What is technological diffusion?
Technology diffusion can be defined as the process by which innovations are adopted by a population. Americans have come to demand state-of-the-art medical technology, despite its astronomical costs, and we place a huge emphasis on medical specialization.
What is the importance of diffusion coefficient?
The diffusion coefficient is an important variable in many diffusion equations that describes how quickly one material can diffuse through another material. Increasing temperature increases the diffusion coefficient, as demonstrated by the equation relating the diffusion coefficient to temperature.
What is an example of technology diffusion?
For example, a society may have adopted the internet faster than it adopted the automobile due to cost, accessibility, and familiarity with technological change.
What is rate of diffusion in technology management?
Diffusion is the process by which a new idea or new product is accepted by the market. The rate of diffusion is the speed with which the new idea spreads from one consumer to the next.
Does diffusion coefficient increase with temperature?
The coefficient of diffusion increases gradually as the temperature of the air increases. The activation energy was calculated by using the Arrhenius equation for all simulators.
What is the difference between technology infusion and technology diffusion?
7. What is the difference between technology infusion and technology diffusion? Technology infusion is a measure of how widely technology is spread throughout the organization. Technology diffusion is a measure of how integrated a technology is within an area or department.
When to use diffusion coefficient in a multi component system?
Diffusion coefficient is generally prescribed for a given pair of species. For a multi-component system, it is prescribed for each pair of species in the system. The higher the diffusivity (of one substance with respect to another), the faster they diffuse into each other.
Which is the correct definition of diffusion coefficient DAC?
chemical diffusion coefficient DA is defined as the self or tracer diffusion coefficient DAC denotes diffusion under a concentration gradient DAdenotes diffusion of tracer A (dilute) in uniform concentration In dilute solution, γA = γH = constant,
What are the diffusivities of Cu self diffusion?
The inset exemplifies the Cu self-diffusion for which a slight, but nevertheless clearly visible deviation from pure Arrhenius behavior appears. With the exception of Pb, the diffusivities at the melting point lie in the 10 −13 m 2 s −1 and 10 −12 m 2 s −1 range.
What is the self diffusion coefficient of argon?
The viscosity coefficient of argon (mol. wt. = 39.94) has the values 1.878 × 10 −4 and 2.270 × 10 −4 dyne sec cm −2 at 240°K and 300°K, respectively. Using Chapman’s equations, calculate the self-diffusion coefficients for argon at these temperatures and one atmosphere pressure.
