Modified AnoporeTM Hybrid Membranes for the Microfiltration of Cellulose Acid Hydrolysis Mixtures

Oct 18, 2011

Yong-Hong Zhao

Three classes of nonfouling substances, poly[poly(ethylene glycol) methyl ether methacrylate] (POEM), poly(sulfobetaine methacrylate) (PSBMA), and perfluoroalkyl tagged poly(ethylene glycol) surfactants (fPEG), were covalently tethered onto the surface of Anopore TM membranes (nominal pore size 0.2...

Cellobiose Hydrolysis Using Acid-Functionalized Nanoparticles

Oct 18, 2011

Leidy Peña

Mineral acids have been used effectively for the pretreatment of cellulosic biomass to improve sugar recovery and promote its conversion to ethanol; however, substantial capital investment is required to enable separation of the acid, and corrosion-resistant materials are necessary. Disposal and...

Membrane Filtration of Lignocellulosic Hydrolyzates: Comparison of Crossflow and Dead-End Microfiltration

Oct 18, 2011

Bhavin Bhayani

Depleting oil reserves have encouraged the development of technologies to harness the natural resources to sustain the energy needs. Renewable lignocellulosic biomasses have been focus of many studies but advances in the purification and recovering of the products from the product medium has been...

Acetic Acid Removal From the Hydrolysate Using Reactive Extraction In a Membrane Extractor/Reactor

Oct 18, 2011

Rahul Patil

Production of bioethanol from lignocellulosic biomass requires pretreatment of the biomass to hydrolyze hemicellulose, separate lignin and reduce cellulose crystallinity. During the pretreatment by dilute acid hydrolysis, several grams of acetic acid per liter of hydrolysate is generated. Acetic...

Cell Population Heterogeneity and Mass Transport Dynamics Modulate Tissue Regeneration Processes

Nov 9, 2010

Kyriacos Zygourakis

A better understanding of the complex interplay between cell population dynamics and mass transport is necessary for overcoming the barriers that have slowed down the development of bioartificial tissues. In a recent publication [1], we presented the development of a multi-scale computational model...
