Here are some images of liquid distributors, for the shot when the reactor opens up and the gas and liquid enter the reactor. With these liquid distributors the liquid is equally distributed (in the ideal case) over the whole width of the column. This gallery also includes one image of so-called Taylor-flow, which will happen inside the monolith (see “Some clarifying pictures (3)” below).

Here are some images of monolith structures, with which the reactor column is packed. Monoliths increase the surface/volume ratio, and thus improve the contact time between gas and or liquid, so there is more time for the reactants to react with each other, to form products. The gallery also includes schematic views of how the liquid can flow through the monolith and a schematic view of all aspects concerning the monolith.

To make clear the outline of the animation, see this PreViz (Previsualization) made of the images of the second storyboard.

First, you see the reactor. Then there will be a zoom at the upper part of the reactor and the exterior of the reactor will fade, so it can be seen how the liquid and gas enter the reactor (the gas by a funnel and the liquid by a liquid distributor). Then you will see the dripping of the liquid in the gas on the upper part of the monolith. The foremost half of the monolith then will fade away so that Taylor flow can be shown. After that you will follow a bubble on it’s way through the monolith. After this short ‘chase’ you end up zooming in at the surface of the monolith. After the zoom at the surface you can see that the surface consists of zeolite crystals. Then after another zoom the structure is shown of the zeolite (lattice of atoms with clusters of Platina (Pt)). In a cage of a zeolite crystal finally the reaction will take place on the Pt-cluster, and in this case it is the dehydrogenation of propane (propane generates a hydrogen and a propene molecule). Eventually the animation end here or you will travel your way backwards to outside of the reactor.

For more explanation on several terms used in the above, see the “Some clarifying pictures” posts.

Here are some images of reactors @ Chemical plants for the first shot of the animation

The second moodboard is containing images of renders and snapshots of animations that I do like.

A few aspects visualized by the images that I want to highlight are:

- nice use of colors, grey-scale or neutral colors (browns, tans, pastels and darker colors)

- organic geometries – no perfect straight edges or unrealistic polished surfaces

- use of depth

- use of blurriness to indicate where the focus must be

- detail and randomness make it more realistic

- nice illuminating materials to stress a microscopic effect

- devices (e.g. the injection needle) have to look realistic, not as toys, in the image this is done by using materials with right features (reflecting or not, translucent or not)

The first moodboard is containing images of renders and snapshots of animations that I don’t like.

A few aspects visualized by the images that I want to highlight are:

- Use of (childish) colors – rainbow like colors

- Strange use of lightning, shadows are usually not (abundantly ) present at this level

- Exaggerated light effects; some kind of lightning bolt out of the blue or another flash

- Childish geometries, not organic at all

- Too shiny surfaces, the effect is that it begins to look fake

- Too sketchy, if we would want sketchy, we would draw images and not model in 3D

Below my first attempt to visualize the plot of the animation that I’m going to make. The last image is a sketchy one, because the reaction needs further specification before I can visualize it.

3 – Photo of the same support covered with CoCr₂O₄ using the usual method of wet impregnation.

In search of examples for a zoom in/zoom out effect or other things that can be helpful in my project, I stumbled upon this video about new concepts of nano-technology. Some remarks on the video are:

@ 1:40 zoom in effect to nano-scale

@2:26 again a zoom-in effect

@ 4:22 another zoom in effect, which I don’t appreciate, because I think it is too simple; it is done just by adding the new scale in a number in the corner of the screen.

Another video about nano-technology deserves also some attention:

@ 1:00 You can see a visualised structure of nano-tubes, and later on their construction of molecules, also a short visualisation of an animated nano-tube!

@ 4:12 Another visualised nano-tube

@ 5:32 visualisation of equivalent nano-mechanical properties, done by bacteria in a biological sense

@ 9:15 nice animated nano particles are visualised

A video I watched earlier was on the homepage of Nucleus Medical Media (see earlier post). This video uses certain techniques that I can also use in my animation. I will try to illustrate these effects by discussing  snapshots taken from the video, in a following post.
