Additive manufacturing uses 3D printing to build physical parts from CAD-based designs. The technology includes fused deposition modeling (FDM) and selective laser sintering (SLS) methods. 3-D printing is of particular interest for smaller, one-of-a-kind, customizable products. A cube ... Per saperne di più
Cu-Nb multilayer nanocomposite has prospective applications in nuclear industry because of its ability to self-heal from radiation damage. The goal of the study is to find a suitable joining method for the composite to produce industrial-scale pieces, free of defects threatening the ... Per saperne di più
光中包含着巨大的能量，光能的利用一直是研究的热点。基于半导体纳米颗粒的吸光特性（如二氧化钛、氧化锌、四氧化三铁等），我们首先通过实验研究了在光强具有高斯分布的激发光作用下，微液滴内悬浮纳米颗粒的受迫运动，发现在液滴内产生了~mm/s的对称涡流，表明这一方法是在粘性主导的微流动下形成高速流动的有效手段。机理分析表明，这一光与液滴相互作用问题的物理机制为非均匀光热效应(温度梯度~1000K/m)及其所诱导的Marangoni对流，是一个包含光、热、物质与流体双向作用、界面张力梯度的复杂多物理场耦合流动问题。为了模拟这一实验现象，我们在COMSOL ... Per saperne di più
Hydrophones are acoustic receivers, which can be used to listen to the sound propagating underwater for the purposes of monitoring marine life, or other sound producing activities in the sea. Commonly used hydrophones are based on piezoelectric transducers. With the introduction of fiber ... Per saperne di più
A program for self-consistent modeling of electron-hole energy spectrum and space-charge distribution in III-nitride based quantum well (QW) structures has been developed. The model takes into consideration full 6-band description of the valence band states, nonparabolicity of the ... Per saperne di più
The topic of my work is modeling of a multimodal waveguide microprobe which is suitable for deep brain infrared stimulation. The goal of the research is the investigation of the therapeutic effect of optical IR excitation on biological active substances. In the physical model I ... Per saperne di più
Outline of presentation: We have seen a few of the diverse ways e2v has started to use COMSOL It is allowing us to view our processes in a different way Resulting in improvements It is enabling our engineers and scientists to examine the full application, not just the microwave or RF ...

Marangoni flow affects the heat and mass transfer occurring in the molten metal regions in welding and additive manufacturing processes. It originates from the surface tension gradient (∂γ/∂T) induced at the melt pool surface due to the temperature difference. The flow pattern within ... Per saperne di più
The radio-frequency(RF) plasma sources have shown great potential in various industrial applications such as thin coatings deposition and polymers modification[1,2]. Physics of low pressure RF plasmas has been investigated significantly[3]; however, this kind of plasma source is rarely ... Per saperne di più
Over time, rechargeable batteries degrade and eventually stop working. You see some combination of declining capacity, rapid self-discharge, and reduced power. Degradation mode depends on battery design, but also on the application. Often, multiple physical processes contribute to ... Per saperne di più
