Efficient Electrochemical Reduction of CO2 to CO by Ag-Decorated B-Doped g-C3N4: A Combined Theoretical and Experimental Study
(Peer reviewed; Journal article, 2022)Electrochemical CO2 reduction (ECR) has received great attention in energy conversion and CO2 mitigation. In recent years, graphitic carbon nitride (g-C3N4) has been regarded as a very promising support for metal nanoparticles ... -
Measuring filter-cake cohesive strength and flowability
(Peer reviewed; Journal article, 2022)The filter-cake has a critical role in temporarily reducing the permeability of the wellbore to prevent issues such as lost circulation, formation damage, wellbore collapse and differential sticking. The filter-cake's ... -
Method for reconstruction of axisymmetric capillary wave surface topography using inverse ray-tracing of refracted laser sheet
(Peer reviewed; Journal article, 2022)Capillary waves can be used to measure the fundamental fluid properties such as surface tension as well as, potentially, the viscosity of Newtonian fluids. This requires the measurement of various wave parameters, mainly ... -
On the numerical discretization of a tumor progression model driven by competing migration mechanisms
(Peer reviewed; Journal article, 2021)In this work we explore a recently proposed biphasic cell-fluid chemotaxis-Stokes model which is able to represent two competing cancer cell migration mechanisms reported from experimental studies. Both mechanisms depend ... -
Rayleigh and Wood anomalies in the diffraction of acoustic waves from the periodically corrugated surface of an elastic medium
(Peer reviewed; Journal article, 2016)By the use of the Rayleigh method we have calculated the angular dependence of the reflectivity and the efficiencies of several other diffracted orders when the periodically corrugated surface of an isotropic elastic medium ... -
The Role of Micro Gas Turbines in Energy Transition
