Two photon polymerization is a potential method for nanofabrication of integrated nanomaterials based on femtosecond laser technology. The challenges faced in the field of 3D nanoprinting include slow layer by layer printing speed and limited material selection due to laser material interactions.In a new report in Progress in Science, Chenqi Yi and a team of scientists in the fields of technical s...
The application of laser technology has revolutionized the methods of nitrogen fixation, providing a new method for synthesizing ammonia under environmental conditions. Recently, researchers have used commercial carbon dioxide lasers for the first time to disrupt the nitrogen nitrogen triple bond, providing a new green alternative to the Haber Bosch process.It is reported that the international re...
Shijia Photon disclosed its 2024 annual performance forecast on the evening of January 17th, expecting to achieve a revenue of 1.074 billion yuan in 2024, a year-on-year increase of 42.36%; Net profit attributable to the parent company was 65 million yuan, with a loss of 47.55 million yuan in the same period last year; Deducting non net profit is expected to be 48.1 million yuan, with a loss of 66...
Petrobras announced last week that it plans to use laser beams to measure wind speed and direction. The idea is that these data will be used to improve the operation of the wind turbines maintained by this state-owned company in North Rio Grande do.The total investment of the 2.0 version of this device reaches R $11.3 million, known as the offshore wind assessment remote buoy.This technology can a...
A team of researchers at the Fraunhofer Institute for Optoelectronics, Systems Technology and Image Development and Karlsruhe Institute of Technology are using single-photon avalanche diode (SPAD) arrays to achieve three-dimensional (3D) quantum ghost imaging.The new method, called "asynchronous detection," produces the lowest photon dose of any measurement and can be used to image light-sensitive...
