Highly porous and machinable nanohydroxyapatite–gelatin scaffold was prepared through the freeze casting technique. Mechanical properties, particularly compressive strength, were improved after curing in liquid nitrogen. Cryogenic temperature (77K) reduced the hydrocarbon bond length, anchored the nanorod HAp particles within organic matrix of original scaffolds and altered the stress–strain characteristics...
We report the preparation of ordered polyaniline nanorod arrays by a simple method without the use of any template. The synthesis method is by a chemical route, viz. dispersion polymerization of aniline in polyvinyl alcohol. The nanorods obtained have a diameter of 100–500 nm and a length of a few micrometers. Films containing the nanorod assembly have been characterized by SEM, XRD and FTIR spectroscopy...
