The effect of trophic exposure to pyrolitic polycyclic aromatic hydrocarbons (PAH) on aerobic metabolism of zebrafish Danio rerio was investigated. There were no significant differences in standard metabolic rate (SMR), active metabolic rate (AMR) or aerobic metabolic scope (AS) at any sublethal concentration of PAH in the diet of adult or juvenile fish. This suggests that under these experimen...

Magnetotransport measurements performed on several well-characterized highly oriented pyrolitic graphite and single crystalline Kish graphite samples reveal a reentrant metallic behavior in the basal-plane resistance at high magnetic fields, when only the lowest Landau levels are occupied. The results suggest that the quantum Hall effect and Landau-level-quantization-induced superconducting cor...

1. INTRODUCTION The application of laser forward transfer techniques has steadily grown since the first reports of patterned copper deposition by Bohandy, et al. 20 years ago (Bohandy, 1986). These general techniques employ a pulsed laser to locally transfer material from a source film onto a substrate in close proximity or in contact with the film. The source is typically a coated laser-transp...

Polycyclic aromatic hydrocarbons (PAHs) are of high concern to public health due their carcinogenic and mutagenic properties. Here, we present the first comprehensive quantitative analysis sources, potential source regions according sectors source-related human risks multi-year atmospheric measurements PAHs in Canadian Great Lakes Basin (GLB). The highest PAH concentrations were observed at a r...

The self-assembly properties of a series of functionalized regioregular oligo(3-alkylthiophenes) were investigated by using scanning tunneling microscopy (STM) at the liquid-solid interface under ambient conditions. The characteristics of the 2-D crystals formed on the (0001) plane of highly ordered pyrolitic graphite (HOPG) strongly depend on the length of the π-conjugated oligomer backbone, o...
