Three-Dimensional Transmission Electron Microscopy:  A Novel Imaging and Characterization Technique with Nanometer Scale Resolution for Materials Science

Koster, A. J.; Ziese, U.; Verkleij, A. J.; Janssen, A. H.; P. de Jong, K. (2000)
Publisher: Figshare
Three-dimensional transmission electron microscopy (3D-TEM), effectuated by multiple imaging of a sample combined with image analysis, offers a new approach in materials science to obtain 3D information of complex solid materials. Here we report first-of-its-kind results that have been obtained with zeolite materials. Virtual cross-sections and volume rendering of the 3D reconstruction of a metal/zeolite crystal (Ag/NaY) give unequivocal information on the location of the silver p...

Chemistry of Metal-Bound Anion Radicals. A Family of Mono- and Bis(azopyridine) Chelates of Bivalent Ruthenium

Shivakumar, Maya; Pramanik, Kausikisankar; Bhattacharyya, Indranil; Chakravorty, Animesh (2000)
Publisher: Figshare
The reaction of the dihydride [RuII(H)2(CO)(PPh3)3], 3, with excess azo-2,2‘-bipyridine (abp) in boiling dry benzene has afforded the diradical bischelate [RuII(abp•-)2(CO)(PPh3)], 4, and the hydridic monochelate monoradical [RuII(abp•-)(H)(CO)(PPh3)2], 5. A similar reaction between 3 and 2-(p-chlorophenylazo)pyridine (Clpap) did not yield a bischelate, but the hydridic monoradical [RuII(Clpap•-)(H)(CO)(PPh3)2], 6, has been isolated. Upon treatment of 4−6 with NH4PF6 in a wet dich...

Bridged Silver(I) Complexes of the Polycyclic Aromatic Compounds Tetraphenylethylene and 1,1,4,4-Tetraphenyl-1,3-butadiene

Ino, Ichiro; Wu, Liang Ping; Munakata, Megumu; Kuroda-Sowa, Takayoshi; Maekawa, Masahiko; Suenaga, Yusaku; Sakai, Ryusuke (2000)
Publisher: Figshare
For the purpose of investigating the coordination behavior of the sterically congested alkenes and exploring the possibility of cofacial complexation in the polycyclic aromatic system for formation of extended polymeric networks, tetraphenylethylene (tphe) and 1,1,4,4-tetraphenyl-1,3-butadiene (tphb) have been studied with regard to their complexation with a silver(I) ion. The crystal structures of [Ag(tphe)(ClO4)(p-xylene)], [Ag2(tphe)(ClO4)2], [Ag4(tphe)(CF3SO3)4], [Ag2(tphb)(Cl...

United States Biotechnology Study, 1997-1998

Miller, Jon D. (2000)
Publisher: ICPSR - Interuniversity Consortium for Political and Social Research
Fielded November 11, 1997, through February 14, 1998, this study collected data from United States citizens aged 18 and older regarding their interest in and attentiveness to selected current news issues, knowledge of and attitudes toward biotechnology, various forms of political participation, and knowledge of scientific concepts. Conducted not long after the 1996 Eurobarometer Survey (EUROBAROMETER 46.1: MODERN BIOTECHNOLOGY, PRIVACY ON COMPUTER NETWORKS, AND THE COMMON EUROPEAN CURRENCY, O...

Measuring Monetary Policy Inertia in Target Fed Funds Rate Changes

Dueker, Michael (2000)
Publisher: ICPSR - Interuniversity Consortium for Political and Social Research
Recent research has grappled with an apparent paradox: Why would a central bank that is focused primarily on inflation control exhibit signs of inertia when making policy adjustments? In this article, the author argues that fully characterizing the policy inertia is a precondition toward resolving the apparent paradox. This research presents empirical estimates of adjustments to the target fed funds rate that take into account two facets of policy inertia: a partial-adjustment mechanism and t...

Smart Molecular Helical Springs as Tunable Receptors

Jung, Ok-Sang; Kim, Yun Ju; Lee, Young-A; Park, Jong Ku; Chae, Hee K. (2000)
Publisher: Figshare
The rational construction and operation of an ideal helical spring has been investigated. The infinite helices, [Ag(Py2O)]X (Py2O = 3,3‘-oxybispyridine; X- = NO3-, BF4-, ClO4-, and PF6-), have been constructed in high yield via cooperative effects of the skewed conformer of Py2O and the potential linear geometry of the N−Ag(I)−N bond. Crystallographic characterization reveals that the polymer framework is an ideal cationic cylindrical helix and that its counteranions are pinched i...
