Hydrogen emissions from an electrolysis unit

Hydrogen is expected to play a vital role as an energy carrier in the future decarbonized system. Currently, a large portion of the hydrogen produced comes from the steam reforming of methane present in natural gas, which produces significant amounts of carbon dioxide emissions. However, with the growing need to reduce greenhouse gas emissions,...

Photoelectrocatalytic Degradation of Organic Micropollutants in aqueous solutions using Bismuth Vanadate Photoanodes

As industrialization advances rapidly in pursuit of refining the quality of human life, there has been a release of organic micropollutants (OMPs) such as pharmaceuticals into various water reserves. This has endangered the ecosystem and the possibilities of water recovery. Commonly used tertiary wastewater treatment technologies have proven to,...

A robust material for the production of microfluidic liquid-liquid extraction chips: Evaluation of a robust ALD coating to reduce irradiation-induced surface modifications on polymers and quartz for the usage of microfluidic liquid-liquid extraction chips

Microfluidic extraction is a promising alternative for existing extraction methods of radioisotopes due to the high surface-to-volume ratio. When assessing the compatibility of microfluidic material with the extraction system, there are three critical aspects—compatibility with organic solvents, compatibility with the radiochemistry, and, most...

Modelling and Numerical Investigation of Taylor Flow on the Performance of Electrochemical Flow Cells

Electrochemical reduction of CO2 using renewable energy sources is one of the promising avenues to pursue towards mitigating the emissions of the notorious CO2. However, the CO2 electrolysis in aqueous systems, due to the low solubility of CO2, are severely limited by mass transfer. State of the art review shows that a significant amount of the...

To address the energy demand of the growing world population, the transition from polluting exhaustible energy sources to clean inexhaustible energy sources is imminent. Solar energy is one of the energy sources that has been studied extensively. In particular, the application of solar energy in photoelectrochemical water splitting has gained...

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...

A Clean and Flexible Catalyst Synthesis Method: Metal nanoparticles on a fractal-like nanostructured metal oxide support

A highly porous fractal-like nanostructured metal oxide catalyst support with characteristic dimensions of a few nanometers is formed by producing metal nanoparticles in the gas phase, oxidizing them and depositing/sintering them on a nanofiber network. By admixing nanoparticles in the aerosol phase, these can evenly be distributed in the...

Development of an effective process model for algae growth in photobioreactors

Algae have been a hot topic in recent years due to their potential for several reasons. They have been proposed as an alternative for fossil fuels, a superfood for consumers, a potential CO2 absorber to reduce green house gas emission, feedstock for nutritional and chemical industry, a waste water treatment technique and more. However, the large...

Magnetic Drug Targeting in Human Airway Geometry

Patient specific drug delivery may improve the efficiency of the medicine and reduce the side-effects. In addition to different medicines and dosages, the target site of the medicine can differ from patient to patient. By using drug particles with a magnetic core, and under the influence of a magnetic field, the particles may be steered towards...
