Summary: In order to enhance the flame retardancy and smoke suppression of epoxy resin (EP), a novel inorganic-organic nanocomposite flame retardant, zinc ferrite@polyphosphazene (ZF@PZS) was developed. The combination of inorganic zinc ferrite and organic polyphosphazene improved the compatibility and flame retardant performance. The synergistic effects of ZF@PZS showed excellent flame retardant and smoke suppression properties in the EP matrix. Compared to neat EP, the EP with 5 phr ZF@PZS exhibited higher limiting oxygen index, lower heat release rate, smoke production rate, and carbon monoxide production. Furthermore, the addition of ZF@PZS resulted in the generation of denser, more stable, and rigid residues, leading to improved flame retardancy.

Summary: Cellulose nanocrystals (CNCs) are used as a bio-based carbon source in an intumescent system. However, CNCs have low thermal stability and adverse impact on performance. By designing phosphazene-containing CNCs (PIN-CNCs), thermal stability and charring ability are improved. PLA composites with PIN-CNCs and flame retardants show enhanced flame retardancy and mechanical properties.

Summary: Multifunctional composites containing multi-walled carbon nanotubes (CNTs), ammonium polyphosphate (APP), and a commercial multifunctional epoxy oligomer (MEO) as chain extender were prepared via melt blending to improve both the mechanical and flame retardant properties of polylactide/poly(butylene adipate-co-terephthalate) (PLA/PBAT) composites. The addition of 6% CNTs and 10% APP in the PLA5-PBAT5/10A/6C composite resulted in optimal flame retardant properties, with a limited oxygen index of 28.3%, decreased peak heat release rate (pHRR) of 368 kJ/m(2), and total heat release (THR) of 72 MJ/m(2). The co-continuous phases in the composite also improved its mechanical properties compared to PLA8-PBAT2 composites.

Summary: With the development of plant phenomics, plant disease identification through leaf images using convolutional neural networks (CNN) has become an effective and economic approach. However, CNN's representation power remains a challenge in handling small datasets. In this study, a new method called PiTLiD is proposed, which utilizes pretrained Inception-V3 CNN and transfer learning to identify plant leaf diseases with small sample sizes. Experimental results show that PiTLiD outperforms other methods. This research provides a plant disease identification tool based on deep learning algorithm for plant phenomics.
