Cornell researchers have topped their own record for atomic resolution with an electron microscope pixel array detector that incorporates sophisticated 3D reconstruction algorithms. ....
Cornell University Cornell researchers have created micron-sized shape memory actuators that enable atomically thin two-dimensional materials to fold themselves into 3D configurations. Self-folding nanotech creates world’s smallest origami bird March 17, 2021 If you want to build a fully functional nanosized robot, you need to incorporate a host of capabilities, from complicated electronic circuits and photovoltaics to sensors and antennas. But just as importantly, if you want your robot to move, you need it to be able to bend. Cornell researchers have created micron-sized shape memory actuators that enable atomically thin two-dimensional materials to fold themselves into 3D configurations. All they require is a quick jolt of voltage. And once the material is bent, it holds its shape – even after the voltage is removed. ....
