Anthracene oil was first distilled in a single lot up to 360°C, and the total quantity of solids that separated out on cooling at ordinary temperature (room temperature), and on cooling at 0°C for a week and for a month ... -
Isonitroso-keto-imino Nicle (II) complexes-A study in ambidentate coordination.
In conclusion, it may be said that the isolation of the present complexes reveals the wider occurrence of linkage isomerism in isonitroso-p-keto-imine ligand complexes. These belong to the rare type of complexes where the ... -
Itaconate Based Dual-reactive Polymeric Coatings and Photo-cross-stitching Studies of Periodically Grafted Amphiphilic Systems
Dual-reactive coatings are those that covalently anchor to the substrate while at the same time permit installation of desired segments in a post-coating step; several approaches have been developed to design such polymers ... -
Itaconate Based Novel Amphiphilic Polymer Architectures
Amphiphiles are natural or synthetic molecules consisting of hydrophilic polar head group and hydrophobic non-polar hydrocarbon tail. Beyond a certain concentration, known as critical micellar concentration (CMC), amphiphilic ... -
