Case study on amplitude and phase response comparison between DAS and 3C geophone VSP surveys at a test site in Japan

open access: yesFrontiers in Earth Science, 2022
Distributed acoustic sensing (DAS) is an effective tool for seismic surveys and is widely used as the preferred sensor for acquiring dense Vertical Seismic Profile (VSP).

Ideal Adsorbed Solution Theory (IAST) of Carbon Dioxide and Methane Adsorption Using Magnesium Gallate Metal-Organic Framework (Mg-gallate)

open access: yesMolecules, 2023
Ideal Adsorbed Solution Theory (IAST) is a predictive model that does not require any mixture data. In gas purification and separation processes, IAST is used to predict multicomponent adsorption equilibrium and selectivity based solely on experimental ...

Wellbeing of Alcohol-preferring Rats Euthanized with Carbon Dioxide at Very Low and Low Volume Displacement Rates [PDF]

open access: yes, 2019
The 2013 AVMA Guidelines on Euthanasia recommend the use of very-low or low flow rates of 100% carbon dioxide to euthanize small rodents. Although inhalation of high concentrations of carbon dioxide are generally recognized as painful in humans, whether ...

Scalable carbon dioxide electroreduction coupled to carbonylation chemistry

open access: yesNature Communications, 2017
Electroreduction of CO2 to CO is a potential valorisation pathway of carbon dioxide for fine chemicals production. Here, the authors show a user-friendly device that couples CO2 electroreduction with carbonylation chemistry for up to gram scale synthesis

Carbon Dioxide Splitting: A Summary of the Peer-Reviewed Scientific Literature [PDF]

open access: yes, 2008
Increasing concentrations of carbon dioxide (CO2) in the atmosphere have stimulated significant global research and development efforts regarding the reduction in CO2 emissions from all point and non-point sources. In addition to technologies that do not

Carbon Dioxide Angiography [PDF]

open access: yesSeminars in Interventional Radiology, 2008
The algorithm for patients with renal insufficiency who require vascular imaging has recently changed in my hospital. Previously, the majority of these patients underwent magnetic resonance angiography (MRA) or occasionally computed tomographic angiography after prescan hydration and sodium bicarbonate infusion.

Cooperative redox activation for carbon dioxide conversion

open access: yesNature Communications, 2016
While CO2 can be converted to CO for further reactivity, typically this involves the generation of large amounts of waste. Here the authors report the conversion of CO2to CO, with the siloxane by-product being further used in a carbonylative Hiyama ...

Green synthesis approach using deep eutectic solvents to enhance the surface functional groups on porous carbon for CO2 capture [PDF]

open access: yesE3S Web of Conferences
This study explores the potential of green solvents using amino acids-based deep eutectic solvents to alter surface functionality of activated carbon thus enhancing the carbon dioxide (CO2) adsorption capacity.
