Tangerang -- Approximately at Thursday 10pm (02/08) The Indonesia Chemistry Olympiad arrived at Soekarno-Hatta International Airport after finished their job at 44th  International Chemistry Olympiad (IChO) that is held from 21st-30th July at Washington, D.C., United States. For the 16th times Indonesia sent the delegatin which reprensented by:

The triple bonded boron compound is stable at room temperature Carbon and nitrogen are well known for their triple bonds, but making stable compounds with a triple bond between two boron atoms hadn’t been achieved despite the computational possibilities. Until now. Holger Braunschweig of the Institute for Inorganic Chemistry at Julius-Maximilians-Universität in Würzburg, Germany, and colleagues found that reacting a bis( N -heterocyclic carbene) stabilised tetrabromodiborane with either two or four equivalents of sodium naphthalenide, a single electron reducing agent, generates a diborene or diboryne compound, which they isolated and characterised. Their analysis confirms a linear, halogen-free compound with a boron-boron triple bond. 1

IUPAC has officially approved the name flerovium, with symbol Fl, for the element of atomic number 114 and the name livermorium, with symbol Lv, for the element of atomic number 116. Priority for the discovery of these elements was assigned, in accordance with the agreed criteria, to the collaboration between the Joint Institute for Nuclear Research (Dubna, Russia) and the Lawrence Livermore National Laboratory (Livermore, California, USA). The collaborating team has proposed the names flerovium and livermorium which have now been formally approved by IUPAC.

Some 300 million years later, the very first stars emerged, creating additional chemical elements throughout the universe. Since then, giant stellar explosions, or supernovas, have given rise to carbon, oxygen, iron and the rest of the 94 naturally occurring elements of the periodic table.

DOI: 10.1002/chemv.201000151 Author: Javier Garcia Martinez Published Date: 03 December 2011 Copyright: WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim On the first day of the last month of the International Year of Chemistry , young chemists, professionals, educators, policy makers, and even a Nobel Prize winner and a crowned prince joined in the Square Brussels Meeting Centre to celebrate the many accomplishments of the International Year of Chemistry (IYC).

At the Closing Ceremony of the International Year of Chemistry in Brussels on December 1st 2011 the President of the International Union of Pure and Applied Chemistry (IUPAC), Professor Nicole J. Moreau, announced the proposed names for the elements with atomic numbers 114 and 116.

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry for 2011 to: Daniel Shechtman Technion - Israel Institute of Technology, Haifa, Israel "for the discovery of quasicrystals"
