Photonic/Plasmonic Structures from Metallic Nanoparticles in a Glass Matrix

O. Kiriyenko, W. Hergert, S. Wackerow, M. Beleites, and H. Graener
Inst. für Physik, Martin-Luther-Universität Halle-Wittenberg, Germany

Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying ... Read More

Analysis of Coupled Dynamics of Molten Salt Reactors

V. Di Marcello, A. Cammi, and L. Luzzi
Department of Energy, Nuclear Engineering Division (CeSNEF), Politecnico di Milano, Milano, Italy

This paper presents a preliminary analysis of the coupled thermo-hydrodynamics and neutronics of circulating nuclear fuel systems in a nuclear reactor that adopts a molten salt mixture. This flows up through channels in a graphite moderated core and plays the role of both heat generator ... Read More

Computation of Three-Dimensional Electromagnetic Fields for an Augmented Reality Environment

A. Buchau, and W. Rucker
Institut für Theorie der Elektrotechnik, Universität Stuttgart, Germany

Augmented reality is predestined for visualization of electromagnetic fields in air or inside transparent matter. Real existing objects are studied and invisible electromagnetic fields are added as virtual objects. Hence, experts as well as students are able to connect electromagnetic ... Read More

Modeling the Behavior of Single Particle during Drying Process

S. Bellur, B. Agasanpura, and C. Coronella
Chemical and Metallurgical Engineering Department, University of Nevada, Reno, Nevada, USA

The aim of the present work is the formulation of a computational model describing transport phenomena in transient biosolids drying. COMSOL Multiphysics was used to perform the simulations, with two spatial dimensions. After a time step of 0.1 s, we found that the solid reached thermal ... Read More

Parameter Optimization for Finite-Element Method (FEM) based modeling of singlet oxygen during PDT

T. Zhu, and K. Wang
Department of Radiation Oncology, School of Medicine, University of Pennsylvania, Philadelphia, PA, USA

Photodynamic therapy(PDT) is a new cancer treatment modality using the photochemical reaction of a photosensitizing drug, light, and oxygen. The objective of this project is to determine the photochemical parameters necessary for singlet oxygen modeling during PDT using parameters ... Read More

FEM Analysis of Contaminant Transport in a Loamy Desert Soil

B. Agasanapura, C. Nesbitt, and M. Misra
Chemical and Metallurgical Engineering, University of Nevada, Reno, Nevada, USA

In the present work, transport and adsorption of contaminants (lead, cesium) on loamy desert soil was modeled using the Finite Element Method (FEM). The Advective dispersion reaction mechanism was employed to describe the contaminant transport in soil medium. A partial differential ... Read More

Investigating the Use of a Piezoelectric Actuator for the Appendages of a Microrobot

J. Clark, and J. Clark
Purdue University, West Lafayette, IN, USA

We investigate the use of a piezoelectric actuator for the appendages of a microrobot. Possible uses may include micro assembly, mobile surveillance, etc. What is different about this microrobot is that it uses 2 degrees of freedom, low powered piezoelectric flexures, while attempting to ...
