21. Assessment of human swallowing using in-vivo and in-vitro approaches
Abstract : Texture modification is the most vital strategy to manage dysphagia: a condition in which food and beverages are difficult to swallow. Typically thickeners in the form of starch or gums are added to the food to increase the viscosity and thereby reduce the speed of bolus flow. READ MORE

22. Mechanisms of Biopolymer Solvation: Development of a two-component ionic liquid solvent system
Abstract : Ionic liquids are of potential interest in the processing of lignocellulosic biomass, and/or its components, for the purpose of producing renewable and value-added biomaterials. An understanding of how solvation can be achieved and the way in which the feedstock biopolymers are affected, however, needs to be gained prior to a viable implementation. READ MORE

23. Direct conversion of methane-to-methanol: transition-metal dimer sites in small-pore zeolites: First-principles calculations and microkinetic modeling
Abstract : Direct conversion of methane to methanol is a highly desired reaction. Partially oxidizing methane into a liquid fuel at ambient temperature and pressure would enable utilization of natural gas and biogas to a much larger extent than what is possible today. READ MORE

24. Aging effects on commercial lean NOx trap catalysts
Abstract : As a countermeasure to global warming, vehicles with low carbon emissions are being investigated by promoting lean-burn engines and high combustion efficiencies. However, one limitation to the increasing use of these engines is the need to develop corresponding catalytic systems for controlling the nitrogen oxide (NOx) emissions in their lean exhaust.

25. Novel catalysts development for NOx reduction from H2 combustion engines
Abstract : Hydrogen, as a clean energy carrier, burns without producing any carbon emissions. Hydrogen internal combustion engines (H2-ICE) are considered an alternative for the transition from conventional fossil-fuel vehicles. READ MORE
