In chemistry , a dihydrogenbond is a kind of hydrogen bond , an interaction between a metal hydride bond and an OH or NH group or another proton donor. The first example of this phenomenon is credited to Brown and Heseltine. ref Cite journal issue 23 pages 1551 1552 last Brown first M. P. coauthors R. W. Heseltine title Co ordinated BH3 as a proton acceptor group in hydrogen bonding journal Chemical Communications London accessdate 2009 04 29 date 1968 doi 10.1039 C19680001551 ref They observed intense absorptions in the IR spectroscopy IR band s at 3300 and 3210 cm sup 1 sup for a solution of CH sub 3 sub sub 2 sub NHBH sub 3 sub . The higher energy band is assigned to a normal N H vibration whereas the lower energy band is assigned to the same bond, which is interacting with the B H. Upon dilution of the solution, the 3300 cm sup 1 sup band increased in intensity and the 3210 cm sup 1 sup band decreased, indicative of intermolecular association. Interest in dihydrogen bonding was reignited upon the crystallographic characterization of the molecule ammonia borane H sub 3 sub NBH sub 3 sub .

Made in 1918 with Edna Purviance , Albert Austin and Sydney Chaplin , the film has a distinctive visual motif set in a simple plain black set with starkly lit simple props and arrangements. The story is a series of sketches humorously illustrating various bonds like the bond of friendship and of marriage and, most important, the Liberty Bond, to knockout K.O. the Kaiser which Charlie does literally.

About the BOND database software Bond disambiguation Bond orphan date June 2010 BOND Building Object Network Databases started development in late 2000 as a rapid application development tool for the GNOME Desktop by Treshna Enterprises . Its aim was to fill a gap that traditional Microsoft Windows applications like Borland Delphi , Microsoft Access and Visual Basic filled on the Windows desktop, but targeted for the Linux environment. Its goal was to allow developers to quickly build database forms in Extensible Markup Language XML for backend SQL databases. It has been employed extensively by Treshna Enterprises to develop applications such as PayMaster an opensource payroll application and GymMaster a commercial gym management application . Description It uses PostgreSQL as its backend database and GTK as its front end. Windows and HTML driven front ends are also available. While it initially worked closely with Glade Interface Designer Glade and the Gnome Desktop, newer versions have focused on more web oriented with Ajax programming AJAX driven Widget computing widgets . The Glade Extensible Markup Language XML format was abandoned a number of years ago and a new XML schema was developed to be more flexible with the range of data required for storing database information. BOND makes use of BONDDB which serves as a layer between the BOND API and the PostgreSQL backend. In the future, BOND aims to be a free open source solution that allows users to quickly create their own databases from scratch without being a skilled programmer or DBA.
