摘要： An antimicrobial composition including low molecular weight dendrimers of formula (I): Q is an antimicrobial moiety in monomer or dendritic form, N is a nitrogen atom, L2 is a linker linking each Y1 molecular spacer to the nitrogen atom, is a molecular spacer spacing each antimicrobial moiety Q from the L2 linker, there are two or more chains of antimicrobial moieties and molecular spacers, X is a linker configured to covalently bond to surface functionalities of the substrate, and Y2 is a molecular spacer between the linker X and the nitrogen atom.

摘要： A method of separating scandium from a feedstock wherein a scandium enriched solution is produced from the feedstock and the scandium enriched solution is extracted to produce an organic phase of the scandium enriched solution. The organic phase of the scandium enriched solution is re-extracted to produce an aqueous phase including scandium chloride. The aqueous phase is precipitated and calcinated to produce scandium oxide powder.
