28] demonstrated that a large number of metastable needle-like precursors could be generated at high temperature (142[degrees]C) even above its equilibrium melting temperature ([T.
Metastable austenite in 17-4 precipitation-hardening stainless steel produced by selective laser melting.
Therefore, there is a need to establish the true nature of two-phase flow and the existence of metastable flow within the adiabatic capillary tube.
Correspondingly, the oil-water emulsions are considered as metastable, microheterogeneous systems consisting of two practically non intersoluble liquids (Daling, Strom 1999; Wei et al.
quantum states are metastable (neither perfectly stable, nor unstable);
While it's known that Hsp90 works on a particularly interesting group of client proteins comprising metastable signal transducers that are key regulators of a broad spectrum of biological processes, determinants of client recognition by HSP90 have remained frustratingly elusive.
Xenon-133m, a metastable isotope needed to pin down the fissile material type, has a half-life of just over two days.
He is best known for his work on metastability, starting with his pioneering work first published in 1972 that described the behaviour of synchronizer circuits in the MU-5 computers, and continuing through the design of numerous, novel synchronizer circuits, and developing laboratory technique for observing metastable circuit behaviours.
If sufficient quantities of the metastable tetragonal phase is present, then an applied stress, magnified by the stress concentration at a crack tip, can cause the tetragonal phase to convert to monoclinic, with the associated volume expansion.
For applied low-voltage electric fields in the nitrogen atmosphere, the effect of primary ionization is small compared with the associative collision ionization of metastable nitrogen molecules.
The aragonite is metastable and converts irreversibly to the calcite form when heated above 400[degree]C.
If hyperglobalization implies economic instability (or perhaps more precisely, a set of dynamics embodying a greater number of possible metastable suboptimal equilibria), and if no one wants to pull back from national democratic politics and sovereignty (except perhaps a few remnant idealists and proto-tycoons bent on monopolization), then it is hyperglobalization that must give way.
However, some special states may live much longer, up to several seconds or more before they decay, and are therefore called metastable states.
