Publication A Method Of Lines Approach In The Numerical Solution Of 1-Dimensional Schrodinger's Equation(Canadian Center of Science and Education, 2012) ;Lawal Sa’adu ;M. A. Hashim ;Karsono A. DasukiBahrom SanugiThis paper discusses the numerical solution of the 1-dimensional Schrödinger equation using method of lines approach (MOL) where the spatial dimension is discretize using some finite difference approximation leaving the time dimension to be the only independent variable in the resulting system of initial value problems. The effect of changing the discretization size on the stability of the solution procedure with respect to the absolute stability property of the numerical method used has been studied. In the study the use of Simpson’s rule in MATLAB has also been incorporated. The result indicates that there is some relationship between the discretization size and the convergence property. Further work will look into the modeling this equation to the application in Physics. - Some of the metrics are blocked by yourconsent settings
Publication Supercapacitor Based On A Commercially Prepared Hydroxyl Multiwalled Carbon Nanotubes With Hybrid Polymer Electrolyte(Canadian Center of Science and Education, 2013) ;M. A. Hashim ;Lawal Sa’adu ;Masbudi bin BaharuddinKarsono A. DasukiA separator is prepared from the resulting mixture of hybrid polymer electrolyte polyvinyl alcohol (PVA) (70%) and Phosphoric acid (H3PO4) (30%) immersed in the solution of the combination of polymethyl (methacrylate) and lauroyl chitosan (PLC), for supercapacitor application. The Electrochemical Impedance Spectroscopy (EIS) was conducted twice at normal temperature in an interval of Seven days with very high electrical conductivity of to be 6.42 × 10-4 S cm-1 and 1.84 × 10-4 S cm-1 within these intervals respectively and very low resistance. The supercapacitor was then fabricated using a Commercially Prepared Multi-walled Carbon Nanotube (CPMWCNT) which was sized to an area of 3.5 cm2 and assembled in an innovative supercapacitor tester. The result indicates a relatively high efficiency of about 90% and also exhibited long and excellent cycleability of life time (>1000 cycles) under different voltage windows. - Some of the metrics are blocked by yourconsent settings
Publication Supercapacitors Based On Activated Carbon And Polymer Electrolyte(PAK Publication Group, 2012) ;Mohd Azman Bin Hashim @ismail ;Lawal Sa’aduKarsono A. DasukiThe supercapacitors are characterized by faster discharge rate and easy for maintenance. Their demand is predicted to be most extensive in frequency regulation applications. The other area for significant growth is in regenerative braking for grid–connected light rail systems. In this research we fabricated a Supercapacitor using a commercially prepared Activated carbon which was sized to an area of 1 cm2 and combinations of two electrolytes solutions; polymer electrolyte polyvinyl alcohol (PVA) and Phosphoric acid (H3PO4) assembled in an innovative supercacitor tester. The result indicates a relatively high efficiency of about 90 % and also exhibited long cyclability of life time under different voltage windows. - Some of the metrics are blocked by yourconsent settings
