The search for energy saving is nowadays mandatory because of the constant growth of CO2 emissions caused by an inefficient energy management. Thermal Energy Storage (TES) has an important role in designing of energy efficient systems, including solar energy storage (daily or seasonal) ... Mehr lesen
The aim of the proposed device is to overcome the typical drawbacks of MHD generators, such as the needed of a very high external magnetic field, the strong dependency of the efficiency by the temperature of the fluid, and the deterioration of the electrodes that are in contact with the ...

电磁辐射对燃油危害是加油站、炼油厂、油气基地等大型设施禁用手机和其他无线通讯设备的重要原因。不同于静电对燃油蒸气的危害,本文的研究重点在于分析不同频率下的射频放电击穿特性。基于射频等离子体鞘层模型,通过多物理场仿真,分析了12M~300MHz频率下的氩气射频放电过程。仿真结果表明,当激励频率大于雪崩击穿临界频率时,两侧极板附近会形成随激励周期变化的鞘层区,中心区域为准电中性的等离子体区。同时,当激励频率远小于等离子体频率时,鞘层会促进极板附近的γ电离过程;随着频率增大,鞘层特性会逐渐退化,而中心区域的α电离过程会增强。此外,放电特性曲线表明,频率越高,板间放电电压越小 ...

A study of an atmospheric pressure direct current microplasma discharge in He/N2 is performed using COMSOL Multiphysics. The calculation of heat transfer is fully coupled with the plasma simulation so as to resolve the gas heating in discharges. A simple circuit model is used to decide ... Mehr lesen
The field of Biomedical Engineering is expanding at an exponential rate. As we began to unravel clues about our complex biological vessels, we uncovered more questions than answers. Our collective curiosity has led biomedical engineering into a broadening field by study of physiological ... Mehr lesen
Based on experimental data describing the Ca2+ dynamics over a time period of 5 s in non-stimulated T Cells obtained via high-resolution Ca2+ imaging, it was possible to identify the appearance of random spontaneous Ca2+ microdomains inside the Endoplasmic Reticulum (ER) - Plasma ... Mehr lesen
Corona discharge is used in several applications such as surface treatment of polymers, photocopying or dust removal in air conditioning. Streamer formation is undesirable for most of these applications. Therefore, several studies have been dedicated to investigate the formation and ... Mehr lesen
As interest in the electromagnetic spectrum expands towards the infrared and terahertz range, the distinct advantages of using semiconductors instead of metals for plasmonic applications must be understood. Plasmonic resonances in gold (Au) and indium nitride (InN) gratings are studied, ... Mehr lesen
Murphy and Good general theory for electron emission from metal surfaces was used to predict the field-emission capabilities of ideal arrays of vertically aligned carbon nanotubes (VACNT). The Nottingham effect was taken into account in order to explain experimental observation of a ... Mehr lesen
The main purpose of SPIDER (Source for the Production of Ions of Deuterium Extracted from RF plasma) test facility is the investigation and optimization of a negative ion beam produced by the full size ion source for ITER NBIs (Neutral Beam Injectors). Thermal, transient, non-linear FE ... Mehr lesen
