TLDR
Rod-, twinrod-and tetrapod-shaped CdS nanocrystals have been successfully prepared from the starting spherical Cs via a highly oriented solvothermal recrystallization technique as mentioned in this paper, which may open a new doorway to one-dimensional nanosized semiconductors from the same kind of materials with irregular shape or larger size.Abstract:
Rod-, twinrod- and tetrapod-shaped CdS nanocrystals have been successfully prepared from the starting spherical CdS nanocrystals via a highly oriented solvothermal recrystallization technique. X-Ray powder diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy and high-resolution transmission electron microscopy have been used to characterize the crystal structure and growth direction of the obtained sample. The present technique may open a new doorway to one-dimensional nanosized semiconductors from the same kind of materials with irregular shape or larger size.read more

Controlled growth of tetrapod-branched inorganic nanocrystals
TL;DR: It is demonstrated that polytypism, or the existence of two or more crystal structures in different domains of the same crystal, coupled with the manipulation of surface energy at the nanoscale, can be exploited to produce branched inorganic nanostructures controllably.

TL;DR: Oxygen storage capacity (OSC) measurements at 400 degrees C revealed that the oxygen storage takes place both at the surface and in the bulk for the as-obtained CeO2 nanorods and nanocubes, but is restricted at thesurface for the nanopolyhedra just like the bulk one, which suggests that high OSC materials might be designed and obtained by shape-selective synthetic strategy.

TL;DR: This paper proves that Cd(CH3)2 can be replaced by CdO and develops a one-pot synthesis which does not require separated preparation of cadmium complex and is reproducible and simple and thus can be readily scaled up for industrial production.
