Continuum Theory of Polymer Crystallization

Arindam Kundagrami, M. Muthukumar

We present a kinetic model of crystal growth of polymers of finite molecular weight. Experiments help to classify polymer crystallization broadly into two kinetic regimes. One is o…

The X-ray Properties of Early-Type Galaxies in the Extended Chandra Deep Field-South

B. D. Lehmer, W. N. Brandt, D. M. Alexander +8

We investigate the evolution over the last 6.3 Gyr of cosmic time (i.e., since z ~ 0.7) of the average X-ray properties of early-type galaxies within the Extended Chandra Deep Fiel…
