Optical Properties of (PVA-PAA-Ag) Nanocomposites

In this paper, the effect of silver nanoparticles on optical properties of (PVA-PAA) nanocomposites has been investigated. The silver nanoparticles were added to the polymers (polyvinyl alcohol 80 wt.% and poly-acrylic acid 20 wr.%) with weight percentages of (0, 2, 4, 6) wt.%. The optical properties of nanocomposites were measured in the wavelength range (200-800) nm. The experimental results ...

Phylogeographic Analyses Strongly Suggest Cryptic Speciation in the Giant Spiny Frog (Dicroglossidae: Paa spinosa) and Interspecies Hybridization in Paa

Species identification is one of the most basic yet crucial issues in biology with potentially far-reaching implications for fields such as conservation, population ecology, and epidemiology. The widely distributed but threatened frog Paa spinosa has been speculated to represent a complex of multiple species. In this study, 254 individuals representing species of the genus Paa were investigated...

Alkaline Earth Element Adsorption onto PAA-Coated Magnetic Nanoparticles

In this paper, we present a study on the adsorption of calcium (Ca2+) onto polyacrylic acid-functionalized iron-oxide magnetic nanoparticles (PAA-MNPs) to gain an insight into the adsorption behavior of alkaline earth elements at conditions typical of produced water from hydraulic fracturing. An aqueous co-precipitation method was employed to fabricate iron oxide magnetic nanoparticles, whose s...
