Technically important wide band-gap semiconductors such as GaN, AlN, ZnO and SiC are crystallized in polar structures. Taking SiC as an example, we investigate the effect of surface polarity on the wetting behavior by water using experiments and molecular dynamic simulations. It is found that the contact angle (CA) of deionized water on the carbon-face (C-face) is significantly larger than that on the silicon-face (Si-face) for both 6H-SiC and 4H-SiC, while the CA of tetrachloromethane is almost the same on these two faces...

Ultrathin black phosphorus (BP) is one of the promising two-dimensional (2D) materials for future optoelectronic devices. Its chemical instability in ambient conditions and lack of a bottom-up approach for its synthesis necessitate efficient etching methods that generate BP films of designed thickness with stable and high-quality surfaces. Herein, reporting a photochemical etching method, we demonstrate a controlled layer-by-layer thinning of thick BP films down to a few layers or a single layer and confirm their Raman and photoluminescence characteristics...

BACKGROUND: Air-drying of etched and rinsed dentin surface may force the exposed collagen fibrils to collapse. Blot-drying is an alternative method to wipe the excess water from the dentin surface without compromising the monomer penetration. Contemporary total etch adhesives contain ethanol/water or acetone as solvent in which resin monomers are dissolved. Solvent type of the adhesive system has an important role in bonding to dentin. An adhesive containing tertiary butanol as an alternative solvent has been in the market...
