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

Frontiers 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)

Molecules, 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 ...

Scalable carbon dioxide electroreduction coupled to carbonylation chemistry

Nature 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

Cooperative redox activation for carbon dioxide conversion

Nature 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]

E3S 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.

Carbon footprint of Power-to-X derived dimethyl ether using the sorption enhanced DME synthesis process

Frontiers in Sustainability, 2022
Dimethyl ether (DME) could have a promising future as a sustainable diesel fuel replacement as it requires only relatively minor engine modifications. It can be produced from renewable H2 and captured CO2 using Power-to-X technologies.

Fiber Optic Sensing for Geomechanical Monitoring: (2)- Distributed Strain Measurements at a Pumping Test and Geomechanical Modeling of Deformation of Reservoir Rocks

Applied Sciences, 2019
In this study distributed fiber optic sensing has been used to measure strain along a vertical well of a depth of 300 m during a pumping test. The observed strain data has been used in geomechanical simulation, in which a combined analytical and ...

Integrated CO2 Capture and Utilization Using Non-Thermal Plasmolysis

Frontiers in Energy Research, 2017
In this work, two simple processes for carbon dioxide (CO2) such as capture and utilization have been combined to form a whole systems approach to carbon capture and utilization (CCU).

Gridded uncertainty in fossil fuel carbon dioxide emission maps, a CDIAC example [PDF]

Atmospheric Chemistry and Physics, 2016
Due to a current lack of physical measurements at appropriate spatial and temporal scales, all current global maps and distributions of fossil fuel carbon dioxide (FFCO2) emissions use one or more proxies to distribute those emissions.
