Gaps in Knowledge Relevant to the “Guidelines for Limiting Exposure to Time-Varying Electric and Magnetic Fields (1 Hz–100 kHz)”
(Peer reviewed; Journal article, 2020)Sources of low-frequency fields are widely found in modern society. All wires or devices carrying or using electricity generate extremely low frequency (ELF) electric fields (EFs) and magnetic fields (MFs), but they decline ... -
Gardening in Polluted Tropics: The Materiality of Waste and Toxicity in Olive Senior’s Caribbean Poetry
(Journal article; Peer reviewed, 2022) -
Gas Anodes Made of Porous Graphite for Aluminium Electrowinning
(Journal article, 2017)One of the major downsides of the current aluminium production process is the high CO2 emission. One alternative is to replace the consumable carbon anodes with inert anodes so that oxygen evolves instead of CO2. Also PFC ... -
Gas cavity-body interactions: Efficient numerical solution
(Journal article; Peer reviewed, 2015)The paper investigates the interactions occurring between a gas cavity, the surrounding liquid and the nearby structures. In more detail, focus is in the characterization of the various dynamical phases (e.g. “acoustic ... -
Gas electrodes with nickel based current collectors for molten carbonate electrolyte thermo-electrochemical cells
(Journal article; Peer reviewed, 2019)Thermo-electrochemical cells with inexpensive molten carbonate electrolyte and (CO2|O2) gas electrodes allow the possible conversion of high temperature waste heat from industrial processes into electricity. The cell ... -
Gas Evolution in Li-ion Rechargeable Batteries: A Review on Operando Sensing Technologies, Gassing Mechanisms, and Emerging Trends
(Journal article; Peer reviewed, 2024)Gas evolution is fundamentally problematic in rechargeable batteries, and may lead to swelling, smoking, and device-level failure. In laboratories, monitoring gas evolution can help understand dynamic chemical events inside ... -
Gas Flow and Pressure Drop in Charge Material in Silicon Production
(Peer reviewed; Journal article, 2022)Gassing, outbursts of high-rate gas flows through the taphole, is a phenomenon that sometimes occurs during tapping of silicon furnaces. In addition to being an HSE challenge, this might also affect the tapping, while the ... -
Gas flow through shallow sediments - A case study using passive and active seismic field data
(Journal article; Peer reviewed, 2019)Offshore Quaternary sediment sequences are generally weak and unconsolidated, and fluid flow through these rock formations is hard to predict or model. Surface flow observations, such as gas seeps, often appear random and ... -
Gas Ion Source Performance of the EnvironMICADAS at HEKAL Laboratory, Debrecen, Hungary
(Journal article; Peer reviewed, 2021)A coupled accelerator mass spectrometer–gas interface system has been successfully operating at the Hertelendi Laboratory of Environmental Studies, Debrecen, Hungary, since 2013. Over the last 6 years more than 500 gas ... -
Gas phase amine depletaion created by aerosol formation and growth
(Journal article; Peer reviewed, 2017)Aerosols are systems of droplets or wet particles suspended in gases. In post combustion CO2 absorption systems aerosols can be formed by spontaneous phase transitions in supersaturated gas phases or by droplets or particles ... -
Gas switching reforming (GSR) for power generation with CO2 capture: Process efficiency improvement studies
(Journal article; Peer reviewed, 2019)This paper presents the process improvement studies of a combined cycle power plant integrated with a novel gas switching reforming (GSR) process for hydrogen production with integrated CO2 capture. The overall process is ... -
Gas Switching Reforming (GSR) for syngas production with integrated CO2 capture using iron-based oxygen carriers
(Journal article; Peer reviewed, 2019)The process behavior of a Gas Switching Reforming (GSR) reactor was studied using three different iron-based oxygen carrier materials: Iron-oxide on Alumina, Iron-Nickel oxide on Alumina and Iron-Ceria on Alumina. It was ... -
