This work reports facile and well-controlled synthesis of a number binary, ternary, quaternary nanocomposites using combinations metal oxides (CuO, NiO), multiwalled carbon nanotubes (MWCNTs), conducting polymer polyaniline (PANI) for application as electrode in supercapacitor. X-ray diffraction electron microscopic analyses confirmed the formation different composites made binary CuO@NiO, ternary CuO@PANI/MWCNT, NiO@PANI/MWCNT, CuO@NiO/PANI/MWCNT nanocomposites. Such combination materials...
Abstract Many field tests of the steam assisted gravity drainage (SAGD) process have been conducted and shown that is a technically effective one at extracting oil from heavy bitumen reservoirs. However, it has not firmly established whether technology operated optimized conditions to yield maximum economic returns. This especially important because typically SAGD depends on combustion natural gas generate this dominant cost. The cost can be significant when prices are high. research...
Abstract Steam-Assisted Gravity Drainage (SAGD) is a commercial in situ recovery technology that effective at recovering heavy oil and bitumen. However, generation of steam by combusting natural gas adversely impacts the economics process, especially when price high, as has been case lately. It shown solvent additives can improve production rates, or least maintain similar rates with reduced injection. This basis Expanding Solvent (ES-SAGD) process. The key idea plus better than alone to...
Li10GeP2S12 (LGPS) solid electrolyte is not affordable due to the high cost of Ge metal, making it economically unviable despite being a lithium superionic conductor. The synthesis such electrolytes much more time- and energy-consuming needs an inert environment. Here, we report Si (silicon)-based composition [Li10SiP2S12 (LSiPS)] make cost-effective through microwave heating (MW). total time for processes, including ball milling, rate, dwell time, ∼120 min, less than previous reports. We...
Transition-metal compounds (TMCs) such as oxides, hydroxides, and sulfides are well-known pseudocapacitive materials whose capacitance has been shown to improve by combining them with different carbon nanostructures (CNSs). Here, we report a systematic investigation on the influence of six CNSs: single-walled nanotubes (SWCNTs), functionalized multiwalled nanotubes, graphene oxide (GO), reduced GO (rGO), nanoplatelets Ni(OH)2 nanostructures, focusing their electrochemical properties for...
The decomposition kinetics of four synthetic alkaline earth metal carbonates (MgCO3, CaCO3, SrCO3 and BaCO3) was studied under non-isothermal conditions from thermo-gravimetric measurements as compared to. integral approximation method Coats Redfern used to determine the kinetic parameters for processes. reactions followed mostly first order activation energy increased with increase in molecular mass carbonates. change enthalpy processes also calculated energies process all higher than...
A nanohybrid containing 2 mol% La<sup>3+</sup>doped MnO<sub>2</sub>and carbon nanotubes produced hydrothermally exhibits a specific capacitance of ∼1530 F g<sup>−1</sup>at 1 g<sup>−1</sup>and 92% capacity retention after 5000 cycles showing its potential as electrode for supercapacitors.
Abstract There are vast heavy crude oil resources worldwide that relatively uneconomical to produce and upgrade. However, there novel processes available can be employed in a downhole environment upgrade these oils, resulting significantly less sulphur content, lowered densities viscosities. A process is especially favourable for implementation the use of situ combustion generate reactive upgrading gases, such as CO, possibly H2, drive over near-wellbore heated bed catalyst. Two laboratory...
Nickel oxide (NiO) nano-structures were synthesized on random multi-walled carbon nanotubes (MWCNTs) via hydrothermal route followed by calcination in air for the electric double layer capacitor electrode application (EDLC).XRD studies revealed crystallinity of NiO nanostructures. The average particle size these nanostructures was found to be 25 nm. ratio peak current (Ipr), 0.99 which confirmed that redox reaction a quasi-reversible process specific NiO/CNTs capacitance reached up 650 F/g 1...
