The nature and kinetics of the equilibrium processes at interface between copper electrode alkaline solution containing glycine complexes Cu(II) have been studied. material balance equations that consider formation Сu(I) were used to calculate composition system. It was found amount compounds increases with increasing pH ligand concentration. Using EQCM method it electrochemical dissolution Cu ...

This publication describes the straightforward and redox-neutral synthesis of 10-bromophenylethynylcobalamin its facile conversion to 10-bromoaquacobalamin. In this approach, phenylethynyl ligand acts as convenient light-stable protecting group that is removed in quantitative yield under acidic conditions. The proteolytic cleavage at pH 2.0 was studied pseudo-first-order conditions 1.5 times sl...

A fully differential Miller op-amp with a composite input stage using resistive local common-mode feedback and regulated cascode transistors is presented here. High gain pseudo-differential auxiliary amplifiers are used to implement the in order boost output impedance of open-loop op-amp. Both stages operate class AB mode. The proposed has been simulated 130nm commercial CMOS process technology...

presence of distributed generation (dg) in electric distribution systems provides an attractive new alternative in capacity expansion planning of these systems. in this paper a new model is developed for solving simultaneous placement of hv/mv substations and dg units as a static planning tool. this model aims to minimize fixed and variable costs of planning. constraints related to dgs, substat...

Protonated heterocyclic amines, such as pyridinium, have been utilized as catalysts in the electrocatalytic reduction of carbon dioxide. While these represent a new and exciting class of electrocatalysts, the details of the mechanism and faradaic processes occurring in solution are unclear. We report a series of cyclic voltammetry experiments involving Pt, Ag, Au, and Cu electrodes, under both ...

The classical Cantor–Bernstein theorem says that two sets X;Y which admit injective mappings X ! Y and Y ! X have the same cardinality. We obtain a di¤erent problem when the sets are equipped with an additional structure which should be preserved by the mappings (isomorphisms). It has been generalized to boolean algebras by Sikorski and Tarski: For any two -complete boolean algebras A and B and...

By considering the notion of MV-algebras, we recall some results on enumeration of MV-algebras and wecarry out a study on characterization of MV-algebras of orders $2$, $3$, $4$, $5$, $6$ and $7$. We obtain that there is one non-isomorphic MV-algebra of orders $2$, $3$, $5$ and $7$ and two non-isomorphic MV-algebras of orders $4$ and $6$.
