    Résumé: La présente étude a été conçue en vue de déterminer si une modification de la surface par PICVD (dépôt chimique en phase vapeur photo-initié) a une incidence différente sur les propriétés physicochimiques du polyéthylèneglycol (PEG) que sur celles du polyvinylalcool (PVA), étant donné leur structure et leurs propriétés chimiques différentes. Les mesures de l’angle de contact ont révélé une augmentation de l’hydrophobicité de la surface des deux polymères après un traitement par PICVD. De plus, l’accroissement de l’hydrophobicité a facilité la dispersion dans les solvants non polaires. Les changements chimiques étaient concentrés près de la surface, comme en témoignent les mesures de spectroscopie infrarouge à transformée de Fourier (FTIR) et de spectroscopie de photoélectrons X (XPS), qui indiquent notamment qu’une oxydation partielle se produit au cours du traitement. Nous discutons de ces résultats du point de vue des différences entre les structures moléculaires du PEG et du PVA, lesquelles modulent la fonctionnalisation et l’hydrophobicité de leur surface. ---------- Abstract: This study was designed to determine if surface modification via photo-initiated chemical vapor deposition (PICVD) affects the physicochemical properties of polyethylene glycol (PEG) and poly(vinyl alcohol) (PVA) differently, given their different chemical structures and properties. Contact angle measurements showed that both polymers increase in surface hydrophobicity after PICVD treatment. Further, the improved hydrophobicity facilitated dispersion into nonpolar solvents. Chemical changes were concentrated near the surface, evidenced by Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) measurements, indicating namely that partial oxidation occurs during treatment. These findings were discussed in the context of the difference of the molecular structures of PEG and PVA, which, in turn, control their surface functionalization and hydrophobicity

    Charge effect of superparamagnetic iron oxide nanoparticles on their surface functionalization by photo-initiated chemical vapour deposition

    Diverse applications of superparamagnetic iron oxide nanoparticles (SPIONs) in the chemical and biomedical industry depend on their surface properties. In this paper, we investigate the effect of initial surface charge (bare, positively and negatively charged SPIONs) on the resulting physicochemical properties of the particles following treatment through photo-initiated chemical vapour deposition (PICVD). Transmission electron microscopy shows a nanometric polymer coating on the SPIONs and contact angle measurements with water demonstrate that their surface became non-polar following functionalization using PICVD. FTIR and XPS data confirm the change in the chemical composition of the treated SPIONs. Indeed, XPS data reveal an initial charge-dependent increase in the surface oxygen content in the case of treated SPIONs. The O/C percentage ratios of the bare SPIONs increase from 1.7 to 1.9 after PICVD treatment, and decrease from 1.7 to 0.7 in the case of negatively charged SPIONs. The ratio remains unchanged for positively charged SPIONs (1.7). This indicates that bare and negatively charged SPIONs showed opposite preference for the oxygen or carbon attachment to their surface during their surface treatment. These results reveal that both the surface charge and stereochemical effects have determinant roles in the polymeric coating of SPIONs with PICVD. Our findings suggest that this technique is appropriate for the treatment of nanoparticles

    Netism : Political philosophy and its impacts

    No full text
    In this paper of Dr. Taraneh Javanbakht, a new philosophical theory based on a new ethical theory is proposed. The focus of Netism is on the limitation of reason in the network of the tendencies of repetition. According to Netism, an agent's act is morally correct if and only if it does not contain the tendencies of repetition to damage poeple and him(her)self. The base of the decrease of these tendencies is not ethical but existential. Altougth not damaging is not equivalent to being useful, but the first one is more fondamental than the second one. The tendency of repetition in not in being useful to others, but in dmaging their lives. Moreover, the ethics in Netism is not a close system, in which the acts are moral. Even if the reason overcomes the tendencies of repetition, it cannot be independent of them. The decrease of the tendecites of damaging eash other's life in a country does not always mean the rationality in the useful phenomena. The disorders in the political behaviors in the countries can be explained by the limitation of the reason in the set of the tendencies of the repetion of damage. These tendencies exist potentially and when they appear, they cause the disorder of the political behaviors. In this condition, some or all of the political rules in a country change by the politicians and the new rules replace them. Some solutions to this problem are proposed in this paper
