Utilization of a CO₂ Storage Material: Shape-Controlled Preparation of CaCO₃ Microspheres

Crystals, 2019
Homogeneous CaCO3 microspheres were controllably synthesized via a simple hydrothermal method without using extraneous additives by Ca(OH)2 saturated solution reacted with CO2 storage material (CO2SM), which was obtained by absorbing CO2 gas in a system ...

COVID-19 causes record decline in global CO2 emissions [PDF]

, 2020
The considerable cessation of human activities during the COVID-19 pandemic has affected global energy use and CO2 emissions. Here we show the unprecedented decrease in global fossil CO2 emissions from January to April 2020 was of 7.8% (938 Mt CO2 with a

CO2 Ice toward Low-luminosity, Embedded Protostars: Evidence for Episodic Mass Accretion via Chemical History [PDF]

, 2012
We present Spitzer IRS spectroscopy of CO2 ice bending mode spectra at 15.2 micrometer toward 19 young stellar objects with luminosity lower than 1 Lsun (3 with luminosity lower than 0.1 Lsun). Ice on dust grain surfaces can encode the history of heating

Cardiovascular Impacts on COVID-19 Infected Patients

Frontiers in Cardiovascular Medicine, 2021
The SARS-CoV-2 virus has taken more than 2 million lives on a global scale. Over 10 million people were confirmed with COVID-19 infection. The well-known spot of primary infection includes the lungs and the respiratory system.

Stratospheric measurements of continuous absorption near 2400 cm^-1 [PDF]

, 1981
Solar occultation spectra obtained with a balloon-borne interferometer have been used to study continuous absorption by N2 and CO2 near 2400 cm^-1 in the lower stratosphere.

The study of CO2 absorption intensification using porous media material in aqueous AMP solution

Petroleum, 2018
In this work, the performance of CO2 absorption into aqueous 2-amino-2-methyl-propanol (AMP) solution was investigated by measuring the amount of CO2 in the liquid phase during CO2 absorption process to identify initial CO2 absorption rate.

Great SCO2T! Rapid tool for carbon sequestration science, engineering, and economics

, 2020
CO2 capture and storage (CCS) technology is likely to be widely deployed in coming decades in response to major climate and economics drivers: CCS is part of every clean energy pathway that limits global warming to 2C or less and receives significant CO2

Improved quantification of Chinese carbon fluxes using CO2/CO correlations in Asian outflow [PDF]

, 2004
[1] We use observed CO2:CO correlations in Asian outflow from the TRACE-P aircraft campaign (February–April 2001), together with a three-dimensional global chemical transport model (GEOS-CHEM), to constrain specific components of the east Asian CO2 ...
