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...

Hot Melt Extrusion: Identification and optimization of key excipients utilizing high-throughput screening methodology. By utilizing various tool kits available in the chemical engineering toolbox, a case study would be presented on formulation development in an accelerate timeframe for a marketed...

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...

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...
