The influence of the chain length and the functional group steric accessibility of thiols on the phase transfer efficiency of gold nanoparticles from water to toluene
(West Pomeranian University of Technology, Szczecin, POLAND, Publishing House, 2014)This paper describes the influence of the chain length and the functional group steric accessibility of thiols modifiers on the phase transfer process efficiency of water synthesized gold nanoparticles (AuNPs) to toluene. ... -
The substituent effect on benzene dications
(RSC Publishing, 2014-01-03)It was recently postulated that the benzene ring and its 4n + 2 p-electron analogues are resistant to the substituent effect due to the fact that such systems tend to retain their delocalized character. Therefore, the 4n ... -
