MIT professor Gang Chen was at his home in Cambridge on a Thursday morning when he was met by the police, there to arrest the engineer over claims that for years he had hid illicit ties to the People’s Republic of China.
New Flexible Crystal may Lead to More Efficient Bendable Electronics

Headed by Nanyang Technological University, Singapore (NTU Singapore), a research team has designed a novel material that can flex and bend 40 times more than its competitors when an electric current is applied on it, paving the way to more improved micro machines.

On the other hand, when the new material is bent, it produces electricity quite effectively and can perhaps be utilized for more improved energy harvesting possibly recharging batteries in gadgets simply from everyday movements.

A team of researchers led by Nanyang Technological University, Singapore (NTU Singapore) has developed a new material, that when electricity is applied to it, can flex and bend forty times more than its competitors, opening the way to better micro machines.
Conversely, when it is bent, it generates electricity very effectively and could be used for better energy harvesting - potentially recharging batteries in gadgets just from everyday movements.

Late this January, the University of Pennsylvania’s president, Amy Gutman, got a second letter from Congress about China’s million-dollar donations there. The campus is home to the Biden Center for Diplomacy and Global Engagement, or “the Biden Center.” It was launched in 2017, after which Chinese gifts more than tripled from $21 million over 36 months before 2017 to more than $72 million during a similar time-frame after.
Signed by Jim Jordan, James Comer, and Virginia Foxx of the House Judiciary, Oversight and Education committees, the letter explained:
In light of your university’s close relationship with the Biden family, and recent revelations regarding their potentially illicit ties to foreign adversaries including China, we request an immediate response to this inquiry.

Singapore, February 8 (ANI): A team of researchers from Nanyang Technological University, Singapore (NTU Singapore), have developed a new material that can flex and bend forty times more than its competitors when electricity is applied to it. This discovery will open the way to better micro machines.
Conversely, when it is bent, it generates electricity very effectively and could be used for better energy harvesting - potentially recharging batteries in gadgets just from everyday movements.
The novel material is both electrostrictive and piezoelectric. Its electrostrictive properties mean it can change shape when an electric current is applied, while piezoelectric means the material can convert pressure into electric charges. The findings were published in the scientific journal Nature Materials.
