Structural and morphological characterizations of glass based composites in thin films form

By using a low-cost sol gel method, neat and loaded phosphate glass containing Cr, Co, Ni, and Zn was synthesized and then placed on a silica glass substrate. Cr, Ni, Co, and Zn loading amounts were diluted inside the matrix using rates varying from 0 wt% to 16 wt% in order to study the impact of loading elements on glass characteristics. By using XRD and SEM, it was determined how loading factors affected the structural and morphological characteristics of glass thin layers. When the annealing temperature was maintained at 250 °C, X-ray diffractograms revealed that the deposited glass films had an amorphous nature, whilst also X-ray pattern results revealed that the loaded films had a low crystalline nature. Morphology studies indicated the homogeneity and the edge of crystallinity of the obtained thin films. All results were described in detail and they indicated that the films prepared in this study can be used in many nanotechnology applications

Formulation, optimization of a poultry feed and analysis of spectrometry, biochemical composition and energy facts

Poultry feed plays a key role in the success and economic profitability of poultry production. When formulating an effective feed, its cost and nutritional quality to cover the essentials of poultry must be taken into account. For this reason we tried to make an optimal poultry feed in quality and price, so we collected samples for this study The collection was organized to cover as much variability as possible related to seasons, suppliers, origins. Analysis must be done to discover the biochemical compositions and nutritional energy of the primary trades that lead to a formula to produce poultry feed, this formula is realized by linear programming technique to manufacture feed for three categories of poultry (starter (0–4 weeks), grower (4–18 weeks) and layer chickens (18 weeks to culling)). we analyze the samples by the near infrared spectrometry (NIRS), and to confirm the spectrometric results, we do deferent chemical analysis. Finally we obtain a database that guides us to interpret the optimal percentages for the manufacture of poultry feed

Synthesis of N-CNT/TiO

In this study, we have investigated the surface analysis and optoelectronic properties on the synthesis of N-CNT/TiO2 composites thin films, using sol gel method for a dye synthetized solar cell (DSSC) which is found to be simple and economical route. The titanium dioxide based solar cells are an exciting photovoltaic candidate; they are promising for the realization of large area devices. That can be synthetized by room temperature solution processing, with high photoactive performance. In the present work, we stated comparable efficiencies by directing our investigation on obtaining Sol Gel thin films based on N-CNT/TiO2, by dispersing nitrogen (N) doped carbon nanotubes (N-CNTs) powders in titanium tetraisopropoxyde (TTIP). The samples were assessed in terms of optical properties, using UV—visible absorption spectroscopic techniques. After careful analysis of the results, we have concluded that the mentioned route is good and more efficient in terms of optoelectronic properties. The gap of “the neat” 0.00w% N-CNT/TiO2 is of 3eV, which is in a good agreement with similar gap of semiconductors. The incorporated “w%NCNTs” led to diminishing the Eg with increasing N-CNTs amount. These consequences are very encouraging for optoelectronic field

CNTs modified ZnO and TiO

ZnO and TiO2 are direct wide band gap semiconductors with intriguing properties. A wide range of applications makes it one of the most studied materials in the past decade, particularly when elaborated as nanostructures. In this work, we focus on synthesis of CNTs modified ZnO and TiO2 thin films using sol-gel method. The morphological and optical characterizations of the based ZnO and TiO2 films were carried out using scanning and transmission electron microscopy (SEM and TEM), XRD and UV spectroscopy. Electrical properties of the deposited ZnO/CNTs and CNTs /TiO2 were studied using I-V measurements at room temperature in metal/semiconductor/metal configuration, by the use of an array of metallic micro-electrodes deposited on the surface of the elaborated thin films. This allows determining qualitatively the electrical conductivity of thin films and the different parameters of the Schottky junction between the composites nano-films and the substrate. This study is necessary for future applications in solar cell
