In spite of that, this metal is a highly expensive material in the manufacture of low-cost appliances. In the present work, scrap gold, produced in jewellery as waste, is introduced as a low-cost resource of gold to be recycled. A gold electrode was fabricated by connecting the tablet shaped recycled gold with copper wire inserting into a polytetrafluoroethylene (PTFE) tube. The manufactured electrodes are easily renewable, modifiable with nanomaterials and show excellent electrochemical characteristics in presence of redox species. The CV (cyclic voltammetry), DPV (differential pulse voltammetry), and EIS (electrochemical impedance spectroscopic) analysis data also infer that the developed recycled gold-based electrodes would be suitable for the development of low-cost electrocatalytic sensors devices.</p> Mohammad Al Mamun, Yasmin Abdul Wahab, M.

Synthesis and crystal structure is briefly investigated. Their application in high temperature and high pressure as anti-friction and antiwear, and improve the anti-wear and extreme pressure properties have been described. The effect of various 1,3,4-thiadiazole additives on the tribological properties of base oils is studied. This paper aims to present an overview of the role of 1,3,4-thiadiazole and its derivative in improving the tribological properties of base oils.</p> NURUL FATIMAH ABDUL BASIR, YASMIN ABDUL WAHAB, MOHD RAFIE JOHAN, NADER GHAFFARI KHALIGH Copyright (c) 2022 Malaysian Catalysis-An International Journal https://ejournal.um.edu.my/index.php/MCIJ/article/view/38145 Fri, 21 Oct 2022 00:00:00 +0800 Recent Developments in Catalytic Reductive Etherifications https://ejournal.um.edu.my/index.php/MCIJ/article/view/38223 <p>Ether derivatives are versatile organic compounds and have been applied in various fields of academia and the chemical industry. Therefore, it is highly desirable to create procedures for their manufacture that are more efficient and sustainable. Catalytic reductive etherification with carbonyl moiety such as ketones/ aldehydes and carboxylic acid derivatives has recently been recognized as a possible tool among the several techniques reported for ether production. These procedures offer promising methods to selectively produce ethers with higher molecular structures, both symmetrical and asymmetrical. This Review provides an update on current developments in the field of catalytic reductive etherification, which synthesize ethers utilising an alcohol and an aldehyde substrate. Applications for organic synthesis and catalyst design are given special attention.</p> Lia Zaharani, Nader Ghaffari Khaligh Copyright (c) 2022 Malaysian Catalysis-An International Journal https://ejournal.um.edu.my/index.php/MCIJ/article/view/38223 Fri, 21 Oct 2022 00:00:00 +0800
