A Molecular Picture for the Thermo-Reversibility of Gels Formed by Isophthalic Acid-Ended Telechelic Polymers [PDF]

, 2015
We demonstrate that isophthalic acid-ended telechelic poly(1,5-cyclooctadiene)s (A-PCODs) form thermo-reversible gels in non-polar solvent with a unique molecular mechanism for their thermo-reversibility.

Thermoreversible Associating Polymer Networks: I. Interplay of Thermodynamics, Chemical Kinetics, and Polymer Physics

, 2009
Hybrid molecular dynamics/Monte Carlo simulations used to study melts of unentangled, thermoreversibly associating supramolecular polymers. In this first of a series of papers, we describe and validate a model that is effective in separating the effects ...

Statistical Thermodynamics of Clustered Populations [PDF]

, 2014
We present a thermodynamic theory for a generic population of $M$ individuals distributed into $N$ groups (clusters). We construct the ensemble of all distributions with fixed $M$ and $N$, introduce a selection functional that embodies the physics that ...

Recurrent progressive anterior segment fibrosis syndrome following a descemet-stripping endothelial keratoplasty in an infant with congenital aniridia

Indian Journal of Ophthalmology, 2014
Progressive anterior segment fibrosis syndrome (ASFS), after intraocular surgery in older children (≥9 years) and adults with congenital aniridia, is described in the literature.

Reversible gelation and dynamical arrest of dipolar colloids

, 2007
We use molecular dynamics simulations of a simple model to show that dispersions of slightly elongated colloidal particles with long-range dipolar interactions, like ferrofluids, can form a physical (reversible) gel at low volume fractions.

Tuning the critical gelation temperature of thermo-responsive diblock copolymer worm gels [PDF]

, 2014
Amphiphilic diblock copolymer nano-objects can be readily prepared using reversible addition–fragmentation chain transfer (RAFT) polymerization. For example, poly(glycerol monomethacrylate) (PGMA) chain transfer agents (CTA) can be chain-extended using 2-

Influence of multiple sclerosis, age and degree of disability, in the position of the contrast sensitivity curve peak

Indian Journal of Ophthalmology, 2014
Context: Contrast sensitivity (CS) function is one of the most important tests available for evaluating visual impairment. Multiple sclerosis (MS) can produce highly selective losses in visual function and psychophysical studies have demonstrated CS ...

Molecular mechanisms driving the microgels behaviour: a Raman spectroscopy and Dynamic Light Scattering study

, 2019
Responsive microgels based on poly(N-isopropylacrylamide) (PNIPAM) exhibit peculiar behaviours due to the competition between the hydrophilic and hydrophobic interactions of the constituent networks. The interpenetration of poly-acrilic acid (PAAc), a pH-

Stimulus-responsive block copolymer nano-objects and hydrogels via dynamic covalent chemistry [PDF]

, 2017
Herein we demonstrate that dynamic covalent chemistry can be used to induce reversible morphological transitions in block copolymer nano-objects and hydrogels.
