We develop coarse-grained force fields for poly (vinyl alcohol) and poly (acrylic acid) oligomers. In both cases, one monomer is mapped onto a coarsegrained bead. The new force fields are designed to match structural properties such as radial distribution functions of various kinds derived by atomistic simulations of these polymers. The mapping is therefore constructed in a way to take into acc...
in this study silver/poly vinyl alcohol (pva) and silver/poly vinyl pyrrolidone (pvp) nanocomposites were prepared via reduction of silver salt by employing dmf (n, n`- dimethyl formamide) as a reducing agent. effects of protective agents such as pva and pvp were also described here. we show that the acidic ph of pvp solution also affects the interaction between protective agents and silver nan...
Upcycling of plastic waste is approached by designing multifunctional molecules for reactive compatibilization investigations a model polymer blend, here polyethylene (PE) and poly(ethylene- co -vinyl alcohol) (EVOH).
Naltrexone, an opioid receptor antagonist, is commonly used as a relapse prevention medication in alcohol and opiate addiction, but its efficacy and the mechanisms underpinning its clinical usefulness are not well characterized. In the current study, we examined the effects of 50-mg naltrexone compared with placebo on neural network changes associated with substance dependence in 21 alcohol and...
The aim of this research is to develop biocompatible nanofibrous mats using hydroxyethyl cellulose with improved cellular adhesion profiles and stability and use these fibrous mats as potential scaffold for skin tissue engineering. Glutaraldehyde was used to treat the scaffolds water insoluble as well as improve their biostability for possible use in biomedical applications. Electrospinning of ...
In order to enable exploitation of noble metal/poly(vinyl-alcohol) nanocomposites for device fabrication, solutions of poly(vinyl-alcohol) suitable for piezo-driven inkjet printing techniques are identified and discussed in terms of their material properties. The printable poly(vinyl-alcohol) medium is then exploited as a host material through the formation of silver or gold nanoparticles in or...
Here, we present superhydrophobic, hierarchical, and nanostructured cryogels made from cellulose nanofibers (CNFs) nanocrystals (CNCs), double cross-linked with MXene nanosheets poly(vinyl alcohol) (PVA) in the presence of tetradecylamine.
The sol–gel transition and the mechanical properties of a supramolecular poly(vinyl alcohol)–iodine complex can be tuned in time thanks to an “iodine clock”.
Materials for solid photoacoustic breast phantoms based on poly(vinyl alcohol) hydrogels are presented. Phantoms intended for use in photoacoustics must possess both optical and acoustic properties of tissue. To realize the optical properties of tissue, one approach was to optimize the number of freezing and thawing cycles of aqueous poly(vinyl alcohol) solutions, a procedure which increased th...
The mucoadhesive hydrogel film was prepared and optimized for the purpose of local drug delivery to oral cavity for the treatment of oral Candidiasis. The mucoadhesive hydrogel film was prepared with the poly(vinyl alcohol) by freeze/thaw crosslinking technique. 3(2) full factorial design was employed to optimize the formulation. Number of freeze/thaw cycles (4, 6, and 8 cycles) and the concent...
