The oxygen permeability through the grain boundaries of Hf- and/or Lu-doped polycrystalline alumina wafers that were exposed to oxygen potential gradients generated by combinations of different oxygen partial pressures ( P O 2 ) was investigated at t

Apoptosis in Xenopus egg extracts is carried out by maternally stockpiled materials, but the contributions of endogenous apoptosis regulators are still poorly characterized. Here we examined the physiological role of Xenopus Bid (xBid), a pro-apoptot

Electrical properties of Si-implanted n-type GaN/AlGaN/GaN layers and contact resistances of ohmic electrodes (TiAl) formed on these layers have been examined. Experimental results have clearly shown that ohmic electrodes with a low specific-contact

Ni-doped γ-Al2O3 with different molar compositions has been synthesized on α-Al2O3 porous supports by the sol-gel method using nitrate-alkoxide precursors. The increasing of lattice constants by Ni doping showed the formation of uniform solid solut

Purpose The viability of mammalian eggs after ovulation is reported to be improved by the presence of ascorbic acid in the culture medium. However, the pro-survival mechanisms of ascorbic acid are poorly understood. The molecular pathways of apoptosi

Helium‐permselective silicon carbide (SiC) membrane was successfully synthesized on an outer surface of γ‐alumina‐coated α‐alumina porous support by both pyrolysis of polycarbosilane without oxygen‐curing process and chemical vapor infilt

Mechanical tests and microstructural investigations were performed on porous cordierite ceramics. Four-point bending tests were carried out both in air and in water. It was shown that the mechanical strength was strongly influenced by the experimenta

Neoplastic cells from human esophageal cancer cell lines, SGF-3, SGF-4 and SGF-5, maintained in a hypothermic state at 21.5°C were examined under electron microscope. Ultrastructural alterations, including nucleolar lesions, were found in the cells.
