The aim of the present study was to determine the effect of the electrostatic charge of lipoproteins on the phospholipid transfer activity of the plasma phospholipid transfer protein (PLTP). Progressive decreases in the PLTP-mediated phospholipid transfer rates were observed when the surface potential of isolated high density lipoproteins (HDL) was either reduced from -11.7 mV down to -15.7 mV ...

We are introducing an alternative analytical expression to the electronegativity difference (∆χ) as a function of charge ge, g is factor, fraction electronic devoted bond and e elementary charge, packing factor (p) effective atomic number (Zeff) binary ionic solids, by using very basic Coulomb interaction, modified introduction p, relationship between electric dipole moment (µ) ∆χ in Debye unit...

Abstract Abstracted from real compounds, chemical elements can be considered a system tied by bonds (or bonding relationships) between two elements, namely the element and bond system. Then, their properties studied view of complex networks. Based on previous work, we introduce polarity to judge edge direction select four electronegativity scales build directed Taking node importance as an exam...

In addition, they do not need to be poled because they directly crystallize from melt or solution into the ferroelectric (β-) phase. Piezoelectricity in these materials is related to the electronegativity difference in hydrogen and fl uorine atoms, which determines an effective dipole moment in the direction normal to the carbon backbone. Consequently, these fi lms or nanostructures are often u...

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are a class of fluorinated organic chemicals containing at least one fully fluorinated carbon atom. The C-F bond is one of the strongest known covalent bonds, and the multiple C-F bonds in PFASs impart their chemical and thermal stability. The strength of the C-F bond arises, in part, from the electronegativity of the fluorine atom and from ...
