A BBC report on the August 2017 American Chemical Society meeting states ‘Cyborg’ bacteria deliver green fuel source from sunlight. To summarise, some bacteria deal with heavy metals such as cadmium by converting it to cadmium sulphide semiconductor crystals on their surfaces. These bacteria are then able to convert carbon dioxide + water + light into acetic acid with high efficiency.

International Union of Pure and Applied Chemistry (IUPAC) have confirmed the names of elements 113, 115, 117, and 118 as:

  • Nihonium and symbol Nh, for element 113
  • Moscovium and symbol Mc, for element 115
  • Tennessine and symbol Ts, for element 117
  • Oganesson and symbol Og, for element 118

This followed a 5-month period of public review after which the names earlier proposed by the discoverers were approved by IUPAC.

A panel commentary in Nature Chemistry Commentary speculates upon the names that might be proposed for the four new elements in the periodic table. Worth a read, but we’ll have to wait a while longer yet.

Abstract: “Of all the things humans can bestow names upon, new chemical elements are about the rarest. Our group of periodic table experts attempts to read the tea leaves and predict the names for elements 113, 115, 117 and 118.”

The International Union of Pure and Applied Chemistry (IUPAC) has provisional recommendations for the naming of new elements and the recommendations are open for comment until 29 February 2016.

IUPAC state “the most important change is that the names of all new elements should have an ending that reflects and maintains historical and chemical consistency. This would be in general “-ium” for elements belonging to groups 1-16, “-ine” for elements of group 17 and “-on” for elements of group 18.”

The discoverers have the right to suggest names and symbols.

The International Union of Pure and Applied Chemistry (IUPAC) announced IN January 2016 that the identification of the four new elements with atomic numbers 113, 115, 117, and 118 is verified and that the discoverers of elements 113, 115, 117, and 118 are invited to suggest names.

Element 113 has a temporary working (systematic) name and symbol: ununtrium, Uut. It was discovered by the RIKEN collaboration team in Japan who fulfilled the criteria for element Z=113.

The media cover a story that scientists at the German Max Planck Institute produced a helium plasma contained for about a tenth of a second but at about 1000000 K. The next step at the Wendelstein 7-X (a stellarator fusion reactor) is to increase the stability of the plasma, to improve the heating method, and to increase the plasma temperature.
