Multiscale Modeling of Chemical Vapor Deposition (CVD) Apparatus: Simulations and Approximations

We are motivated to compute delicate chemical vapor deposition (CVD) processes. Such processes are used to deposit thin films of metallic or ceramic materials, such as SiC or a mixture of SiC and TiC. For practical simulations and for studying the characteristics in the deposition area, we have to deal with delicate multiscale models. We propose a multiscale model based on two different softwar...

An Apparatus to Produce Gas Mixtures with Controlled CO(2), O(2), and Water Vapor Concentrations.

An apparatus to produce continuous gas mixtures for use in measurements of plant gas exchange is described. A wide range of CO(2) and water vapor concentrations can be provided and O(2) concentration can be varied from 0 to 21%. Changes in the concentrations of the components are accomplished conveniently, rapidly, and independently. With occasional adjustments, CO(2) and O(2) concentrations ca...

An Improved Apparatus For Measuring the Growth of Ice Crystals from Water Vapor

We describe an apparatus designed for obtaining precise measurements of the growth rates of ice crystals from water vapor over a range of experimental conditions. Our aim is to produce clean, high-quality test crystals in a well controlled environment for investigating the detailed molecular dynamics that controls the basic physics of ice crystal growth. In this paper we describe the nucleation...

Golgi's apparatus

Golgi reported an " internal reticular apparatus " in neurons — a structure now known as the Golgi apparatus. Although this is by far his best-remembered work, Golgi made many other important scientific discoveries in his lifetime (1843–1926), and in 1906 shared the Nobel prize for Physiology or Medicine with Santiago Ramón y Cajal for their studies on the structure of the nervous system. As we...
