Coal Geology & Exploration
Deep coal seam CO2 geological sequestration and enhanced CH4 recovery(CO2-ECBM) can both increase CBM recovery and achieve carbon emission reduction, possessing dual benefits of energy and environment. The geochemical reactions between supercritical CO2(ScCO2), water and coal seam roof can change its physical-mechanical properties and increase the risk of CO2 leakage. In this paper, taking the roof rock of No.3 coal seam in Hudi Mine from Qinshui Basin as the research area, the ScCO2-water-rock geochemical reaction simulation experiment was carried out to explore the geochemical reaction process of ScCO2 …

New England Journal of Public Policy
One of the most important responsibilities the United States assumed following World War II was ensuring the stable flow of relatively inexpensive oil to the industrialized and industrializing countries of the world. A glance at a list of the top petroleum exporting countries shows that most of them are poor, have despotic governments, and experience frequent bouts of political instability and ideological extremism.

International Bulletin of Political Psychology
The author discusses how "the environment" is no longer a fringe Issue championed by starry-eyed dreamers and psychodynamic deviants, and perennial misfits who have little understanding of or orientation to reality. In fact, the relevance of "the environment" for policies of political security has become quite significant.
