Image data acquired with fused multispectral information can be used for effective identification and navigation owing to additional beyond human vision, including thermal distribution, night molecular composition. However, the construction of photodetectors such capabilities is hindered by structural complexity arising from integration multiple semiconductor junctions distinct energy gaps lattice constants. In this work, we develop a colloidal quantum-dot dual-mode detector capable...

Due to their high sensitivity temperature and humidity, the applications of polylactic acid (PLA) products are limited. The stereo-complexation (SC) formed by poly(L-lactic acid) (PLLA) its enantiomer poly(D-lactic (PDLA) can effectively improve heat resistance hydrolysis PLA products. In this work, blended melt-spinning process PLLA/PDLA was carried out using a polyester fiber production line obtain with complete SC structure. effects high-temperature tension heat-setting on crystalline...
