This results in bond polarity and ionic character as the more electronegative atom will have a partial negative charge and the neighboring atom will have a partial positive charge. The larger the difference in electronegativity between two atoms in a bond, the more p...

Consequently, there is considerable ionic polarization due to the displacement of the core Pb2+ cations and Br− anions. The structural, electrical, and optical guidings of CsGeI3 perovskite are significantly affected by compressive and tensile strain. For instance, when the strain is adjusted ...
The binding of AuF-gold atom to Sx1A was used to probe a covalent disulfide linkage of AuF with Sx1A C271 and C272. Towards that end a recombinant His-tagged RFP-Sx1AC145A mutant was expressed in Xenopus oocytes (Fig. 7a). Oocytes were treated with or without 5 mM AuF for 30 min,...
Color rendition, luminous efficacy and reliability are three key technical parameters for white light-emitting diodes (wLEDs) that are dominantly determined by down-conversion phosphors. However, there is usually an inevitable trade-off between color ren
concentrations, the micelles rather effectively protect Pt1 from interactions with proteins; however, at extremely high protein concen- trations, it seems that BSA can compete with micelles for binding with Pt1 and solubilize part of this complex by the formation of non-covalent adducts [37–39]...
(1) its electrical properties that combine ionic and electronic dual conduction, (2) its processability enabling compliant mechanical properties, and (3) its high volumetric capacitance well suited for electrophysiological recording and stimulation. These features ...
Since Lambda for an oxide is proportional to the degree of negative charge borne by the oxide-(-II) atom or ion, it follows that optical basicity should go hand-in-hand with the ionic/covalent nature of the cation-oxide-(-II) bonding. Unfortunately, this assumption produces many anomalies ...
