Fundamental studies of atomic diffusion by computer simulation of atomic processes on the giga event scale and multiple PC's in parallel

Creator:

Zhang, Qiongshan

Abstract:

The classic treatment of diffusion by Einstein and by Chandrasekhar assumed conservative boundary conditions; mobile species were neither created nor destroyed on the sample surface. It is normal to assume that vacancies and host interstitials are created and annihilated on incoherent interfaces or free surfaces; i.e., these are assumed to...

An examination of point defects and atomic diffusion in silicon

Creator:

Monson, Tyrus K.

Abstract:

The self-interstitial defect is commonly regarded as important in regulating diffusion in silicon. A review of the literature reveals that the scientific bases for invoking the self-interstitial defect are weak, while an alternate defect, the vacancy cluster, has been largely ignored. One argument which has been used to establish dominance...

Improvement of cryopreservation regrowth of in vitro Ribes by pretreatment

Creator:

Luo, Jie, 1968-

Abstract:

Improved recovery of cryopreserved meristems and calli from in vitro currant (Ribes aureum Pursh and R. ciliatum Humb. & Bonpl.) plants was obtained by two-hour pretreatment with sucrose, proline, abscisic acid-responsive protein (RABP), and bovine serum albumin (BSA) solutions. Meristems and calli cold-acclimatized for one week were immersed in pretreatment...
