Structural characterisation of alkyl amine-capped zinc sulphide nanoparticles

Abstract

Graphical abstractHighlights► Combined X-ray and light scattering study was performed on ZnS nanoparticles. ► Ligands with different steric properties, dodecyl- and oleylamine, are compared. ► Nanoparticles exhibit sizes of 3–5 nm. ► Thickness of the ligand shell is about 1.9 nm.

Hyaluronate Targeted Solid Lipid Nanoparticles of Etoposide: Optimization and In Vitro Characterization

“…Therefore, as SA is structurally more similar to the lipid phase of cetyl alcohol compared to DDA, it is more miscible in the lipid phase. Similar results have been obtained in studies by Kremser et al [20] and Sun [21]. Increase in cetyl alcohol/amine ratio in DDA containing SLNs caused decrease in particle size (Figure 2), which could be because of the low miscibility of the DDA with cetyl alcohol, so that lower amounts of DDA had a lower negative effect of particle size leading to smaller particle size when its concentration is decreased in the SLNs (Figure 2).…”

“…Because of high expression of CD44 by cancer cells, targeting of drugs to CD44 by HA is an effective strategy to treat cancers. HA as bound to the nanoparticles, in addition to its targeting roll, can protect from nanoparticles against body phagocytosis system [19][20][21]. This ligand has been used in different nanoparticulate delivery systems for chemotherapeutic agents such as doxorubicin [22], epirubicin [23], paclitaxel [24], mitomycin C [25], siRNA [26], and DNA [27].…”

One-pot synthesis of reduced graphene oxide/zinc sulfide nanocomposite at room temperature for simultaneous determination of ascorbic acid, dopamine and uric acid

“…The diffraction peaks marked with solid-square could be correctly indexed as cubic phase ZnS, which are in good agreement with the standard values (JCPDS Card No. 05-0566) [59]. The diffraction peak marked with hollowsquare is the characteristic peak of rGO [58].…”

Enriched Doping Level and Tuned Fiber Fractal Dimensions in Nonwoven Carbon‐Doped Polyaniline for Efficient Solid‐State Supercapacitors

“…Further investigation of samples was performed by using the pair‐distance distribution function (PDDF) or the p ( r ) function, which is the direct Fourier transform of the scattering curve I ( q ) . This allows the calculation of the full range of q (wave vector) into real space, which is easier to interpret than the scattering plot . All the PDDF curves show a pronounced peak in the low‐ r region and an extended long tail in the high‐ r region (Figure d ), which is a significant feature of fiber‐like structures .…”
