Increased commercialisation of nanometal-based products augments the possibility of their deposition into aquatic ecosystems; this, in turn, may pose risks to aquatic biota and associated ecological functions. Freshwater invertebrate shredders mostly use microbially-colonized plant litter as food resource and play

Organic letters, 15(5), 996-999 (2013-02-15)
It is demonstrated that homogeneous N-heterocyclic carbene-copper(I)-chloride complexes can be prepared continuously by flowing NHC precursors through a packed bed of solid Cu(2)O suspended in molecular sieves. The method enables the synthesis of a wide range of complexes including those
