Selectivity as a function of membrane thickness: gas separation and pervaporation [PDF]

open access: yes, 1994
In this article, the pervaporation selectivity as a function of the membrane thickness is studied for the dehydration of acetic acid. From this study, it appeared that the selectivity of polysulfone (PSF), poly(vinyl chloride) (PVC), and ...

Thermoresponsive copolymer-grafted SBA-15 porous silica particles for temperature-triggered topical delivery systems

open access: yeseXPRESS Polymer Letters, 2017
A series of poly(N-isopropylacrylamide-co-acrylamide) thermoresponsive random copolymers with different molecular weights and composition were synthesized and characterized by attenuated total reflectance Fourier-transform infrared (ATR-FTIR ...

Ground state non-universality in the random field Ising model [PDF]

open access: yes, 2001
Two attractive and often used ideas, namely universality and the concept of a zero temperature fixed point, are violated in the infinite-range random-field Ising model.

Phase diagram, energy scales and nonlocal correlations in the Anderson lattice model [PDF]

open access: yes, 2011
We study the Anderson lattice model with one f-orbital per lattice site as the simplest model which describes generic features of heavy fermion materials.

The Wigner Solution and QCD Phase Transitions in a Modified PNJL Model [PDF]

open access: yes, 2013
By employing some modification to the widely used two-flavor Polyakov-loop extended Nambu-Jona-Lasinio (PNJL) model, we discuss the Wigner solution of the quark gap equation at finite temperature and zero quark chemical potential beyond the chiral limit,

Picosecond fluctuating protein energy landscape mapped by pressure–temperature molecular dynamics simulation [PDF]

open access: yes, 2007
Microscopic statistical pressure fluctuations can, in principle, lead to corresponding fluctuations in the shape of a protein energy landscape. To examine this, nanosecond molecular dynamics simulations of lysozyme are performed covering a range of ...

Lower critical solution temperature versus volume phase transition temperature in thermoresponsive drug delivery systems

open access: yeseXPRESS Polymer Letters, 2011
One of the most subtle problem in the characterization of thermoresponsive polymers is the evaluation of the relationship between the lower critical solution temperature (LCST) of the linear polymer and the volume phase transition temperature (VPTT) of ...

Tuning the critical solution temperature of polymers by copolymerization [PDF]

open access: yes, 2015
We study statistical copolymerization effects on the upper critical solution temperature (CST) of generic homopolymers by means of coarse-grained Langevin dynamics computer simulations and mean-field theory.

Synthesis and characterization of a novel temperature-pH responsive copolymer of 2-hydroxypropyl acrylate and aminoethyl methacrylate hydrochloric salt

open access: yeseXPRESS Polymer Letters, 2009
In this investigation, a novel temperature-pH responsive copolymer was prepared by the radical copolymerization between 2-hydroxypropyl acrylate (HPA) and aminoethyl methacrylate hydrochloric salt (AMHS).
