Superparamagnetic nanoparticles, such as magnetite (Fe3O4) and maghemite (γ-Fe2O3), have been used to produce magnetic nanocomposites with several polymeric matrices including magnetic styrene-divinylbenzene nanocomposites. Through the incorporation of these nanoparticles, the nanocomposite presents superparamagnetism, low coercivity, and high magnetic susceptibility. Due to these features, magnetic nanom Read More

Piezoelectric materials are gradually becoming attractive materials for research as far as energy harvesting technologies are concerned. The piezoelectric effect is a pressure-driven phenomenon that is exhibited by various kinds of crystals, ceramics, polymers, and composites. However, polymers are preferred in piezoelectric applications owing to their flexibility and lightweight. They can easily be incorporated into electro Read More

Background: Tramadol HCl (TH) is a centrally acting analgesic that is used to treat moderate to severe pain intestinal disorders. Its use is limited orally due to instability. Objective: The study aims to develop TH Pectin-coated chitosan LDH bionanocomposite beads for colon targeting. Methods: LDH-TH intercalation was done by precipitation reaction and it was used to prepare bionanocomposite beads of TH. The developed bead Read More

Background: Poly (methyl methacrylate) (PMMA) bone cement is widely used in orthopaedic procedures of vertebroplasty (VP) balloon kyphoplasty (BKP) and cemented total joint arthroplasty (TJA). While only very few PMMA bone cement brands are approved (by the appropriate regulatory authority) for VP and BKP, many are approved for cemented TJA. Selection of cement for these applications must be done considering a Read More

Background: The published models were sophisticated and described the expansion in dependence on time only in the first stage. The object was to explain the discrepancy between foaming under pressure release XPS and foaming by heat supply EPS by model calculations. Methods: The rate of expansion of small samples comprising blowing agent and polystyrene was measured by buoyancy in a silicone bath at 110 °C and that Read More

Aims: The objective of the present work is to understand the structural stability (i.e., H-bonding and other weak noncovalent interactions) and electronic features of new model substrates, such as methyl orange (MO), vanadium oxide (V), surfactants as Triton-X100 (TX-100), and their allied substrate-surfactant model complexes (MO-V, MO-TX100, V-TX100, and (MO-V)-X100) with the deployment of density functional theory ( Read More

Background: Polyhydroxyesters prepared from epoxy and organic acids are vitrimers that can rearrange their topology from exchange reactions enhanced by catalysts, forming crosslinked networks that can be deformed and remolded. Objectives: In this work, the curing kinetics and thermal properties of polyhydroxyesters vitrimers based on polyethylene glycol diglycidyl ether (PEGDGE), citric acid (CA), and sebacic acid (SA) i Read More
