Currently, the complexity and scale dependency of land-use decisions and their impacts are not understood, defined, or described with adequate clarity to enable policy makers to develop strategies to ensure a sustainable bioenergy future with acceptable environmental and socioeconomic consequences...

Enzymatic Bioprocessing of Cellulose in N-Methyl Morpholine Oxide/Water

Nov 9, 2009
John Collier
To enzymatically convert biomass to biorefinery feedstock, biofuels, or hydrogen an environmentally friendly solvent or process is needed to disrupt the microstructure of lignocellulosics. In multi-stage processes, solvents are being used as pretreatments by dissolving cellulose and precipitation...

Optofluidic SERS Devices for Biomolecular Detection

Nov 9, 2009
Yun Suk Huh
Recently, Surface-enhanced Raman scattering (SERS) has attracted great attention because of its high sensitivity, label-free detection, and low detection limit. Additionally, it provides a specific fingerprint spectrum of multiplex samples with narrow band width. Because of these advantages, a...

Advanced Biofuels - The Path Forward

Nov 8, 2009
W. Densmore Hunter
Oil prices go up and they come down and our ability to forecast them with any real confidence has not been particularly good. A year ago when oil prices were at record highs and global economies were booming, the case for biofuels seemed clear. The path forward is cloudier today. Are we facing a...

Application of QbD Principles to Analytical Methods

Nov 8, 2009
Jackson Pellett
The same QbD Principles applied to the design of manufacturing processes are applicable to the design of analytical methodology. QbD elements such as understanding the science behind the methods, and improving method reliability by identifying and controlling sources of variability are key. This...

Update on QbD Implementation: An FDA Perspective

Nov 8, 2009
Christine Moore
Quality by Design (QbD) is a science and risk based approach for pharmaceutical process development and manufacturing that begins with first defining clinically relevant product attributes and then designing and implementing a process to consistently deliver quality product. Some key aspects of QbD...
