Surface charges toolkit for gravity [PDF]

open access: yesInternational Journal of Modern Physics D, 2020
These notes provide a detailed catalog of surface charge formulas for different classes of gravity theories. The present catalog reviews and extends the existing literature on the topic. Part of the focus is on reviewing the method to compute quasi-local surface charges for gauge theories in order to clarify conceptual issues and their range of ...

From Raw to Finished Cotton—Characterization by Interface Phenomena

open access: yesAUTEX Research Journal, 2023
Interface phenomena that occur at the solid–liquid interface, such as wettability, adsorption, and particle aggregation, depend on the kind and magnitude of the solid surface free energy and electrokinetic properties found in water solutions.

Do Surface Charges on Polymeric Filters and Airborne Particles Control the Removal of Nanoscale Aerosols by Polymeric Facial Masks?

open access: yesToxics, 2023
The emergence of facial masks as a critical health intervention to prevent the spread of airborne disease and protect from occupational nanomaterial exposure highlights the need for fundamental insights into the interaction of nanoparticles (

On the Colloidal Stability of Nitrogen-Rich Carbon Nanodots Aqueous Dispersions

open access: yesC, 2019
The present survey reports on the colloidal stability of aqueous dispersions of nitrogen-rich carbon nanodots (N-CDs). The N-CDs were synthesized by thermally induced decomposition of organic precursors and present an inner core constituted of a ...

Unraveling the “U-Shaped” Dependence of Surface Flashover Performance on the Surface Trap Level

open access: yesIEEE Access, 2019
The effects of surface traps on surface flashover remain controversial. To clarify the relation between surface flashover and surface trap level, in this work, the surface trap level of epoxy composites was modified by nanoparticles incorporation ...

Cell Surface Charge Mapping Using a Microelectrode Array on ITO Substrate

open access: yesCells, 2023
Many cellular functions are regulated by cell surface charges, such as intercellular signaling and metabolism. Noninvasive measurement of surface charge distribution of a single cell plays a vital role in understanding cellular functions via cell ...

The charge of glass and silica surfaces [PDF]

open access: yesThe Journal of Chemical Physics, 2001
We present a method of calculating the electric charge density of glass and silica surfaces in contact with aqueous electrolytes for two cases of practical relevance that are not amenable to standard techniques: surfaces of low specific area at low ionic strength and surfaces interacting strongly with a second anionic surface.

Analysis of current density and related parameters in spinal cord stimulation [PDF]

open access: yes, 1998
A volume conductor model of the spinal cord and surrounding anatomical structures is used to calculate current (and current density) charge per pulse, and maximum charge density per pulse at the contact surface of the electrode in the dorsal epidural ...
