The illustrated embodiments relate to reducing variable retention time in dynamic random access memory integrated circuit devices. These catalysts with titanium metal centers have high performance characteristics, including high styrene incorporation into ethylenestyrene copolymers. The frame has a top frame member, a bottom frame member, and an intermediate frame member supported in a spaced apart, parallel relation to define a first strap receiving slot and a second strap receiving slot. Crosslinked polymer carrier fluids are identified that are not damaged by contaminants present in the fibers or by degradation products released by premature degradation of the fibers.
