The structural state of the material changes as a result of annealing.
In the case of occurrence of the phase transformations in thin ribbons of metastable alloys, the inhomogeneity of their structural state can cause substantial changes in characteristics of the transformations.
There is no evidence from the elasticity measurements of a structural transition at ∼430 K, so the onset of ionic conductivity is not obviously related to some specific change in structural state.
This paper discusses (i) the structure of the surface vanadia species in fresh and dehydrated catalysts, (ii) the structural and oxidation state changes during C4 hydrocarbon oxidation, and (iii) the roles of the oxide support, the surface oxygen species, and the acidity of the supported vanadia catalysts in selective oxidation catalysis.
Patterns of phase transitions across the phase diagram, the spontaneous strains that accompany changes in structural state, anomalies in the elastic and anelastic properties of BCFO 36, and correlations between elastic behavior and dielectric behavior are all revealing of the nature and strength of coupling between the multiple order parameters that operate in BFO CFO.
During TEM observation, we did not detect any change in the structural state of the rims.
Changes in the structural state of forests of the semi-arid U.S.A., such as an increase in tree density, are widely believed to be leading to an ecological crisis, but accurate methods of quantifying forest density and configuration are lacking at landscape scales.
However, what cannot be deduced from the rigor-like structural state are details of the conformational changes that initiate the power stroke and that accompany the transition from an initial weakly bound acto-myosin-ADP.Pi state to the actin-myosin rigor complex.
It is based on the concept originally developed in our laboratory for the design of structure-switching signaling aptamers that change structural states from a DNA DNA duplex to a DNA target complex upon target binding.
Structural changes due to VP16 were similar to those that were induced by RNAPII binding, suggesting that the structural state could control Mediator's biological activity.
These results exclude some of the most obvious causes for the observed low enzyme storage stability in 1,4-dioxane, mainly structural, dynamics and ionization state changes.
