Aquatic Toxicology Notes: Endothall by P. Chris Wilson, Jun Wu

“…It is also used as a defoliant and desiccant in some terrestrial situations (e.g., in potato, hops, cotton, clover, and alfalfa production). This 7-page fact sheet introduces users of endothall to the physical, chemical, environmental, and ecological properties of this herbicidal active ingredient relative to the aquatic environment. …”

Thermoelectric Characterization of Electronic Properties of GaMnAs Nanowires by Phillip M. Wu, Waldomiro Paschoal, Sandeep Kumar, Christian Borschel, Carsten Ronning, Carlo M. Canali, Lars Samuelson, Håkan Pettersson, Heiner Linke

“…We determine the carrier type (holes) and concentration and find a sharp increase of the thermopower below temperatures of 120 K that can be qualitatively described by a hopping conduction model. However, the unusually large thermopower suggests that additional mechanisms must be considered as well.…”
