1. It is feasible to focus and guide nanoparticles with permanent magnets and ferromagnetic particles to achieve clinically significant olfactory dosages. 2. With appropriate magnetophoretic guidance and selective drug release, an olfactory delivery efficiency of more than 20% can be achieved. 3. The optimal particle size range for magnetophoretic guidance is 10−15 µm.

A requirement of the building envelope is to act as environmental separator. Energy is one component that we sometimes wish to control. How can this yield passive benefits such as solar heating? This research focuses on control of thermal radiation energy, and the role windows play as transfer medium between indoor and outdoor environments. A novel concept for passively controlling solar ...

Implantable Collagen sponges are used in Spinal Surgery as Drug Delivery Scaffolds. An optimal concentration of growth factor that strikes a balance between bone growth and adverse diffusion effects is difficult to find. The porous sponge also serves as a scaffold for Osteoblast growth, and fluid shear has been shown to mediate biological effects on that cell type. We use COMSOL Multiphysics ...

Electroosmotic flow of power-law fluids in a slit channel(1D) is analyzed. The governing equations are the Poisson–Boltzmann equation, the Cauchy momentum equation, Generalized Smoluchowski equation and the continuity equation are used to get shear stress, dynamic viscosity, and velocity distribution. Simulations are performed to examine the effects of ?H, flow behavior index, double layer ...

We consider a 3D boundary value problem arising in electrostatics. The potential is stimulated by current sources placed on a cross-section S of the domain. In many applications it is sufficient to know the potential in S. So, one is interested in an appropriate 2D model taking into account that the solution depends on the dimension of the domain. The idea is to find a corresponding 2D ...

The present work aims to develop a blood pressure sensor using MEMS/NEMS technology. A normal blood pressure detector is used externally, but this work mainly aims for designing an implantable nanotube based sensor for continuous monitoring of blood pressure. The use of COMSOL Multiphysics 4.1 acts as a good platform to develop a nano tube based sensor design by using the MEMS module. The ...

MEMS gyroscope technology provides cost- effective method for improving directional estimation and overall accuracy in the navigation systems. This paper presents a tuning- fork gyroscope (TFG)  with a perforated proof mass. The perforated proof mass used in the design enables the reduction of the damping effect. This MEMS based gyroscope was designed using COMSOL Multiphysics 4.2a. This ...

Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that stresses generated do not exceed the endurance strength of the material. In this paper, structural mechanics ...

Metal contaminants and organic pollutants are affecting aquatic environments in urban and industrial zones. Mangrove trees are capable of absorbing metal ions and organic pollutants. To estimate the remediation potential, a two dimensional model of water and substance flow in the soil plant system based on porous media equations was set up. We show that multiphysics approaches also apply to ...

High levels of Indoor Air Quality (IAQ) in Operating Theatres (OT) is an important issue in order to contribute in prevention of Surgical Site Infections (SSI). Despite of specific plant layouts are applied for OT ventilation (e.g. unidirectional flow), the effective use conditions can heavily modify the design microclimate and air quality levels. Medical staff presence and movements and sliding ...
