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 ...
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, ...
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 ...
Effect of outdoor temperature on the power-conversion efficiency of newly synthesized organic photosensitizer based dye-sensitized solar cells
(
Elsevier B.V.
, 2018 , Article)
In this work, organic photosensitizer has been synthesized for dye-sensitized solar cells (DSSCs). The solar cells then fabricated have been characterized by photocurrent-voltage characteristics and electrochemical impedance ...
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 ...
Zero-bias photocurrents in highly-disordered networks of Ge and Si nanowires
(
Institute of Physics Publishing
, 2015 , Article)
Semiconducting nanowire (NW) devices have garnered attention in self-powered electronic and optoelectronic applications. This work explores and exhibits, for the first time for visible light, clear evidence of the zero-biased ...
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 ...
