Reaching high ethanol titers after the fermentation step is crucial in cellulosic ethanol production in order to make the process cost competitive and commercially available. To achieve this, a high amount of water insoluble solids (WIS), i.e. lignocellulose fibers, is needed in the hydrolysis step...

Long-acting controlled release formulations address the top causes of non-compliance, a problem responsible for 10% of hospitalizations and over $100 billion in avoidable annual medical expenses. These formulation are also among the most difficult and costly formulations to design and produce...

The photochemical reduction of CO 2 in the presence of H 2 O to form CO, CH 4 and other light gases with industrial value is an interesting approach for dealing with CO 2 emissions. This approach can generate tangible revenue to help offset carbon capture and storage costs by generating a product...

This study conducted quantitative kinetic modeling and in-situ and temporally resolved measurements of adsorption, desorption, and re-adsorption of a commercial endoglucanase in lignocellulosic suspensions. The study defined a cellulase adsorption and desorption competition parameter, a pseudo rate...

C-H Activating Carboxylation of Terminal Alkynes with CO 2 and Its Application in Synthesis Yugen Zhang, Dingyi Yu, Siti Nurhanna Riduan, and Jackie Y. Ying Institute of Bioengineering and Nanotechnology 31 Biopolis Way, The Nanos, Singapore 138669, Singapore E-mail: ygzhang@ibn.a-star.edu.sg...

Ceramic proppant was imaged using x-ray computed microtomography (microCT) in three different geometries: bulk proppant, multilayer proppant pack between Berea walls, and single-layer proppant between shale walls. In all cases, the proppant packs were exposed to a range of confining stresses that...

With large proven global coal reserves, it is highly likely that combustion of coal and coal-derived products will remain part of the global energy future. Compared to other fossil fuels, coal-based power yields the highest CO 2 output per energy unit, indicating the critical need for some form of...

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...

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...
