Using the recently proposed concept of dynamic nuclear polarization, which enables metabolic imaging, efficient acquisition have to be applied. Here, sequences for preclinical cardiac imaging of the metabolic substrates acetate and pyruvate were developed, and subsequently applied for the investigation of metabolic ch…
Vickers hardness indentations on AI2O3 were studied comprehensively. Beneath indentation, there is a well-defined interface between the plastic zone and the elastic region and the radius of the plastic zone is close to half the indentation diagonal length. The residual stress field around the indentations has been mea…
The powder X-ray diffraction allows direct investigation of the microstructure, and Rietveld refinement is one of the most widely used method for analyzing such data. The position of the profiles provide the network parameters, the intensity provides information on electron density, preferred directions and quantizati…
Preparation of mesoporous carbons and activated carbons has always been a resource-intensive process. When biomass is used as the raw material, an activating agent is typically mixed with the biomass and the mixture is activated by high temperature treatment. However, this might lead to ineffective utilization of the…
The self-polymerisation of dopamine has generated a wealth of interest, especially in the areas of drug delivery and encapsulation. However, the ideal encapsulation polymer should possess 1) ligating or chelating moieties in the shell to fixate drugs and metals to specific sites in the shell, 2) a simplistic method fo…
The isolation of 2D materials has attracted much interest in recent years. There are many isolation methods that have been created to study the properties of 2D material. Mechanical exfoliation method has proved to be a successful method to isolate bulk layered materials. In this project, the isolation and characteriz…
PVDF and PVDF/MgO nanocomposite thin films (MgO loading percentages 1, 3, 5, 7, 9 and 11 .wt%) were produced by spin coating on Al-glass substrates at 1500rpm. PVDF thin films were annealed subsequently at 70°C, 90°C, 110°C, 130°C, 150°C and 170°C, and then were cooled by fast cooling (FC) and slow cooling (SC). PVDF…
The performance of fusion devices is highly dependent on plasma-facing components. Tungsten is the most promising candidate material for armors in plasma-facing components in ITER and DEMO. However, the brittleness of tungsten below the ductile-to-brittle transition temperature is very critical to the reliability of p…
Research and development in the area of nanoscience and nanotechnology offer new opportunities for making superior nanomaterials (NMs) having an enormous economic potential for new drugs and medical treatments, electronics, and environmental remediation. Due to the large production volume of NMs, manufactured nanopart…
In this work presents features of the Baushinger effect and strain aging after alternating deformation of low carbon steel pipe with ferrite-pearlite and ferrite-bainite structure. It has been established that ferrite-bainite structure has more tendency to Bauschinger effect. Aging after application of the alternating…
A impregnação de polímeros com princípios ativos de fármacos usando o dióxido de carbono a alta pressão constitui-se em uma das formas de processamento de polímeros para obtenção de sistemas de liberação controlada. A modelagem e a simulação do processo de impregnação são especialmente importantes para a previsão da v…
Sonokemija je podrocje kemije, kjer kemijske reakcije potekajo pod vplivom zvocne energije, imenovane ultrazvok. Ukvarja se z razumevanjem ucinka zvocnih valov na kemijske sisteme. Namen nase diplomske naloge je bil sintetizirati razlicne modifikacije bakrovih metanoatov z uporabo klasicnih metod kot tudi z metodami s…
High-surface-area porous materials like activated carbon are employed as active material of electric double layer capacitor (EDLC). In charging and discharging an EDLC, ion migrates in the electrolyte solution in the pores inside the particles of active material as well as in the interstices between the particles. At…
Globalization and climate change have driven the need to develop new technologies which can provide clean, plentiful energy from renewable sources. This work was focused on the application of nanostructured π-electron materials derived from carbon-based macromolecules towards capturing, converting, and storing energy.…
We address RuO2 nanoparticles as an appealing link between single-crystal model and real (supported) catalysts. From a first-principles based Wulff construction under explicit consideration of a CO oxidation reactive environment we deduce a prominent role of hitherto little studied, apical RuO2(111) facets for the lon…
Male and female Scylla serrata juvenile crabs were stocked separately in cement ponds (14 x 8 x 0.8 m; 90 m3) and reared for 90 days. The study was conducted at the Fisheries Research Station, JAU. Okha, Gujarat. The crabs were fed trash fish and Trochus spp.\nThe survival rates of male and female crabs were higher in…
In recent year, natural fiber becomes an environmental advantage due to the environmental alertness.The goal of current study was to investigate the mechanical behavior of hybrid jute/flax epoxy composite based on the tensile properties.The jute twill and flax plain weave were laminated to produce a range of ligt weig…
Li0.5Bi0.5TiO3 ceramic powder was synthesized by high energy ball milling. The X-ray diffraction pattern of the sample was analyzed in a quantitative manner using rietveld analysis. X-rays is the finger print of a material and the diffracted intensity can be used to dig out a lot of information related to the material…
Titanate nanotubes were synthesized under hydrothermal conditions from TiO2 powder, followed by HCl rinsing. The properties of prepared nanotubes were investigated in detail by various analytic techniques such as field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Fourier transformed infra-re…
