Design Geometry Optimization of Vertical Cracks in Thermal Barrier Coatings from Simulated Thermal and Mechanical Behavior

C. Heveran[1], J. Xu[1], D. Cole[2], S. Basu[1], V. Sarin[1]
[1]Division of Materials Science and Engineering, Boston University, Brookline, MA, USA
[2]Department of Mechanical Engineering, Boston University, Brookline, MA, USA

Turbine blades are coated with thermal barrier coatings (TBCs) to reduce operating temperature. TBCs experience stress from coefficient of thermal expansion mismatch with the bond-coat and substrate. Vertical cracks are thought to offer stress relief, but influence of crack geometry on ... En savoir plus

Heat Transfer and Phase Transformation on Matrix Assisted Pulsed Laser Evaporation (MAPLE) of Biocompatible Thin Layers

E. Lacatus[1], G.C. Alecu[1], M.A. Sopronyi[2], A. Tudor[1]
[1]POLITEHNICA University of Bucharest, Bucharest, Romania
[2]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique is used for the deposition of high quality biocompatible polymer thin films. During the deposition process the temperature of the laser target should be kept below 193K to assure the proper quality of both evaporation and ... En savoir plus

Thermal Model for Single Discharge EDM Process Using COMSOL Multiphysics

K. Gajjar[1], U. Maradia[2], K. Wegener[2]
[1]Indian Institute of Technology Bombay, Mumbai, Maharshtra, India
[2]Institute for Process Tools and Manufacturing (IWF), Zurich, Switzerland

Electrical Discharge Machining (EDM) is a non-conventional process used for machining electrically conducting materials. In die sink-EDM, sparks are generated between tool and workpiece resulting in heating of both electrode surfaces and creating a melt pool of metal which leads to ... En savoir plus

Development of a Single Cell Trapping Microfluidic Device

L. Weng [1], F. Ellett [1], J. F. Edd [1], M. Toner [1,2],
[1] Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA
[2] Shriners Hospital for Children, Boston, MA, USA

Array-based technologies are important for many applications in drug discovery, microbiology and cell biology. A large-scale array of single cells allows high-throughput monitoring of behaviors of individual cells in parallel, avoiding the lack of cell specificity inherent to bulk ... En savoir plus

Enhancing Fluorescence of Diamond Color Centers near Gold Nanorods via Geometry Optimization
