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 ...

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 ...

On the validity of the “thin” and “thick” double-layer assumptions when calculating streaming currents in porous media [PDF]

open access: yes, 2012
We find that the thin double layer assumption, in which the thickness of the electrical diffuse layer is assumed small compared to the radius of curvature of a pore or throat, is valid in a capillary tubes model so long as the capillary radius is >200 ...

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 ...

Light-induced charged slippery surfaces

open access: yesScience Advances, 2022
Slippery lubricant-infused porous (SLIPS) and superhydrophobic surfaces have emerged as promising interfacial materials for various applications such as self-cleaning, anti-icing, and antifouling. Paradoxically, the coverage/screening of lubricant layer on underlying rough matrix endows functionalities impossible on superhydrophobic surfaces; however ...

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 ...

Effects of image charges, interfacial charge discreteness, and surface roughness on the zeta potential of spherical electric double layers

open access: yes, 2012
We investigate the effects of image charges, interfacial charge discreteness, and surface roughness on spherical electric double layers in electrolyte solutions with divalent counter-ions in the setting of the primitive model.

Tuning cell surface charge in E. coli with conjugated oligoelectrolytes. [PDF]

open access: yes, 2016
Cationic conjugated oligoelectrolytes (COEs) varying in length and structural features are compared with respect to their association with E. coli and their effect on cell surface charge as determined by zeta potential measurements.
