In aerospace applications, Iron-Nickel (Fe–Ni) alloys are first choice of structural designers, whenever high strength and low thermal expansion are required for spacecraft subsystems. Fe–Ni alloy have an extraordinarily minimum thermal expansion, and dimensions were nearly invariable even at cryogenic temperatures, popularly it is called Invar. Th...

Supramolecular chemistry is one of the most vigorous and fast-growing fields in chemistry.It is of great interest to study when four/six/eight or more functional groups are present on one single molecule/macrocycle. Certainly it will exhibit some extra binding properties (which are yet to be discovered).Wecan design and synthesize some novel supramolecular assemblies derived from Calix system for simultaneous detection, extraction, separation and preconcentration of various toxic or detrimental ions from aqueous environmentalis the current description of the project.
