Small nuclear ribonucleoprotein particles (snRNPs) are essential supramolecular complexes involved in pre-mRNA splicing, the process of post-transcriptional RNA modifications. The particles undergo complex assembly steps inside the cell nucleus in a highly dynamic compartment called the ... En savoir plus
本文介绍利用COMSOL传热模块对激光闪射法(Laser Flash Method)测量具有环形结构的碳化硅复合包壳的瞬态传热过程,进而获得对标准激光闪射法估算热扩散率/热导率的几何修正系数和温度修正系数。 碳化硅复合包壳由多层的单质SiC陶瓷基体、SiC纤维编织层组成。碳化硅复合包壳在高温蒸汽中抗氧化性远远优于锆合金,因此被视为未来核电站燃料棒包壳的理想解决方案。为了开展碳化硅复合包壳的性能分析,需要使用激光闪射法获得其在500K~1800K温度范围的热扩散率。问题在于,激光闪射法标准(ASTM E1461-13)规定的样品形状为薄圆片 ... En savoir plus
Optical wave interference can perform instantaneous operations, such as: addition, subtraction, multiplication, and more complex operations like Fourier transform [1]. Being able to develop an optical computer that directly executes these operations without the need for a digital ... En savoir plus
Modeling the effects of electromagnetic fields on biological structures on the order of the body and tissues to the micro (1e-6)-and nano (1e-9) level of cells and sub-cellular structures presents formidable challenges. We share the major lessons we have learned using COMSOL ... En savoir plus
The measurement and regulation of particulate matter to improve outside air quality advanced a lot over the last decades. This also made it necessary to develop primary standards for calibrating these measurement systems and in future the composition of relevant aerosols will be taken ... En savoir plus
Accurate bipolar-plate and flow-field layout is one crucial task for optimizing fuel cells. These cell components perform several functions, including charge transport or gas and water transport throughout the cell just to name a few. Overall, the design depends on the fuel cell ... En savoir plus
Surfaces with water contact angle greater than 150º are super-hydrophobic in nature and possess extraordinary water repelling properties. Various researches on wettability of textured surfaces in recent years have shown that texturing surfaces with micron-sized and nanosized patterns ... En savoir plus
The initiation in numerical modeling of welding with COMSOL Multiphysics® is proposed to the 2nd year students of the professional master program «Processes, Controls, Metallic Materials: Nuclear Industry» (PC2M) of University of Burgundy, France since 2016 within the module «Simulation ...

When the dimensions of the material approach is a comparable size to the phonon mean free path, heat flow enters a new regime, the nanoscale. The Fourier and Cattaneo Equations describe bulk heat flow well, but radiative boundary terms must be considered when modeling nanoscale heat ... En savoir plus
Over the past two decades, extensive research has been conducted on ultraviolet (UV) photodetectors (PDs) because of their potential applications across various fields including military, medicine, environmental monitoring, and deep space explorations. To fabricate solar-blind UV PDs ... En savoir plus
