Phys.org August 6, 2024 China says it launched a rocket Tuesday carrying a constellation of a reported 18 satellites as part of efforts to assert its presence in space. The satellites were carried aboard a Long March-6 carrier rocket from the Taiyuan Satellite Launch Center in north China’s Shanxi Province early on Tuesday afternoon. It has also launched the Beidou System of satellites for national security, communications and scientific purposes, seen as an alternative—or possible competitor—to the GPS system widely used for navigation that is mainly helmed by the United States… read more.

A review of single molecule-based electronic devices
Eurekalert November 21, 2019 At present traditional electronic devices based on semiconductor materials are facing technical, technological limitations and theoretical limitations. Single molecule electronic devices are considered one of the most hopeful candidates. Researchers in China provide an overview of single molecule electronic devices, including molecular electronic devices and electrode types. Several molecular electronic devices are presented, including molecular diodes, molecular memories, molecular wires, molecular field effect transistors (FET) and molecular switches. The influence of different electrode types of the transport characteristics and other characteristics of molecular devices are briefly introduced, such as potential thermoelectric effects. The future challenges to […]
