Diesel engines being inferior in their emission characteristics are under greater scrutiny. Intensive research efforts are ongoing for improving fuel consumption and exhaust emissions from diesel engines. For improving performance of engine, Ceramic based Thermal barrier Coating plays a major role. Tests were performed on four stroke, single cylinder, DI diesel engine whose piston crown, cylind...

Due to its bioactivity, hydroxyapatite (HAp) is one of the most perspective materials for controlled drug delivery. Biodegradable polymers like chitosan and sodium alginate are used as coating materials for ceramic scaffolds. In this work the application of HAp/sodium alginate or chitosan composite materials which provide controlled lidocaine release is discussed. The polymers and lidocaine hyd...

A new technique for characterizing end-supported microbeams of coating materials is presented. Microbeams are fabricated using micro-EDM machining to isolate the material under investigation from the underlying substrate. Threeand four-point bending is realized by a custom-built microspecimen testing system, and digital image correlation is employed to capture full-field strains and displacemen...

ZnO, Al-doped ZnO (AZO), and Ga-doped ZnO (GZO) semiconductor thin films were deposited on glass substrates via a sol-gel spin-coating process for application in a photoconductive ultraviolet (UV) detector. The doping concentrations of Al and Ga were 1.0 at % in the precursor solutions. In this study, the microstructural features and the optical and electrical properties of sol-gel-derived ZnO,...

β-Tricalcium phosphate (β-TCP) is an attractive ceramic for bone tissue repair because of its similar composition to bone mineral and its osteoconductivity. However, compared with other ceramics β-TCP has a rapid and uncontrolled rate of degradation. In the current study β-TCP granules were mineral coated with the aim of influencing the dissolution rate of β-TCP, and also to use the coating as ...
