Determine the height of the energy barrier (in j) that is necessary to keep a suspension of polystyrene nanospheres of diameter 100 nm from being flocculated. the surface charge on these particles is - 2 mv, in aqueous solution at 30 c. it is expected that the suspension may be exposed to temperatures as high as 120 f. for reference, we need a stability ratio of at least 104 to ensure no flocculation

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.
