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...

Catalytic study on lignin degradation and conversion into biofuels Wei Mu and Yulin Deng School of Chemical and Biomolecular Engineering and IPST at GT, Georgia Institute of Technology, Atlanta, Georgia 30332-0620 Author for correspondence (e-mail: yulin.deng@chbe.gatech.edu ) As an ideal...

I will describe my participation over the past few years in an effort to find fundamental mathematical laws in biology. I will discuss a theory for understanding the emergence of multi-scale, hierarchical structure in biology. I will describe how modular structure in proteins, genetics, and...

The first step in the conversion process of biomass to biofuels or hydrogen lies in picking an environmentally friendly solvent which is capable of breaking up the crystalline microstructure of cellulose. Once the cellulose is in suspension, enzymes (cellulases) are added to the reactor to...

The biological pretreatment of wood biomass for degrading lignin, a complex aromatic polymer, has received much attention as an environmentally safe or “green” process. Generally, enzymes isolated from naturally occurring fungi, or with enzymes produced by genetically engineered fungi have been...

Bio-Ethanol/water separation by fractional distillation becomes a popular industrial process to remove water from ethanol-water mixture. However, the mixture of 95.6wt% ethanol and 4.4 wt% water is an azeotrope and cannot be further purified by distillation. Alternatively, this can be achieved by...

Since biochar properties can vary widely depending on feedstock and processing conditions, making meaningful comparisons between biochar produced by different processes (pyrolysis, gasification, kiln carbonization) and at different locations can be difficult. Biochar characterization methods can...

When produced from waste lignocellulosic materials, hydrogen is one of the most promising options for a long-term, net-zero emission energy carrier. A major barrier to industrial scale production of bio-H 2 is its techno-economic feasibility. Advances in consolidated bioprocessing are required to...

The use of biomass as a source of energy has been studied extensively inrecent years, and special attention has been paid to biomass gasification. In this study, ASPEN Plus is used to conduct technoeconomic analysis of a large biomass gasification system. A biorefinery scenario consisting of 2,000...
