    Catalyst Modelling

    I have little knowledge of MATLAB. I am trying to model the concentration profile along the photocatalyst film thickness in a photoreactor. Mass Transport takes place by diffusion and the rate of generation of component is given by rA. Boundary conditions: Concentration of the component that is...

    Gibbs' theorem and partial molar volume

    In the chemical engineering text of Smith, VanNess, and Abbott, there is a section on partial molar volume. It states that Gibbs theorem applies to any partial molar property with the exception of volume. Why is volume different? In other words, when evaluating the partial molar volume of a...

    Non Corrosive pipes in compost

    So with our initial prototype for our anaerobic digester, we weren't able to sustain the right temperature inside the tanks. One idea we came up with is to use the heat from the compost bins that is only within 10-20 feet from our tanks. We plan to circulate the fluid inside the digestion tanks...

    Optimal amount of CO2 to purge air in a device

    <Moderator's note: Moved from a homework forum.> Dear team, I wish to use CO2 to de-air a device by exploiting the physical properties of CO2 as a heavier, more dense gas to air and therefore displace air in a very thin tube that has a nozzle at the end where both air and CO2 can escape. I wish...

    Chemical industry data

    I am curious about production amounts and prices for an annual period, for a few thousand commodity or common chemicals. I noticed a couple chemical intelligence services but they seem out of the price range for an amateur researcher. What kinds of sources are available to look further?

    Re: The electrical excitation of quantum dots

    We most often witness the presentation of quantum dots in viles or containers which are excited via UV light. I am more interested in their electrical excitation. Could I simply take a sample of QDs from one of those viles and passing an electrical current through that sample excite the...
