Expanded vermiculite (eVMT) has been studied as a risk-free, general-purpose absorbent for liquid hazards due to its excellent thermal and chemical stability. Here, was expanded by two steps: exfoliation 30 wt% H2O2 treatment at 60 °C subsequent expansion microwave heating. This two-step produced more homogenously separated concertina-like eVMTs with higher total pore volume of 7.75 cm3 g−1 tha...

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 ...

The saturable absorber of niobium diselenide (NbSe2), with a wide working bandwidth and excellent nonlinear optical response, was prepared using liquid-phase exfoliation. Its saturation intensity modulation depth were 5.35 MW/cm2 6.3%, respectively. Stable mode-locking center wavelength 1558.7 nm an erbium-doped fiber laser based on NbSe2 successfully achieved. maximum average output power the ...

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...

Exfoliation of two-dimensional phosphorene from bulk black phosphorous through chemical means is demonstrated where the solvent system of choice (choline chloride urea diluted with ethanol) has the ability to successfully exfoliate large-area multi-layer phosphorene sheets and further protect the flakes from ambient degradation. The intercalant solvent molecules, aided by low-powered sonication...
