The thermodynamic stability of onion-like carbon (OLC) nanostructures with respect to highly oriented pyrolytic graphite (HOPG) was determined in the interval 765-1030 K by the electromotive force (emf) measurements of solid electrolyte galvanic cell: (Low) Pt|Cr3C2,CrF2,OLC|CaF2s.c.|Cr3C2,CrF2,HOPG|Pt (High). The free energy change of transformation HOPG = OLC was found positive below 920.6 K ...
قالب های بزرگ صنعتی به دلیل ابعادشان مورد پوشش دهی به روشهای معمول PVD و CVD قرار نمیگیرند و از روش سنتی آبکاری کروم سخت به منظور افزایش مقاومت به سایش و طول عمر این قالبها استفاده میشود. امروزه این روش به دلیل آلودگیهای محیطی و محدودیتهای استفاده از ترکیبات سرطانزای Cr(VI) در حال جایگزینی با روشهای کمخطرتر و پربازدهتر است. هدف از این پژوهش جایگزینی این روش با روش پاشش حرارتی جهت افز...
Thermally sprayed cermet coatings are adequate solutions to improve cavitation and wear resistance of hydraulic turbines made stainless steel (SS), especially in rivers with a high sediment load, such as the Madeira River Brazil. However, some cermets easily dissolved river water, leading premature failure coating costly maintenance. Moreover, galvanic corrosion induced by coupling SS can accel...
Ryanodine receptors (RyRs), located in the sarcoplasmic/endoplasmic reticulum (SR/ER) membrane, are required for intracellular Ca2+ release that is involved in a wide range of cellular functions. In addition to Ca2+-induced Ca2+ release in cardiac cells and voltage-induced Ca2+ release in skeletal muscle cells, we recently identified another mode of intracellular Ca2+ mobilization mediated by R...
Our knowledge on the bonding mechanisms between the metal and ceramic parts of dental systems is very limited. This work tested the hypothesis that the details of the interface processes can be described in the framework of a chemical diffusion model. The development of interfacial phases was investigated by cross-sectional analytical transmission electron microscopy between a NiCr (Wiron 99) a...
