Recently, a team led by Gao Chunqing and Fu Shiyao from the School of Optoelectronics at Beijing University of Technology combined optical spatial coordinate transformation with photon spin Hall effect to construct a photon angular momentum filter for the first time internationally, achieving on-demand regulation of photon spin angular momentum and orbital angular momentum.The related achievements...
According to reports, the Linac Coherent Light Source II (LCLS-II) X-ray laser at the Stanford SLAC National Accelerator Laboratory in the United States has just completed an upgrade that took more than a decade. After a facelift, it has become the world's brightest X-ray facility and emitted the first record breaking X-ray, allowing researchers to record the behavior of atoms and molecules in bio...
Surface acoustic wave technology is renowned for its high precision and fast driving, which is crucial for microfluidics and affects a wide range of research fields. However, traditional manufacturing methods are time-consuming, complex, and require expensive cleanroom facilities.A new method overcomes these limitations by utilizing aerosol jet printing to create customized equipment with various ...
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...
Makino Machine Tool Company, headquartered in Tokyo, Japan, and Fraunhofer Institute for Laser Technology (ILT), headquartered in Aachen, Germany, have collaborated to combine ultra-high speed laser material deposition (EHLA) and near net shape additive manufacturing (EHLA3D) with a five axis CNC platform. The new system developed can efficiently produce, coat, or repair complex geometric shapes o...
