Table 3.4 summarizes the different studies that have been performed to measure the growth and morphology of a hydrate film/shell at the water-hydrocarbon interface (where the hydrocarbon can be gas or liquid). 

Understanding the dependence of film structure and morphology on system layout and process parameters is a core topic for the further development of ZnO technology. Work is being performed on in situ characterization of deposition processes. Growth processes are simulated using Direct Simulation Monte-Carlo (DSMC) techniques to simulate the gas flow and sputter kinetics simulation and Particle-ln-Cell Monte-Carlo (PICMC) techniques for the plasma simulation [132]. 

Using glass substrates it has been observed that the resistivity increases appreciably with decreasing layer thickness at values below of 100-300 nm mainly due to a decrease of the electron mobility. A possible reason for such behavior is the different growth and morphology in the early stages of film growth. ...

The ideas described previously for understanding film morphology in terms of the local equilibrium and in terms of the surface tension are useful, but film growth occurs far from equilibrium (ex vi termini). Thus, kinetic processes control the details of film growth and the final film morphology. According to the paper by Burton, Cabrera, and Frank [13], the kinetic rates and processes are controlled by the thermodynamic driving force Ap, defined as the positive difference between the chemical potential of a molecule in the vapor phase and that in the crystal phase. 

Chitosan-collagen composite Isolated aortic valve endothelial cell (VEC) cultures and preferential adhesion to fibronectin, collagen types IV and I over laminin and osteo-pontin. Chitosan-collagen type IV films act as protein precoatings The composite showed improved VEC growth and morphology in comparison to chitosan alone Certain alteration in the properties of chitosan can improve amenability to valve tissue engineering applications Cuy et al.

With an assumption that the surface of the substrate is uniformly covered with the catalyst and that the initial stage of the metal ion reduction proceeds uninterruptedly, further film growth and its surface morphology is influenced exclusively by the parameters of autocatalytic deposition. The rate of metal ion reduction with the appropriate reducing agent at the initial stage of the deposition...

The smoothness or roughness of the substrate surface has a pronounced effect on the film properties. If the substrate surface morphology is not controlled, the film growth and properties may be expected to vary. Generally, a film deposited on a smooth surface will have properties closer to the bulk properties than will a film deposited on a rough surface.
