This paper presents a successful step towards the development of a “web-based laboratory” for teaching basic, and even advanced, electromagnetic concepts. The main idea is to develop a reusable model for the student to be used exactly as a hardware experiment in a physical laboratory, ... Per saperne di più
Transient eddy current (TEC) technique is being developed for detection of flaws located at depth within multilayer aluminum structures. The present work involves finite element modeling using COMSOL Multiphysics software to simulate different types of probes by changing some of these ... Per saperne di più
Microwave drying of fruits and vegetables in a domestic oven has been found to result in large textural changes in the product such as puffing, crack formation and even burning due to the inhomogeneous heating of the microwaves. Microwave drying of potatoes is a complex interplay of ... Per saperne di più
基于纸基微流控芯片(μPAD)的核酸提取和扩增反应需均匀稳定、快速响应的热源。半导体制冷器具有无需制冷剂和体积小等优点，可为纸基芯片提供便携式、低功耗分析平台。相较于其他传统核酸扩增与检测设备，μPAD可以借助内部纤维结构的毛细作用自驱动输送流体介质。并且，微尺度下纤维结构具备较高的比表面积，在原理上可改善常规比色、荧光等检测方法的检出限和精准度。然而，滤纸材料本征参数对试剂溶液动态扩散过程和反应结果影响很大，数值仿真模拟是μPAD性能分析和优化设计的重要途径。本文应用COMSOL®热电效应耦合模块和非等温流动耦合模块，获取芯片内部的温度场信息，评价μPAD温控系统设计 ...
