Manufacturing and acoustical characterization of electrospun PolyVinylPyrrolidone (PVP) Blankets
In this work, new light soundproofing fibrous materials were obtained through electrospinning technique. The sound absorbers were obtained in the form of blankets of thin disks of 10 cm diameter, characterized by fibres with a diameter in order of 2 μm. Different activities involved for acoustical characterization of specimens, in particular to the evaluation of the sound absorption coefficient...
متن کاملIntracellular Ice Formation in Adipose Derived Adult Stem Cells (asc) in the Presence of Polyvinylpyrrolidone (pvp)
The main objective of this work was to optimize the serum free, DMSO free cryopreservation protocol for adipose derived adult stem cells (ASCs), suspended in polyvinylpyrrolidone (PVP) solution, which would help to avoid intracellular ice formation (IIF) – a well known cause of cell death during cryopreservation [1]. Passage 1 (P1) ASCs were cultured in our lab, washed and suspended in a 10% w/...
متن کامل3D Hierarchical Bi2S3 Nanostructures by Polyvinylpyrrolidone (PVP) and Chloride Ion-Assisted Synthesis and Their Photodetecting Properties
A solvothermal method has been employed to synthesize bismuth sulfide (Bi2S3) with three-dimensional (3D) hierarchical architectures. The influences of different types of surfactants and Cl(-) species on the size and morphology were investigated. A possible formation mechanism was also proposed on the basis of time-dependent experiments. The photoresponse properties show that the conductivity o...
متن کاملTemperature and concentration calibration of aqueous polyvinylpyrrolidone (PVP) solutions for isotropic diffusion MRI phantoms
To use the "apparent diffusion coefficient" (Dapp) as a quantitative imaging parameter, well-suited test fluids are essential. In this study, the previously proposed aqueous solutions of polyvinylpyrrolidone (PVP) were examined and temperature calibrations were obtained. For example, at a temperature of 20°C, Dapp ranged from 1.594 (95% CI: 1.593, 1.595) μm2/ms to 0.3326 (95% CI: 0. 3304, 0.334...
متن کاملPolyvinylpyrrolidone (PVP) water solutions as isotropic phantoms for diffusion MRI studies
Introduction As Diffusion Tensor MRI (DTI) and other diffusion MRI applications are becoming more widespread clinically, the need to develop a phantom for diffusion MRI calibration and quality control is essential. Standard MRI phantoms are often suboptimal as diffusion phantoms because they have diffusivities that are too large to be representative of those found in biological tissues. Tofts e...
