Numerical Simulation of Non-Linear Models of Reaction—Diffusion for a DGT Sensor
In this work, we present a novel strategy for the numerical solution of a coupled system of partial differential equations that describe reaction–diffusion processes of a mixture of metals and ligands that can be absorbed by a sensor or a microorganism ...

A Comparison of Bimolecular Reaction Models for Stochastic Reaction Diffusion Systems [PDF]
Stochastic reaction-diffusion models have become an important tool in studying how both noise in the chemical reaction process and the spatial movement of molecules influences the behavior of biological systems. There are two primary spatially-continuous

The Ti/c-Si solid state reaction : III. The low-temperature reaction kinetics [PDF]
Thin Ti layers (≈10nm) are grown on top of a clean Si(111) substrate. Heating these layers initiates a solid state reaction, yielding a monosilicide phase at ≈350°C and a C49 disilicide at ≈450°C.

Oxygen Consumption Characteristics in 3D Constructs Depend on Cell Density
Oxygen is not only crucial for cell survival but also a determinant for cell fate and function. However, the supply of oxygen and other nutrients as well as the removal of toxic waste products often limit cell viability in 3-dimensional (3D) engineered ...
