Physical Chemistry of Colloids and Surfaces – Final Exam Review 4-30-02
... -In general, most polymers adsorb to surfaces since only a few monomers need to stick to hold the entire chain in place. This leads to a loop-train-tail configuration for homopolymer adsorption. -Polymers can also be attached to surfaces by chemical grafting or through the use of a block copolymer ...

Rearranging Linear Equations
... Rearranging linear equations What is an equation? An equation is an expression of numbers and variables (represented by letters) linked together by an equals sign. Often equations need to be rearranged to isolate one of the variables. This variable is then called the subject of the equation. Example ...
