Dislocation slip and twinning stress in shape memory alloys- theory and experiments
… stress in dislocation slip and critical twin nucleation stress in twinning is essential to facilitate the design of new transforming alloys. This thesis presents an advanced energetic approach to investigate the attributes of phase transformation, slip and twinning in SMAs utilizing Density …

The development of h Homogeneous nucleation rate model for thermoplastic foams based on a molecular partition function and Fickian diffusion
An improved homogeneous nucleation rate model for thermoplastic foams has been developed. This model does not rely on experimentally determined parameters and only uses pure component physical property data and a binary diffusion coefficient. This model, like those derived from classical nucleation …

Actin polymerization dynamics at the leading edge
… the lifetime of an organism. While the dendritic nucleation model explains the initiation and organization of the actin network in lamellipodia, two questions need to be answered. In this study, I reconstructed cellular motility in vitro to investigate how actin filaments are organized to …

The Molecular Interaction Between Type Ii Diabetes and Alzheimer’S Disease Through Cross-Seeding of Protein Misfolding
… accumulation of these proteins follows a seeding-nucleation model where misfolded soluble oligomers act as nuclei to propagate misfolding by recruiting other native proteins. Cross-seeding occurs when oligomers composed by one protein seed the aggregation of a different protein. Our hypothesis is …

Nucleation of the isothermal martensitic transformation in iron-nickel-manganese alloys
… detectable amount of martensite) and the initial nucleation rate have been determined as a function of subzero reaction temperature and austenitic grain size in three iron-nickel manganese alloys containing 23-25 percent nickel, 2-3 percent manganese and 0.02-0.04 percent carbon. The isothermal …

Silicium aus der Gasphase : Optimierung der Gasphasenabscheidung von Silicium aus Silan
… different diluent gases has been analyzed with model calculations. Results of this model regarding the time scale of the gas phase reactions and the influence of silane in different buffer gases have been used in the definition of suitable deposition conditions for the experiments. In the model, …
