A whole new generation of superconductors, so needed in many high-tech industries, will be based on palladium compounds, scientists believe, and this may be beneficial for Russia, which boasts the world’s reserves of this rare and expensive metal, as well as almost half of its production. Zero resistance In 1911, Dutch physicist Heike Kamerlingh Onnes discovered that the electrical resistance...
Scientists from the Institute of Laser and Welding Technologies of the St. Petersburg State Marine Technical University (SMTU, or ‘Korabelka’) developed a multilayer material using direct laser growth, which will allow parts to withstand dynamic loads longer. The study was published in the International Journal of Advanced Manufacturing Technology. Why it matters The new material will be useful in the...
Scientists at the US-based Sandia National Laboratory, in collaboration with the Ames National Laboratory, the Iowa State University, and Bruker Corp. used a 3D printer to create a high-performance metal superalloy with an unusual composition that makes it stronger and lighter than modern materials currently used in gas turbine equipment, the Sandia lab announced. Experiments showed that a new superalloy...
Minnesota state Sen. Grant Hauschild told WTIP yesterday that he has received confirmation from Cleveland-Cliffs that the mining company is beginning to contact miners about reopening their Babbitt and Silver Bay plants in early April. Northshore Mining operates an open pit taconite mine in Babbitt and a processing plant in Silver Bay along the North Shore of Lake Superior in...
Cooper Metals Ltd (ASX:CPM) is back on the ground at the new Ardmore tenement within the Mt Isa East Copper-Gold Project in north-western Queensland, conducting reconnaissance geochemical sampling. The new work follows the identification of high-grade copper-gold rock chips in November last year, when the company reported assays of up to 17.3% copper and 0.4 g/t gold from a northeast...
The Democratic Republic of Congo (DRC) is working to transform itself from a producer to a processing country, according to Finance Minister Nicolas Kazadi. To achieve this goal, the government has signed a deal with the United Arab Emirates to buy all gold produced by the artisanal sector and is putting infrastructure in place to formalise the market. Most of...
