Morphology control

Alginate-stabilized Cu2O@Cu nanoparticles were fabricated by chemical reduction method using nature polymer alginate as a stabilizing agent. Transmission electron microscopy (TEM), X-ray powder diffraction (XRD), infrared (FT-IR) spectrum, and UV-Vis analysis were used to investigate the morphology, size, structure, and stability of the nanoparticles synthesized.

CuO nanoparticles were synthesized by alcohol-assisted hydrothermal method at various pH values, using sodium hydroxide as a precursor for pH control. The chemical composition, morphological and structural properties of the obtained CuO nanoparticles were investigated by the Raman and energy-dispersive X-ray spectroscopies, the field-emission scanning electron microscopy, and the X-ray diffraction.

This study describes the sedimentary facies and depositional architectures of Gilbert-type and shoal-water delta deposits developed on opposed margins of the extensional fluvio-lacustrine Yalvaç Basin during the late Cenozoic. The roles of syndepositional tectonism, basin dynamics, and hinterland morphology on the development of different delta types are assessed. This asymmetric trough initially opened as an intramontane molasse basin to the southwest of the Sultandağları massif.

This thesis provides a list of natural enemy species for agricultural insect pests in Dong Thap Province. Data about morphological, biological, behavioral and ecological characteristics of A. calandrae parazitizing L. serricorne is also obtained. Besides, the ability to control S. zeamais and L. serricorne was shown in this study.

Silver nanowires with one-dimensional structures have attracted much research interest due to their potential applications in several areas. It is well-known that their properties strongly depend on the size and morphology of the silver nanostructures. Therefore, in our work, silver nanostructures were prepared using a polyol process and the effects of synthesis conditions on the formation and morphology of silver nanowires were investigated.

A finite-state machine is described which will control the derivation of Italian verb forms, including proper stress placement, given an appropriate dictionary and set of grammatical rules.I. Introduction In many languages a word may be identified, on the syntactic level, by a single vocabulary element or lexeme and a single term from each of a set of closed grammatical categories.

In the biomineralization processes, proteins are thought to control the polymorphism and morphology of the crystals by forming complexes of structural and mineral-associated proteins. To identify such proteins, we have searched for proteins that may form high-molecular-weight (HMW) aggregates in the matrix of fish otoliths that have aragonite and vaterite as their crystal polymorphs.
