As one of the simple and efficient routes to access two-dimensional materials, liquid exfoliation has received considerable interest in recent years. Here, we reported on high-efficient liquid exfoliation of hexagonal boron nitride nanosheets (BNNSs) using monoethanolamine (MEA) aqueous solution. The resulting BNNSs were evaluated in terms of the yield and structure characterizations. The resul...

INTRODUCTION True exfoliation of lens capsule is a relatively rare disorder that has a thin, fluttering membrane in the anterior chamber, mainly located in the pupil area, which is believed to have split from the anterior lens capsule. CASE REPORT The authors present here a patient with true exfoliation and primary angle closure glaucoma in both eyes, the ultrastructure of one eye revealed th...

Supercritical fluid technology is a rapidly expanding analytical technique. Here we give a brief insight into the background of supercritical fluid technology and how supercritical fluid extraction and supercritical fluid chromatography work in analysis. The applications of these two techniques in forensic science are known to be important. The main area of forensic use of supercritical fluid t...

dissolution pressure and nozzle temperature effects on particle size and distribution were investigated for ress (rapid expansion of supercritical solution) process. supercritical co2 was used as solvent and ibuprofen was applied as the model component in all runs. the resulting ibuprofen nano-particles (about 50 nm in optimized runs) were analyzed by sem and laser diffraction particle size ana...

We demonstrated a facile and efficient approach for the fabrication of few-layer graphene in DMF and graphite nanosheets in water with the assistance of high pressure homogenization. This work provides a physical perspective for understanding the exfoliation of other layered materials in liquid phase exfoliation.

Exfoliation of a family of polyacetylenic porous layered covalent organic frameworks by means of a simple sonication procedure results in the obtention of nanolayer structures as observed by AFM and TEM measurements. Systematic AFM analysis of the isolated nanostructures reveals that the degree of exfoliation depends on the polymer architecture, thinner layers being observed when the pore size ...

We report a facile method for the production of graphene sheets through the liquid-phase exfoliation of graphite in organic solvents with addition of NaOH. NaOH was found to be intercalated into the interplanar spaces of graphite, and greatly improves exfoliation efficiency up to 20 times.

supercritical fluid extraction (scfe) is a soil remediation technology. at present, only a few companies are using from this method, all of which are technical based on conventional methods of extraction such as soilex solvent extraction. because of the hard enforcement of environmental conservation law, using green technology seems imperative. this paper endeavors to carry out the feasibility ...

Colonization and disruption of the epithelium is a major infection mechanism of mucosal pathogens. The epithelium counteracts infection by exfoliating damaged cells while maintaining the mucosal barrier function. The sexually transmitted bacterium Neisseria gonorrhoeae (GC) infects the female reproductive tract primarily from the endocervix, causing gonorrhea. However, the mechanism by which GC...
