A spiro diacetal structure based on renewable resources was utilized to synthesize thermosets combining ready recyclability and high performance.
Vitrimers undergoing dynamic bond exchange enable reprocessing and recycle of thermosets. However, vitrimers are susceptible to creep, leading their poor dimensional stability, which limits applications. Here, a facile method via integration metal complexes was utilized address this issue, cross-linked polyimine selected as an example vitrimer. Three different were introduced into vitrimer one-pot preparation involving the formation cross-linking polyimine. The addition 0.5 mol % Cu2+...
We report a ratiometric fluorescent sensor based on semiconducting polymer dots chelated with terbium ions to detect bacterial spores in aqueous solution. Fluorescent polyfluorene (PFO) serve as scaffold coordinate lanthanide that can be sensitized by calcium dipicolinate (CaDPA), an important biomarker of spores. The absorption band PFO extends deep UV region, allowing both the reference and sensitizer excited single wavelength (∼275 nm). fluorescence remains constant reference, while Tb3+...
Recycling thermosets have become extremely important due to their ecological and economic benefits. The development of that undergo reversible polymerization provides a solution the end-life disposal issue thermosetting materials. However, synthesis recycling current chemically recyclable are harsh, complex, energy-intensive, stability is often low. Here, we designed asymmetric acetal-containing (PRCs) from general phenolic resin 1,4-cyclohexanedimethanol divinyl ether through one-step...
A bio-sourced, low-toxic monomer was facilely synthesized and used to build controlled degradable, strong tough thermosetting plastics.
A green approach in the gas-exfoliation and <italic>in situ</italic> templating-assistant synthesis route was developed to prepare hierarchical lignin-derived porous carbon (HLPC) using non-corrosive, recyclable ZnCO<sub>3</sub> as an activator.
Post-consumer plastic bags were upcycled to covalent adaptable networks (CANs) based on internally catalyzed anhydride monoester transesterification.
This communication reports an efficient visual detection method of Cu2+ by L-cysteine functionalized gold nanoparticles in aqueous solution. Upon exposure to Cu2+, the nanoparticle solution changed from red blue, response surface plasmon absorption dispersed and aggregated nanoparticles. colorimetric sensor allows a rapid quantitative assay down concentration range 10(-5) M. Recognition formation aggregates are proposed occur via 2 : 1 sandwich complex between Cu2+.
Student-centeredness is a teaching theory proposed by British and American scholars in linguistics, psycholinguistics, applied second language acquisition theory. “The student-centered approach different from the traditional teacher-centered approach, but it implemented teacher-led environment. In this study, word2vec, paragraph2vec, pos2vec LDA (latent dirichlet allocation) are combined to form semantic representation vector for college business English translation. The key point of...
In this paper, we present a novel blockchain-enabled approach to opportunistic federated learning (OppCL) for intelligent transportation systems (ITS). Our integrates blockchain with OppCL streamline the of autonomous vehicle models while addressing data privacy and trust challenges. We deploy resilient countermeasures, incentivized mechanisms, secure gradient distribution combat single-point failure verification attacks. Additionally, integrate Byzantine fault-tolerant algorithm (BFT) into...
Opportunistic Federated Learning (OppCL) is a widely adopted distributed learning approach for Intelligent Transportation Systems (ITS). However, the exchange of information among parties raises privacy concerns, and OppCL training faces drawbacks such as high number iterations, long time, low efficiency. This paper proposes an innovative framework privacy-preserving reputation-based (PR-OppCL) to address these challenges. Firstly, we introduce reputation value considering factors like time...
Gaseous combustion product, a mixture of radiating gas CO2, H2O and nonradiating N2, O2, absorbs emits radiation spectrally selectively. Accurate simulation heat transfer inside chamber requires the line-by-line model which is impossible for engineering practice because prohibitive computation time cost. The simplified gray most popular used in CFD simulation. However, accuracy this has not been systematically evaluated. Several cases have simulated with evaluated by result more accurate...
Hollow polyphosphazene microspheres with highly cross-linked chemical structures were prepared by a template-induced assembly mechanism. The hollow display good stability towards Au nanoparticles.
Epilepsy is one of the most common disorders brain. Clinically, to corroborate an epileptic seizure-like symptom and find seizure localization, electroencephalogram (EEG) data are often visually examined by a clinical doctor detect presence epileptiform discharges. Epileptiform discharges transient waveforms lasting for several tens hundreds milliseconds mainly divided into 7 types. It important develop systematic approaches accurately distinguish these from normal control ones. This...
