Tio2 Nanomaterials

It is important to determine the assembly configuration of engineered nanomaterials (ENMs) because assembly configuration influences their fate and transport behavior in the aquatic environment. Aggregated particles are more subject to segregation upon changes of environmental conditions (and vice versa) than agglomerated particles. As a strategic tool for investigating the time-resolved reversible segregating and assembling behavior of ENMs and thus estimating their assembly configuration, a controlled sonication process was proposed. It was hypothesized that the unique colloidal response of ENMs to sonication, with respect to changes in size, might be their intrinsic property associated with assembly configuration. As a model ENM, three different TiO2 particles with unique properties (commercial P-25 and UV 100 and home-made (HM) TiO2) were examined with programmed sonication processes under various environmental settings. When they were dispersed in water, all TiO2 particles tested obviously assembled to form much larger clusters. Size of P-25 decreased immediately upon sonication and did not change under the subsequent quiescence step while sizes of UV 100 and HM gradually decreased and then slowly recovered back to their initial sizes. The trend was generally observed in all conditions tested. The unique colloidal response of TiO2 could be explained by its properties associated with assembly configuration.

Combining ability has been proved to be a method to identify and select the parents and hybrids for increased production through the exploitation of heterosis. The exploitation of heterosis would be useful if suitable hybrids are produced for low yielding environmental conditions of littoral sandy soil. Combining ability effects for early germination, seedling girth, seedling height and breadth of laminate leaf on coconut have been reported by Louis and Chopra (1991) and on husked nut weight by Fernando (1996).  Estimation of GCA and SCA variance will help to find out the gene action involved in a particular character and thus one can decide the breeding method for the improvement of the character. The present investigation was carried out to find out the general and specific combining ability effects of parents and hybrids at Central Plantation Crops Research Institute, Kasaragod.
