Use of a Distributed Micro-sensor System for Monitoring the Indoor Particulate Matter Concentration in the Atmosphere of Ferroalloy Production Plants
(Peer reviewed; Journal article, 2022)Airborne particulate matter (PM) is a concern for both occupational health and the environment, and, in the ferroalloy industry, the level of such particles in the air can be considerable. Small, low-cost sensors for ... -
Use of concentric hele-shaw cell for the study of displacement flow and interface tracking in primary cementing
(Peer reviewed; Journal article, 2021)We present our new designed concentric Hele-Shaw cell geometry with dynamic similarity to a real field wellbore annulus during primary cementing, and then, the results of displacement flow of Newtonian and yield-stress ... -
The Use of Eutectic Fe-Si-B Alloy as a Phase Change Material in Thermal Energy Storage Systems
(Journal article; Peer reviewed, 2019)Fe-26.38Si-9.35B eutectic alloy is proposed as a phase change material (PCM) as it exhibits high latent heat, high thermal conductivity, moderate melting point, and low cost. For successful implementation of it in the ... -
The Use of Extracellular Membrane Vesicles for Immunization against Francisellosis in Nile Tilapia (Oreochromis niloticus) and Atlantic cod (Gadus morhua L.)
(Peer reviewed; Journal article, 2021)Francisellosis in fish is caused by the facultative intracellular Gram-negative bacterial pathogens Francisella noatunensis ssp. noatunensis and Francisella orientalis. The disease is affecting both farmed and wild fish ... -
The use of hydrogen as a potential reductant in the chromite smelting industry
(Peer reviewed; Journal article, 2022)The chromium (Cr) content of stainless steel originates from recycled scrap and/or ferrochrome (FeCr), which is mainly produced by the carbothermic reduction of chromite ore. Ever-increasing pressure on FeCr producers to ... -
Use of metal-organics based solvents for CO2 capture
(Journal article; Peer reviewed, 2014)There are a number of metal-organic compounds that can loosely be considered CA mimics and which are known to absorb CO2 directly from the atmosphere. The metal-organic complex, {Zn[N[CH2(2-py)]3](μ-OH)}2(NO3)2 (I), is one ... -
Using machine learning-based variable selection to identify hydrate related components from FT-ICR MS spectra
(Peer reviewed; Journal article, 2022)The blockages of pipelines caused by agglomeration of gas hydrates is a major flow assurance issue in the oil and gas industry. Some crude oils form gas hydrates that remain as transportable particles in a slurry. It is ... -
The Utilization of Bauxite Residue with a Calcite-Rich Bauxite Ore in the Pedersen Process for Iron and Alumina Extraction
(Peer reviewed; Journal article, 2021)Metallurgical grade alumina is produced worldwide through the well-known Bayer process, which unavoidably generates bauxite residue (BR, also known as red mud) in almost equal amounts to alumina. This study aims the ... -
Utilization of dual - PSA technology for natural gas upgrading and integrated CO2 capture
(Peer reviewed; Journal article, 2012)In this study, we have considered Pressure Swing Adsorption (PSA) technology natural gas purification and integrated CO2 capture. We present the utilization of Dual-PSA technology for obtaining pipeline-quality methane and ... -
