Unraveling Enhanced Activity, Selectivity, and Coke Resistance of Pt–Ni Bimetallic Clusters in Dry Reforming
(Peer reviewed; Journal article, 2021)By introducing Pt atoms into the surface of reduced hydrotalcite (HT)-derived nickel (Ni/HT) catalysts by redox reaction, we synthesized an enhanced active and stable Ni-based catalyst for methane dry reforming reaction. ... -
Unraveling the roles of the reductant and free copper ions in LPMO kinetics
(Peer reviewed; Journal article, 2021)Background: Lytic polysaccharide monooxygenases (LPMOs) are monocopper enzymes that catalyze oxidative depolymerization of industrially relevant crystalline polysaccharides, such as cellulose, in a reaction that depends ... -
Unscented Kalman Filter Based State and Parameter Estimation in Percussive Drilling Systems
(Chinese Control Conference (CCC);1934-1768, Chapter; Peer reviewed, 2019)Down-The-Hole (DTH) percussion tool is recognized for its high average rate of penetration (ROP), when drilling medium hard to very hard rock formations. This ROP which depends on the bit-rock contact conditions at the ... -
Uptake and toxicity of methylmethacrylate-based nanoplastic particles in aquatic organisms
(Journal article; Peer reviewed, 2015)The uptake and toxicity of 2 poly(methylmethacrylate)-based plastic nanoparticles (PNPs) with different surface chemistries (medium and hydrophobic) was assessed using aquatic organisms selected for their relevance based ... -
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 ... -
