Poly vinyl acetate (PVA)-based titania (TiO2)–carbon nanotube composite nanofibers (PVA-TCCNs) with various PVA-to-solvent ratios and PVA-based TiO2 composite nanofibers (PVA-TN) were synthesized using an electrospinning process, followed by thermal treatment. The photocatalytic activities of these nanofibers in the degradation of airborne monocyclic aromatics under visible-light irradiation we...

The myocardial oxygen consumption (MVO(2)) to left ventricular pressure-volume area (PVA) relationship is assumed unaltered by substrates, despite varying phosphate-to-oxygen ratios and possible excess MVO(2) associated with fatty acid consumption. The validity of this assumption was tested in vivo. Left ventricular volumes and pressures were assessed with a combined conductance-pressure cathet...

the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

The preparation of biodegradable plastics based on polyvinyl alcohol (PVA)-taro starch as an alternative to synthetic has been conducted. aim this research was identify the effect taro composition production plastic and their characteristics in aquatic environment. solution casting method used produce plastic. PVA dissolved hot distilled water, (0; 0.5; 1.5; 2.5; 3.5 g) another chamber filled w...

Peppers are consumed all over the world due to the flavor, aroma, and color that they add to food. Additionally, they play a role in human health, as they contain a high concentration of bioactive compounds and antioxidants. The treatments used were an absolute control, Cs-PVA, and four treatments with 0.02, 0.2, 2, and 10 mg (nCu) g-1 (Cs-PVA). The application of Cu nanoparticles in chitosan-P...

Abstract One of the main challenges in hyperthermia treatment is how to improve heating performance nanoparticles with high specific loss power (SLP). To tackle this challenge, magnetite (MNPs) and coated polyvinyl alcohol (PVA@MNPs) were fabricated via ultrasonic-assisted coprecipitation technique. The obtained characterized by using FT-IR, TEM, TGA, XRD, ICP-OES, DLS, zeta potential, VSM UV–V...

BACKGROUND This study sought to prepare a new PVA/n-HA/PA66 composite to investigate the repair of articular cartilage and subchondral defects in rabbit knee joints. METHODS A 5 × 5 × 5 mm-sized defect was created in the patellofemoral joints of 72 healthy adult New Zealand rabbits. The rabbits were then randomly divided into three groups (n = 24): PVA/n-HA+PA66 group, polyvinyl alcohol (PVA)...

A technique for the selective measurement of diffusive gradients in thin-films (DGT) for free Cu2+ ions was developed using a 0.030 M solution of polyvinyl alcohol (PVA) as the liquid binding phase with the liquid-type DGT devices (PVA DGT). The PVA DGT had a substantial binding capacity at pH 5.6 - 8.6 and concentrations of competitive Na+ up to 0.7 M. The measurements of PVA DGT and cupric io...

Chitosan is a natural polymer, which has been used in agriculture to stimulate crop growth. Furthermore, it has been used for the encapsulation of nanoparticles in order to obtain controlled release. In this work, the effect of chitosan-PVA and Cu nanoparticles (Cu NPs) absorbed on chitosan-PVA on growth, antioxidant capacity, mineral content, and saline stress in tomato plants was evaluated. T...

Polyvinyl alcohol (PVA) demonstrates chemical stability and biocompatibility and is widely used in biomedical applications. The porous bamboo charcoal has excellent toxin absorptivity and has been used in blood purification. In this study, bamboo charcoal nanoparticles (BCNPs) were acquired with nano-grinding technology. The PVA and PVA/BCNP nanocomposite membranes were prepared and characteriz...
