In this context, there have been very few attempts to employ organocatalytic hydrogen bond donors (HBDs) in the cycloaddition reaction of CO2 to EFAEs and EVOs and no studies focusing on bio‐based and readily available HBDs. In this work we show that ascorbic acid is an efficient HBD for...
The Nature of the Chemical Bond Revisited: An Energy‐Partitioning Analysis of Nonpolar Bonds The nature of the chemical bond in nonpolar molecules has been investigated by energy-partitioning analysis (EPA) of the ADF program using DFT calculations......
TOUGH-FLAC [111] is a multi-purpose code for porous materials with applications extending from nuclear waste repositories to underground storage of CO2 and multi-phase geothermal reservoirs [166]. It sequentially couples the geomechanical code FLAC3D [164] with the multi-phase flow and heat transpor...

Compared to H2-assisted activation mode, the direct dissociation of CO2 into carbonyl (*CO) with a simplified reaction route is advantageous for CO2-related synthetic processes and catalyst upgrading, while the stable C = O double bond makes it very challenging. Herein, we construct a subna...

After the 2C transgenic mice were sacrificed via CO2 induction with a fill rate of 1.7–3.9 L/min with 30–70% of the chamber filled per minute, the spleen was harvested to isolate T cells. After being packed into the red biohazard bag, the bodies of the sacrificed mice were ...

Relation between Volume Expansion and Hydrogen Bond Networks for CO2−Alcohol Mixtures at 40 °C We experimentally determined the density and mole fraction of CO2 (xCO2) for CO2−alcohol (methanol, ethanol, propanol, butanol, isopropyl alcohol, and t... Tsutomu,Aida,Takafumi,... - 《Journal...
What is the hybridization of the central atom in CO2? How many hydrogen atoms can bind to one carbon atom? What are the shapes of orbitals? How many electrons are in the P orbital? What is a tetrahedral molecule? How many electrons are in a double bond?
