A group of South Korean scientists has developed a new material to effectively block electromagnetic waves emanating from electronic gadgets and appliances, Yonhap news agency reported.The team led by Gu Jong-min of the Korea Institute of Science and Technology (KIST) and a research team of Drexel University in the US successfully manufactured the material made out of Mxene.Mxene is a class of two-dimensional inorganic compounds made out of titanium and carbon and a single layer is only about one nanometer.The team discovered that Mxene can block the electromagnetic waves from mobile phones, televisions, microwave ovens and other appliances, scientists said, noting that the material is easy to process and the cost is relatively cheap."It is hoped that the developed material can be used not only to block electromagnetic waves but for other various purposes," Gu said.The research was published in the journal Science.
