The degree of meat adhesion to different kinds of plastic casings was examined in retort sterilized fish sausages. It was found that the plastic casings of great wettability such as polyvinylidene chloride, polyvinylidene fluoride, polyester and polyamide brought about greater meat adhesion than the ones of low wettability such as polyethylene and polypropylene. If polyethylene casing was modif...

Polyvinylidene fluoride (PVDF) is considered to be one of the most promising candidates for next-generation wearable sensors; however, sensing ability PVDF worth expanding beyond its ferroelectricity. In this work, used as matrix material humidity detection by adding two other ingredients: lithium chloride (LiCl) and polyvinyl alcohol (PVA), optimal concentrations LiCl PVA are found systematic ...

Magnetoelectric 0-1 composites comprising CoFe2O4 (CFO) nanoparticles in a polyvinylidene fluoride (PVDF) polymer-fibre matrix have been prepared by electrospinning. The average diameter of the electrospun composite fibres is ∼325 nm, independent of the nanoparticle content, and the amount of the crystalline polar β phase is strongly enhanced when compared to pure PVDF polymer fibres. The piezo...

Highly-flexible thermoelectric fabrics were fabricated based on a layered structure, composed of a thin active layer of self-assembled tellurium nanorods and a substrate layer of polyvinylidene fluoride. The resulting thermoelectric fabrics show a high room temperature power factor of 45.8 μW m(-1) K(-2), which opens a new avenue to fabricate highly-flexible sustainable energy sources.

In the published manuscript, "Thermal Stability and Magnetic Properties of Polyvinylidene Fluoride/Magnetite Nanocomposites. Materials 2015, 8(7), 4553-4564" [1], we detected that in three places the explanations were slightly incorrect. We apologize for any inconvenience this may have caused. [...].

We report the cases of two patients diagnosed with Morgagni hernia who presented with nonspecific abdominal symptoms. Both underwent laparoscopic surgery that used a dual-sided mesh, polyvinylidene fluoride (PVDF; Dynamesh IPOM®). The procedures were successful and both patients were discharged with no complications. There was no recurrence in 18 months of follow up.Herein is the report of thes...

Piezomaterials are known to display enhanced energy conversion efficiency at nanoscale due to geometrical effect and improved mechanical properties. Although piezoelectric nanowires have been the most widely and dominantly researched structure for this application, there only exist a limited number of piezomaterials that can be easily manufactured into nanowires, thus, developing effective and ...

The spin state of [Fe(H2B(pz)2)2(bipy)] thin films is mediated by changes in the electric field at the interface of organic ferroelectric polyvinylidene fluoride with trifluoroethylene (PVDF-TrFE). Signatures of the molecular crossover transition are evident in changes in the unoccupied states and the related shift from diamagnetic to paramagnetic characteristics. This may point the way to the ...
