Identification of the methanogenesis inhibition mechanism using comparative analysis of mathematical models

The application of cationic polymers to enhance membrane fluxes in anaerobic membrane bioreactors has been proposed by several authors. However, literature shows contradictory results on the influence of those chemicals on the biological activity. In this research, we studied the effect of a cationic polymer on the production of methane from...

Electric Micro Propulsion: Development of a LaB6 Cathode for Micro Electric Thrusters

There is a trend in the miniaturisation of satellites. They not only become smaller, but lighter and more powerful as well. A large growth in the nano-satellite sector is present in the form of CubeSats. These milk carton size satellites use commercial of the shelf components in order to keep the costs low and to allow for technology...

Temperature, lipid charge and septin dependence of lateral lipid diffusion in biomimetic membrane systems

Plasma membrane dynamics have become increasingly of interest due to recent discoveries on anomalous lipid diffusion in live cells. A specific characteristic has been found in the exponential relation between lateral lipid diffusion and temperature. The finding was reported to be surprising as a linear dependence was theoretically predicted. In...

On direct internal methane steam reforming kinetics in operating solid oxide fuel cells with nickel-ceria anodes

Major operating challenges remain to safely operate methane fuelled solid oxide fuel cells due to undesirable temperature gradients across the porous anode and carbon deposition. This article presents an experimental study on methane steam reforming (MSR) global kinetics for single operating SOFCs with Ni-GDC (gadolinium doped ceria) anodes...

Modelling and design of a flat plate fixed film photoreactor for phenol degradation

This paper presents the mathematical modelling and design of a flat plate photoreactor with a fixed film photocatalyst to degrade phenol. Phenol was used as target pollutant as it is one of the most studied contaminants in photocatalysis and it is present in many of the wastewater streams containing pesticides, drugs, and dyes which cannot be...

Comparative Analysis of Shale Permeability Measurements

Gas has proved to be a successful extractable hydrocarbon resource from shale in the United States. In Europe results have so far been disappointing, but with increasing global energy demand a lot of interest remains in the potential of recoverable shale gas reservoirs. However, the way how the economic potential of shale is mapped is...

Interaction between High-Voltage Cathode Materials and Ionic Liquids for Novel Li-Ion Batteries

The fast-growing market on electronic portable devices is possibly due to the development of Li-ion batteries. Besides, such batteries are the most promising candidates as energy storage media in (hybrid) electric vehicles, in the near future. However, improvements on electrochemical performances and on safety need to be achieved. With respect...

Deposition and atomic force microscopy of individual phthalocyanine polymers between nanofabricated electrodes

Electrical transport in monolayers of phthalocyanine molecular wires and AFM imaging of a single wire bridging two electrodes
