For the analysis of polyoxometalate functionality (POM), a bioassay was developed in order to determine the effect of the functionalized porous ceramic granule (with POM) on the germination of tomato plantlets (Lycopersicon esculentum) and cowpea (Vigna unguiculata). After 3 days of incubation under dark conditions at room temperature in the case of cowpea seeds and 6 days in the case of tomato seeds, the germination process was calculated and the radicle and hypocotyl growths of the obtained plantlets were biomet...

The main objectives of the present study were: (1) to evaluate the impact of acid drainage, from the former Valea Vinului mine on the quality of Valea B?ilor creek and (2) to propose a treating method for the acid mine waters generated by the investigated mine. The waste waters sampled from the former Valea Vinului mine proved to be highly acidic having a pH between 3.1 and 5.2. The monthly fluctuation showed that during March 2016 and April 2016/2017 the waste waters were highly acidic. The acidic mine waters had...

Polyoxometalates (POMs) are discrete, anionic metal-oxygen clusters of early d bloc metal ions in high oxidation status (e.g. MoVI, WVI) with a very large structural and compositional variety, leading to interest in many different areas (catalysts in homogeneous and heterogeneous catalytic oxidation of organic compounds or biochemical reactions, activity in enzymatic redox processes, as antitumoral, antibacterial and antiviral treatments etc). An important subclass of POMs is the {XMo6O24} structure type, Anderson...
