Laser gas analysis can achieve high sensitivity and selectivity in gas detection. The multi-component capability and wide dynamic range of this detection method help analyze gas mixtures with a wide concentration range. Due to the fact that this method does not require sample preparation or pre concentration, it is easy to adopt in the laboratory or industry.Gas analysis is crucial for determining...
In 2024, the laser industry will still reach new heights, although some predicted concerns have been fulfilled! From beginning to end, the development path of the manufacturing industry has been full of uncertainty, but as time passes and we enter a new year, new technologies continue to emerge like mushrooms after rain.In 2025, practitioners in the laser and manufacturing industries still face ma...
Recently, Qing Guangyan, a researcher team from the Research Group on Bioseparation and Interface Molecular Mechanism (1824 Group) of Biotechnology Research Department of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, designed and prepared a highly solid cellulose photonic hydrogel with reconfigurability and mechanical discoloration. This preparation method opens up a new way t...
Researchers have made significant breakthroughs in controlling optical polarization, which is a key characteristic of various applications such as augmented reality, data storage, and encryption.This new method was developed by a group of scientists using liquid crystals to create holograms, which can manipulate the polarization of light at different points. This represents a significant advanceme...
Quantum photonics is one of the important research directions in the quantum field, which utilizes the unique properties of light at the quantum level. The core of this field is the deterministic single photon source, which sequentially emits individual photons through spontaneous emission and is the cornerstone of quantum communication, computing, and secure encryption. However, under environment...
