Thispaperwilldiscussaboutthecomparativestudyofmechanicalproperties and magnetic properties for manganese zincferrite (Mn0.8Zn0.2Fe2O4) synthesized by conventional ballmilling method and self combustion method. Both sampleswere comparedon theirmechanical properties andmagneticproperties by using microhardness Vickers and ImpedanceAnalyzer. Morphology and structure of Mn0.8Zn0.2Fe2O4werecharacterizedbyusingX-RayDiffraction,FieldEmissionScanning Electron Microscope (FESEM), and EnergyDispersive X-Ray (EDX). The catalyst characterization wasperformed using Temperature Program Reduction (TPR).Fromthecomparison,ithasbeenshownthatMn0.8Zn0.2Fe2O4synthesis by self combustion method has better mechanicalproperties(75.83HVN)andbettermagneticpropertieswithsuperiorinitialpermeability(2.5x103)andRelativeLossFactor

Zulfa izza Mohamed @ hashim, Mohamad Khairudin bajuri, rohaida Mohd. saat, Mohd. Yakub@ Zulkifli, Mohd.

Brainfunctions that neuroscience studies of different approacheshave totally entrusted to the neurons are considered fromthe Islamic perspective as activities which could traverseacrossdiverseissues,includingmatterspertainingtoreligiousresponsibilities of a Muslim. The current constraints due tocompartmentalization of knowledge could lead to confusionand/or conflicts among students, educators and the Muslimcommunity from the various conventional science streams.In addition, individuals with Islamic studies backgroundhave different understanding and usage of terms which arecommonly difficult to explain to those who are educatedin the conventional science stream. Non-comprehensiveunderstandingofthetwopartiesonspecificissuescouldresultin a clash of views and misunderstanding, thus, leading toanyarisingproblematicissuesbeingunsuccessfullyaddressed.This study focused on memorization activities and the useof reinforcements; two common activities associated to theprocess of formal learning.

Muhammad shahazmi Mohd Zambri, Norani Muti Mohamed, Chong Fai KaitElectrochromic materials can change their optical propertiesreversibly for an applied potential due to electrochemicaloxidation and reduction. Electrochromic polymer likepolyaniline (PANI) is one of the most promising materialswhere its colour can be controlled electrically. However, theelectrochromically deposited polyaniline exhibit substantialresistivity which is attributed to the lack of conductingpathwaysatthenanoscaleassociatedwithrandomdepositionmorphology. This paper describes the study in developingelectrochromic material using carbon nanotubes (CNTs)as the filler.
