Integration of temperature and dust effects in siting large PV power plant in hot arid area
(
Elsevier Ltd
, 2013 , Article)
Recently, solar PV technologies witnessed a commercial vigor due to their tremendously decreasing prices. However, these technologies are vulnerable to dust and temperature which can significantly degrade their efficiency. ...
Carbon dioxide sequestration and methane removal from exhaust gases using resorcinol-formaldehyde activated carbon xerogel
(
Springer
, 2013 , Article)
The world is faced with intrinsic environmental issues. Among these issues, the minimization of greenhouse gas emission to acceptable levels presents a high priority. This study seeks to help to reduce the greenhouse effect ...
Influence of micro-and mesoporosity of resorcinol-formaldehyde xerogels on adsorption
(
Mary Ann Liebert
, 2013 , Article)
Effects of micro-and mesoporosity of resorcinol-formaldehyde xerogels (RFXs) on the adsorptive properties of crystal violet (CV) were investigated. RFXs were synthesized at different pH values, and corresponding pore ...
Photo-oxidative enhancement of polymeric molecular sieve membranes
(
Nature Research
, 2013 , Article)
High-performance membranes are attractive for molecular-level separations in industrial-scale chemical, energy and environmental processes. The next-generation membranes for these processes are based on molecular sieving ...
Thin, flexible supercapacitors made from carbon nanofiber electrodes decorated at room temperature with manganese oxide nanosheets
(
Hindawi Publishing Corporation
, 2013 , Article)
We report the fabrication and electrochemical performance of a flexible thin film supercapacitor with a novel nanostructured composite electrode. The electrode was prepared by in situ coprecipitation of two-dimensional ...
Bromate reduction by ultraviolet light irradiation using medium pressure lamp
(
Taylor & Francis
, 2013 , Article)
Bromate reduction in water by ultraviolet irradiation using medium-pressure lamps (UV-M) emitting light in the range of 200-600 nm has been investigated. Effects of certain experimental parameters including the initial ...
Optical and electrical properties of porous silicon impregnated with congo red dye
(
American Institute of Physics
, 2013 , Article)
Incorporation of molecules into porous silicon (PS) matrix is of particular interest for potential utilization in hybrid organic-semiconductor devices. In this study, the incorporation of Congo Red molecules inside luminescent ...
Nitrate removal from water using UV-M/S2O42- advanced reduction process
(
Springer
, 2013 , Article)
In this work, a new process called advanced reduction process (ARP) was used for nitrate removal from water. This ARP process combines sodium dithionite as reducing agent with ultraviolet irradiation using medium pressure ...
Real-time optical character recognition on field programmable gate array for automatic number plate recognition system
(2013 , Article)
The last main stage in an automatic number plate recognition system (ANPRs) is optical character recognition (OCR), where the number plate characters on the number plate image are converted into encoded texts. In this ...
Exchange rate pass-through and inflation dynamics in Tunisia: A Markov-switching approach
(
Kiel Institute for the World Economy
, 2013 , Article)
This paper studies the effect of exchange rate pass-through on inflation in Tunisia for the period 2001 to 2009. The objective is to track inflation regimes for the Tunisian economy and to forecast its determinants. Using ...
