in our current study, supercritical water impregnation (scwi) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. the method allows nano-particles to place on support surfaces in extremely dispersed conditions. the silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

We report on the first exfoliation of MoS2 coaxial nanotubes. The single-layer flakes, as the result of exfoliation, represent the transition metal dichalcogenides' analogue of graphene. They show a very low degree of restacking in comparison with exfoliation of MoS2 plate-like crystals. MoS2 monolayers were investigated by means of electron and atomic force microscopies, showing their structur...

introduction: herpes zoster infection (hzi) is a viral disease with painful skin rashes and blisters in a limited area on one side of the body, often in a strip. osteonecrosis with spontaneous exfoliation of teeth in association with hzi of the mandibular nerve is a rare phenomenon. in this report, such an unusual complication of hzi is presented.   case report: the clinical course of a 53-year...

A simple chemical route for the exfoliation of kaolinite in the presence of polymerizable ionic liquids and the resulting obtainment of exfoliated nanocomposites is reported. The exfoliation was achieved using three different ionic liquids structurally bearing a vinyl group: 1-methyl-3-(4-vinylbenzyl)imidazolium chloride salt (IL_1), 1-methyl-1-(4-vinylbenzyl)pyrrolidinium chloride (IL_2), and ...

The main advantage for applications of graphene and related 2D materials is that they can be produced on large scales by liquid phase exfoliation. The exfoliation process shall be considered as a particular fragmentation process, where the 2D character of the exfoliated objects will influence significantly fragmentation dynamics as compared to standard materials. Here, we used automatized image...

Objective: To report the prevalence of pseudo exfoliation in association with Cataract and other ocular diseases at a tertiary eye care centre in Sindh, Pakistan. Methodology: This was a hospital based study at Liaquat University Eye hospital, Hyderabad Sindh, Pakistan conducted from July, 2005 to November, 2006. A total of 1450 subjects of more than fifty years with senile cataract were regist...

Chlorosulfonic acid assisted the exfoliation of MoS2 and WS2 resulting in retaining their semiconducting 2H-phase, sharply contrasting the semiconducting-to-metallic phase-transition observed with the currently available exfoliation techniques.
