The experiment was carried out in order to evaluate the effects of trace element immobilizing soil amendments, i.e., chalcedonite, dolomite, halloysite, and diatomite on the chemical characteristics of soil contaminated with Cr and the uptake of metals by plants. The study utilized analysis of variance (ANOVA), principal component analysis (PCA) and Factor Analysis (FA). The content of trace el...
در این پایان نامه خواص و جنبه های مختلف کربن معرفی و مروری کلی بر روشهای ساخت ، ساختار و خواص انواع مختلف کربن از کربنهای bulk(شامل گرافیت ، گرافیت turbostratic، الیاف کربن، دوده هاو ... ) تا کربنهای نانومقیاس (شامل fullerenes ، کپسولهای نانومقیاس ، کربنهای nanotube و ... ) ارائه می شود. عمده کار متوجه کربنهای nanotube(اعم از multi-wall و single-wall ) است و ساختار ، عیوب شبکه ای و روشهای ساخت ...
Halloysite is an aluminosilicate clay that has been widely used for controlled drug delivery, immobilization of enzymes, and for the capture of circulating tumor cells (CTCs). Surface modification of halloysite by organosilanes has been explored to improve their properties. In this study halloysite clay nanotubes (HNTs) were functionalized by two different organosilanes: Trimethoxy(propyl)silan...
The adsorption/desorption characteristics for light and heavy rare earth elements (REEs) on halloysite illite (which are beneficial the utilization of ion-adsorption RE ore) were systematically investigated compared. Additionally, fully charactered by XRD, SEM, microscope, zeta potential, nitrogen adsorption–desorption isotherms buffer pH to build relationship between mechanisms minerals’ prope...
A new generation photocatalyst CuFe2O4/rGO/halloysite nanotube (HNT) was manufactured using a simple procedure in this work. Material characterisation results reveal that the CuFe2O4 active phase with size of around 30-40 nm is spread rather consistently across sandwich-like structure rGO/HNT. The material's bandgap energy 1.9 eV, which boosts capacity to function even visible light area. catal...
