FE Simulation of material removal and surface properties for EDM during single and multiple spark occurrences

Lim H.J., Domblesky J.P., Kim N., Hwang S.Y., Sogang University, KR

EDM represents an effective machining process for hard-to-machine materials. Although EDM has many advantages, it lacks well-developed technological base and level of fundamental understanding that characterizes other metal cutting technologies. This has limited the development [...]

Surface properties of amorphous nanoporous GeS2

Ori G., Celino M-, Massobrio C., Coasne B., UMI CNRS / Massachusetts Institute of Technology, US

Amorphous nanoporous chalcogenides (chalcogels) represent a novel class of materials with promising properties for applications as catalysts, gas separation, and heavy metal environmental remediation. In the present work, first-principles molecular dynamics (FPMD) simulations are first [...]

Structural and Electronic Properties of Quantum Dot Surfaces

Galli G., Puzder A., Willilamson A.J., Grossman J.C., Pizzagalli L., Lawrence Livermore National Laboratory, US

We report on recent progress in studying the structural, electronic and optical properties of Si and Ge quantum dots, using first principles calculations. We used both ab initio molecular dynamics techniques and quantum Monte Carlo [...]
