MIT Professor Gang Chen accused of hiding millions in foreign money to advance People’s Republic of China’s scientific, technological goals
Updated Jan 14, 2021;
A Massachusetts Institute of Technology professor was arrested Thursday in connection with a wide-reaching scheme in which he is accused of abusing federal grant money and receiving millions from the Chinese government to advance the nation’s scientific and technological goals, authorities said.
Gang Chen, a 56-year-old professor and researcher at MIT, is accused of failing to disclose millions of dollars worth of contracts, appointments and awards from various entities in the People’s Republic of China to the United States Department of Energy, according to U.S. Attorney Andrew Lelling.
A Massachusetts Institute of Technology (MIT) professor was arrested Thursday and charged with secretly working for China's technology collection programs and failing to disclose the work to the Energy Department.
A Nanomechanical Approach for Stretching Microfabricated Diamonds
Written by AZoNanoJan 4 2021
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.
The research was co-led by Dr Lu Yang, Associate Professor in the Department of Mechanical Engineering (MNE) at CityU and researchers from Massachusetts Institute of Technology (MIT) and Harbin Institute of Technology (HIT).
Heat provides a simple way to separate entangled electrons for research
The thermoelectric effect can be used to produce entangled electrons, according to scientists from Finland, Russia, China and the USA.
The proof-of-concept device is based on superconductivity, and combines a patterned single-layer graphene sheet (green) and metal (blue) electrodes on a silicon dioxide substrate (grey).
Superconductivity is caused by entangled pairs of electrons called Cooper pairs. These pairs enter through one electrode in the device and leave separately through two more (see photo and below), split by a temperature difference. “The resulting electrons remain entangled despite being separated for quite long distances,” said researcher Nikita Kirsanov of Aalto University in Finland.
