The once bright orange yellow parts of the sky have faded to off white.Similarly, in his painting "The Joy of Life", Henr...
It is reported that the research team of California Institute of Technology has developed an additive manufacturing (AM) technology based on hydrogel injection, which uses two-photon lithography technology to produce 3D metal with a characteristic resolution of about 100 nm.The relevant research is published in the journal Nano Letters, titled 'Suppressed Size Effect in Nanopillars with Hierarchy ...
Laser soldering is widely used in the manufacturing of automotive parts. Here are some common automotive parts that can be welded using laser soldering:Automotive electronic control systemEngine Control Unit (ECU): The engine control unit is the "brain" of the car engine, which receives signals from various sensors and controls the operation of the engine based on these signals. Laser soldering ca...
The team of Wu Dong, professor of the Micro/Nano Engineering Laboratory of University of Science and Technology of China, proposed a processing strategy of femtosecond laser two in one writing into multiple materials, manufactured a micromechanical joint composed of temperature sensitive hydrogel and metal nanoparticles, and then developed a multi joint humanoid micromachine with multiple deformat...
Researchers from the Laser Energy Laboratory at the University of Rochester led the experiment and demonstrated an efficient "spark plug" for direct driving of inertial confinement fusion. In two studies published in the journal Nature Physics, the team shared their findings and detailed the potential to expand these methods with the aim of successful nuclear fusion in future facilities.LLE is the...
