this study, a series of catalysts defined as Cu@NC/PC-t-x (t: pyrolysis temperature; x: pyrolysis times) have been designed and fabricated via a new chitosan auxiliary strategy (Scheme 1). It is worth mentioning that Cu NPs are well dispersed, which is attributed to the -NH 2 and -OH groups of chitosan can anchor and fix the Cu ions by a coordination bond during the calcination.…”
