Microcontact printing is a method for depositing patterns of thin films or molecular monolayers on surfaces using a polydimethylsiloxane (PDMS) stamp for selective mechanical contact (Figure 1). Undesired deformation of the stamp features during printing affects printed pattern quality. ... Per saperne di più
In our study of chaotic mixing, 3D velocity measurements (u,v,w) are required for evaluation of a micro mixer using a mix-prediction algorithm. The hybrid approach presented here combines 2D measurements, an imperfect numerical model, and appropriate fitting parameters. Because our ... Per saperne di più
AC electrothermal (ACET) micropumps are based on the temperature gradient caused by Joule heating or an external heat source in the bulk of an electrolyte. In this paper, a 2D simulation was performed to study the effect of substrate thickness and material (glass and silicon) for an ACET ... Per saperne di più
Flow focusing microchannels are widely used in droplet generation mechanisms. In this paper, the effect of linear vibration on the flow pattern in a flow focusing structure and the corresponding formed droplets were numerically investigated using COMSOL Multiphysics® software. The ... Per saperne di più
Different facilities for hadrontherapy have been built in the recent past. AISHa ion source has been designed by keeping in mind the typical requirements of hospital-based facilities, where the minimization of the mean time between failures (MTBF) is a key point together with the ...

In this paper, the mechanism of charging process was simulated and analyzed. The simulation was conducted using COMSOL Multiphysics® software, based on the laminar two-phase flow level-set interface coupling with the electrostatic interface. Meanwhile, different parameters (such as the ... Per saperne di più
This study presents a novel microfluidic chip integrated with biosensors and capillary microfluidics, specifically designed for target screening and precise fluid control. The capillary pumps facilitate spontaneous fluid delivery to the sensors, eliminating the necessity for external ... Per saperne di più
（1）研究内容及难点：电极腐蚀是电润湿器件主要失效模式。鉴于电润湿核心功能层（疏水绝缘层）多为多孔结构的现实，电场作用下导电流体在孔径中的传输行为对理解电极失效机理有重要意义。本文拟通过引入电渗流、电毛细耦合作用，揭示疏水绝缘层中复杂交错的孔洞内部流体运动规律，预测穿透孔径形成腐蚀通路的阈值条件。该研究的难点主要是需要考虑纳米孔洞中存在的空气域，需要计算纳米孔洞中电渗流如何挤压空气域到达绝缘层底部的电极表面。 （2）COMSOL Multiphysics仿真：仿真运用两相流和静电场，由于疏水绝缘层材料接触水后，会产生负的表面电荷，以及在电场的作用下，由Young ...
