The Chinese government is facing fresh accusations of a cover-up after officials deleted crucial online data about the laboratory suspected of being the source of Covid-19.
The Mail on Sunday can reveal that hundreds of pages of information relating to studies carried out by the top-secret Wuhan Institute of Virology have been wiped.
Details of more than 300 studies, including many investigating diseases that pass from animals to humans, published online by the state-run National Natural Science Foundation of China (NSFC) are no longer available.

Abstract:
Diamond is the hardest material in nature. But out of many expectations, it also has great potential as an excellent electronic material. A joint research team led by City University of Hong Kong (CityU) has demonstrated for the first time the large, uniform tensile elastic straining of microfabricated diamond arrays through the nanomechanical approach. Their findings have shown the potential of strained diamonds as prime candidates for advanced functional devices in microelectronics, photonics, and quantum information technologies.

Calcium ions are presented in rocks, bones, shells, biominerals, geological deposits, ocean sediments, and many other important materials. Calcium ions also play major roles in the retention of carbon dioxide in natural waters, water hardness, signal transduction and tissue generation. As one of the alkaline earth metals, the calcium atom has two valence electrons according to the octet rule. Up to now, the only known valence state of calcium ions under ambient conditions is +2, and the corresponding crystals with calcium ions are insulating.
