Fast on-site detection of potentially toxic metals in soils is crucial for soil remediation and contamination monitoring. Laser-induced breakdown spectroscopy (LIBS) technology has been used widely in soil remediation, food safety, biomedical analysis, and potentially toxic metal detection in crops. However, the detection of potentially toxic metals in soil by LIBS technology is currently performed in laboratory after drying
The thermal simulation analysis results are used to predict the temperature distribution of the spacecraft in orbit and guide the thermal design layout. Due to the complexity of aerospace instruments，too many thermal design parameters make it impossible to automatically modify the thermal models.
Radiative cooling is a ubiquitous passive cooling process that radiates heat out to the universe through the atmospheric transparency window. Recent advances in nanophotonics have enabled latest breakthroughs in daytime radiative cooling and have inspired intense research efforts in this field.
The Texas horned lizard (Iguanidae: Phrynosoma cornutum) inhabiting arid regions utilizes its dorsal integument to access water sources. Thanks to its highly-evolved integument consisting of microsized overlapping scales showing water repellency and nanosized capillary channels showing water affinity, water can be directed preferentially towards the lizard’s snout, achieving the power-free transportation.
With the rapid development of numerical control technology in the industrial field, the accuracy of angular displacement measurement technology has become more demanding.
Metamaterial absorbers (MA) based on subwavelength periodic patterns can achieve perfect absorption at any target wavelength by rationally designing their geometric parameters. Due to their ultra-thin thickness and near-field enhancement, MAs are widely used in infrared imaging, thermal emitters, photodetection, solar energy harvesting, gas detection, etc. However, since the resonant nature of plasmon excitation, general MAs can only achieve perfect absorption in a narrow wavelength range.
