The polarity of the solvent used also has a significant effect on both the course of the reaction as well as the reaction rate. The site-selective siloxymethylation can be achieved in the case of cyclic acetals such as tetrahydrofuran (THF) and tetrahydropyrane (THP) derivatives, depending ...

In 2015, it was demonstrated (Gurkan et al., 2015) that with the choice of substitution in quinone structure and an IL with high polarity, the net CO2 separation capacity can be improved while also improving the efficiency (Figure 3A). The reduction and the consecutive CO2-binding potential...
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......

High-temperature CO2 electrolysis suffers from poor adsorp- tion and activation of the reactant, due to the linear molecules lacking polarity. This is believed to cause local starvation of CO2 in SOE cathodes1,3,7,12. Currently, preferential chemical adsorption of CO2 on solid oxide materials ...
Both polarity and solvent molecule size were somehow affecting the cluster coordination in different manners [43,44]. (Hf)PCN-224(H2,Co) easily coordinate OH groups or water molecules taking the place of bidentate linkers without affecting the Hf6(O/OH)8 core [45]. For instance, considering...
It has been generally thought that tRNA modifications are stable and static, and their frequencies are rarely regulated. N6-threonylcarbamoyladenosine (t6A) occurs at position 37 of five mitochondrial (mt-)tRNA species. We show that YRDC and OSGEPL1 are
6). A decrease in the solvent polarity provided very tight complexes. Furthermore, the hydrodynamic size of the complexes was in inverse proportion to the molecular weight of the PSS (Fig. 7). The Dh decreased with an increase in the molecular weight of the PSS. The formation of small ...
The SCH4 slightly increase by increasing the temperature, however, it shifted or affected by the IL polarity. The selectivities of different ILs toward H2S/CH4 or CO2/CH4 could be correlated using the Kamlet-Taft β factor that is based on hydrogen bond donating/ accepting as well as the ...
