A joint IUPAC/IUPAP Working Party (JWP) has confirmed the discovery of the element with atomic number 112. In accord with IUPAC procedures, the discoverers proposed a name, copernicium, and symbol, Cn, for the element. The IUPAC Inorganic Chemistry Division Committee recommended this proposal for acceptance, and it has now been approved by the IUPAC Bureau as delegated to act by the IUPAC Council meeting on 12 August 2007.
Valentin Koptyug (1931–1997) was President of IUPAC during the 1987/89 biennium. In addition to his immense service to the educational, scientific and economic development of his own country Professor Koptyug made outstanding contributions to IUPAC over many years as well as to the other international organisations which he served. His interest in and dedication to the preservation of the environment and to the principles of sustainable development came very early. As a consequence, his influence has extended over many years. His inspiration has motivated IUPAC to greatly broaden the scope of its work and to collaborate with other international organisations to tackle real problems of societal interest.
A joint IUPAC–IUPAP Working Party (JWP) confirmed the discovery of the element with atomic number 110. In accord with IUPAC procedures, the discoverers proposed a name and symbol for the element. The Inorganic Chemistry Division recommended this proposal for acceptance, and it was adopted by the IUPAC Council at Ottawa, 16 August 2003. The recommended name is darmstadtium with symbol Ds.
A joint IUPAC-IUPAP Working Party (JWP) confirmed the discovery of element number 111. In accord with IUPAC procedures, the discoverers proposed a name and symbol for the element. The Inorganic Chemistry Division recommended this proposal for acceptance, and it was adopted by IUPAC on 1 November 2004. The recommended name is roentgenium with symbol Rg.
A joint IUPAC/IUPAP Working Party (JWP) has confirmed the discovery of the
elements with atomic numbers 114 and 116. In accordance with IUPAC procedures,
the discoverers proposed names as follows: flerovium with the symbol Fl for the
element with Z = 114 and livermorium with the symbol Lv for the
element with Z = 116. The IUPAC Inorganic Chemistry Division
recommended these proposals for acceptance, and they were adopted on 23 May 2012
by the IUPAC Bureau as delegated to act by the IUPAC Council meeting on 3–4
The procedures to be followed in the naming of new elements fall into two distinct phases. The first of these is done jointly between IUPAC and the International Union of Pure and Applied Physics (IUPAP) and involves the validation of a claimed discovery and its assignation to a laboratory or to a collaborating group of laboratories. The second phase is carried out by IUPAC alone, which utilises its standard procedures for the recommendation of a suitable name. After this recommendation has successfully gone through the usual stringent refereeing processes, it is then finally approved by the Council before being formally announced.
As the world economy continues to return, if somewhat haltingly, to a more vibrant state, it is good to be able to report that during the past twelve months there have been significant and beneficial changes in all aspects of the financial management and operation of the Union. It goes without saying that it has not been possible for IUPAC to emerge completely unscathed from the very difficult financial conditions that have prevailed during and since the recession, but we have come through these circumstances very well. More importantly, we have now set the foundations in our revenue generation and financial management information systems and expenditure controls that will enable us to progress and prosper in the future. The Executive Director and Secretary General have worked this year to bring the management accounting for all operations in-house and the Secretariat is now using new GAAP-compliant software. The recent appointment of a financial controller will ensure that our management accounting is undertaken in a much more timely manner.
Synopsis: This document provides definitions of terms and processes which are used in describing the migration of host and foreign species through solid materials. Both the phenomenological theory of diffusion and the detailed atomistic mechanisms by which atom transport occurs are treated. Also included are the various types of gradients such as electrical, chemical, thermal and mechanical, which provide the driving forces for diffusion.
