Modeling of dual-metal Schottky contacts based silicon micro and nano wire solar cells
(
Elsevier B.V.
, 2014 , Article)
We study solar cell properties of single silicon wires connected at their ends to two dissimilar metals of different work functions. Effects of wire dimensions, the work functions of the metals, and minority carrier lifetimes ...
Synthesis and characterization of Sm3+-doped ZnO nanoparticles via a sol–gel method and their photocatalytic application
(
Springer New York LLC
, 2018 , Article)
Abstract: Spherical ZnO nanoparticles doped by samarium ions were successfully synthesized via a simple sol–gel method. The structures, morphologies, optical properties and surface areas were investigated for all samples ...
Biotransformation of carbon dioxide in bioelectrochemical systems: State of the art and future prospects
(
Elsevier
, 2017 , Article)
Carbon dioxide (CO2) utilization/recycling for the production of chemicals and gaseous/liquid energy-carriers is a way to moderate the rising CO2 in the atmosphere. One of the possible solutions for the CO2 sequestration ...
Photoresponse of silicon with asymmetric area contacts
(
Institute of Physics Publishing
, 2016 , Article)
We report on high performance metal-semiconductor-metal (MSM) photosensors based on asymmetric metal pad areas. The reported devices require a single-step metal deposition, and exhibit large photo response even under ...
Tailoring optical absorption in silicon nanostructures from UV to visible light: A TDDFT study
(
Elsevier Ltd
, 2016 , Article)
The utilization of silicon nanostructures, from quantum dots to nanowires, for photovoltaic applications depends on understanding the effect of their physical structure on their optical absorption properties. In this work, ...
Clogging vs. fouling in immersed membrane bioreactors
(
Elsevier Ltd
, 2018 , Article)
Whilst the fouling of MBR membrane surfaces has been very extensively explored by the academic community, there is an increasingly widespread recognition by practitioners of the issue of clogging of membrane channels with ...
Optimization of magnesium recovery from reject brine for reuse in desalination post-treatment
(
Elsevier Ltd
, 2019 , Article)
In this work, the recovery of magnesium from desalination reject brine through reaction with ammonia has been evaluated and statistically optimized using response surface methodology. The process is based on precipitation ...
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 ...
Molecular Modeling Study toward Development of H2S-Free Removal of Iron Sulfide Scale from Oil and Gas Wells
(
American Chemical Society
, 2018 , Article)
A common problem that faces the oil and gas industry is the formation of iron sulfide scale in various stages of production. Recently an effective chemical formulation was proposed to remove all types of iron sulfide scales ...
