	abstract = {Biological tissues are combination of liquids and fibrous solids, therefore polymer hydrogels can be used as model heat transfer system for soft tissues. The 3D network structure of the polymer prevents the convection and the dominant mechanism becomes heat conduction. The main purpose of the present work is to study the effect of network structure on the thermal conduction behavior of soft gels. Cylindrical poly(N-isopropylacrylamide) gel which shows lower critical solution temperature below which the system is completely miscible, whereas above LCST phase separation accours (LCST, [1]). The LCST temperature of the p(NIPA) gel is denoted by Tph throughout this article and is equal to 35 °C. One dimensional heat transfer through the length of the gel cylinder has been experimentally and theoretically studied. The temperature at the bottom of the gel cylinder was suddenly raised above the phase transition temperature. That part of gel cylinder becomes opaque where the temperature exceeds Tph. This defines a visible front that moves forward in the opposite direction to temperature gradient. It was found that our novel technique can be successfully applied to determine heat conductivity and heat diffusivity of loosely cross-linked hydrogels. The kinetics of the moving turbid front was determined and analyzed on the basis of standard 1-d transient heat equation and Stefan's law [2]. It was found that the presence of network structure increases thermal diffusivity compared to pure water. It was also observed that latent heat influences thermal diffusivity. © 2014 Elsevier Masson SAS. All rights reserved.},

		for biomedical applications and enhancing the durability of the 
		coating shells. FTIR-ATR measurements reveal two types of 
		interaction of PAM with MNPs: hydrogen bonding and inner-sphere 
		metal-carboxylate complex formation. The mechanism of the latter 
		is ligand exchange between uncharged -OH groups of the surface 
		and -COO- anionic moieties of the polyelectrolyte as revealed by 
		adsorption and electrokinetic experiments. The aqueous 
		dispersion of PAM@MNP particles (magnetic fluids - MFs) tolerate 
		physiological salt concentration at composition corresponding to 
		the plateau of the high-affinity adsorption isotherm. The 
		plateau is reached at small amount of added PAM and at low 
		concentration of non-adsorbed PAM, making PAM highly efficient 
		for coating MNPs. The adsorbed PAM layer is not desorbed during 
		dilution. The performance of the PAM shell is superior to that 
		of polyacrylic acid (PAA), often used in biocompatible MFs. This 
		is explained by the different adsorption mechanisms, namely 
		metal-carboxylate cannot form in the case of PAA. Molecular-
		level understanding of the protective shell formation on MNPs 
		presented here improves fundamentally the colloidal techniques

	abstract = {Magnetite nanoparticles (MNPs) were prepared by alkaline hydrolysis of Fe(II) and Fe(III) chlorides. Adsorption of polyacrylic acid (PAA) on MNPs was measured at pH=6.5+/-0.3 and I=0.01M (NaCl) to find the optimal PAA amount for MNP stabilization under physiological conditions. We detected an H-bond formation between magnetite surface groups and PAA by ATR-FTIR measurements, but bonds of metal ion-carboxylate complexes, generally cited in literature, were not identified at the given pH and ionic strength. The dependence of the electrokinetic potential and the aggregation state on the amount of added PAA at various pHs was measured by electrophoretic mobility and dynamic light-scattering methods. The electrokinetic potential of the naked MNPs was low at near physiological pH, but PAA adsorption overcharged the particles. Highly negatively charged, well-stabilized carboxylated MNPs formed via adsorption of PAA in an amount of approximately ten times of that necessary to compensate the original positive charge of the magnetite. Coagulation kinetics experiments revealed gradual enhancement of salt tolerance at physiological pH from approximately 0.001M at no added PAA up to approximately 0.5M at 1.12mmol/g PAA. The PAA-coated MNPs exert no substantial effect on the proliferation of malignant (HeLa) or non-cancerous fibroblast cells (MRC-5) as determined by means of MTT assays.},
