A detailed chemical kinetics mechanism was developed to model silicon oxide clustering during high density plasma chemical vapor deposition of SiO2 films from silane-oxygen–argon mixtures. An inductively coupled plasma reactor was modeled in a one-dimensional multicomponent two-temperature framework. Spatial distributions of species concentrations were calculated. The effects of discharge param...

The mechanism of droplet drying is a widely concerned fundamental issue since controlling the deposition morphology of droplet has significant influence on printing, biology pattern, self-assembling and other solution-based devices fabrication. Here we reveal a striking different kinetics-controlled deposition regime beyond the ubiquitous coffee-ring effect that suspended particles tend to kine...

This article discusses the growth of silicon and related materials using ultra-high vacuum chemical vapor deposition (UHV/CVD). This growth technique is well suited for deposition of strained epitaxial layers and also layers with metastable concentrations of impurities such as boron and carbon. In UHV/CVD, growth kinetics and the incorporation of various atoms other than silicon are determined ...

Deposition of minerals, particularly calcium phosphates such as hydroxyapatite, is an important process in the formation hard tissues bone. Herein, a new, affordable, straightforward and nondestructive method based on complex capacitance spectroscopy, application electrochemical impedance described which allows repeated real-time measurements same sample throughout phosphate deposition process....

A moving, solidifying interface that grows by the instantaneous adsorption of a diffusing solute can be described by equations analogous to those of the classical one-sided Stefan problem for solidification. However, the behavior of precipitate growth by material deposition can depend on both surface kinetics and bulk drift of the depositing species. We generalize the Stefan problem and its int...

This contribution presents results on the parameter estimation of rate constants and optical response factors in a reduced order surface kinetics ~ROSK! model, which has been developed to describe the decomposition kinetics of the organometallic precursors involved and their incorporation into the film deposition. As a real-time characterization technique, we applied p-polarized reflectance spe...

We report the development of IgA nephropathy (IgAN) following full myeloablative allogeneic hematopoietic cell transplantation in two patients with human leukocyte antigen (HLA) matched sibling donors, unrelated to active or chronic graft-versus-host disease. Both recipients had elevated urinary levels of galactose-deficient IgA1, and one donor-recipient pair had elevated serum levels of galact...
