A hybrid scaffold based on polyvinyl alcohol and bioactive glass ceramics was synthesized and characterized for its biocompatibility and its degradation behavior. Poly vinyl alcohol and glass ceramics were mixed in the ratio 70:30 by weight percentage. The glass ceramic was based on 65 % SiO2, 5 % P2O5 and 30 % CaO. A…
This work presents the buckling analysis of functionally graded single walled carbon nanotubes reinforced composite plates under in-plane mechanical loads. The effective material properties of uniformly distributed carbon nanotubes are obtained using Mori–Tanaka approach and extended rule of mixtures. The buckling loa…
L'objet de ce travail concerne une étude sur la modélisation des phénomènes électromagnétiques dans une machine à reluctance variable (MRV) qui sont à la base de son fonctionnement et de sa commande. Après un rappelle des différentes types de machines électriques avec différents cas de figures et types de MRV, nous pr…
Ferroelectrics have experienced a great deal of interest for more than half a century. Initially, ferroelectric ceramics were used as capacitor materials due to their high dielectric constants. With the preface of lead-zirconate-titanate (PZT), applications spread to transducers, actuators and many others. But because…
Spin torque oscillators (STOs) are magnetic nano-devices in which strongly non-linear magnetodynamic phenomena can be excited by current. In this thesis, we study some of these phenomena by means of micromagnetic simulations, analytical calculations, and electrical characterization. Three main subjects are discussed:\…
BNT-BT [(0.93Bi0.5Na0.5)TiO3- 0.07Ba-TiO3 ] and BNT-KNN [(0.93Bi0.5Na0.5)TiO3 – 0.07K 0.5 Na 0.5 NbO3 ] was prepared by the solid state route using microwave process. The prepared sample was calcined at 900°C for 10 minutes by microwave process for both BNT-BT and BNT-KNN. Then the sample was characterized by differen…

Mit der Herabsetzung der Partikelgröße kann sich die Wahrscheinlichkeit für eine spontane Pyrophorität bei Kontakt mit Luft erhöhen. Für die Herstellung von nanometerskaligen und mikrometerskaligen Partikeln gibt es sowohl neuentwickelte als auch lange bestehende Verfahren. Aber nicht alle Verfahren sind optimal für d…

Les techniques d’analyse thermique et de calorimetrie sont des methodes d’essai largement utilisees dans les laboratoires d’analyse physico-chimique, pour des finalites de recherche ou de controle qualite. Comme tout appareil de mesure, un analyseur thermique ou un calorimetre doit etre etalonne en temperature et en e…
Utilização do licor proveniente da hidrólise da polpa de sisal como substrato para a produção de biossurfatanteOs surfatantes são substâncias químicas que têm uma ampla aplicação industrial principalmente como matéria-prima na fabricação de detergentes.No entanto, estas substâncias de origem sintética podem ser substi…
For improvement of pavement of road, the use of asphalt material and its mixture are used so that their durability and performance can be enhanced. For which the suitable mixture that is been adopted is SMA Mix (Stone mastic asphalt or Stone matrix asphalt) which is better than bituminous Concrete or dense graded mix…
In the dairy industry, the milk processing leads to the formation of undesirable deposits. Due to the lack of solutions to minimize these deposits and to ensure the safety and quality of transformation, cleaning processes with both economic and environmental impacts are commonly performed. Setting optimal processing c…
The modern dynamic world can’t imagine its development without bringing the concept of advancement in material composite. Various researches are going on in this field to achieve the desired standard. Natural fiber reinforced polymer composite has a huge affinity to replace the composite made up of synthetic fiber. Th…
Fiber reinforced polymer composites is an important class of structural material due to their numerous advantages. Reinforcement in polymer is either engineered or characteristic. Engineered fiber, for example, glass, carbon and so on has high particular quality however their fields of requisition are restricted becau…
In our work study is done on the effect of spinelization using different commercially available raw materials of magnesia and alumina. In the study 16-SG, and CL-370 grade of alumina used, and fused magnesia, Netherland magnesia and chemical grade magnesia are used. The spinelization is done using solid state reaction…
Measurements of the absorption coefficient, α/f2, of aqueous solutions of α-cyclodextrin with alkylpyridinium bromides CnH2n+1C5H4NBr or alkyltrimethylammonium bromides CnH2n+1N(CH3)3Br (n = 8, 10, 12), were carried out at 15, 25, 35 and 45°C in the concentration range 0.01 M to 0.04 M and frequency range 1 MHz to 150…
Zinc Oxide (ZnO) nanostructures with their significant properties have various application in optoelectronics, sensor devices and energy conversion devices.
