Effect of AFEX Pretreatment Degradation Products On Enzymatic Hydrolysis and Microbial Fermentation by Saccharomyces Cerevisiae 424A(LNH-ST)

Oct 16, 2011

Venkatesh Balan

Several degradation products are formed or released during AFEX pretreatment process, which can be divided into five groups: 1) carbohydrates, 2) aliphatic acids, 3) nitrogenous compounds, 4) furans, 5) aromatic compounds. Some of these degradation products are expected to be inhibitory to...

HycycleS: Materials and Components for Hydrogen Production by Sulphur Based Thermochemical Cycles - Summary of Key Results From the European Collaborative Project

Oct 16, 2011

Rachael H. Elder

HycycleS is a European Framework 7 project focussing on the decomposition of sulphuric acid, a key step in the Hybrid Sulphur and Sulphur Iodine thermochemical cycles. The final aim is to bring thermochemical water splitting closer to realisation by improving the efficiency, stability,...

Mechanism of Li Adsorption On Carbon Nanotube-Fullerene Hybrid System: A First-Principles Study

Oct 16, 2011

Seung Soon Jang

The lithium (Li) adsorption mechanism on the metallic (5,5) single wall carbon nanotube (SWCNT)-fullerene (C 60 ) hybrid material system is investigated using first-principles method. It is found that the Li adsorption energy (-2.649 eV) on the CNT-C 60 hybrid system is lower than that on the...

Low Temperature Gasification of Impregnated Biomass Feedstock

Oct 16, 2011

Foster Agblevor

Hybrid poplar biomass feedstocks were impregnated with catalysts and gasified at three different temperatures in a bubbling fluidized bed reactor. The impregnated biomass were gasified in a nitrogen atmosphere at 400 o C, 600 o C, and 800 o C. The gas yield increased with increasing temperature as...

Novel Quaternary Ammonium Ionic Liquid Electrolyte for Stable, High Capacity Si Nanowire Based Li-Ion Battery

Oct 16, 2011

Vidhya Chakrapani

In recent years, there has been interest in silicon nanowires as an anode for Li-ion battery because of its large gravimetric capacity of 4200 mAh/g. 1D nanostructure are essential because they permit radial strain relaxation of mechanical stress which occurs due to the volumetric expansion (>...

Additionally, solution processing of semiconductor nanocrystals (NCs) provides a low-cost, scalable technique for the fabrication of third-generation...

Modelling Simultaneous Saccharification and Fermentation of Microcrystalline Cellulose Using Computational Fluid Dynamics

Oct 16, 2011

Josebus M. van Zyl

Cellulose found in almost all plant cell wall, making it one of the most abundant renewable and sustainable natural resource on the Earth’s surface. Cellulosic ethanol is receiving increasing attention as a viable alternative to the commonly used fossil fuel, petrol. Cellulosic ethanol is a second-...

Liquid-Liquid Equilibrium Compositions for the Iodine-HI-Water System of the Sulfur-Iodine Cycle At Elevated Temperatures and Pressures

Oct 16, 2011

Adam S. Klett

Liquid-liquid equilibrium (LLE) phase behavior was investigated for the ternary system iodine-hydroiodic acid-water (I 2 -HI-H 2 O) at the elevated temperatures and pressures of interest for the reactive distillation column of the Sulfur-Iodine Cycle. A continuous-flow apparatus, with wetted parts...

Sustainability of Biomass Crop Production

Oct 16, 2011

Shijie Liu

Woody biomass is renewable only if sustainable production is imposed. How to evaluate the benefit of different biomass crop species on a sustainability scale is a difficult task. Site dependence and regional diversity are the most important factors, while biomass productivity determines the...
