Preparation and Degradation of Waste Polycarbonate-Derived Epoxy Thermosets and Composites
waste polycarbonate diphenyl carbonate one-hundred percent atom efficiency epoxy recycling of CFRP aminolysis
2023/12/5
We report a robust, 100% atom-efficiency strategy for preparing waste polycarbonate (WPC)-derived epoxy resin. To demonstrate the preparation process, we perform a pyridine-catalyzed model reaction be...
Epoxy vitrimer based on borate ester bond for green degradation, closed-loop recycling, and ready reprocessing
Green degradation Thermoset Dynamic covalent bond Recyclable
2023/12/1
The three-dimensional network of traditional epoxy resin endows it with suitable properties, but it also presents challenges in reprocessing and recycling. Recent years have witnessed the development ...
Thermal Degradation Behavior of Epoxy Resin Containing Modified Carbon Nanotubes
epoxy resin carbon nanotubes silicone thermal degradation flame retardancy activation energy
2023/12/1
Via the surface-grafting of carbon nanotubes (CNTs) with a silicon-containing flame retardant (PMDA), a novel flame retardant CNTs-PMDA was synthesized. The flame retardancy was tested by cone calorim...
Network Degradation Assessed by Evolved Gas Analysis-Mass Spectrometry Combined with Principal Component Analysis (EGA-MS-PCA): A Case of Thermo-Oxidized Epoxy/Amine Network

2023/11/16
To study the degradation of thermosetting polymers, we apply a novel method to simultaneously study the chemical structural changes and network topology: evolved gas analysis-mass spectrometry combine...
Analysis of atmospheric visibility degradation in early haze based on the nucleation clustering model
Early haze Initial nucleation process Heterogeneous cluster Visible-light absorption
2023/3/1
The initial nucleation of ultrafine particle recently attracts more attention as a key factor in visibility degradation during early haze. In this study, we have performed Density Functional Theory (D...
ESTIMATE OF DTM DEGRADATION DUE TO IMAGE COMPRESSION FOR THE STEREO CAMERA OF THE BEPICOLOMBO MISSION
Space Photogrammetry DTM Reconstruction Accuracy Area-based Image Matching Compression
2016/11/8
The great amount of data that will be produced during the imaging of Mercury by the stereo camera (STC) of the BepiColombo mission needs a compromise with the restrictions imposed by the band downlink...
