A separator is prepared from the resulting mixture of hybrid polymer electrolyte polyvinyl alcohol (PVA) (70%) and Phosphoric acid (H 3 PO 4 ) (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 cm 2 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.

Abstract. Gold nanoparticles (GNPs) have been known as an excellent characteristic for Local Surface Plasmon Resonance (LSPR) sensors due to their sensitive spectral response to the local environment of the nanoparticle surface and ease of monitoring the light signal due to their strong scattering or absorption. Prior the technologies, GNPs based LSPR has been commercialized and have become a central tool for characterizing and quantifying in various field. In this review, we presented a brief introduction on the history of surface plasmon, the theory behind the surface plasmon resonance (SPR) and the principles of LSPR. We also reported on the synthetization as well of the properties of the GNPs and the applications in current LSPR sensors.

This 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.
