Its principal cities are Warsaw (1.783 million) in the centre of the Warsaw metropolitan area, Radom (212,230) in the south, Płock (119,709) in the west, Siedlce (77,990) in the east, and Ostrołęka (52,071) in the north. The voivodeship has an area of 35,579 square kilometres (13,737 sq mi) and, as of 2019, a population of 5,411,446, making it the largest and most populated voivodeship of Poland. The Masovian Voivodeship ( Polish: województwo mazowieckie ), also known as the Mazovia Province, is a voivodeship ( province) in east-central Poland, with its capital located in the city of Warsaw, which also serves as the capital of the country. I’ve spotted CoPErNiCuS (cobalt, phosphorus, erbium, nickel, copper and sulfur), GeNiUS (germanium, nickel, uranium and sulfur) and three different ways of making bacon (BaCoN, BAcON and BaCON).(of which €100.3 billion Warsaw metropolitan area and €30.2 rest of Masovian Voivodeship) I’ve now spent far too long trying to spell out words using the periodic table. ![]() This is the nature of basic research – sometimes you explore at the edges of knowledge.’ That’s a nice lesson for every scientist to take to heart, especially when you’ve spent a long time making an exploratory compound based on a joke in a comedy show. ‘You interview the material by doing measurements and see what it has to offer. In an Chemistry World interview with Tabitha Watson, Paul explained that his team are trying to invent and study brand new materials, so they have to get their inspiration from somewhere. So it’s unlikely to be useful for anything except selling mugs, T-shirts and other merchandise with the chemical formula on it.Īlthough Na Hyun and Paul didn’t inadvertently find a new chemical blockbuster, they’re glad they tried. It isn’t particularly conductive or magnetic, and it doesn’t change structure as the temperature changes either. It doesn’t become a superconductor at low temperatures. But, alas, it was not to be.ĭespite carrying out multiple tests, BaZnGa turned out to have no interesting properties at all. After all, another material containing barium, zinc, gallium and oxygen – known as a barium zinc gallate – is conductive. ![]() And it would have been amazing if a TV catchphrase had inadvertently predicted a major new material. The other sites in green, cyan and blue can be occupied by zinc and galliumīefore Na Hyun and Paul made BaZnGa, nobody knew what it would be like. The crystals are also very sensitive to oxygen, so they need to be carefully handled in an atmosphere of argon or nitrogen. It features identical double layers of octahedrons, each made of layers of zinc and gallium atoms separated by sheets of barium. Looking more closely at the compound, the team discovered that BaZnGa has a crystalline structure unique for any combination of these elements. At the end, Na Hyun was rewarded with plate-shaped crystals of BaZnGa. Finally, they cooled it back down over five days. Then they mixed the resulting material with gallium, stuck it in a sealed silica tube and heated it back up to 800 ☌ for five hours. To make BaZnGa, they heated barium and zinc to 800 ☌ over five hours, kept it there for 12 hours, then cooled it back down to 400 ☌ over a further 12 hours. Talking to the head of her lab, materials scientist Paul Canfield, Na Hyun realised that nobody had tried to make BaZnGa before (or to give it its formal name, barium zinc gallide), and that it might have some interesting properties.
