Professor Stow is a leading sedimentologist, geologist and oceanographer of international standing with an extensive record of scientific publications, including over 200 scientific papers and reports, numerous books and edited volumes. He specialises in the deep sea and on deep-sea deposits now thrown up onto land. In pursuing this scientific quest he has sailed on all the world's major oceans, visited or worked in more than 50 countries and lectured extensively throughout the world. He has worked in and with the oil industry, particularly in their ongoing quest for deep-sea oil and gas and on new and tight reservoir targets; led a major international mission for scientific drilling into the deep Indian Ocean seafloor; and is currently co-chief scientist for IODP Leg 339 on Mediterranean Outflow research. He also maintains strong interest in the field of geoscience and development, with recent visits to Indian Kashmir, Assam and Sri Lanka, concerning hazard mitigation, geoscience education and marine management. His enthusiasm for the popularisation of ocean and earth sciences is expressed through lectures, writing and broadcast, including his recent books Oceans: An Illustrated Reference (2004) and Vanished Ocean (OUP, 2010). He is currently Director of Research and Professor of Petroleum Geoscience at the Institute of Petroleum Engineering, Heriot Watt University, and Director of the Edinburgh Collaborative of Subsurface Science and Engineering (ECOSSE).

Professor Dr Ahmad Zuhairi Abdullah is currently the Deputy Dean (Research, Postgraduate & Network) at School of Chemical Engineering, Universiti Sains Malaysia. He received his PhD from Universiti Sains Malaysia in PhD (2004) in the field of chemical engineering. His research works mostly encompass the use of novel functionalized nanoporous materials as catalysts in oleochemical conversions, waste treatment, green technology and production of renewable energy sources. He is among the pioneer researchers in the world to focus on the use of ultrasound to accelerate heterogeneous catalytic processes. He is the recipient of several innovation and publication awards based on his research works. His research expertise is often sought after for the assessment of Environmental Impact Assessment (EIA) reports on proposed strategic commercial projects such as oil refinery, petrochemical complex, sanitary landfill, smelting plant, used acid lead battery, paper mill etc. Various industrial problems have been successfully solved through his consultancy projects. He has been involved in the propagation of science and technology through more than 200 refereed publications in journals and book chapters mainly as the main author, and also involves as a technical committee member to nearly 100 international scientific conferences held across the globe. Many invitations on various roles have also been received to share his research experience with government officers, research scientists, junior researchers and school children. The objectives of the events vary from the latest development in nanoporous materials research, critical research skills, understanding science, promotion of sustainability, community awareness, carrier development to the understanding of policy and regulatory aspects. He is an academic external assessor to UniMAP and UniKL-MICET for their undergraduate and doctoral program, respectively. He also acts as an article reviewer to more than 100 different leading international journals in his area of expertise. In addition, he is an evaluator to research proposals received from the university, local ministries as well as international scientific associations in the USA, Oman, Qatar and Chile. He is one of the recipients of the Top Research Scientist Malaysia 2014 award. His h-index (Scopus) currently stands at 39..
Malaysian Perspective on Biodiesel Blends as
Renewable Fuel Sources for the Future:
Challenges Towards Sustainability of the
Abstract:Biodiesel is the most potential substitute for fossil fuel so far for its renewability, production rate and fulfillment of required fuel specifications. There are some technical issues with regards to the green features of the biodiesel production process especially the quality of feedstock, huge amount of wastewater and overproduction of glycerol. Biodiesel often require special additives or fuel heating systems to operate in colder climates. It may also cause some rubber seals and gaskets to fail. It also degrades some hoses, glues and plastics with prolonged exposure. Biodiesel can dissolve sediments in diesel fuel tanks and clog fuel filters. Fully converted monoalkyl esters are the major requirement in quality biodiesel. Unconverted triglicerides could polymerize and eventually build up in the fuel lines. Diesel engine normally has a higher oxide of nitrogen (NOx) emission profile. Producing biodiesel which consistently meets ASTM D6751-19 or EN 14214:2008 is not easily achieved. Biodiesel should not be stored longer than 6 months. If it is necessary, the acid value should be monitored and additive should be considered. The condensed water in the fuel tank can also support the growth of bacteria and mold. In terms of implementation of biodiesel programs, weak domestic demand and uncompetitive export tax structure are among the factors that can hold back the success of the biodiesel programs. Despite several biodiesel programs introduced on B5, B7, B10 and more recently B20, the success of its implementation is rather limited due to engine technical compatibility, its relatively high price and unfavorable international policy. Besides, the surplus of glycerol as a by-product of biodiesel industry in the market is a challenging situation as it is not considered a waste material.
