This paper describes the preparation and characterization of a new type of composite nanoparticle, where the structure consists of a nontoxic hydrogel polymer network that encapsulates a gold shell/silica core. These composite nanoparticles are being developed as photothermally responsive drug-delivery vehicles that undergo structural changes slightly above physiological temperature. A unique p...

Acrylic acid (AA) is used widely in the synthesis of esters essential in the production of paints, adhesives, plastics, and coatings. The minimal systemic toxicity of AA is attributed to its rapid oxidation to acetyl-CoA and CO2 via the vitamin B12-independent beta-oxidation pathway. This oxidation is localized to the mitochondria and preliminary evidence suggests a possible inhibition of mitoc...

The adsorption of macromolecules on solid surfaces is of great importance in the field of nanotechnology, biomaterials, biotechnological, and food processes. In the field of oenology adsorption of wine macromolecules such as polyphenols, polysaccharides, and proteins is much less desirable on membrane materials because of fouling and reduced filtering performance. On the other hand, adsorption ...

Waterborne colloidal polymer coatings are widely used in architectural and agricultural applications where they subject to challenging environments, such as extremes of temperatures relative humidities (RH). This research investigates the effects adding two common co-formulants, poly(acrylic acid) (PAA) xanthan gum (XG), waterborne composite these environments. The mechanical properties resulti...

Contemporary muralism is one of the most widespread manifestations urban art in cities nowadays. Loss colour (fading) due to degradation pictorial materials main deterioration this type artwork. However, application protective coatings considered slow down fading. In study, two acrylic-based were applied selected areas a real mural painted with six different alkyd paints and acrylic paint. The ...

For a long time, large number of sandstone cultural relics have been exposed to the outdoors, and they are facing unprecedented threats. Curing perhydropolysilazane at varied pyrolysis times results in series SiON solids. Fourier transform infrared absorption spectroscopy (FTIR) show that Si−H bond disappears 2163 cm−1, Si−O peaks 460 becoming stronger during Perhydropolysilazane (PHPS) X-ray p...

The pH-responsive frictional behavior of layer-by-layer assembled poly(allylamine hydrochloride) and poly(acrylic acid) multilayers is quantified in different geometric forms of a continuous planar film and anisotropic tube forests. A mechanistic change from surface adhesion dominated frictional behavior to visco/poroelasticity-governed shear occurs for the planar film upon pH-stimulus. This pH...

Water-based anticorrosion resins have gone through many stages of evolution. Despite steady progress, there is still need for improvements. Recent innovations in the area of polymer colloids and hybrid materials offer new opportunities to develop novel coatings for metal protection. By choosing the appropriate technology, it is possible to design acrylic binders with improved barrier properties...

Cathodic electrografting is an efficient technique to impart adhesion to poly(meth)acrylate coatings onto inorganic conducting surfaces. Although this technique was restricted for many years to very few monomers ((meth)acrylonitrile and (meth)acrylates) and to deposition of very thin polymer films, recent developments have overcome these limitations. First of all, classical controlled/living po...
