Elastocaloric effect in Cu - Zn

This work aims to study the elastocaloric effect in a Cu-Al-Zn shape memory alloy sample. The elastocaloric effect refers to the reversible thermal response (isothermal entropy change, or adiabatic temperature change) of a body when subjected to a uniaxial stress. To measure the entropy change of the martensitic transformation, differential scanning calorimetry technique has been used. The calo...

Prokaryotic Cu,Zn superoxide dismutases.

The Cu,ZnSODs (Cu,Zn superoxide dismutases) comprise a class of ubiquitous metalloenzymes that catalyse the dismutation of the superoxide radical anion into oxygen and hydrogen peroxide. The dismutation reaction involves two successive encounters of the superoxide anion with a catalytic copper centre hosted by the enzyme at the dead end of a narrow protein channel. Cu,ZnSOD is found in all euka...

ANELASTIC EFFECTS IN SINGLE CRYSTALS OF -Cu-Zn AND -Cu-Zn-Al ALLOYS

Characterization of calf liver Cu,Zn-metallothionein: naturally variable Cu and Zn stoichiometries.

Cu,Zn-metallothioneins were purified from bovine calf liver in order to examine the stoichiometry of metal binding to the protein. Copper and zinc analyses were carried out by atomic absorption spectrophotometry. Consistent quantitative thiolate analyses were obtained spectrophotometrically with Ellman's reagent and amperometrically with phenylmercuric acetate. These were used to define protein...
