[3] Department of Statistics, Miami University, Oxford, OH, USA

Introduction: Bone tissue has a limited ability for regeneration; critically sized defects cannot self-heal and require medical intervention. Bone tissue engineering (TE) circumvents this issue by growing replacement bone tissue from the patient’s own cells inside scaffolds. TE ... Read More

Modeling of Epithelial Sheet Deformation Under External Force Applied by a Migrating Cell

M. A. Akhmanova [1], A. Ratheesh [1], D. E. Siekhaus [1],
[1] Institute of Science and Technology Austria, Klosterneuburg, Austria

Mechanics of living cells and tissues play a central role in many phenomena, from tissue shape formation (morphogenesis) to migration of cells within tissues. One prominent example is the epithelia – a sheet of cells tightly attached to one another. It provides a physical barrier to ... Read More

Non-mechanical micropumps, which does not required moving parts, have prominent role in several biomedical microsystems such as drug delivery, and lab on a chip. Electroosmotic micropump is a non-mechanical micropump that is used to move electrically neutral fluids through very small ... Read More

石墨烯包裹海绵处理水面原油泄露问题

王永超 [1], 葛进 [1],
[1] 中国科学技术大学

海上石油泄漏不仅造成资源的浪费,还长期威胁着脆弱的生态系统。然而浮油具有面积大、油层薄、粘度大的特点,难以采用传统的技术和材料来有效地处理。作者利用石墨烯海绵疏水亲油、导电的特点,设计了一种原位加热的方法,有效地较低了原油的粘度,增大了油在海棉里的扩散系数,在解决快速吸附高粘度原油这一世界性难题方面取得了突破性进展。 在这个研究工作中,作者发现很难在实验上获得此方法的能量消耗情况,为了回答这个问题,作者应用 COMSOL® 软件,模拟了石墨烯海绵加热吸油的热传导过程。运用电流模块,模拟石墨烯泡沫通电加热升温的过程,用热传导模块模拟热量通过石墨烯泡沫传递到油、水 ... Read More

Design for Reliability and Robustness through Probabilistic Methods in COMSOL Multiphysics with OptiY

T.-Q. Pham[1], H. Neubert[2], and A. Kamusella[2]
[1]OptiY e.K., Aschaffenburg, Germany
[2]Institute of Electro-Mechanical and Electronic Design, TU Dresden, Germany

One challenge in designing micro-electromechanical systems (MEMS) is considering the variability of design parameters caused by manufacturing tolerances and material properties. The function of MEMSs is significantly influenced by this variability, which can be represented in terms of ... Read More
