Field data and 222Rn activities from the Altona well field. 222Rn, the most stable isotope of radon, was tested for during well extraction experiments. Tracers were also tracked to monitor the well. Data include 222Rn activities and complimentary geochemical data for multiple field experiments as part of an EGS project.

This is USDA-ARS data from the publication: "Performance of a cotton gin machine that removes plastic contamination from seed cotton." The study was conducted during the Fall of 2020 with continued data analysis thru September 2021. Plastic contamination is the most pressing issue for the U.S. cotton industry today. Due to this problem, U.S. cotton has lost the 7 cents per pound premium it brought on international cotton markets. Plastic contaminants are often introduced prior to ginning, but cotton gin machinery can tear and shred the plastics so that they become more difficult to remove. A cotton gin machine developed and used to combat the plastic contamination problem in Chinese cotton was tested to compare its performance at removing typical plastics found in U.S. cotton to that of conventional cotton gin seed cotton cleaners.

Batch tests of cross-linked lithium and manganese imprinted polymers of variable composition to assess their ability to extract lithium and manganese from synthetic brines at T=45 deg C .

This file contains silica precipitation and lithium sorption data from the project. The silica removal data is corrected from the previous submission. The previous submission did not take into account the limit of detection of the ICP-MS procedure.

The data provided in this upload is summary data from its Demonstration Plant operation at the geothermal power production plants in the Imperial Valley. The data provided is averaged data for the Elmore Plant and the Featherstone Plant. See average brine composition tab for submitted compositional data. Included is both temperature and analytical data (ICP_OES). Provided is the feed to the Simbol Process, post brine treatment and post lithium extraction.

A paper describing natural gas reserves in the eastern United States, how much may be obtainable, and how production would work. From the paper: "A project has been Initiated by the Energy Research and Development Administration {ERDA) to characterize gas-bearing shale formations and develop improved gas-extraction technology for these lowpenneabl 11 ty "tight" reservol rs. The Eastern Devonian Shales are very prominent In this assessement, since they underlie a large section of the eastern and central portions of the United States. There Is considerable uncertainty In the magnitude of the hydrocarbon resource base since estimates range as high as 460,000 TCF {gas equivalents) In the Appalachian Basin alone; however, a recent estimate places the gas In place at 2,400 TCF. If only 10 percent of this latter figure were recovered, this would be enough natural gas to supply the eastern United States for 30 years at the current rate of consumption. Obviously, the potential payoff from the Eastern Shale is much greater If technology can be developed to increase the rate and amount of natural gas recovery. The primary reason why the natural gas has not been more fully exploited is that the wells that have been completed normally have low productivities, I.e., they produce at an average rate of 50,000 scf per day. By using advanced fracturing and stimulation methods, this rate may be increased two to four times. Fracturing results have been mixed since many new techniques have been tried. Massive Hydraulic Fracturing (MHF), foam, gas, dendrltic, and high yield explosives have already been tested with varying degrees of success or failure."
