coupling phase

(redirected from cis phase)

cou·pling phase

the physical relationship of two syntenic genes. If they are on the same chromosome, they are said to be "in coupling" or "in the cis phase"; if on opposite members of a chromosome pair, "in repulsion" or "in the trans phase."

In this study, based on XRD data from Figure 3 at 10 h, pure CIS phase is observed with 0.5-1 micron spherical particles, worm-like, irregular shaped nanoparticles as shown in Figure 4(a).
At 20 h process, pure tetragonal CIS phase was observed.
[16] obtained pure CIS phase at 2000C for 15 hours.
In addition, the weight loss of path B was about 0.1% at 350[degrees]C and about 2.5% at 600[degrees]C, which indicated that the path B might require higher reaction temperature to form CIS phase. As a result, the path B for synthesizing CIS phase was relatively difficult at 350[degrees] C, while the solid state reaction kinetics of path A was presumably dominated by [In.sup.3+] ions diffusion [15].
