Cofermentation of glucose, xylose, and arabinose is critical for complete bioconversion of lignocellulosic biomass, such as agricultural residues and herbaceous energy crops, to ethanol. We have previously developed a plasmid-bearing strain of Zymomonas mobilis (206C[pZB301]) capable of cofermenting glucose, xylose, and arabinose to ethanol. To enhance its… (More)
Cofermentation of xylose and arabinose, in addition to glucose, is critical for complete bioconversion of lignocellulosic biomass, such as agricultural residues and herbaceous energy crops, to ethanol. A factorial design experiment was used to evaluate the cofermentation of glucose, xylose, and arabinose with mixed cultures of two genetically engineered… (More)
Shot noise encodes additional information not directly inferable from simple electronic transport measurements. Previous measurements in atomic-scale metal junctions at cryogenic temperatures have shown suppression of the shot noise at particular conductance values. This suppression demonstrates that transport in these structures proceeds via discrete… (More)
Subpicosecond laser pulses at power levels in excess of 1 TW were channeled through hollow microcapillary tubes by use of a combination of grazing-incidence dielectric and plasma-wall reflection mechanisms. Maximum input and output intensities were 10(17) and 10(16) W/cm(2) through 50-microm radius by 3-cm-long glass microcapillary tubes with as few as two… (More)
Archival tags (ATs) were deployed on 161 bigeye tuna (Thunnus obesus) caught and released in the western Pacific Ocean within the Australian Fishing Zone in the years 1999-2001 as part of an investigation into the movements and habitat preferences of this species. Seventeen fish have been recaptured to date, from which data were retrieved from 14 ATs. Time… (More)
Alkyl cyanoacrylates have long been used for the synthesis of colloidal nanoparticles. In the involved polymerization reaction, hydroxyl ions derived from dissociation of water have been used as an initiator. In the current research, an animal protein, bovine serum albumin (BSA) molecules were utilized as initiator for the polymerization. Following this… (More)
A 392 nm GaInN-based UV light emitter has been demonstrated by homoepitaxial growth technique aiming to improve quantum efficiency by crystalline perfection of the heterostructures on naturally stable semipolar (11–22) bulk GaN.
