Developing imidazoles as CEST MRI pH sensors.

Xing Yang et al.

Contrast media & molecular imaging, 11(4), 304-312 (2016-04-14)

A series of intra-molecular hydrogen bonded imidazoles and related heterocyclic compounds were screened for their N-H chemical exchange saturation transfer (CEST) magnetic resonance imaging (MRI) contrast properties. Of the compounds, imidazole-4,5-dicarboxamides (I45DCs) were found to provide the strongest contrast, with

Imidazole-Modified Nanoporous Silica for Lead Ion Solid Phase Extraction Prior to Determination from Industrial Wastewaters by Flame Atomic Absorption Spectrometry.

Ali Behbahani et al.

Journal of AOAC International, 98(5), 1417-1422 (2015-11-04)

A new method was applied to produce modified nanoporous silica as a novel sorbent for Pb(II) ion SPE from industrial wastewater samples. In this modified method, the produced nanoporous silica has a higher functional group loading, which leads to a
