Deoxidation of Graphene using Caffeic Acid

The graphene which is a two dimensional carbon structure has been significantly explored due to its excellent mechanical and physical properties. Based on its prominent properties, graphene has a wide range of useful applications. Among the methods for synthesizing graphene, chemical method is known as the most powerful method for mass production of graphene. During the process, to achieve high...

Alumina Inclusion Behavior during Steel Deoxidation

A computational model based on classic homogenous nucleation theory, thermodynamic analysis and numerical simulation, has been developed to study steel deoxidation by aluminum in a low carbon aluminum-killed steel ladle, which calculates the nucleation and time evolution of the alumina inclusion size distribution due to Ostwald ripening, Brownian collision and turbulent collision. Starting with...

Local Synchronization with Batching

We examine the reduction in efficiency in a system where each processor has a sequence of tasks and must synchronize with other processors after each task is done. This occurs, for example, in many stepwise simulations. In OpenMP, the only explicit synchronization is the barrier, which causes all processors to wait for the slowest one. This is problematic when the tasks take variable amounts of...
