Enhanced photovoltaic performance with co-sensitization of a ruthenium(ii) sensitizer and an organic dye in dye-sensitized solar cells
(
Royal Society of Chemistry
, 2016 , Article)
Co-sensitization is demonstrated to be an effective technique to enhance the efficiency of dye-sensitized solar cells, where an efficiency of 9.23% is achieved by mixing N3 and RK-1 dyes. The assembled solar cells are ...
Enhanced photovoltaic performance of dye-sensitized solar cells using TiO2-graphene microplatelets hybrid photoanode
(
IEEE Electron Devices Society
, 2016 , Article)
Hybrid photoanodes for dye-sensitized solar cells (DSSCs) were prepared by simple addition of graphene (GR) microplatelets to TiO 2 nanoparticulate paste. Transmission electron microscopy was used to confirm the presence ...
Correlating structure and electronic band-edge properties in organolead halide perovskites nanoparticles
(
Royal Society of Chemistry
, 2016 , Article)
After having emerged as primary contenders in the race for highly efficient optoelectronics materials, organolead halide perovskites (OHLP) are now being investigated in the nanoscale regime as promising building blocks ...
Intercalation of ionic liquids into bentonite: Swelling and rheological behaviors
(
Elsevier B.V.
, 2016 , Article)
In this study, direct intercalation of three different green ionic liquids (ILs) having different salt and cation sizes into bentonite interlayer is investigated. The ILs covered in this study are: 1-hexyl-3-methylimidazolium ...
Ceramic membrane filtration of produced water: Impact of membrane module
(
Elsevier B.V.
, 2016 , Article)
Produced water (PW) generated from oil exploration requires rigorous removal of suspended matter (free oil and particulate solids) as tertiary treatment (downstream of hydrocyclone and gas flotation) if it is to be re-injected ...
Thermodynamic investigation of hydrogen enrichment and carbon suppression using chemical additives in ethanol dry reforming
(
Elsevier Ltd
, 2016 , Article)
In this study, a thermodynamic equilibrium analysis has been performed on ethanol dry reforming in presence of commonly used reducing agents such as glycine, hydrazine, urea and ammonia. The effect of these agents on ...
Heat transfer enhancement of nanofluids using iron nanoparticles decorated carbon nanotubes
(
Elsevier Ltd
, 2016 , Article)
Enhancing heat transfer in thermal fluid systems can contribute significantly towards the improvement of thermal efficiency resulting in reducing energy consumption and hence carbon emission. Conventional fluids like water ...
Synthesis and characterisation of Co2+-incorporated ZnO nanoparticles prepared through a sol-gel method
(
Elsevier B.V.
, 2016 , Article)
The properties of ZnO nanoparticles were modified by doping them with cobalt ions (Co2+) in various compositions through a sol-gel route. The Co2+-doped ZnO nanoparticles were characterised using X-ray diffraction (XRD), ...
Enhancing oil removal from water using ferric oxide nanoparticles doped carbon nanotubes adsorbents
(
Elsevier B.V.
, 2016 , Article)
Oil contaminated water is one of the challenges in water resources management. It is crucial to remove the oil droplets from water in order to meet the discharge regulations set by the environmental authorities. Carbon ...
Modification of Pd/CeO2 catalyst by Atomic Layer Deposition of ZrO2
(
Elsevier
, 2016 , Article)
Modification of a 1 wt% Pd/CeO2 catalyst by Atomic Layer Deposition of thin ZrO2 films was studied. Calcination of the unmodified Pd/CeO2, prepared by precipitation of aqueous Ce(NO3)3 solutions, with Pd added by impregnation, ...
