ABSTRACT: Mid-December 2014 is set to be the historical launch of the first commercial fuel-cell vehicle, heralding a transition from fossil-fueled vehicles to cleaner hydrogen-fed vehicles. Despite this significant milestone in making, there is an aggressive approach for further reduction in the cost of the polymer electrolyte fuel cell (PEFC) stacks while maintaining/ improving its electrochemical performance.
ABSTRACT: Advanced lithium ion battery electrodes experience large volume changes caused by concentration changes within the host particles during charging and discharging. Electrode failure, in the form of fracture or decrepitation, can occur as a result of repeated volume changes. In this presentation, we will provide an overview of our recent work on understanding the evolution of concentration, stress, and strain energy within a spherically- or cylindrically-shaped electrode element under various charging-discharging conditions.
ABSTRACT: Polymers and other materials that are used in contact with biological fluids such as blood are prone to protein adsorption and cell interactions. A protein layer quickly forms at the surface of the material and can influence the subsequent adhesion of platelets, leukocytes, other cells and microbes. For medical devices this can lead to numerous complications including coagulation, thrombosis (blood clotting) and infection, among others.
ABSTRACT: We propose a processing alternative for replacing the traditional and environmentally dangerous solvents (as monoethanolamine, diethanolamine) in the process of CO2 capture. We use a computer aided molecular design (CAMD) methodology for exploring the use of ionic liquids (ILs) as solvents for CO2 capture. The CAMD formulation is solved as a mixed-integer nonlinear programming (MINLP) problem, the objective is to obtain an optimal molecular structure of an ionic liquid for CO2 capture from a post-combustion (PC) gas stream (GS).
ABSTRACT: The rigidity of our skeleton is due to reinforcement with nano-sized minerals of biological apatite. Theories of skeletal apatite nucleation include initiation by the organic matrix (collagen and non-collagenous proteins), and increasing the phosphate concentration by hydrolysis of phosphoric acid monoesters. An enzyme that has been attributed to skeletal mineralization - tissue-nonspecific alkaline phosphatase (TNAP) - is known to increase inorganic phosphate concentration by catalyzing phosphoric acid monoester hydrolysis. However, the substrate for TNAP in
ABSTRACT: Nanotechnology offers highly customizable platforms for producing minimally invasive and programmable strategies to diagnose and treat cancer. Advances in this field have demonstrated that nanoparticles can enhance specificity of anti-cancer agents, respond to tumour-specific cues, and direct the visualization of biological targets in vivo.

ABSTRACT: The Acetone-Butanol-Ethanol (ABE) fermentation by anaerobic bacteria from the genus Clostridium was one of the first large-scale industrial bioprocesses, operating globally for the production of acetone during the first half of the 20th Century. Feedstock and product recovery costs prevented the ABE process from remaining profitable and acetone production was overtaken by the developing petroleum industry.

ABSTRACT: In this presentation we give an overview of recent applications in Process Systems Engineering of new discrete and continuous optimization techniques. We first provide a brief overview of logic-based optimization methods, emphasizing the theoretical relation of the continuous relaxations between mixed-integer programming and generalized disjunctive programming for nonconvex optimization problems.
ABSTRACT: Plastic foams, as engineering materials, are widely used in variety of industrial sectors and represent an extraordinary class of materials. Foaming in polymers involves delicate scientific mechanisms and unique morphology transformations. This work explores the influence of rheological properties on polymer foam development in non-pressurized systems.
ABSTRACT: Arguably, electric and hybrid electric vehicles are the new frontiers for lithium batteries. As a new market it is distinctly different from mass produced microelectronics, not only in the energy per battery unit but also in the power performance requirements. Especially the required charging rates during deceleration and emergency charging, as well as, the discharge rates during startup from standstill are exciting challenges.
