Proto-calcite and proto-vaterite in amorphous calcium carbonates.

Crystallization of calcium carbonate, typically, progresses sequentially via metastabIc phases. Amorphous CaC03 (ACC) generally forms initially, both in vitro and in vivo, and is the precursor of the predominant anhydrous polymorphs (calcite, aragonite, and vaterite). [I-I3] A new picture of the crystallization of calcium carbonate is emerging, which involves transformations of clusters to ACC ...

Room temperature vortex fluidic synthesis of monodispersed amorphous proto-vaterite.

Monodispersed particles of amorphous calcium carbonate (ACC) 90 to 200 nm in diameter are accessible at room temperature in ethylene glycol and water using a vortex fluidic device (VFD). The ACC material is stable for at least two weeks under ambient conditions.

Proto-Rigidity

It is often claimed that Kripke (1980) and Putnam (1975) established that many predicates, most importantly natural kind predicates, are like proper names in being rigid designators. This insight is generally regarded as having important consequences in the theory of necessary truths: the rigidity of terms such as 'Hesperus', 'Phosphorus', 'water' and 'H 2 O' is used in explaining why identity ...

Linguistics and archaeology have been, and continue to be, entwined in the discourse on the early human history of the Pacific. It is commonly assumed, explicitly or otherwise, that the bearers of the Lapita culture were speakers of Proto-Oceanic, the ancestor of the Austronesian languages of most of the Pacific. In this discursive piece, the chronological data for the location and timing of th...
