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...

Abstract Exploring two dimensional (2D) materials is important for further developing the field of quantum materials. However, progress in 2D material development limited by difficulties with their production. Specifically, freestanding bulk non-layered structures remain particularly challenging to prepare. Traditionally, chemical or mechanical exfoliation employed obtaining materials, but thes...

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...

Since the first reported isolation of graphene by peeling graphite with cellophane tape in 2004, there has been a paradigm shift in research. In just nine years, graphene has had a major impact on fields ranging from physics and chemistry to materials science and engineering leading to a host of interdisciplinary advances in nanotechnology. Graphene is attractive because it possesses many extra...

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.

Abstract The development of high-precision large-area optical coatings and devices comprising low-dimensional materials hinges on scalable solution-based manufacturability with control over exfoliation procedure-dependent effects. As such, it is critical to understand the influence technique-induced transition metal dichalcogenide (TMDC) properties that impact design, performance, integration a...

A novel technique to lithograph the MoS2 surface is described here. Mechanically exfoliated MoS2 flakes have been patterned with an atomic force microscope tip. After the patterning process, the lithographed areas have been removed by selective chemical etching. The electronic properties of the MoS2 flakes have been analyzed with spatially resolved photoelectron spectroscopy, with tunable incid...
