Tianbo Yu comes from Tsinghua University in Beijing a leading university within technical scientific research. His studies in Denmark have been financed by the Danish National Research Foundation, which also supports a Danish-Chinese basic research centre in the Materials Research Division, where Tianbo Yu is now employed.
Tianbo Yu is a dedicated and talented researcher, who wishes to pursue a research career in Denmark. His wife is a student at RU (Roskilde University) and along with their studies, they both have decided to put a lot of effort into learning Danish; and they have become good at it. All in all, a success for science as well as globalisation.
Smaller metal grains result in stronger metals
Nanometals contain very small metal grains - from 10 to 1,000 nanometers. One nanometer is a millionth of a millimetre. The smaller the metal grains become, the stronger the metal becomes. The metal becomes twice as strong, for example, if the individual metal grains are made four times smaller. That is why the materials scientists work to reduce the size of the individual metal grains. In steel and aluminium, the particles have been reduced to below 1 micrometre, which is one thousandth of a millimetre. There is a great interest in nanometals worldwide. Nanometals are super strong and their super strength can be combined with other desired properties, too.
A good example of a super strong nanometal is the thin steel wires used in grand pianos and for strengthening lorry tyres and containers, which have to withstand an extremely high pressure. A
