The next step in the evolution of the metal sector of Additive Manufacturing and especially for Laser based Powder Bed Fusion is the production of multi-material components as shown by [1]. Therefore, the powder application module must be able to selectively arrange different powders in ... En savoir plus

Optical-Thermal-Mechanical analysis for Heat Assisted Magnetic Recording(HAMR)

Yueqiang Hu(胡跃强) [1], Yonggang Meng (孟永钢) [1], Lichun Shi (史李春) [1],
[1] State Key Labrotary of Tribology, Tsinghua University

The demand of the data storage continues increasing with the development of the big data, cloud computing technologies. Heat-assisted magnetic recording (HAMR) technology is the most promising technology for data storage to push the areal density up to 10 Tb/in2. In HAMR, the laser ... En savoir plus

Thermal Corrective Devices for Advanced Gravitational Wave Interferometers

M. Kasprzack [1], J. Ramette [2],
[1] Louisiana State University, Baton Rouge, LA, USA
[2] Hillsdale College, Hillsdale, MI, USA

The advanced gravitational wave detectors require injecting a high continuous power laser into the optical cavities of the interferometers to reach their design sensitivity. To mitigate the thermal aberrations created by absorption of this high power load into the various optical ... En savoir plus

Thermal-Optical Modeling of a Signal Enhancement Approach for Paper-Based Diagnostics

D. Gasperino [1]
[1] Intellectual Ventures Laboratory, Bellevue, WA, USA

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding ... En savoir plus

Thermal Analysis of Additive Manufacturing

S. Yushanov[1], J. S. Crompton[1], K. C. Koppenhoefer[1]
[1]AltaSim Technologies, LLC., Columbus, OH, USA

This study analyzed the laser powder bed additive manufacturing process. The laser is modeled as a moving heat source with time dependent heat transfer causing local, transient melting of the metal powder. Heat transfer is considered to take place due to convection in the molten metal ... En savoir plus

Optimization of Thermal Properties Identification of Complex Thin Films Using MATLAB® and COMSOL Multiphysics

N. Semmar[1], B. Wane[1]
[1]GREMI, UMR7344, CNRS-University of Orleans, Orléans Cedex 2, France

The importance of laser processing and thermal properties investigation of bulk materials and thin layers is still increasing. For thermal properties investigation many experimental systems were developed based on the photothermal effect. One of typical ways is to induce a rapid surface ... En savoir plus

Elucidating the Mechanisms of Charge and Temperature Modulated Ionic Transport in Nanochannels

G. Zhang [1], Y. Zhao [1],
[1] Department of Biomedical Engineering, University of Kentucky, Lexington, KY, USA

The transport of fluid through nanochannels is of importance in a variety of technological applications, including biological sensing, energy storage and conversion, chemical separation and many others.

Instituto de Microelectrónica de Madri
IMM-CNM (CSIC)
Madrid, Spain

The detection back-action phenomenon has received little attention in physical, chemical, and biological sensors based on nanomechanical systems. We show that this effect is very significant in ultrathin bimetallic cantilevers, in which the laser beam that probes the picometer scale ... En savoir plus

Lithium Niobate SAW devices for Multi-parameter Sensing : Modeling and Simulation Studies Using COMSOL Multiphysics®

R. Srivastava[1], S. Kale[1]
[1]Defence Institute Of Advanced Technology, India

Surface Acoustic Wave devices are classic examples of Micro Electro Mechanical Systems (MEMS). These devices basically utilize inter-digitated electrodes (IDE) and a piezoelectric layer deposited over a substrate. The input IDT is supplied with alternating voltage and because of this, ...
