Identify a “multicomponent, soft material” that you find interesting, and would like to discover how it works.
To be acceptable, the material you choose must have a multicomponent formulation with non-trivial mechanical properties.
1. Identify the product or material. You can be as specific as you like – Crest pro-health, Kirkland signature natural peanut butter, “Great Stuff” rodent- blocking foam, whatever.
2. Identify the primary pupose of the product or material – what is it supposed to do, what problem is it solving for its user?
3. Identify the mechanical aspects involved in the product’s function. Must it be sprayable? Must it pour? Spread? Wet a particular material? Must it cling to something? Scrub? Sit without flowing? As best you can, connect these properties to the non-Newtonian flow phenomena we’ve discussed.
4. What chemical tasks must the product perform? Stability (how could it go unstable?) Clean a surface? React with a substrate? Absorb or dissolve a deposit? Coat a surface? Deposit a substance? Kill microbes? Absorb something or release something? Buffer against environmental changes?
5. Does the material undergo any transformations during use? (Phase transitions, does it harden, does it evaporate, …)
6. Identify constraints on the specific product. Must it be edible? FDA- compliant for pharma space? Toxicity? Environmental impact? Cost and availability of ingredients? These limit specific choices from the various classes of “building blocks” used to achieve the rheology, performance, etc.

A vertical vessel a nominal capacity of 5000 gal. is to be mounted on four electronics shear-type load cells. the system is designed so that in extreme case, three of the four loads cell can carry the entire weight. The liquid specific gravity is 1.15. The tare weight of the empty vessel is 5380. shear type load cell are available in the following range 2000lb, 5000lb, 20,000lb, and 30,000lg 1- select a measurement range from the weight system. 2-The electronic load cell readout has four active digits to display the weight. what is the smallest weight that can be display. 3-given a accuracy of 0.1% what is the maximum inaccuracy in lb when the tank is full? 4- given an accuracy of 0.1% what is the maximum inaccuracy in lb wen the tank is 10% full?

What are the main chemical reactions involved in AMD formation?
What is the “initiator reaction” and the “propagation cycle”?
Why is this cyclical nature (regeneration of Fe2+) problematic? How do microbes play a role in these reactions?
What is “yellow boy”? Oxidation of Fe2+ is very slow at low pH values. Why does this reaction occur then in acidic environments?
