Demand for electronic materials such as tungsten and rare earths exceeded more than 110 billion US dollars per year globally in recent years, according to the Industrial Research Institute (ITRI) of Taiwan. It is expected that with the advent of the 5G and IAOT era the development of the electronic materials industry will be boosted.

Victoria releases more land for exploring gold, lithium and rare earths. According to the miningweekly.com, Australia's Victorian Minister for Resources Jaclyn Symes announced last Tuesday that it would open up more land in the North Central Victorian Goldfields to mining companies that could demonstrate a commitment of engaging with traditional owners and which would boost local employment.

Besides holding rare earths, China owns another invaluable resource with a monopoly position which is merely available - the rare earth magnets. They are super-strong permanent magnets. Nowadays, most of the electronic products use these materials. As the US is a big technology country, permanent magnets have a huge impact in the country. To some extent, the rare earth magnets are even more important than rare earths for the US.

Scientists all over the world have been trying to break through the structural improvement of graphene materials. Recently, two researchers from the University of Kansas in the United States connected the graphene layer with two other transition metal monolayer two-dimensional materials -- Molybdenum selenide and tungsten disulfide, thus prolonging the electronic life cycle and stimulating the electronic efficiency of graphene hundreds of times. The significance of this work is to promote the high-performance ultra thin solar cells and flexible solar cells development.
