Cuban researchers

Rosa Llusar was born on September 20th, 1960 in Almenara (Spain). She studied chemistry at the University of Valencia (Spain) where she graduated in 1983 with the highest honors. Her doctorate work was devoted to the chemistry of cubane-type molybdenum and tungsten sulfides and she received Ph.D. degrees from Valencia University in 1987 and from Texas A M University (USA) in 1988, under the guidance of Prof. F. Albert Cotton. After working in the Research and Development Department of a Caprolactam Production Plant in Castello (Spain) for three years, she spent one year (1992) with Prof John D. Corbett at the... 

Amino acid is one of the most important biological ligands. Researches on the coordination of metal-amino acid complexes will help us better understand the complicated behavior of the active site in a metal enzyme. Up to now many Ln-amino acid complexes [50] and 1 1 or 1 2 transition metal-amino acid complexes [51] with the structural motifs of mononuclear entity or chain have been synthesized. Recently, a series of polynuclear lanthanide clusters with amino acid as a ligand were reported (most of them display a Ln404-cubane structural motif) [52]. It is also well known that amino acids are useful ligands for the construction of polynuclear copper clusters [53-56], Several studies on polynuclear transition metal clusters with amino acids as ligands, such as [C03] [57,58], [Co2Pt2] [59], [Zn6] [60], and [Fe ] [61] were also reported. 

The authors are grateful to Profs. Alan Marchand and Philip Eaton for supplying with samples of AEBCB and cubane, respectively. This work has been supported by the Mechanics and Energy Conversion Division of the Office of Naval Research. 

Nitrocubanes are probably the most powerful explosives with a predicted detonation velocity of >10,000 ms-1. Cubanes were first synthesised at the University of Chicago, USA by Eaton and Cole in 1964. The US Army Armament Research Development Centre (ARDEC) then funded development into the formation of octanitrocubane [(ONC) (C8N8016)] and heptanitrocubane [(HpNC) (C8N7014)]. ONC and HpNC were successfully synthesised in 1997 and 2000 respectively by Eaton and co-workers. The basic structure of ONC is a cubane molecule where all the hydrogens have been replaced by nitro groups (1.6). HpNC is denser than ONC and predicted to be a more powerful, shock-insensitive explosive.

Out of the debate over the use of technology in education has risen the idea that technology is not an end unto itself (Cuban 2001) but a means to reach other ends more efficiently. In this chapter, we examine a situation where technology facilitated student exposure to applied research in physical chemistry and advanced instrumentation. 

Examples which come to mind are those of Philip E. Eaton, who owed his interest in cage molecules to industrial work on chlorinated pesticides, which led him to the epochal synthesis of cubane in 1964 (Traynham 1997) of Fred McLafiferty and George Olah, who both worked for a time in a laboratory of Dow Chemical of Richard E. Smalley, an industrial chemist before he enrolled as a graduate student at Princeton (Smalley 1996) of Earl Muetterties, who left the Experimental Station at DuPont in Wilmington for a professorship at the University of California of Howard E. Simmons who, when heading central research also at DuPont, turned down the offer of a professorship at Harvard (Bohning 1993, Roberts Collette 1999) and so on.

This book is very unusual in the field of organization studies because it is a collaborative effort to dissect a decision-making situation from many perspectives. The nearest forerunners are probably Allison and Zelikow s (1999) book on the Cuban missile crisis and Moss and Sills et al. s (1981) book about the accident at Three Mile Island, which also used multiple lenses to interpret single chronologies of events. Overall, there are almost no examples of organizational research that bring... 

The atmospheric research stations on materials from different kinds, may be use to evaluate the behavior of previously conceive and elaborated materials when they are under the aetion of the aggressive agents from the Cuban climate. These stations are useful for the seleetion of new protecting systems to prevent the aging process on different materials and also to confirm the validity of the results obtained during the researches recommended to cany out.
