  1. Hace 4 días · Quorum quenching (QQ) has emerged as an effective biofouling mitigation approach in membrane bioreactors. This study presents new approaches for preparing and characterizing polyvinyl alcohol (PVA) and alginate beads for QQ applications. The effects of change in concentration of PVA, crosslinking solution composition, and the impact of mixture dissolution method on physicochemical, acyl ...

  2. Hace 3 días · This study evaluates the mechanical properties and formulation of dental restoration material comprised of cellulose acetate (CA) from water hyacinth and chitosan (C) from white shrimp shells. The research phases included extraction, formulation, functional group testing, antibacterial, toxicity, water absorption and solubility, compressive, shear, tensile, hardness, microleakage, thermal ...

  3. Hace 4 días · The current polyvinyl chloride (PVC) gel flexible actuators are facing challenges of high input voltage and an insufficient elastic modulus. In this study, we conducted a detailed study on the properties of PVC gel prepared by introducing the modifier polyvinyl chloride-vinyl acetate (P(VC-VA)). We compared a modified PVC gel with the traditional one in terms of the relative dielectric ...

  4. Hace 4 días · Polyaniline was synthesized in an acidic medium by chemical oxidation of the monomer described in the literature. 24 A total of 6-mL aniline was dissolved in 200-mL (1 M) HCl in a beaker, which was kept in an ice bath (0–5°C). In a separate beaker, 11.4 g of ammonium peroxydisulfate was dissolved in 100 mL of DI water.

  6. Hace 3 días · This study focused on creating water-soluble laundry bags to reduce contact with contaminated items. The bags consisted of a composite with 60 wt% polyvinyl alcohol (PVA), 40 wt% pregelatinized starch (P-St), and various amounts of polyethylene glycol (PEG). Blown film extrusion was used to produce blend formulations.

  7. Hace 3 días · Polyvinyl alcohol (PVOH) is a hydrophilic linear polymer that forms copolymers of vinyl alcohol and vinyl acetate. It is prepared by alkaline hydrolysis. It is known to possess high mechanical strength, biocompatibility, and non-toxicity.
