BOREAS RSS-17 Dielectric Constant Profile Measurements
The BOREAS RSS-17 team acquired and analyzed imaging radar data from the ESA's ERS-1 over a complete annual cycle at the BOREAS sites in Canada in 1994 to detect shifts in radar backscatter related to varying environmental conditions. This data set consists of dielectric constant profile measurements from selected trees at various BOREAS flux tower sites. The relative dielectric constant was measured at C-band (frequency = 5 GHz) as a function of depth into the trunk of three trees at each site. Measurements were made during April 1994 with an Applied Microwave Corporation field PDP fitted with a 0.358-cm (0.141-inch) diameter coaxial probe tip.
Soil Matric Potential, Dielectric, and Physical Properties, Arctic Alaska, 2018
This dataset provides lab-measured soil properties, including soil water matric potential, soil dielectric properties, soil electrical conductivity, corresponding soil moisture. The dataset also includes the basic soil physical properties such as soil organic matter, bulk density, porosity, fiber content, root biomass, and mineral texture. Soil samples were collected from August 21 to August 27, 2018, from the surface to permafrost table in soil pits at nine sites along the Dalton Highway in northern and central regions of Alaska. Permittivity and soil electrical conductivity measurements were conducted using METER TEROS 12 probes. Soil moisture measurements were made with a TEROS 21 probe. The measurements were conducted in the lab over the span of three years. The purpose of soil collection and lab measurements was to develop an integrated framework that relates the hydrological properties to dielectric properties of permafrost active layer soil in support of the NASA Arctic and Boreal Vulnerability Experiment (ABoVE) Airborne Campaign.

Data from: Enhancement on the electrochemical properties of commercial coconut shell-based activated carbon by H2O dielectric barrier discharge plasma
Commercial coconut shell-based activated carbon (CSAC) has low specific capacitance and specific capacitance retention owing to its undeveloped pore structure and low proportion of heteroatoms. In this study, dielectric barrier discharge (DBD) plasma was used to enhance the specific capacitance and rate capability of CSAC. H2O was used as excited medium to introduce oxygen functional groups. The physicochemical properties of CSAC and CSAC modified by H2O plasma (HCSAC) were revealed by automated surface area and pore size analysis, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy (Raman). Electrochemical workstation was applied to investigate the electrochemical properties of CSAC and HCSAC. Obtained results showed that plasma modification improved the specific capacitance of CSAC by 64.8% (current density, 1 A g-1; electrolyte, 6 M KOH solution) within 100 seconds. This result is ascribed to the oxygen functional groups introduced to the surface of CSAC. It can also improve hydrophilicity and wettability of the carbon surface leading to an increase from 76.7% to 84.6% in specific capacitance retention. Furthermore, H2O plasma modification can introduce oxygen functional groups without destroying the initial pore structures of CSAC. In summary, we provide a simple, fast, environment-friendly modification method to enhance the electrochemical properties of CSAC.

Analysed data for poster presentation "Dielectric barrier discharge plasma reduction of iron oxides"
<p>Native surface oxides, which usually contaminate metals in ambient atmosphere, limit the performance in industrial applications like coating or welding. Different deoxidation techniques were developed to remove such oxide layers. Promising results were obtained for dielectic barrier discharge (DBD) hydrogen plasmas in deoxidation of copper at 20 °C and 100 – 1000 hPa. In this study, we report the application of a DBD plasma for deoxidation of natively oxidized iron surfaces in an Ar/H2 atmosphere at 100 and 1000 hPa. Plasma treatments were performed at a discharge voltage of 10 kV and a frequency of 8.8 kHz at room temperature (RT) as well as in the combination with heating<br> </p>
