Analysis of a Plasma-Mediated Photoacoustic Response From Plasmonic Nanoparticles in Ultrashort Regime
Over the last decade, plasmonic nanoparticles (PNPs) have received growing interest as exogenous contrast agents in the thermal expansion based photoacoustic (PA) imaging technique in biomedical applications [1]. Such functionality is due to the localized surface plasmon resonance (LSPR) ... Per saperne di più
Design and Analysis of a Three-DOF Piezoelectric Vibration Energy Harvester
Introduction: Vibration energy harvester can convert mechanical vibration energy into electrical energy and store it in battery for later use. It can create clean renewable energy from vibration movements such as walking, jumping, running, etc. This can convert energy previously wasted ... Per saperne di più
COMSOL Multiphysics® Software Activities Within the Research Reactors Division of Oak Ridge National Laboratory
INTRODUCTION Our group at ORNL started using COMSOL Multiphysics® software shortly after version 3.0 was released in the Spring of 2004. After 11 years and several releases, the application usage has grown along with number of licenses we are responsible for. This paper will broaden ... Per saperne di più
Thermal Stresses in Functionally Graded Metal-Ceramic Plates
Functionally graded composite materials are attracting interest among design engineers since structural component properties can be designed and customized into finished parts through processing.
