DOI: 10.1002/cplu.202000175
Abstract: The heterofunctional lactone furo[3,4-b]pyridin-5(7H)-one (L1 ) undergoes a coordination-induced ring-opening reaction with Zn(NO3 )2 ⋅ 6H2 O to yield the zwitterionic [Zn(L1 ')2 (H2 O)2 ] (1, L1 '=2-(hydroxymethyl)nicotinate) with an uncoordinated carboxylate. The same reaction… read more here.

DOI: 10.1007/s11356-019-05143-9
Abstract: For remediating polluted soils, phytoextraction of metals received considerable attention in recent years, although slow removal of metals remained a major constraint in this approach. We, therefore, studied the effect of selected organic and inorganic… read more here.

DOI: 10.1007/s11356-020-08483-z
Abstract: Many industries discharge wastewater from processing into surface and underground waterways, and then, these waste waters must therefore be treated in order to remove heavy metals. The most common treatment used is the activated carbon… read more here.
