Morphological characterization of a polymeric microfiltration membrane by synchrotron radiation computed microtomography [PDF]

, 2007
Most commercial polymeric membranes are prepared by phase inversion. The performance of the membranes depends greatly on the morphology of the porous structure formed during the different steps of this process.

Polyvinylidene fluoride (PVDF) Nanofiber Modified Current Collector in Anode-Free Lithium Battery

Indonesian Journal of Applied Physics
In order to coat the layer of the Cu for an anode-free lithium battery (AFLB) and examine AFLB performance, PVDF nanofiber with electrospinning is used. The fabrication time and molecular weight of the nanofiber can be modified.

PVDF composite nanofibers applications

Heliyon, 2022
Polyvinylidene fluoride (PVDF) has special piezo/pyro/ferroelectric, flexibility, low weight, biocompatibility, economical, good chemical/thermal, and high mechanical properties, such as excellent nontoxic fiber/film formation. It has polar and nonpolar phases of α, β, γ, ε, and δ, in which the nonpolar α phase is the most stable one.

E-beam irradiation of poly(vinylidene fluoride-trifluoroethylene) induces high dielectric constant and all-trans conformation for highly ionic conductive solid-state electrolytes

Energy Materials and Devices, 2023
Polymer matrices have limited abilities to dissociate lithium salts and transport ions, thus making most solid-state polymer electrolytes (SPEs) have extremely low ionic conductivities (10−7–10−5 S/cm) at 25 ℃.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
