Significantly improved dehydrogenation of LiBH4destabilized by TiF3

Significantly enhanced dehydrogenation properties of calcium borohydride combined with urea.

The interaction of [BH(x)]- and [NH(x)]-containing species gives rise to molecular hydrogen and the establishment of the B-N bond. Up to now, metal amides and ammonia are the commonly used [NH(x)] sources. Herein, urea, an organic carbonyl diamide, was used to react with Ca(BH4)2. A new type of complex hydride Ca(BH4)2·4CO(NH2)2 was synthesized with release of ca. 5.2 wt% hydrogen below 250 °C.

Improved Dehydrogenation Properties of 2LiNH2-MgH2 by Doping with Li3AlH6

Doping with additives in a Li-Mg-N-H system has been regarded as one of the most effective methods of improving hydrogen storage properties. In this paper, we prepared Li3AlH6 and evaluated its effect on the dehydrogenation properties of 2LiNH2-MgH2. Our studies show that doping with Li3AlH6 could effectively lower the dehydrogenation temperatures and increase the hydrogen content of 2LiNH2-MgH...

GEODON significantly improved positive symptoms as measured by BPRS

‡Data are a pooled analysis of all 3 fixed-dose GEODON arms (40 mg/day, 80 mg/day, and 160 mg/day) vs placebo. †“Probability of being relapse-free” was measured by time to impending relapse, which was defined as Clinical Global Impression of Improvement (CGI-I) score of ≥6 or a score of ≥6 on PANSS items P7 (hostility) or G8 (uncooperativeness) on 2 successive days; or, discontinuation due to l...

Significantly improved lifetime of Microchannel Plate PMTs∗

The main particle identification devices of the PANDA experiment will be two DIRCs placed around (barrel) and downstream (disc) of the target. The preferred photon sensor option are microchannel plate (MCP) PMTs because they can be operated inside the 2 Tesla magnetic field of the solenoid. Furthermore, these multi-anode sensors are rather compact and show a superior time resolution which is ty...
