Photoconductivity in YIG Doped with Si, Ca and Sr

X-ray induced persistent photoconductivity in Si-doped Al0.35Ga0.65As

We demonstrate that x-ray irradiation can be used to induce an insulator–metal transition in Si-doped Al0.35Ga0.65As, a semiconductor with DX centers. The excitation mechanism of the DX centers into their shallow donor state was revealed by studying the photoconductance along with fluorescence. The photoconductance as a function of incident x-ray energy exhibits an edge both at the Ga and As K ...

The Effect of Bi-Sr and Ca-Sr Interactions on the Microstructure and Tensile Properties of Al-Si-Based Alloys

The effect of bismuth and calcium additions on the microstructural characteristics and the tensile properties of the modified and grain-refined Al-Si based B319 alloys were studied in this paper. Based on the results obtained, it has been concluded that Bi reacts with both Sr and Mg, leading to severe demodification of the eutectic Si at Bi levels of 0.15%-0.6% Bi. Bismuth causes a decrease of ...

SR Ca refilling upon depletion and SR Ca uptake rates during development in rabbit ventricular myocytes

Huang J, Hove-Madsen L, Tibbits GF. SR Ca refilling upon depletion and SR Ca uptake rates during development in rabbit ventricular myocytes. Am J Physiol Cell Physiol 293: C1906–C1915, 2007. First published October 10, 2007; doi:10.1152/ajpcell.00241.2007.— While it has been reported that a sparse sarcoplasmic reticulum (SR) and a low SR Ca pump density exist at birth, we and others have recent...
