The $19 treatment (it’s currently on sale at Amazon) reduces discoloration, hydrates and exfoliates brittle nail plates and loosens damaged layers to reveal pinker, smoother nails. It applies just like regular nail polish; cover each nail with a thin layer of the formula daily, as well as the underside of the nail’s free edge. WebLaves phases constitute the largest group of intermetallic phases. These very strong but brittle phases may not be usable as monolithic materi-als, but as strengthening phases, e.g. in iron aluminium alloys, Co-based alloys or steels. They exist with three different crystallographic structures, i.e. polymorphs, two hexagonal and a cubic.
