Propyl-sulfonic acid functionalized (PS) nanoparticles with various levels of functionalization were synthesized, characterized and evaluated as catalysts for pretreatment of corn stover. The degree of functionalization was measured as a function of the hydronium ion concentration, the total...

Understanding fluid flow through porous media is important in many fields of science and engineering. Some of these fields are ground water flow, production of petroleum fluids, CO 2 sequestration, air filtration, fuel cells, breathing etc. This paper describes a three dimensional lattice Botlzmann...

A recently-developed lubrication blending model identified formulation-dependent parameters for lubrication sensitivity, β, and lubrication rate constant, γ. The original study examined binary mixtures of common tableting excipients. Therefore, there is a need to determine if the lubrication model...

Control of the flow properties of powders during one or more unit operations of a manufacturing process is an essential part of ensuring that the process is well-controlled. It is commonplace to incorporate flow-modifying agents to match the flow properties of the powder to those required by the...

In the context of a desirable ‘carbon neutral’ energy economy, among the most promising solutions for replacing today’s GHG emitting vehicles is the use of hydrogen as an energy carrier. In the pathway towards a future infrastructure based on renewable energy sources, a medium term step would rely...

Stimulated by initiatives such as PAT and QbD, the pharmaceutical industry has been focusing on the development of innovative, efficient manufacturing methods. The concept of 'mini-manufacturing' of drugs, as opposed to mass production of drugs, has shown promise in this area. We describe one such...

The water gas shift (WGS) reaction is the upgrading stage in the cycles of hydrogen production by, for example, steam reforming of light hydrocarbons from fossil or renewable sources. This reaction limited by thermodynamics often carried out in industry to convert CO, producing more hydrogen. A WGS...

Continuous manufacturing of solid pharmaceutical products has been an area of much research in the past few years. Most efforts have focused in characterizing the bulk properties and efficiency of continuous powder mixers as a function of operational and design parameters. The present study...
