Nucleation time lag at nano-sizes
A rapidly convergent exact expression for the time lag (also, induction time ) of transient nucleation obtained by Shneidman and Weinberg [J. Chem. Phys. 97 (1992) 3629] is used to evaluate the lag for clusters with up to 10 monomers. Asymptotic approximations to the exact expression are further advanced to provide explicit elementary expressions for the time lag in the Turnbull–Fisher (TF) nuc...
متن کاملIn¯uence of the Nucleation Time-lag on the Activation Energy in Non-isothermal Crystallization
In the present work, the in¯uence of the nucleation time-lag on the non-isothermal glass crystallization is discussed. Dierential thermal analysis (DTA) results of an iron-rich glass nucleated by Cr 2 O 3 were obtained at dierent heating rates. The activation energy of crystallization, E c , and the Avrami parameter, m, estimated by Kissinger's and Ozawa's equations were shown to be dependent...
متن کاملAsymptotic relations between time-lag and higher moments of transient nucleation flux
Exact relations between Tk , the kth temporal moments of the nucleation flux, and the derivative of its Laplace transform ~LT! are established and applied to available asymptotic expressions for the LT, generalizing earlier results by Shneidman and Weinberg @J. Chem. Phys. 95, 9148 ~1991!; 97, 3629 ~1992!# on the time-lag T0 . For any k>2 the moments Tk are expressed through simple algebraic co...
متن کاملA Guide to Time Lag and Time Lag Shortening Strategies in Oncology-Based Drug Development.
One of the ongoing challenges for academic, biotech and pharma organizations involved in oncology-related research and development is how to help scientists be more effective in transforming new scientific ideas into products that improve patients' lives. Decreasing the time required between bench work and translational study would allow potential benefits of innovation to reach patients more q...
متن کاملLag Patterns in Time Series Databases
Time series motif discovery is important as the discovered motifs generally form the primitives for many data mining tasks. In this work, we examine the problem of discovering groups of motifs from different time series that exhibit some lag relationships. We define a new class of pattern called lagPatterns that captures the invariant ordering among motifs. lagPatterns characterize localized as...
