Two Anode Surface processes are examined : Formation of Solid Electrolyte Interphase (SEI) and heating due to Shuttle Current. During charging, higher order sulfur species are reduced at the anode surface, while they are concurrently being oxidized at the cathode. This leads to the formation of a parasitic ‘shuttle’ current. We show that heating due to this shuttle current can lead to large ...

A model for CO2 storage is presented. It is shown that the system is highly dynamic, i.e. results depend strongly on parameter disturbances and numerical features. However, a series of scenario calculations shows that there are invariants, most important: the duration of the early convection phase with high mass transfer rates.

In the field of chemical reaction engineering chemical kinetics and fluid dynamics are described by various mathematical approaches. Such tools help to shorten the time-to-market of novel products and processes. Thanks to the continuously improving computation power, it is possible to consider the kinetics of chemical reactions as source terms in the Navier-Stokes equations. Even a coupling with ...

Aerosol and colloid aggregates are complex fractal-like structures composed of primary spheres. The drag force exerted on a fractal-like object is usually determined by solving numerically the Stokes equation. In this study we calculate it by relating it to a molecule-aggregate collision rate. We create the fractal aggregates with a cluster-cluster aggregation algorithm using the software ...

This paper presents the numerical simulation model for radiocesium leaching and transporting behavior in municipal solid waste (MSW) landfill and discusses on the design for the required geometry and properties of the impermeable final cover and the soil sorption layer, which work for containment of hazardous waste such as radiocesium-contaminated MSW generated by Fukushima Daiichi nuclear ...

Localized calcium events in the endothelial cells (EC) can modulate smooth muscle cell (SMC) calcium (Ca2+) and membrane potential dynamics through release of endothelium derived hyperpolarizing and relaxing factors. Ca2+ levels in the smooth muscle cell (SMC) determine its contractile state.The underlying complex mechanism regulating the SMC Ca2+ levels and ultimately vessel tone remains poorly ...

Radioactive waste repositories include barriers that work to contain the waste, thereby protecting human health and the environment. In deep geological disposal systems, barriers include the natural geological barrier and the engineered barrier system (EBS). The ability of the EBS to limit groundwater flow is important and optimized design solutions are often sought by means of numerical ...

Air supply hoses are also predominantly used in the medical industry to aid in patient oxygen intake. In many situations, the outside of the hose can be contaminated with chemicals, especially if the hose lies on the ground in an environment where chemicals are easily found. Permeation and transport of chemicals into the walls of air supply hoses is a noteworthy problem in the chemical ...

Windows are the thermal weakest places in the external envelop of buildings. This is true for historic windows with original single pane glazing in historic buildings. To reduce the energy consumption and to improve thermal comfort of historic buildings, replacing these windows by modern double glazed windows affects the authentic character of these buildings too much. One way to improve the ...

Rechargeable batteries solve electrification and communication problems. As examples, hybrid battery-diesel generator power supplies efficiently power cell towers in remote locations, detached from the power grid. Large battery banks are used to load level user power requirements, reducing stress on power generation infrastructure. Batteries firm the output capacity of intermittent wind ...
