ABSTRACT:  This presentation describes my recent work  in developing small scale fluid devices, microfluidics, for energy applications and CO₂ sequestration. Microfluidics has emerged over the last two decades with applications in biomedical diagnostics, environmental monitoring, and life sciences research.

ABSTRACT:  Converting sunlight into chemical energy via solar thermal reforming of natural gas is an attractive route to increase the energy content of methane, consequently reducing both natural gas consumption and greenhouse gases emission. The upgraded ²solar² fuel can be used for direct power generation in gas turbines or as a feedstock for chemical industry.

ABSTRACT:  Diminishing resources are creating a global paradigm change towards more efficient, sustainable and cleaner use of energy. The conversion of chemical energy in heterogeneous catalysis is at the centre of this rapidly growing field of energy science. Since our understanding of the elementary processes constituting the reaction steps is still in its infancy, macro-scale concepts are likely to be challenged by emerging insights on the atomic scale.

ABSTRACT: Crystallization is important for pharmaceuticals, amino acids, and proteins. The first part of this seminar will discuss the crystallization of small-molecule organic chemicals such as pharmaceuticals and amino acids. The crystal size distribution (CSD) can affect the efficacy of drug products (such as the amount of drug reaching the lungs from a nasal spray) as well as the efficiency of downstream processes such as filtration and milling.

ABSTRACT:  Lithium sulfur (Li-S) batteries have attracted increasing attention because of their high theoretical capacity, natural abundance, low cost and environmental friendliness. Assuming Li₂S as the end product, the maximum specific capacity and energy from Li-S batteries are 1675 Ah kg⁻¹ and 2650 Wh kg⁻¹, respectively, significantly higher than those of state-of-the-art lithium ion batteries.
