Tracer Testing at Dixie Valley, Nevada, Using 2-naphthalene Sulfonate and 2,7-naphthalene Disulfonate

The decay kinetics of the candidate tracers 2naphthalene sulfonate and 2,7-naphthalene disulfonate was studied under laboratory conditions that simulate a hydrothermal environment, with neither compound exhibiting any decay after one week at 330C. These data indicate that these compounds are more thermally stable than any of the previously studied polyaromatic sulfonates. Both of the tracer can...

Tracer Testing at Dixie Valley, Nevada Using 1-naphthalene Sulfonate and 2,6-naphthalene Disulfonate

The decay kinetics of the candidate tracers 1naphthalene sulfonate and 2,6-naphthalene disulfonate was studied under laboratory conditions that simulate a hydrothermal environment. Neither of the naphthalene sulfonates exhibited any thermal decay after one week at 330C, indicating that they are suitable for use in geothermal settings having temperatures of 330C or hotter. Both tracers were succ...

Avoidance of low doses of naphthalene by Collembola.

The introduction of behavioural aspects of soil animals in ecological risk assessment would allow us to better assess soil quality, all the more if a range of animal populations are considered. We compared the avoidance behaviour of several strains of springtails (Arthropoda: Collembola) obtained from different soils. Naphthalene, a polycyclic aromatic hydrocarbon (PAH), widely represented in s...

Diamond-Like Carbon Nanofoam from Low-Temperature Hydrothermal Carbonization of a Sucrose/Naphthalene Precursor Solution

Unusual structure of low-density carbon nanofoam, different from the commonly observed micropearl morphology, was obtained by hydrothermal carbonization (HTC) of a sucrose solution where a specific small amount of naphthalene had been added. Helium-ion microscopy (HIM) was used to obtain images of the foam yielding micron-sized, but non-spherical particles as structural units with a smooth foam...
