表面等离激元共振的有限元仿真模拟在单纳米粒子成像和纳米电化学的应用

蒋莹琰 [1], 王伟 [1],
[1] 南京大学化学化工学院

表面等离激元(SPPs)是一种在特定光激发下由金属自由电子振荡产生的沿金属与电介质界面传播的电磁波。作为光与物质相互作用的一种重要形式,SPPs在近场光学,表面增强光谱以及化学和生物传感等领域都有着广泛的应用。表面等离激元共振显微术(SPRM)利用全内反射的消逝场激发SPPs,在金属薄膜表面传播的SPPs与纳米粒子的散射波相互作用产生独特的波形图案。由于SPRM所具有的波形图案较为复杂,我们利用COMSOL Multiphysics的波动模块构建了计算模型对其进行仿真模拟,并应用于SPRM的单纳米粒子成像和纳米电化学领域的研究分析。 首先 ... En savoir plus

Solar Active Plaster for the Renovation of Existing Buildings

S. Malz [1],
[1] Ostbayerische Technische Hochschule Regensburg, Regensburg, Bayern, Germany

The building sector, especially considering existing buildings, requires an enormous part of a country's energy demand. In the course of the renovation of buildings, therefore, less emphasis is placed on the protection of the appearance of historical/older buildings than on their future ... En savoir plus

COMSOL Multiphysics® Bio-Cellular Tunneling Model

E. Lacatus [1],
[1] Polytechnic University of Bucharest, Romania

The emerging technologies related to AI and Quantum Computing are shifting the nano-bio-info paradigm, reconsidering the presently assumed bioenergetic processes of the living cells. Thus, a key process as ATPase can be considered through a model governed by quantum field theory (QFT) ... En savoir plus

E. Lacatus [1],
[1] Polytechnic University of Bucharest, Romania

Bio-compatibilized G/GO/RGO composite structures with embedded stearic acid on a bilayer structure model, biomimicking the cellular lipid bilayer are introduced through successive models. The solvent accessible surface of the models (van der Waals surface) and the related MD values were ... En savoir plus

PIR Sensor Modeling and Simulation Using COMSOL Multiphysics® and its Ray Optics Module

M. Maaspuro [1],
[1] School of Electrical Engineering, Aalto University, Finland

PIR (Passive Infrared) sensor is the most widely used motion sensor for occupancy detection in building automation applications. Normally, only the binary information indicating presence or absence is used. However, an advanced analysis of the PIR sensor analog signal can results in more ... En savoir plus

Collecting Photons from an STM Microscope

H. Cabrera [1], B. Zengin [2],
[1] Laboratory for Solid State Physics, ETH Zürich, Zürich, Switzerland
[2] Department of Physics, Istanbul Technical University, Turkey

We modify a Tunnel Effect Microscope (STM) with the purpose of analyzing the local production of photons in the electrostatic junction during the image taking process. The novelty of this project compared to previous studies is that it is intended to be developed from the beginning as ... En savoir plus

Modeling Confinement in Quantum Dot Solar Cells

J. Liu [1], M. Zubaer Hossain [1],
[1] Department of Mechanical Engineering, University of Delaware, Newark, DE, USA

The efficiency of the first and second generations of solar cell has hardly seen dramatically increase over the years, in which most PV cells cannot use about 55% of the energy of sunlight because a single material can not capture the entire spectrum of sunlight. To achieve the objective ... En savoir plus

Atmospheric Microwave Plasma

T. S. Marquardt [1], D. F. Shewamene [1], J. J. Swanson [1],
[1] Integrated Engineering, Minnesota State University, Mankato, MN, USA

Plasma gasification of biomass is emerging as an efficient way to reduce the carbon foot print of waste management while generating renewable energy. In general, gasification is a process where electromagnetic wave energy is used to heat biomass sufficiently to convert the bio-mass to ... En savoir plus
