Element 114 is Named Flerovium and Element 116 is Named Livermorium

May 31st, 2012

The formal announcement by IUPAC regarding new elements 114 and 116 was
officially released today 31 May 2012 at 09:00 Eastern Daylight Time in
the USA. A copy of the IUPAC Press Release is attached.

114_116Extract from the new 8th Edition (2012) of the Karlsruhe Nuclide Chart showing the isotopes of flerovium and livermorium.

These new names will be included in the new 8th Edition of the Karlsruhe Nuclide Chart which will be published shortly.

New version of the Universal Nuclide Chart released

May 7th, 2012

The Universal Nuclide Chart (UNC) is a web-based nuclide chart in Nucleonica. In contrast to Nucleonica’s Nuclide Explorer (which provides comprehensive nuclear data), the UNC allows the user to simulate radioactive decay processes and actinide build-up in reactors through transmutation. This new version of the application is based on the JEFF3.1 radioactive decay data. The older version of the application was based on the earlier JEF2.2 data.

New version of Nucleonica’s Decay Engine released

May 7th, 2012

A new version of the Decay Engine – one of the most popular tools in Nucleonica – has been released. The application has been streamlined to improve the user-friendliness and ease of operation. There are now two modes of operation which can be selected in the Options:
1. Time mode: For an initial activity of a given nuclide or mixture, the final activity is calculated after a decay time.
2. Date mode: if a activity is known at some time (date), then the activity can be calculated at any other time (date). In this date mode, the user can enter a date (e.g. when the sample was taken). The calculation result then shows the activity at any later time (date). This is useful for the calculations of standards.

Other new features include: use of a slider control for easy reading of graphs, easier selection of nuclides or groups of nuclides for plotting; activation of features to be shown in the main tab; selection of quantities to be shown in the grid output; new decay “tree” manifestation of the decay processes.
