Bulk layered transition metal dichalcogenides (TMDs) show diamagnetic properties. When exfoliated, the materials' band gap increases and changes from an indirect band gap to a direct one. During the exfoliation, the TMDs may undergo a phase transition from 2H to 1T polymorph, which is likely electronically driven and accompanied by a metal-insulator transition. A significantly higher efficiency...

Background: Papillon-Lefevre syndrome is a rare autosomal recessive genetic disorder which is characterized by palmar plantar hyperkeratosis with precocious progressive periodontal disease that results in premature exfoliation of primary and permanent dentitions. Consanguinity of parents is evident in about one third of cases. Context: Here we report a case of 22 year old male who presented wit...

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...

The Chediak-Higashi syndrome (CHS) is a rare hereditary fatal disease, if not treated. These changes are associated with various diseases and syndromes that mainly cause periodontal disease and thus the premature loss of teeth. This paper describes the monitoring of premature loss of primary teeth that began when the child was 5 years old. On presentation his teeth were mobile and there was a h...

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 ...
