Rapid Deposition of Titania Nanoparticles for Dye Solar Cells

Oct 18, 2011
Rocco Panella
Dye-sensitized solar cells (DSSCs), while only having been designed about twenty years ago, are considered to be one of the most promising third-generation solar cell technologies among experts. One of the key features of DSSCs is a mesoporous, 10 micron layer of titania nanoparticles which acts as...

Comparison of Chemical and Biological Delignification of Cardboard

Oct 18, 2011
Estefania Isaza
Some processes aimed to biofuels production, use lignocellulosic wastes as feedstocks for fermentative conversion. If this is the case, pretreatment is required to make these resources fully digestible. Among a wide range of pretreatment options, this study focuses and compares oxidative-alkaline...

Realizing the Potential of Advanced Biofuels

Oct 18, 2011
Thomas Foust
Advanced biofuels or drop-in fuels is the terminology used to refer to hydrocarbon fuels that are direct replacements or supplements for existing gasoline, diesel and jet fuels currently refined from conventional petroleum feedstocks. Drop-in fuels from biomass will need to meet all of the refinery...

The Role of Acidic Catalyst Support On the Catalytic Upgrading of Bio-Oils

Oct 18, 2011
Sunya Boonyasuwat
Catalytic conversion of bio-oil vapor has attracted considerable interest as a promising pathway for upgrading. In this work, the reaction of anisole and guaiacol, phenolic model compounds commonly existing in bio-oils, were studied over an acidic silica-alumina catalyst and at varying space times...

Cellulase Inhibition by Pretreatment-Released Biomass Degradation Products

Oct 18, 2011
G. Peter van Walsum
The influence of pretreatment chemistry and the severity of dilute acid pretreatment on the subsequent enzymatic hydrolysis of soluble oligomer-derived and insoluble crystalline cellulose using a commercial enzyme preparation (Novozymes) was investigated. A dilute acid pretreatment was performed on...

Pyrolytic Pathways to Advanced Biofuels

Oct 18, 2011
R. C. Brown
Pyrolysis is the thermal conversion of carbonaceous materials in the absence of molecular oxygen to liquids, solids and gases. In the most general sense, pyrolysis can occur in an inert or reducing atmosphere or within a solvent (including water); it can occur at atmospheric or elevated pressure;...

A Future Energy Supply Based on Liquid Organic Hydrogen Carriers (LOHC)

Oct 18, 2011
Daniel Teichmann
This lecture describes a concept for the establishment of a competitive energy distribution network based on Liquid Organic Hydrogen Carrier (LOHC) compounds. These compounds are characterized by the fact that they can be loaded and un-loaded with considerable amounts of hydrogen in a cyclic...

Lignin Depolymerization and Deoxygenation In Ionic Liquids

Oct 18, 2011
Blair J. Cox
Lignin, an amorphous aromatic biopolymer that comprises up to 30% of plant matter, was dissolved and depolymerized in ionic liquids under acidic conditions. The acidic ionic liquid 1-methylimidazolium chloride (HMIMCl) acts as a combination solvent and catalyst that facilitates degradation of...
