Charge Characterization Of An Electrically Charged Fiber Via Electrostatic Force Microscopy [PDF]

open access: yesJournal of Engineered Fibers and Fabrics, 2006
The charge of a corona charged electret fiber as well as an uncharged glass fiber was characterized via Electrostatic Force Microscopy (EFM). Electrostatic force gradient images were obtained by monitoring the shifts in phase between the oscillations of ...

Scalable Fabrication of MOF Glass Membranes for Gas Separation via Stepwise Phase Transition. [PDF]

open access: yesAdv Sci (Weinh)
Metal‐organic framework (MOF) glass membranes, with their excellent processability and permanent pore structure, have great potential for gas separation applications. However, during large‐scale fabrication, defects and obvious cracks are prone to occur due to the limitations of powder processing.

Quantitative characterization of dielectric properties of nanoparticles using electrostatic force microscopy

open access: yesAIP Advances, 2020
We use a new method based on Electrostatic Force Microscopy (EFM) to perform quantitative measurements of the dielectric constants of individual carboxylated as well as non-functionalized polystyrene nanospheres. The EFM data record the oscillation phase
