Insulator oxide film formation with acid catalyzed hydrolysis of alkoxides in supercritical fluid carbon dioxide

Wang J-S., Wai C.M., Brown G.J., Apt S.D., Campo A.M., Landis G.R., Air Force Research Laboratory, US

Insulator oxide films can be produced by hydrolysis of metal alkoxide precursors in the presence of an acid catalyst in supercritical fluid carbon dioxide(sc-CO2). In this study, a new process has been developed to cover [...]

Nanoparticles: Synthesis and Film Deposition Using a Simple and Fast Centrifuge Sedimentation Method

Wang J-S., Markelonis A.R., Wai C.M., Brown G.J., Air Force Research Laboratory, US

Gold nanoparticles were prepared by reduction of gold cations suspended in sodium bis(2-ethylhexyl)sulfosuccinate (AOT) water-in-hexane microemulsions with another AOT microemulsion containing a reducing agent NaCNBH3. The size of the Au nanoparticles can be controlled by [...]

Improved O(N) Neighbor List Method Using Domain Decomposition and Data Sorting

Yao Z-H, Wang J-S., Cheng M., National University of Singapore, SG

The conventional Verlet table neighbor list algorithm is improved to reduce the number of unnecessary interatomic distance calculation in molecular simulations involving many atoms. Both of the serial and parallelized performance of molecular dynamics simulation [...]

Hybrid P-Element and Trefftz Method for Capacitance Computation

Gyimesi M., Wang J-S., Ostergaard D.F., ANSYS, Inc., US

The paper discusses efficient electrostatic field solutions techniques to simulate micro electro mechanical systems (MEMS): adaptive p-elements to remove the burden of manual mesh refinement; hybrid finite elements - Trefftz formulation to treat open boundary [...]
