The depletion of Pt in Pt-enriched bond coats due to inter-diffusion with superalloys has been a critical concern for the long-term oxidation resistance thermal barrier coatings. This study investigated diffusion behaviour between CMSX-4 and two commercial comprising intermetallic ??/?-phase or ?-phase, aim understand mechanism that leads at high temperatures. results demonstrated superalloy di...

In those hands I see chipped plates, plastic sofa case, dripping taps, the smell of too little tenement light, of urine rained on hapless clothes, a smell her grandson will call stale and will define everything in life he will forever run from. Her sallow hands, atrophic from not holding and not being held, like garaged brush stiffened with last year’s paint; hands that rest, as she finishes, o...

Bacillus cereus T spores were prepared on fortified nutrient agar, and the spore coat and outer membrane were extracted by 0.5% sodium dodecyl sulfate-100 mM dithiothreitol in 0.1 M sodium chloride (SDS-DTT) at pH 10.5 (coat-defective spores). Coat-defective spores in L-alanine plus adenosine germinated slowly and to a lesser extent than spores not treated with SDS-DTT, as determined by decreas...

Thermal barrier coatings (TBCs) provide effective thermal barrier to the components of gas turbine engines by allowing higher operating temperatures and reduced cool‐ ing requirements. Plasma spraying, electron-beam physical vapor deposition, and sol‐ ution precursor plasma spray techniques are generally used to apply the TBCs on the metallic substrates. The present article addresses the TBCs f...

The objective of our work is to improve the osseointegration of titanium (and its alloys) used in dental and orthopedic applications. To do this, we have been coating these metals with glasses whose compositions are based upon Bioglass®, which is a bioactive glass developed by Hench et al. Bioactive glasses have the property of forming an apatite layer (and therefore can chemically bond to bone...

The thermal cyclic behavior of self-healing barrier coatings (SH-TBC) is analyzed numerically to develop a lifetime prediction model. Representative microstructures are studied adopting unit cell based multiscale modeling approach along with simplified evolution model for the thermally-grown oxide layer (TGO) study damage and healing in TBC system. fracture process modeled using cohesive zone-b...

The paper investigates seed coat characteristics (as a percentage of overall seed diameter) in Lupinus angustifolius L., a potential forage crop. In the study ten L. angustifolius genotypes, including three Polish cultivars, two Australian cultivars, three mutants originated from cv. 'Emir', and one Belarusian and one Australian breeding line were evaluated. The highest seed coat percentage was...
