Chemical vapor deposition

used steel pressure tanks: Vapor Drawings - An internationally known contemporary artist, makes drawings and sculpture by painting with chemicals on glass and paper. He “paints” with these chemicals by vaporizing them in a vacuum tank. The artist purchased a steel pressure tank and placed it horizontally in his studio. He customized this tank to become a vacuum chamber. The artist places glass and paper on one side of the tank and small containers of chemicals on the other side. He takes…

The term “Snowflake Generation”, especially in the present day, is thrown around in heaps on Youtube video comments, Facebook comments, article comments, and just about anywhere someone can voice their opinions. The definition of Snowflake Generation, is “the generation of people who became adults in the 2010s, viewed as being less resilient and more prone to taking offence than previous generations,” According to the Collins English Dictionary. The modern usage and definition of Snowflake…

Introduction Vapor pressure is the pressure of a vapor (gas) at equilibrium; equilibrium occurs when there is no net change between the amount of liquid and the amount of vapor because they balance each other. When the temperature of water becomes extremely low, as it does in this experiment, the rate of vaporization does not matter. The objective of this experiment is to determine the experimental heat of vaporization and compare it to the accepted heat of vaporization of water (40.7 kj/mol).…

another alcohol should be used. A volatile liquid is a liquid that evaporates readily at room temperature or a liquid that has a measurable vapor pressure. Vapor pressure is the equilibrium pressure resulting in the evaporation of a liquid in a closed container.1 It is important to know the vapor pressure of a volatile liquid because the higher the vapor pressure, the faster the liquid evaporates.2 So…

barrier from the decaying world below. Regardless of their class, individuals underwent this transformation for a chance at a prosperous life. However, that was 100 years ago and although, the higher altitude offered protection, it provided excess water vapor that was accumulating in people’s lungs and, drowning them. Cirrus looked out over…

on a molecular level in the (DIWF) with the aid of experimental evidence. The writer is keen on proving that the fog produced in the (DIWF) demonstration is actually from the bulk water onto which the dry ice is placed and not the atmospheric water vapor. In a bid to understand the mechanism of the formation of fog, the writer employs a model, where the interaction of dry ice with other liquids is closely observed, and the effectiveness of experimental conditions in producing fog…

Introduction/Background -What is the nature of the product or technology? The nature of 3d printing is nearly any area you can think of applying it to. -What is its development history? Rapid prototyping came about in the late 1980s and early 1990s. ‘Rapid prototyping ‘paved the road for all the 3d printing companies out today. (Rapid prototyping created prototypes for a manufacturer to create a prototype of a product with plastics before executing their plans and mass producing them from…

may not have been consistent throughout the reaction, leading to an error in the observed rate, and consequently an error in the activation energy. A final potential error could come from the decision not to account for the vapor pressure of the water, or for the change in vapor pressure when the temperature of the water was increased in trial 4, this could have indicated a higher rate of production of O2 than was actually…

Both 3D printers follow the Fused Deposition Modeling (FDM) process. The Printrbot 1404 is capable of printing both Acrylonitrile Butadiene Styrene (ABS) and Polylactic Acid (PLA) plastics on a heated printed bed. The Printrbot extruder is able to move on the x, y, and z axis, while its print…

3D Printing and the Additive Manufacturing Process Additive manufacturing (AM) is a process where an object is created by adding layer-upon-layer of material. This basic process requires the use of a computer, CAD software, the material(s) and the appropriate machine to fabricate the end result. AM has been used in many applications. At first, it was used in Rapid Prototyping (RP). Today, AM is used to create end-products used in many different applications, from aerospace, automotive and…
