The optical properties of polyvinyl (pyrrolidine and alcohol) PV(P/A) blend polymer have been improved using Co-metal as a filler for optoelectronic shielding applications. casting technique solutions was used in order to prepare composite films with different Co-ratios (x: 0-18.5). XRD, FT-IR, SEM, UV-visible spectrophotometry were operated study the structure, morphology, features flexible pl...

Zinc sulfide semiconductor nanoparticles were synthesized in an aqueous solution of polyvinyl pyrrolidone via a simple microwave irradiation method. The effect of the polymer concentration and the type of sulfur source on the particle size and dispersion of the final ZnS nanoparticle product was carefully examined. Microwave heating generally occurs by two main mechanisms: dipolar polarization ...

Chlamydia trachomatis is a very common sexually transmissible infection in both developing and developed countries. A hallmark of C. trachomatis infection is the induction of severe inflammatory responses which play critical roles in its pathogenesis. Antibiotics are the only treatment option currently available for controlling C. trachomatis infection; however, they are efficacious only when a...

Poly(vinyl alcohol) and poly(vinyl pyrrolidone) were blended and films were obtained by casting method. Glutaraldehyde, hydrochloric acid and lactic acid were added to investigate their effect on mechanical properties, swelling and solubility of the blends with the aim to find a possible material candidate for medium or long term implants. Combination of all three additives (lactic acid, glutar...

Lantana camara Linn is one of the plants that can help wound healing process because it contains phenolic, flavonoids, and alkaloids have antibacterial abilities against Staphylococcus epidermidis. but its use still very simple, therefore necessary to develop traditional medicinal preparations in transdermal patches with a combination EC (Ethyl Cellulose) PVP (Poly Vinyl Pyrolidone) polymers. T...

One of the preconditions of biomedical use of iron oxide nanoparticles including magnetite is their stabilization in liquid medium, wherein the covering substances largely determine pharmacological activity and toxicity of such nanoparticles. we obtained nanofluid that contains magnetite nanoparticles stabilized with 2-ethyl-6-methyl-3-hydroxypyridine succinate (Mexidol) and polyvinyl pyrrolido...

Zinc batteries are a more sustainable alternative to lithium-ion due its components being highly recyclable. With the improvements in screen printing technology, high quality devices can be printed with at throughput and precision lower cost compared those manufactured using lithographic techniques. In this paper we describe fabrication characterization of zinc batteries. Different binder mater...

phenylalanine dehydrogenase (phedh; ec 1.4.1.20) is an important enzyme of amino acid dehydrogenases family that increasingly used as a valuable biocatalyst in neonatal screening kits and synthesis of l-phenylalanine. the goal of this literature was to find a suitable purification method for recombinant bacillus badius phedh by practical comparison between chromatographic and polyvinyl pyrrolid...
