A step by step increase of the skeleton rigidity of the polythiophene networks P-TTT, P-THIDT and P-DTBDT by monomer design. The monomers’ rigidity had intense influence on the stacking morphology and porosity structure of the obtained polythiophenes.

Magnetism, a conjugated π-system and ultramicropores are combined in one multifunctional bulk material with a core@shell structure for dynamic and static pollutant treatment.

A simple and rapid potentiometric method for the estimation of ascorbic acid in pharmaceutical dosage forms has been developed. The method is based on treating ascorbic acid with iodine and titration of the iodide produced equivalent to ascorbic acid with silver nitrate using Copper Based Mercury Film Electrode (CBMFE) as an indicator electrode. Interference study was carried to check possible interference of usual excipients and other vitamins. The precision and accuracy of the method was assessed by the application of lack-of-fit test and other statistical methods. The results of the proposed method and British Pharmacopoeia method were compared using F and t-statistical tests of significance.
