Freeze-dried (lyophilized) drug products offer extended shelf life and improved drug stability within a range of combination products including autoinjectors and pre-filled syringes. A key step in the use of combination products is the reconstitution of the freeze-dried drug product (DP) ... Mehr lesen

Pleural photodynamic therapy (PDT) following surgical resection is a critical treatment for malignant pleural mesothelioma, where accurate light delivery directly impacts treatment efficacy and patient outcomes. A fundamental challenge in PDT dosimetry is the significant deformation of ... Mehr lesen

INTRODUCTION: The paper illustrates the use of COMSOL for obtaining the solution Ψ(x,y,t) as a solution to the time dependent nonlinear Schrödinger equation (NLSE). COMSOL previously was used to solve the time dependent NLSE in Ref.[1] as applied to quantum mechanics, however this is the ... Mehr lesen

The transition to a hydrogen-based, renewable energy economy demands scalable and highly efficient electrolysis technologies. Solid Oxide Electrolysis Cells (SOECs) offer a particularly promising path, outperforming other electrolysis technologies in terms of efficiency and thus ... Mehr lesen

Electrospun nanofibers are widely used in tissue engineering as extracellular matrices (ECMs) due to their ability to support cell adhesion and direct cellular development. Fiber alignment plays a critical role in cellular behavior and is influenced by local electric field orientation ... Mehr lesen

We narrow the consideration to HV cylindrical parts, typically with axial leads located on the opposite sides. They are tens of millimeters long, so at moderate frequencies of up to 10MHz they may be analyzed as lumped elements (not as transmission lines), although in some cases they may ... Mehr lesen

Recent retina implants have been shown to form monochromatic vision with prosthetic visual acuity of 20/438, dependent on the individual pixel size of 100 microns [1]. It is still far from meaningful image formation. Overall, the key challenge in retinal stimulation is the unresolved ... Mehr lesen

Throughout this work, we conduct simulations using the finite-element commercial software COMSOL MULTIPHYSICS. Valley interface states, resulting in acoustic valley Hall topological insulators, have recently become a hot topic in the study of acoustic systems. On the basis of structural ... Mehr lesen

芯粒（Chiplet）被认为是后摩尔时代持续提高芯片性能和集成度的主要技术路径，也是我高端芯片突破国外封锁的关键途径。可靠性评估是实现Chiplet高性能、高安全、高可靠发展的有效保障。 玻璃通孔（TGV）互连技术具有高频电学特征优异、成本低、工艺流程简单、机械稳定性强等应用优势，成为一种实现Chiplet集成的重要解决方案。传统方法通过切片与缺陷形貌观察来验证TGV的应力应变趋势，但该方法受制样机械应力影响且耗时长，降低了学术与产业协作效率。为了探索TGV在电-热-力多物理场作用下的可靠性规律，亟需一种高效、低成本的TGV应力和结构影响的仿真分析方法。 ... Mehr lesen

本文介绍COMSOL Multiphysics在水下物体散射声场建模仿真中的应用，具体工作包括：（1）应用压力声学(pressure acoustics，PA)、声学边界元（pressure acoustics boundary element，PABE）、高频渐近散射（pressure acoustics asymptotic scattering，PAAS）三种方法计算刚性球的散射形态函数和目标强度并同Rayleigh理论解作对比，初步探讨了在做声散射建模仿真时这三种方法的适用范围；（2 ... Mehr lesen
