Polymer Induced Bundling of F-actin and the Depletion Force [PDF]
, 2003 The inert polymer polyethylene glycol (PEG) induces a "bundling" phenomenon in F-actin solutions when its concentration exceeds a critical onset value C_o. Over a limited range of PEG molecular weight and ionic strength, C_o can be expressed as a function of these two variables.

Polyester Polyols from Waste PET Bottles for Polyurethane Rigid Foams [PDF]
, 2003 This paper describes a modified process to produce polyester polyols from PET wastes derived from the “bottle fraction residue” of the German Dual System (DSD) [11] employing a waste oligoester condensate of the polyesterification process with the ...

Advanced Functional Materials, EarlyView.The developed all‐organic solar cells achieve a power conversion efficiency of 8.7%, more than double the previous record. In addition, bioplastic substrates are used to produce environmentally friendly solar cells with an efficiency of 8.6%. These results are achieved by developing high‐performance organic electrodes without acid doping or high ...

Elucidation of Conformational Hysteresis on a Giant DNA [PDF]
, 2007 The conformational behavior of a giant DNA mediated by condensing agents in the bulk solution has been investigated through experimental and theoretical approaches. Experimentally, a pronounced conformational hysteresis is observed for folding and unfolding processes, by increasing and decreasing the concentration of condensing agent PEG (Polyethylene ...
