Ethanol/benzyl alcohol mixtures are effective thermal stabilizers for jet fuels above 400°C. Ethanol, which itself is only a marginal thermal stabilizer, primarily serves to regenerate benzyl alcohol in situ by reducing benzaldehyde, the reaction product formed by the reaction of benzyl alcohol with the hydrocarbon radicals produced at these temperatures. Accordingly, in the presence of ethanol, less benzyl alcohol is necessary to thermally stabilize hydrocarbon fuels under the same conditions of time and temperature.

Electronic properties of radiation damage produced in 4H–SiC by neutron irradiation and its effect on electrical parameters of Junction Barrier Schottky (JBS) diodes were investigated. 4H–SiC N-epilayers, which formed the low-doped N-base of JBS power diodes, were irradiated with 1 MeV neutrons with fluences ranging from 1.3 × 1013 to 4.0 × 1014 cm−2. Radiation defects were then characterized by capacitance deep-level transient spectroscopy, I–V and C–V measurement. Results show that neutron irradiation introduces different point defects giving rise to acceptor levels lying 0.61/0.69, 0.88, 1.03, 1.08 and 1.55 eV below the SiC conduction band edge. Introduction rates of these centers are ranging from 0.64 to 4.0 cm−1. These defects have a negligible effect on blocking and dynamic characteristics of irradiated diodes. However, the acceptor character of introduced deep levels and their fast introduction deteriorate diode’s ON-state resistance already at fluences exceeding 1 × 1014 cm−2.

Natural quartz and natural calcite were irradiated with fast neurons. Radiation effects caused structural distortion in quartz and produced color centers in calcite.

Medical Roads Lead to New Hospital in Rome

ON THE OUTSKIRTS of Rome, three starkly modern buildings house a comprehensive medical facility whose concept and operation contrast as much with usual public-sector Italian health care as sleek architecture does with antiquities of city center. Rome American Hospital was opened as a profit-making venture by a group of Italian investors in May 1990, because of what Charles W. Neumann, an American and its chief executive officer, calls the pressing demand for private health care in Italy. It's ironic, isn't it? Neumann asks. Every European country that has a very large national health care commitment is looking for ways to reduce that commitment or shift it a bit more to private sector. And in United States, you're looking at just opposite. Neumann was managing director of European division of Hospital Corporation of America Inc, which planned Rome facility then turned
