The electromagnetic and radio-absorbing characteristics offerrite-polymer composites with conductive inclusions based on polyvinylalcohol are investigated. Ni-Zn spinel ferrite powder of 2000NN gradewith composition Ni 0.32 Zn 0.68 Fe 2 O 4 was used as filler. It is shown that theobtained effective absorbers in the frequency range 2-5 GHz peak reflection loss less than ~20 dB. Through analysis ...

Pulsed laser deposition was proved as a suitable method for hydroxyapatite (HA) coating of coaxial poly-ɛ-caprolactone/polyvinylalcohol (PCL/PVA) nanofibers. The fibrous morphology of PCL/PVA nanofibers was preserved, if the nanofiber scaffold was coated with thin layers of HA (200 nm and 400 nm). Increasing thickness of HA, however, resulted in a gradual loss of fibrous character. In addition,...

Amperometric glucose sensors were fabricated using glucose oxidase (GOx) entrapped in zirconium hydrogenphosphate (ZrP), and their performance was evaluated. Reportedly, alpha-ZrP is one of the candidates that are expected to improve the stability of enzymes immobilized on solid surfaces. We intercalated GOxs into ZrP (GOx/ZrP), cast the GOx/ZrP suspension in polyvinylalcohol on a platinum elec...

Although poly-vinyl alcohol (PVA) has certain mechanical drawbacks such as a weak barrier, it widely been used in food packaging over the last many years. To increase suitability of PVA (C2H4O)n and render ideal for packaging, diversity studies have already carried out. In below-mentioned script, we, first time, report use natural product osthol making new composite with enhancing thermal, phys...
