Two procedures were developed to fit interatomic potentials of the embeddedatom method (EAM) form and applied to determine a potential which describes crystalline and liquid iron. While both procedures use perfect crystal and crystal defect data, the first procedure also employs the first-principles forces in a model liquid and the second procedure uses experimental liquid structure factor data...
Gels with the ability to immobilize a liquid phase are structures of three-dimensional network. These types of gels consist of two parts, gelling agent (network forming) and liquid solvent phase (hydrophilic or hydrophobic). However, depending on the polarity of the liquid immobilized within the networked structure, gels may be termed either as hydro gels (polar solvent-water) or organogels (or...
We describe a phenomenon of ribbon-to-fiber transformation observed in the process of spinning of single wall carbon nanotubes dispersed in polymer solutions. In the process of spinning, a gel-like ribbon comprised of nanotube bundles bound by polymer is withdrawn from a solvent bath. We show that upon crossing the liquid-air interface, the ribbon may either retain its flat shape or fold into a...
Leonard, C. Gomez (U.S. Army Biological Laboratories, Fort Detrick, Frederick, Md.), D. K. Mattheis, M. J. Mattheis, and R. D. Housewright. Transformation to prototrophy and polyglutamic acid synthesis in Bacillus licheniformis. J. Bacteriol. 88:220-225. 1964.-Growth conditions necessary for transformation to prototrophy of 14 auxotrophs of Bacillus licheniformis were studied. The unexpected fi...
The sorptivity S quantifies the effect of capillarity on liquid movement in a porous material. For liquid infiltration into an initially dry material, S is a parameter that is contingent on both liquid and material properties as well as the maximum liquid content behind the infiltrating front, θm. In prior work, Culligan et al. (2005) used scaling analyses to derive a dimensionless, intrinsic s...
Citalopram (CTR) is a worldwide highly consumed antidepressant which has demonstrated incomplete removal by conventional wastewater treatment. Despite its global ubiquitous presence in different environmental compartments, little is known about its behaviour and transformation processes during wastewater treatment. The present study aims to expand the knowledge on fate and transformation of CTR...
Aflatoxin B(1) (AFB(1)) is commonly found in cereals and animal feeds and causes a significant threat to the food industry and animal production. Several microbial isolates with high AFB(1) transformation ability have been identified in our previous studies. The aim of this research was to characterize one of those isolates, Myxococcus fulvus ANSM068, and to explore its biotransformation mechan...
Explosives contamination in surface or groundwater used for the irrigation of food crops and phytoremediation of explosives-contaminated soil or water using plant-assisted biodegradation have brought about concerns as to the fate of explosives in plants. Liquid scintillation counting, high-performance liquid chromatography, and gel permeation chromatography were utilized to characterize explosi...
