Sustainability by designing polymer membranes for water reuse, seawater desalination and osmotic power generation
Clean water, clean energy, global warming and affordable healthcare are four major concerns globally resulting from clean water shortages, high fluctuations of oil prices, climate changes and high costs of healthcare. Clean water and public health are also highly related, while clean energy is essential for sustainable prosperity.
Among many potential solutions, advances in membrane technology are one of the most direct, effective and feasible approaches to solve these sophisticated issues. Membrane technology is a fully integrated science and engineering which consists of materials science and engineering, chemistry and chemical engineering, separation and purification phenomena, environmental science and sustainability, statistical mechanics-based molecular simulation, process and product design.
In this presentation, we will introduce our efforts on membrane development for water reuse, seawater desalination and osmotic power generation. In the beginning, we will introduce the basic science of hollow fiber fabrication, then talk about the ultrafiltration membrane development as a pre-treatment for seawater RO. After that, focuses will be shifted to nano-filtration, forward osmosis and osmotic power generation. Various material and fabrication strategies to enhance membrane performance will be discussed.

Photocatalytic Carbon Dioxide Reduction to Fuels in Monolith Reactor
Catastrophic weather changes are linked to climate change. Climate change is associated with excess amount of carbon dioxide (CO2) and methane (CH4) from various sources including palm oil mills, power plants and vehicles. Hence, photocatalytic reduction of CO2 to fuels is one of the feasible solutions to alleviate the effect of climate change. The synthesis of heterogeneous photocatalyst combines the unique properties of semiconductor and metal oxides to synergize the effect between charge recombination rate and redox potentials. However, the surface properties of the catalyst and coke resistant ability should be improved to obtain high yield of fuel. From the characterization results of TiO2 nanoparticles modified with metal, the CO2 adsorption, band gap of photocatalyst, and electrochemistry are crucial for obtaining high fuel selectivity. Since CO2 has high acidity, a photocatalyst with basic surface is essential for better adsorption between CO2 and the catalytic surface. Apparently, rate of recombination between hole and electron is a major limitation for semiconductor material. The use of co-catalysts for reducing the rate of electron-hole recombination could improve the performance of the catalyst. The use of monolith reactor improves the efficiency of the photocatalytic system.

Renewable Energy and Role of Hydrogen as a Future Fuel
AbstractDue to world population growth, growing industrial development, improvements in living standards, emerging technologies (such as electric vehicles) and the growth in domestic and industrial use of modern equipment, the current growing trend in electricity demand and consumption will continue long into the future. The management of electrical energy supply to meet the growing demand without contributing more to the green-house gas problem is a major task. To reduce green-house gases, more and more renewable sources of electrical energy are being added to networks. However, these new sources of supplies can be intermittent and variable. Wind for example, is avaluable source of green energy but its availability is very variable. Solar energy is available during the day time subjected to sun shine but it is not available during the night. Usually peak demand of electricity for industrial customers is during the day time and the peak demand for domestic customers is during early evenings. Growth and sustainability of future renewable energies therefore requires the management of electricity networks using smart grid technologies. It also requires options to store energy and regenerate during demand periods. On small scale, options are required to have self-contained integrated systems to store energy. Hydrogen in this context is considered to be the clean fuel of the future which does not contribute to greenhouse gases. Moreover hydrogen has been recognised as a possible energy storage medium. Excess electricity from wind and solar could be converted to hydrogen by electrolysis. Depending on the application, hydrogen could be stored using various techniques. In this lecture the role of hydrogen in the context of renewable energy is explained and the methods of hydrogen storage options are discussed. Properties of Hydrogen as a fuel is further explained and advantages and disadvantages of hydrogen are also discussed. Research undertaken into hydrogen storage systems, combustion and safety aspects of hydrogen are further highlighted.
