Photoconductive response of strained silicon nanowires: A Monte Carlo study
(
AIP Publishing LLC.
, 2014 , Article)
Using Ensemble Monte Carlo simulations, the photocurrent in a 500 nm long strained [110] silicon nanowire with diameter of 3.1 nm is investigated. It was observed that a phototransistor based on this nanowire can have ...
Catalytic evaluation of nickel nanoparticles in methane steam reforming
(
Elsevier
, 2016 , Article)
Development of a highly efficient and coke-resistant, nickel nanoparticles (Ni.NPs) based catalyst in the steam reformation reaction of methane is reported. The catalyst was prepared by dispersing Ni-nanoparticles over ...
Kinetics of CO2 Adsorption/Desorption of Polyethyleneimine-Mesoporous Silica
(
Wiley-VCH Verlag
, 2017 , Article)
The kinetics of adsorption of CO2 on solid sorbents based on polyethyleneimine/mesoporous silica (PEI/MPS) was studied by following the mass gain during CO2 flow. Linear (PEI-423) and branched (PEI-10k) polymers were ...
High-efficiency c-Si based interdigitated point contact back heterojunction solar cells
(
Springer New York LLC
, 2017 , Article)
We report on the modeling and performance optimization studies of point contact back heterojunction (BHJ) solar cells. BHJ solar cell technology is a combination of front heterojunction (a-Si:H/c-Si) solar cell technology ...
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 ...
Ni-based nano-catalysts for the dry reforming of methane
(
Elsevier B.V.
, 2019 , Article)
Development of a highly efficient and coke-resistant, nickel based nano-catalyst in the carbon dioxide reformation of methane is reported. The alumina supported Ni-based catalyst with a metal loading of 5wt% was prepared ...
Phyllosilicate nanoclay-based aqueous nanoparticle sorbent for CO2 capture at ambient conditions
(
Elsevier Ltd
, 2017 , Article)
We report a new and effective aqueous sorbent for CO2 capture at ambient conditions based on aminopropyl magnesium phyllosilicate nanoparticles (aminoclay). Combining the advantages of both liquid and solid amine sorbents, ...
The effect of sulfur dioxide on the activity of hierarchical Pd-based catalysts in methane combustion
(
Elsevier B.V.
, 2017 , Article)
SO2 poisoning of methane oxidation over alumina-supported, Pd@CexZr1−xO2 nanoparticle catalysts was systematically studied by means of advanced PhotoElectron Spectroscopy (PES) methods. The Pd@CexZr1−xO2 units were synthesized ...
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, ...
