Aluminum Foil Waste as Catalyst for Esterification of Waste Cooking Oil
Research Output | Dar Al-hikmah Library | IIUM Only

In this study, aluminum chloride hexahydrate (AlCl3.6 H2O) was derived from aluminum foil waste as a heterogeneous acid catalyst in the esterification of waste cooking oil. The parameters of catalyst loading (2–8 wt%), ultrasonic frequency (12–40 kHz), and reaction time (15–60 min) were optimized for maximum biodiesel yield production. Under

Manufacturing Strategies and Tribology of Tailored Tool Surface Topographies for Enhanced Lubrication in Metal Forming
Research Output | Dar Al-hikmah Library | IIUM Only

Lubricants are applied extensively in metal forming. Currently, methods to prevent wear are always emphasize the need for lubricants with ability to form boundary layers, chemically bonded to tool and workpiece surfaces. Tailored tool surface topography, as a kind of new engineered tool surfaces consisting of lubricant pockets on a hard tool materi

The Wettability Characteristics of Dlc Coating for Tribological Engineering Applications
Research Output | Dar Al-hikmah Library | IIUM Only

Hard coating deposited to tool steel surface can greatly improve wear resistance and reduce sticking. Since solid-liquid interactions are present in every lubricated tribological contact, the present study is aimed to understand the physical phenomena of contact interactions between the DLC coated surface and the liquid. In this study, double-layer

Research Output | Dar Al-hikmah Library | IIUM Only

End of life (EOL) care presents a number of legal and ethical challenges in all societies irrespective of their economic, cultural, or religious backgrounds. The issues range from attempts to prolong the lives of dying patients through highly advanced medical technologies, to efforts to terminate life prematurely through euthanasia and medically as

in-Situ Biofabrication of Silver Nanoparticles in Ceiba Pentandra Natural Fiber Using Entada Spiralis Extract with their Antibacterial and Catalytic Dye Reduction Properties
Research Output | Dar Al-hikmah Library | IIUM Only

It is believed of great interest to incorporate silver nanoparticles (Ag-NPs) into stable supported materials using biological methods to control the adverse properties of nanoscale particles. In this study, in-situ biofabrication of Ag-NPs using Entada spiralis (E. spiralis) aqueous extract in Ceiba pentandra (C. pentandra) fiber as supporting mat

Biosynthesized Silver Nanoparticles by Aqueous Stem Extract of Entada Spiralis and Screening of their Biomedical Activity
Research Output | Dar Al-hikmah Library | IIUM Only

Silver nanoparticles (Ag-NPs) have been established as antibacterial nanoparticles and have been innovatively developed to overcome the occurrence of antibiotic resistance in the environment. In this study, an environmentally friendly and easy method of the biosynthesis of Ag-NPs plants, mediated by aqueous extract stem extract of Entada spiralis (

Corporate Social Responsibility of Islamic Banks: Malaysian Practitioners’ Outlook
Research Output | Dar Al-hikmah Library | IIUM Only

Purpose – The purpose of this paper is to investigate Malaysian practitioners’ general perspective on corporate social responsibility (CSR) of Islamic banks and their views on having a special CSR framework. Design/methodology/approach – This study used semi-structured face-to-face interviews, which contained both qualitative and quantitative

finite-Element Modelling of Niti shape-Memory Wires for Morphing Aerofoils
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents the development and implementation of a user-defined material (UMAT) model for NiTi Shape-Memory Alloy (SMA) wires for use in LS-DYNA commercial explicit finite-element analysis software. The UMAT focusses on the Shape-Memory Effect (SME), which could be used for actuation of aerostructural components. The actuation of a fundame

The Translation and Adaptation of the Parent Proxy kid-Kiddokindlr Questionnaire on Quality of Life (Qos) for Primary school-Aged Children with Hearing Impairment
Research Output | Dar Al-hikmah Library | IIUM Only

The objectives of this paper are to translate and adapt the parent proxy Kid-KiddoKINDLRR questionnaire on Quality of Life (QoL) for children with hearing impairment into Malay language and to describe the translation techniques used, as well as the equivalence issues, with regards to morphology and semantics, encountered during the process. A comb
