Depletion gels from dense soft colloids: Rheology and thermoreversible melting
(American Institute of Physics, 2014-08-01)Upon addition of small nonadsorbing linear polymers, colloidal glasses composed of large hard spheres melt and eventually revitrify into the so-called attractive glass regime. We show that, when replacing the hard spheres ... -
Probing Side Chain Dynamics of Branched Macromolecules by Pyrene Excimer Fluorescence
(American Chemical Society, 2016-01-12)Four different pyrene-labeled polymers were prepared by radical copolymerization of n-butyl methacrylate (BMA) and 1-pyrenemethyl methacrylate (PyEG(0)-MA), 1-pyrenemethoxyethyl methacrylate (PyEG(1)-MA), 1-pyrene-methox ... -
Quantifying the Level of Intermacromolecular Interactions in Ethylene-Propylene Copolymers by Using Pyrene Excimer Formation
(American Chemical Society, 2015-07-14)A unique methodology based on fluorescence measurements is introduced to quantitatively measure the actual level of interpolymeric association between ethylene-propylene (EP) copolymers used as viscosity index improvers ... -
The TFOS International Workshop on Contact Lens Discomfort: Report of the Contact Lens Materials, Design, and Care Subcommittee
(Association for Research in Vision and Ophthalmology, 2013-10-18)Examining the role of the contact lens material, design, and the care system is fundamental to understanding contact lens discomfort (CLD). However, a systematic review that tries to determine the governing factors is ... -
Using Pyrene Excimer Fluorescence To Probe the Interactions between Viscosity Index Improvers and Waxes Present in Automotive Oil
(American Chemical Society, 2017-03-28)A new methodology based on pyrene excimer fluorescence (PEF) was applied to quantitatively measure the actual level of intermolecular association between ethylene propylene (EP) copolymers in toluene in the presence of ...
