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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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. Synthetic nanofluidic architectures that mimic the gating functions of biological ion ... Per saperne di più
Binder jet printing (BJP) is one of the additive manufacturing methods that are being widely implemented as an efficient alternative for casting and machining in the automotive industry. Sintering densification of the as-printed part (green part) adds uncertainty and possible undesirable ... Per saperne di più
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, ...

Photofrin-mediated photodynamic therapy (PDT) is used after surgical resection at the University of Pennsylvania to treat the microscopic disease for malignant pleural mesothelioma and to increase survival rate. When Photofrin is exposed to laser light at 630 nm in well-oxygenated ... Per saperne di più
Increased demand for high power electronics has required increasingly more efficient thermal management techniques. Simple cold plates using tubes or channels are frequently used to cool high power components but restrictions on size, weight, and power have restricted their ... Per saperne di più
Laser direct deposition is a process, different from molding or machining, which allows the producing of fully densified and operational components. This technique involves injecting metal powder through a coaxial nozzle into a melt pool obtained by a moving laser beam. The final object ... Per saperne di più
In this work we tackle a more theoretical aspect of micro-injection molding, to better understand physics during the process, through numerical simulations of cavity filling. We developed a two phase flow approach by the use of COMSOL Multiphysics®. In a first step, a Level Set model is ... Per saperne di più
