The present study was undertaken to develop a suitable transdermal matrix patch of Metoprolol tartrate with different proportions of polyvinyl pyrrolidone (PVP) and chitosan crosslinked with glutaraldehyde (GA). The prepared transdermal patches were subjected to different physicochemical evaluations such as thickness, tensile strength, folding endurance, drug content, swellability, surface pH, ...

Here, five different capping agents’ polyethylene glycol (PEG), cetyltrimethylammonium bromide (CTAB), polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), and oleylamine (OAm) are used to form copper nanoparticles (Cu-NPs), along with their electrocatalytic oxygen evolution reaction (OER) properties. The produced Cu-NPs’ mono-dispersity interactions PEG, CTAB, PVA, PVP, OAm were examined. mean...

in the present study, tenorite (cuo) nanoparticles have been assayed for their catalytic properties. the decontamination reaction of chloro ethyl ethyl sulfide (cees) as an surrogate of sulfur mustard simulant have been accomplished on the surface of cuo nps with different weight ratios at ambient temperature and monitored by gas chromatography equipped with flame ionization detector (gc-fid) a...

We reported on uric acid (UA) detection using a new fluorescence-based assay: poly-(vinylpyrrolidone) templated copper nanoclusters (PVP-CuNCs) with uricase in an aqueous medium, such as human urine uricase. These were synthesized simple wet chemical method and their morphological optical properties examined the aid of high-resolution transmission electron microscopy absorbance/emission spectro...

Abstract CS/PVP blend embedded by Sr-hexaferrite nanoparticles as a novel composite material to improve the optical and magnetic properties of samples. This work aimed study compare functional physical film after before adding SrFe 12 O 19 with different weight percentages form nanocomposite chemical formula CS/PVP/x Wt% ; x = 1, 3, 5 7. was prepared successfully using citrate auto-combustion m...

This paper introduces a concept that allows the creation of low-resistance composites using a network of compliant conductive aggregate units, connected through contact, embedded within the composite. Due to the straight-forward fabrication method of the aggregate, conductive composites can be created in nearly arbitrary shapes and sizes, with a lower bound near the length scale of the conducti...

The solution-cast method was used to synthesize magnesia (MgO) nanoparticles filled poly(vinyl alcohol) (PVA) and pyrrolidone) (PVP) blend matrix (80/20 wt %) based polymeric nanocomposite (PNC) films (i.e., [PVA–PVP]–x % MgO; x = 0, 0.06, 0.3, 0.6, 3.1, 6.25). Most of these PNC materials structures are amorphous, according an X-ray diffraction investigation. surface smooth homogeneous under SE...

Matrix type transdermal therapeutic systems (TTS) of glibenclamide were formulated using polymers Eudragit RL 100, ethyl cellulose, PVP K-30, and polyvinyl acetate, and citral was used as the penetration enhancer. The polymer films were formulated with Eudragit RL 100 and PVP K-30 in different ratios and subsequently subjected to ex vivo studies (drug permeation through rat skin) followed by in...
