Characterization of the Interface Dipole at Organic/ …

2018-7-14 · In organics-based (opto)electronic devices, the interface dipoles formed at the organic/metal interfaces play a key role in determining the barrier for charge (hole or electron) injection between the metal electrodes and the active organic layers. The origin of this dipole is rationalized here from the results of a joint experimental and theoretical study based on the interaction between

POs‐Ca ® is a calcium salt of phosphoryl oligosaccharides (POs) obtained from potato starch. POs‐Ca ® is stable at the temperature and pH values encountered for its intended use in chewing gum, hard confectionary, sugar‐free soft candy and apple juice. POs‐Ca ® is highly soluble in water and readily dissociates into phosphorylated oligosaccharides and calcium in the gastrointestinal

In the co-crystals of metal-free ConA with Zn2+ (Zn-ConA), the zinc ion can fully occupy the S1 site. The positions of the carboxylate ligands Asp10 and Asp19 that bridge the S1 and S2 sites are affected. The ligation to Zn2+ orients Asp10 optimally for calcium ligation and stabilizes Asp19 by a hydrogen bond to one of its water ligands.

What type of bond does calcium and chlorine have? - …

Whenever calcium, or just about any metal for that matter, forms a bond with another element, be it a metal or non-metal, it will form an ionic bond; this is due in part to the low electronegativity of Calcium, as it will strip the other atom of its excess electron(s) rather than experience a mutual exchange of electrons.
