Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

A Cyclic {NiII8DyIII4} Cluster Where the DyIII Moments Are Organized by the Transition Metal Spins

Chemistry – A European Journal, EarlyView.
The synthesis, structural characterisation, and magnetic properties of a cyclic Ni8Dy4 coordination cluster are reported. Ab initio CASSCF and DFT calculations help rationalize the shape of the microSQUID hysteresis and the competing magnetic interactions within the compound. ABSTRACT A series of [Ni8Ln4(CO3)4(L)8(NO3)2(H2O)8 (MeOH)4](NO3)2 (Ln = Dy (1)
