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...

A planar Bi–Sb multijunction thermal converter was fabricated on the LPCVD Si3N4/SiO2/Si3N4-diaphragm, prepared by silicon bulk micromachining, which thermally isolated a bifilar Ptor NiCr-heater and the hot junctions of a Bi–Sb thermopile from the silicon substrate. The voltage responsivity, the ac–dc transfer difference, and the fluctuations of the output thermoelectric voltage and heater res...

Highly scattering plasma-sprayed thermal barrier coatings (TBCs) present a challenge for optical diagnostic methods to monitor TBC delamination because scattering attenuates light transmitted through the TBC and usually degrades contrast between attached and delaminated regions of the TBC. This paper presents a new approach where reflectance-enhanced luminescence from a luminescent sublayer inc...

The transmission line pulse method (TLP) is used to characterise the reliability of bolometric GaAs microwave power-sensors. Two degradation mechanisms are identified during the degradation process of the absorbing NiCr termination, in which the input power is converted into heat. Simulations and a material analysis have been performed in order to characterise the observed degradation mechanisms.

Abstract The effect of metal core on flame spread behavior over polyethylene (PE)-insulated electrical wire was experimentally investigated by varying applied AC voltage (VAC) and frequency (fAC). present experimental results with Cu-core were compared those conducted previously NiCr-core. Flame rate (FSR) for the baseline case no electric field larger than that Both FSR size appreciably influe...

Herein, the fabrication and electrical characterization of multilayer black phosphorus (BP)-based field effect transistors with Ni or NiCr alloy contacts are reported. The devices show p-type conduction hysteresis in transfer characteristics that enable their use as nonvolatile memories. differences between investigated Y-function method is applied to extract channel mobility up 112 cm2 V−1 s−1...
