(n.) The legalized use of two metals (as gold and silver) in the currency of a country, at a fixed relative value; -- in opposition to monometallism.
Example Sentences:
(1) As well as a “bimetallic” construction similar to the existing £2 coin, the new £1 will feature new banknote-strength security pioneered at the Royal Mint’s headquarters in Llantrisant, South Wales.
(2) This is associated with reversed electron transfer from the bimetallic center to ferricytochrome c. The kinetics of reduction of ferricytochrome c by the reversed electron transfer process are compared with the kinetics of formation of F and P. The results are consistent with transfer of one electron from the ferric-cupric bimetallic center (O) to cytochrome c, yielding the F intermediate, followed by transfer of one electron from the latter to cytochrome c, yielding the P state.
(3) The main current-generating corrosion cells in the oral cavity are the bimetallic cell and the concentration cell, the latter mainly occurring due to differences in access to oxygen in the various parts of the metallic material.
(4) Thirty referred patients and 15 control subjects were investigated with reference to the occurrence of bimetallic corrosion in the oral cavity.
(5) In contrast S2- or SH- is unable to form any bridge and it seems likely that two SH- ions are bound by the bimetallic site, one to Fe III a3 and the other to CuB I.
(6) The results show that only two of the electron transfers, to the 'peroxy' and 'oxyferryl' intermediates of the bimetallic centre, are linked to proton translocation, a finding which strongly constrains candidate mechanisms for proton-pumping.
(7) The bimetallic electrical implant did not produce regenerative healing under the conditions of this experiment.
(8) Its bimetallic construction is similar to the existing £2 coin.
(9) Here, I report the effects of proton-motive force and membrane potential on two equilibria involving intermediates of the bimetallic centre at different levels of O2 reduction.
(10) The compound is a bimetallic fulvalene complex with rhodium and tungsten oriented trans to each other across an essentially planar fulvalene dianion.
(11) As to the proteins whose redox potential is not facilitative and appreciably higher than -0.33 V, a bimetallic, concerted, two-equivalent reduction of the bound dioxygen to the peroxide level would be much more favoured without the intermediate formation of O2-.
(12) Analysis suggests that the two rapid reaction phases represent internal electron redistributions between the bimetallic site and cytochrome a, and between cytochrome a and CuA, respectively.
(13) At a high redox potential (Eh) of cytochrome c, high pH, and a high electrochemical proton gradient (delta mu H+) across the inner mitochondrial membrane, the initial ferriccupric state (O) of the oxidized enzyme's bimetallic oxygen reaction center is converted to ferryl (F) and peroxy (P) intermediates, the optical spectroscopic properties of which are reported in detail.
(14) In this evolution of special importance were bimetallic enzymes, such as nitrogenase, some nitrate reductases and hydrogenases, carbon dioxide reductase, xanthine oxidase, cytochrome oxidase.
(15) During respiration, an exogenous donor, cytochrome c, donates four electrons to O2 bound at the bimetallic haem alpha 3 Fe-Cu centre within the enzyme.
(16) The effect of different sodium chloride concentrations on the integrated currents (charge transfers) between dental amalgams and a gold alloy was studied in a bimetallic cell containing saliva or saline solutions.
(17) This is considerably slower than the maximal rates observed for electron transfer between cytochrome a and the bimetallic site found in earlier work and suggests rate limitation by other processes.
(18) The bimetallic haem iron-copper reaction centre in this family of enzymes is the critical structure for catalysis of both these processes.
(19) The bimetallic super-coiling might contribute to the power-stroke.
(20) Interestingly, in these circumstances (azide and uncoupler present), Fea behaves as if it were no longer the kinetically controlling electron donor to the bimetallic center.
