text: “The chemistry community is eager to see its most cherished table finally being completed down to the seventh row. IUPAC has now initiated the process of formalizing names and symbols for these elements temporarily named as ununtrium, (Uut or element 113), ununpentium (Uup, element 115), ununseptium (Uus, element 117), and ununoctium (Uuo, element 118)” said Professor Jan Reedijk, President of the Inorganic Chemistry Division of IUPAC.
  The proposed names and symbols will be checked by the Inorganic Chemistry Division of IUPAC for consistency, translatability into other languages, possible prior historic use for other cases, etc. New elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist (see: W.H. Koppenol, PAC, 74 (2002) 787-791). After Divisional acceptance, the names and two-letter symbols will be presented for public review for 5 months, before the highest body of IUPAC, the Council, will make a final decision on the names of these new chemical elements and their two-letter symbols and their introduction into the PeriodicTable of the Elements.
  “As the global organization that provides objective scientific expertise and develops the essential tools for the application and communication of chemical knowledge for the benefit of humankind, the International Union of Pure and Applied Chemistry is pleased and honored to make this announcement concerning elements 113, 115, 117, and 118 and the completion of the seventh row of the periodic table of the elements,” said IUPAC President Dr. Mark C. Cesa, adding that, “We are excited about these new elements, and we thank the dedicated scientists who discovered them for their painstaking work, as well the members of the IUPAC/IUPAP Joint Working Party for completing their essential and critically important task.”
  
  Equistix filter membrane is a thin polymer films composed of millions of microscopic pores that is recommended for retaining small particles and microorganisms on the surface of the
  membrane by acting as a physical barrier. They are used to sterilize liquid reagents, remove particulate contamination and clarify solutions prior to further processing.
  Nylon membrane filters are hydrophilic in nature and chemically resistant to most bases, making them suitable for clarification and sterilization of alkaline solutions.
  Nylon membrane is also compatible with most aqueous samples and some organic solvents and is a good alternative for sterilization and clarification of the mobile phases used for HPLC.
  Nylon membranes have high non-specific adsorption, which are very useful in blotting techniques, especially for the transfer and immobilization of nucleic acids.
