The optical properties of photonic crystals are closely related to their lattice constants, which are usually required to be in the same order of magnitude as the operating wavelength. In a crystal material, the photonic crystal structure is formed by the periodic arrangement in space of units whose dielectric constant is different from that of the crystal itself, and whose lattice constant depend...
Recently, Professor Ni Zhenhua from the School of Electronic Science and Engineering at Southeast University, Professor Lv Junpeng from the School of Physics, Professor Liu Hongwei from the School of Physical Science and Technology at Nanjing Normal University, and Professor Zhou Peng from the School of Microelectronics at Fudan University collaborated to propose a van der Waals light-emitting dio...
Recently, exail (formerly iXblue) announced the acquisition of Leukos, an optical company specializing in providing advanced laser sources for metrology, spectroscopy, and imaging applications.Leukos was founded by the French XLIM Institute (a joint research department of the French National Academy of Sciences and the University of Limoges), with over 20 years of professional experience in the re...
In 2017, the detection of gravitational waves generated by the merger of binary neutron stars marked a significant breakthrough in physics. These waves reveal important information about the universe, from the origin of short gamma ray bursts to the formation of heavy elements.However, capturing gravitational waves from the merged residue remains a challenge as these waves avoid the detection rang...
Ensuring the integrity and quality of the welded hair clip is crucial in the assembly of electric motors. Usually, 160 to 220 hair clips are welded to each motor, and the accuracy of these welds directly affects the overall quality of the stator and motor. The traditional method of detecting these welds is difficult to balance the requirements of safety and accuracy, which often leads to damage to...
