Improving measurements of SF6 for the study of atmospheric transport and emissions [PDF]

open access: yes, 2011
Sulfur hexafluoride (SF6) is a potent greenhouse gas and useful atmospheric tracer. Measurements of SF6 on global and regional scales are necessary to estimate emissions and to verify or examine the performance of atmospheric transport models.

Controlled decomposition of SF6 by electrochemical reduction

open access: yesBeilstein Journal of Organic Chemistry, 2020
The electroreduction of SF6 is shown at ambient temperature in acetonitrile using an array of platinum microelectrodes to improve the electrical detection. Its half reduction potential occurs at −2.17 V vs Fc+/Fc.

Dynamics of fluctuations in a fluid below the onset of Rayleigh-B\'enard convection [PDF]

open access: yes, 2003
We present experimental data and their theoretical interpretation for the decay rates of temperature fluctuations in a thin layer of a fluid heated from below and confined between parallel horizontal plates.

Simulation of PD Optical Signal Mechanism Based on FCT Algorithm

open access: yesShanghai Jiaotong Daxue xuebao, 2020
The flux-corrected transport (FCT) algorithm is used to simulate the two-dimensional planar needle-plate structure of the positive streamer model and the partial discharge process of tip defects. The variations in electron density, net charge density and

Accelerator Testing of the General Antiparticle Spectrometer, a Novel Approach to Indirect Dark Matter Detection [PDF]

open access: yes, 2005
We report on recent accelerator testing of a prototype general antiparticle spectrometer (GAPS). GAPS is a novel approach for indirect dark matter searches that exploits the antideuterons produced in neutralino-neutralino annihilations.

Beef Steers and Enteric Methane: Reducing Emissions by Managing Forage Diet Fiber Content

open access: yesAnimals, 2023
Understanding the methane (CH4) emissions that are produced by enteric fermentation is one of the main problems to be solved for livestock, due to their GHG effects. These emissions are affected by the quantity and quality of their diets, thus, it is key

Laboratory simulation of the formation of an ionospheric depletion using Keda Space Plasma EXperiment (KSPEX)

open access: yesAIP Advances, 2017
In the work, the formation of an ionospheric depletion was simulated in a controlled laboratory plasma. The experiment was performed by releasing chemical substance sulfur hexafluoride (SF6) into the pure argon discharge plasma. Results indicate that the

The Decomposition Products of Sulfur Hexafluoride (SF6) with Metals Dissolved in Liquid Ammonia

open access: yesInorganics, 2017
Sulfur hexafluoride is a highly chemically inert gas with several important industrial applications. It is stable against fused alkali, oxygen and ammonia, even at several hundred degrees Celsius. In this work, the reactions between metals (Li–Cs, Sr, Ba,
