Halloysites are cheap, abundantly available, and natural with high mechanical strength and biocompatibility. In this paper, a novel halloysite nanotube [HNT]-based gene delivery system was explored for loading and intracellular delivery of antisense oligodeoxynucleotides [ASODNs], in which functionalized HNTs [f-HNTs] were used as carriers and ASODNs as a therapeutic gene for targeting survivin...

Strain-rate-dependent mechanical properties and impact performance of manufactured epoxy-based nanocomposites are investigated. As reinforcements, fumed silica (FS) halloysite nanotube (HNT) used alongside Albipox 1000 Nanopox F700. First, the internal structures composites visualised using scanning electron microscopy (SEM). To identify strain-rate-dependent properties, three-point bend tests ...

A field-mapping and crystal-chemical study of two aluniteand halloysite-rich deposits in the Turplu area, situated northwest of Balıkesir on the Biga Peninsula of northwest Turkey reveals a mineralogically diverse and a potentially economic clay deposit. The mineral assemblage along fault zones is dominated by halloysite and sometimes alunite. The alunite is nearly end-member in composition (a ...

Contamination of soil by copper (Cu) has become a serious problem throughout the world, causing the reduction of agricultural yield and harmful effects on human health by entering the food chain. A glasshouse pot experiment was designed to evaluate the potential use of halloysite as an immobilizing agent in the aided phytostabilization of Cu-contaminated soil, using Festuca rubra L. The content...

Selective fatty acid hydrophobization of the inner surface of tubule halloysite clay is demonstrated. Aqueous phosphonic acid was found to bind to alumina sites at the tube lumen and did not bind the tube's outer siloxane surface. The bonding was characterized with solid-state nuclear magnetic resonance ((29)Si, (13)C, (31)P NMR), Fourier transform infrared (FTIR), and X-ray photoelectron spect...

Molecular dynamics simulation was applied to study the irreversible strain through loading and unloading cyclic tests of polyurethane (PU) reinforced with halloysite nanotube (HNT). The influences stretching cycle rate, different temperatures, volume density rate hard soft domain PU were studied on permanent set. results illustrate that residual increasing when is increasing, for example, load ...

This study investigates the role of halloysite nanotube as a mineral-based thixotropic admixture to 3D printable geopolymer mortar. The first part this paper focuses on fundamental characterization thermal evolution at 30–1000 °C. In second part, we show how calcination and concentration influence fresh hardened properties 3D-printable It was found that regardless treatment, using only 1–2 wt% ...

Halloysite is naturally occurring nanotubular clay with a phyllosilicate structure and widely used as solid support to modify various redox mediators. We prepared hemin modified halloysite (Hemin/HNT) by simple impregnation method, in which known amount of was dispersed ethanolic solution 1% reacted for 12 h. The resulting pure Hemin/HNT employed electrocatalyst the electrochemical oxidation ni...
