Gangbo and McCann showed that optimal transportation between hypersurfaces generally leads to multivalued optimal maps – bivalent when the target surface is strictly convex. In this paper we quantify Hölder continuity of the bivalent map optimizing average distance squared between arbitrary measures supported on Euclidean spheres.

This paper describes the development of a new bivalent system comprising synthetic dimers of carbonic anhydrase linked chemically through thiol groups of cysteine residues introduced by site-directed mutagenesis. These compounds serve as models with which to study the interaction of bivalent proteins with ligands presented at the surface of mixed self-assembled monolayers (SAMs). Monovalent car...

Exploring noble metal-free catalyst materials for high efficient electrochemical water splitting to produce hydrogen is strongly desired renewable energy development. In this article, a novel bifunctional catalytic electrode of insitu-grown type alkaline based on FeCoNi alloy substrate has been successfully prepared via facile one-step hydrothermal oxidation route in an peroxide medium. It show...

ABSTRACT. Adrenaline complexes with bivalent ions Mg2+, Ca2+, Sr2+ and Ba2+ in methanol at 60 oC were prepared. The prepared isolated characterized using elemental analyses, conductivity measurements, mid infrared, Raman laser, UV-Vis., 1H–NMR spectra, X-ray powder diffraction, scanning electron microscopy energy-dispersive spectroscopy (EDX). Upon the spectroscopic, stoichiometric reactions in...

In the current research, polyvinylchloride based mixed matrix heterogeneous anion exchange membranes were prepared by a solution casting technique. Titanium dioxide nanoparticles were also utilized as inorganic filler additive in the membrane fabrication. The effect of TiO2 nanoparticles concentration in the casting solution on the membrane physico-chemical properties was studied. Membrane wate...
