Thermoplastic polyurethane (TPU) elastomers based on polyoxytetramethylene glycol (PTMG) with 2000 g·mol–1 as soft segments (SSs) and isocyanates well their reaction butanediol hard (HSs) were synthesized. The three-dimensional supramolecular networks constructed in TPU by the formation of physical HSs-rich domains via microphase separation, hydrogen bonding, microcrystallization, which are dominated chemical structure HSs. robust stretchable an excellent tensile strength 32 MPa elongation...
The glycolysis of PET catalyzed by hollow micro-sized nanoaggregates is a highly effective and sustainable way to tackle the escalating plastic waste problem create circular economy.
Employing polyethylene terephthalate (PET) wastes as a linker source is cost-effective, renewable, and sustainable approach to attain high-performance nano-MOFs for water adsorption photocatalysis.
2D MOF nanosheets prepared using a high-gravity reactive precipitation method exhibit high catalytic activities toward Knoevenagel condensation and the glycolysis of poly(ethylene terephthalate).
The wear condition of steel rails directly affects the safety railway operations. Line-structured-light visual measurement technology is used for online rail due to its ability achieve high-precision dynamic measurements. However, in measurements, random deviation plane caused by vibration railcar results changes actual measured profile relative cross-sectional profile, ultimately leading deviations. To address these issues, this paper proposes a method three-dimensional profiles based on...
The amphiphilic acylated chitosan-g-polyisobutylene copolymers (ACS-g-PIB) could be achieved via highly effective nucleophilic substitution of living PIB chains carrying the oxonium ion (PIB-THFn+) with −NH2 side groups along ACS backbone, in which grafting number (GN) was mediated by changing [PIB-THFn+]/[−NH2]. obvious microphase separation micromorphology formed due to incompatibility between hydrophilic backbone and hydrophobic branches. Crystallization from became weaker while roughness...

In the pursuit of circular economies aimed at achieving sustainable development, chemical recycling emerges as a promising method for transforming polycarbonate (PC) plastic into value-added monomer. Herein, methanol dispersions ultrasmall ZnO nanoparticles (∼4 nm) are firstly utilized catalytic methanolysis PC. Under mild reaction conditions (120 °C, 1 h) with low catalyst amount (0.8 wt %), complete conversion PC and 97.8% yield BPA could be achieved. The above also capable depolymerizing...
Abstract LIO-SAM is an extensively utilized SLAM (Simultaneous Localization and Mapping) algorithm, featuring integrated lidar-inertial odometry framework for high-precision, real-time trajectory estimation mapping in mobile robots. In this paper, we integrate the lidar Iris loop detection algorithm into to solve poor of itself effect Scan Context resulting from varying directions passing through same location. Additionally, enhanced dynamic point filtering relying on ERASOR developed...
