The non-isothermal crystallization behaviour of high purity b-phase and a-phase polypropylene (PP) and their calcium carbonate-Γlled composites was investigated by means of di β erential scanning calorimetry. High purity b-PP polymer was prepared by adding an e β ective b-nucleator consisting of equal
## Abstract Control over crystal morphology of calcium carbonate (CaCO~3~) was investigated by simply changing the stirring speeds in the process of CaCO~3~ formation. Scanning electron microscopy (SEM) and powder Xβray diffraction (XRD) measurements explore the morphology evolution of CaCO~3~ at v
The crystallization of calcium carbonate was carried out by mixing CaCl 2 and Na 2 CO 3 solutions. The morphology of precursor formed prior to the nucleation of the polymorphous crystals (calcite and vaterite) varies depending on the feed concentration. The faster nucleation rate of polymorphous cry
## Abstract Multistep hydrogen isotope exchange reactions, such as the Γonization of a carbon acid via a carbanion intermediate in a protic solvent, when conducted using an isotopic tracer to monitor the exchange, have the unusual feature that their rateβdetermining steps always refer to the transf
