We present the covalent modification of a Pani-like conducting polymer (polyaminobenzylamine, PABA) by grafting of a polyelectrolyte brush (poly [2-(methacryloyloxy)-ethyl-trimethylammonium chloride], PMETAC). As PABA ha...

Non-toxic biodegradable linear poly(ester-urethane-urea)s with different hydrophilic character were synthesized from poly(ε-caprolactone) as macrodiol, l-lysine diisocyanate (LDI) and ethyl ester l-lysine or l-ornithine...

Cyclodextrins (CDs)are a family of biodegradable cyclic hydrocarbons composed of α-(1,4)linked glucopyranose subunits, the more common containing 6, 7 or 8 glucose units are named α, β and γ-cyclodextrins respectivel...

Inorganic materials contain remarkable properties for drug delivery, such as a large surface area and nanoporous structure. Among these materials, CaCO3 microparticles (CMPs) exhibit a high encapsulation efficiency and s...

The vapor permeability of modified polyethylene films after long-term exposure to UV radiation and atmospheric factors was studied. The dependences of changes in diffusion characteristics on the type of modifying additiv...

A model for studying the mechanical internal stresses into dielectric materials is developed in the present work. The model takes into account the formalism of inclusions in continuous media. The dielectric material is a...

This study has included a modulation of the rheological properties of asphalt by a catalyst chemical treatment with polycarbonate, and the microwave technique was used at a power of (360) watt at time intervals. Furtherm...

In response to societal demands, the food industry constantly seeks innovations for its products. Active food packaging, developed from biopolymers incorporated with Pickering emulsions, is certainly one of these innovat...

We report a new Ag nanoparticle-dispersed polymer nanocomposite for volume holographic recording through acrylic photopolymerization. The initial grating buildup dynamics at the inhibition stage are measured at various A...

"Material Jetting technology has proven to be very useful in the manufacture of parts with a variety of shapes, consistencies, textures, transparencies and colours, and a great diversity of mechanical properties can be a...

In this article, we report the measurement of underwater aerophobicity, through the captive-bubble method, for different polymeric coatings employed to protect microscale and nanoscale flexible electronic devices for sea...

Abstract The glass transition temperature ( $$\:{T}_{g}$$ ) is a pivotal parameter for amorphous polymers, influencing their behavior under different thermal properties. Assessing $$\:{T}_{g}$$ is crucial for evaluating ...

The fabrication of photonic and electronic structures and devices has directed the manufacturing industry for the last 50 years. Currently, the majority of small-scale photonic devices are created by traditional microfab...

Objective: Lidocaine needs to be administered frequently as it has poor oral bioavailability and it lacks prolong duration of action thus the study was aimed at to devise, develop, and analyze a matrix system transdermal...

IntroductionIt is imperative to minimize protein aggregates in commercial intravenous immunoglobulin (IVIG) therapy as they have been implicated in adverse events and can enhance immunogenicity for patients receiving IVI...

Based on the principles of fractal approach and synergy of structure formation processes modeled in polymer ausketykah based on thermoplastic polyurethane filled with powder of iron (Fe), molybdenum (Mo) and tungsten (W)...

Plastic pollution is a global crisis, with polystyrene (PS) among the most recalcitrant polymers owing to its stable aromatic structure and resistance to natural degradation. Although insect larvae such as mealworms and ...

Amphiphilic comb polymers, like poly(maleic anhydride-alt-1-octadecene) (PMAO), are frequently used to transfer hydrophobic magnetic nanoparticles (NPs) into aqueous media. While it is accepted that the hydrophilization ...

In this study, we present results from path integral molecular dynamics simulations that describe the characteristics of the quantum spatial delocalizations of protons participating in OH bonds in (MeOH)2H+ and in (MeOH)...

We describe polymer diffusion and its temperature dependence in poly(vinyl acetate-co-dibutyl maleate) [P(VAc-DBM)] latex films prepared from 4:1 w/w ratio of VAc:DBM. Two sets of polymers were investigated: one set cont...

Abstract The study is mainly concerned with the physical factors affecting on association of carboxylic acids such as type of solvent, isomers, conjugation and steric effect of acid. The degree of association of carboxyl...

The latest developments in the field of materials to improve the physical and chemical properties is the use of physical modification of polymeric materials. The specimens of polyepoxy and composites on the base metal ox...
