Enzymatic biofuel cells (EBFCs) are miniature, implantable power sources, which use enzymes as catalysts to perform redox reaction with biological fuels such as glucose. In this study using COMSOL Multiphysics, we use an EBFC chip, having three dimensional, highly dense micro-electrode arrays, fabricated by C-MEMS micro-fabrication techniques. Glucose oxidase (GOx) is immobilized on anodes for ...

Singlet oxygen (1O2) is the major cytotoxic agent in photodynamic therapy (PDT). The reaction between 1O2 and tumor cells defines the treatment efficacy. Based on a previously developed model that incorporates the diffusion equation for the light transport in tissue and the macroscopic kinetic equations for the generation of the singlet oxygen, the distance-dependent reacted 1O2 is numerically ...

In recent years, a number of numerical and finite-element-methods in particular - some implemented in COMSOL - have been developed to investigate various properties of superconducting materials. Following converse conclusions by different models regarding similar physical phenomena, the consistency of these models has been of increased interest. In this publication the accordance of an ...

We present here our work on deconvolution of a magnetic probe to mesure electromagnetic emissions in near-field zone. To achieve this work,we have chosen a rectangular waveguide (WR90) as a radiating structure.Theoritical near-field is simulated using a FEM software (COMSOL) and also obtained by using a program based on transverse operator method (TOM), that lead to a very good field ...

The fabrication of piezo aluminium composite modules for sensor and actor applications with mass production technologies is in the scope of the SFB/Transregio 39 PT-PIESA project funded by the (German Research Foundation). After forming of cavities with a width of 0.3 mm into aluminium sheets by micro impact extrusion and the insertion of 0.25 × 0.25 mm2 piezo rods, a joining of the rods into ...

Like humans, horses can develop a variety of dental problems. Different equine diseases occur in different areas of the equine cheek tooth or its surrounding tissues. With a realistic simulation of a chewing cycle it can be possible to link mechanical phenomena such as high stress in distinct areas to commonly occurring diseases. According to different angles of the acting chewing force, ...
Coupled Gas Flow and Thermal and Reactive Transport in Porous Media for Simulating Waste Stabilization Phenomena in Semi-Aerobic Landfill

Semi-aerobic landfill has interesting structure that passively provides the atmospheric oxygen into landfilled waste due to the heat convection generated by the decomposition of landfilled waste. There are limited studies on the mechanisms of the oxygen transport. This paper presents the governing equations and parameter estimation methods for the numerical simulation of the gas fluid flow and ...

This paper showed: * The electronic states of core-shell tetrapod with various shell thickness were calculated. Lowest 20 electron and hole wave functions have A1 or T2 symmetry. * At t=1.2 nm, the carriers separation is not serious, core-shell tetrapod is not apparent type II heterostructure. * Exciton states were investigated as a function of t. For large t, the lowest exciton state has T2 ...

Groundwater is a key factor affecting mine operations worldwide. On one hand, both underground and open pit mines need to pump out groundwater in order to proceed with mineral extraction and increase the stability of rock slopes. On the other hand, groundwater abstractions can produce undesired environmental and social impacts, which should be anticipated in the environmental impact assessments ...

The Swedish Organization for Radioactive Waste (SKB) is considering disposal High Level Wastes in a deep underground repository. Bentonite clay is planned to be used in the near-field of the waste packages as buffer material. The buffer is expected to provide a favorable environment with limited radionuclide migration due to slow diffusion and retardation by sorption and cation-exchange effects. ...
