Developing ANN-Kriging hybrid model based on process parameters for prediction of mean residence time distribution in twin-screw wet granulation
(
Elsevier B.V.
, 2019 , Article)
Artificial neural network (ANN) modelling is applied to predict the mean residence time of pharmaceutical formulation in a twin-screw granulator. Process parameters including feed flow rate, screw speed, and liquid to solid ...
Bio-carrier and operating temperature effect on ammonia removal from secondary wastewater effluents using moving bed biofilm reactor (MBBR)
(
Elsevier B.V.
, 2019 , Article)
This study investigates the impact of bio-carriers' surface area and shape, wastewater chemistry and operating temperature on ammonia removal from real wastewater effluents using Moving bed biofilm reactors (MBBRs) operated ...
Novel controlled synthesis of nanoporous carbon nanorods from resorcinol-formaldehyde xerogels
(
Elsevier B.V.
, 2017 , Article)
A novel approach is discovered to produce carbon nanorods (CNRs) from resorcinol-formaldehyde xerogels. The structure and morphology of CNRs are characterized by pore size analysis, nano-scanning electron microscopy, ...
Impact of Surfactant on the Retention of CO2 and Methane in Carbonate Reservoirs
(
American Chemical Society
, 2018 , Article)
Enhanced gas recovery methods such as foamed CO2 are recommended for depleted gas reservoirs. Viscoelastic surfactant (VES) is a form of a surfactant used for forming CO2 foam. In this study, the impact of VES on CH4 and ...
Multilayer-MCTDH approach to the energy transfer dynamics in the LH2 antenna complex
(
Institute of Physics Publishing
, 2017 , Article)
The multilayer multiconfiguration time-dependent Hartree method is used to study the coupled exciton–vibrational dynamics in a high-dimensional nonameric model of the LH2 antenna complex of purple bacteria. The exciton–vibrational ...
Stability in 3D and 2D/3D hybrid perovskite solar cells studied by EFISHG and IS techniques under light and heat soaking
(
Elsevier B.V.
, 2019 , Article)
We investigate the effect of temperature and light soaking on the stability and charge carrier behavior in triple cation 3-Dimensional (3D) and 2-Dimensional (2D)/3-Dimensional perovskite solar cells (PSCs) using electric ...
Thermodynamic analysis of solar-driven chemical looping steam methane reforming over Cr2O3/Cr redox pair
(
Elsevier Ltd
, 2019 , Article)
Thermodynamic analysis of the Cr2O3/Cr based CH4 reforming (MR) and water splitting (WS) cycle is conducted and the results obtained are reported in this paper. For this study, two process configurations are considered: ...
Sol-gel synthesized NixFe3−xO4 for thermochemical conversion of CO2
(
Elsevier B.V.
, 2019 , Article)
To identify the best suitable metal oxide (MO) to split H2O/CO2, it is critical to investigate the formation of O2 vacancies during thermal reduction (TR) step and the re-oxidation of the MOs via H2O or CO2 splitting (CS) ...
Hydrogen production via solar driven thermochemical cerium oxide-cerium sulfate water splitting cycle
(
Elsevier Ltd
, 2019 , Article)
Production of H2 via water splitting reaction driven by concentrated solar power is one of the promising ways to fulfill the future energy demand. In this investigation, the cerium oxide-cerium sulfate H2O splitting (WS) ...
Synthesis and characterisation of Ni–B/Ni–P–CeO2 duplex composite coatings
(
Springer Netherlands
, 2018 , Article)
Abstract: Binary (Ni–B, Ni–P) and duplex coatings (Ni–B/Ni–P, Ni–B/Ni–P–CeO2) with an inner Ni–B layer were electrodeposited on mild steel substrates. A comparison of the structural, surface, mechanical, and electrochemical ...
