Kagome structure originated as an old Asian Bamboo basket with both trigonal and hexagonal structures. Recently, the coexistence of charge density wave (CDW) state and superconductivity has been discovered in a new type of quasi-two-dimensional Kagome system AV3Sb5 with the kagome lattice of V atoms. Although the charge density wave and superconductivity have been investigated intensively, the non-trivial electronic band structure have been rarely studied.
The surface plasmon resonance effect caused by the interaction of free electrons on the surface of precious metals with light at specific wavelengths has been widely used. The ordered arrays of tightly expelled gold nanoparticles loaded on hydrogels has received much attention. However, the method of loading construction is to synthesize the noble metal nano-array on the solid substrate, and then transfer to the hydrogel to form the composite film structure, which not only makes the synthesis process complex, but also causes defects such as the introduction of dislocations in the transfer process, which greatly affects the quality of the composite array structure.
Atmospheric parameter sounding is a necessary input parameter and a reference for atmosphere and environmental protection departments to master the atmospheric conditions, conduct atmosphere and air quality forecasting and formulate corresponding emergency control strategies.
Nitrous oxide (N2O) and carbon monoxide (CO) play important roles in global warming. However, there are many difficulties in reliable long-time monitoring, especially for N2O, as the concentration of N2O in atmospheric is only a few hundred part per billion, while the compatibility precision is 0.1 part per billion recommended by World Meteorological Organization (WMO).
Organic-inorganic halide perovskite materials have excellent optical capture capacity and carrier conductivity. Perovskite solar cells, with amazing power conversion efficiency, show great application prospects.
