Solar Insecticidal Lamps Internet of Things (SIL-IoTs), used for green agriculture, face theft and destruction due to high costs. To address this, we introduce SILC nodes by embedding cameras in SIL nodes, forming SIL-IoVTs for pest control and intruder monitoring. SIL-IoVTs involve omni-directional (SIL) and directional (camera) sensing models for area and target coverage. We formulate an optimal deployment model and develop a bi-level algorithm to solve it, iteratively deploying SIL nodes for pest control and cameras for monitoring. Simulation results show the method's effectiveness and progressiveness.

The rapid development of electric vehicles and the energy storage industry in recent decades produces a large number of spent lithium-ion batteries (LIBs). Traditional hydrometallurgical recycling of spent LIBs cathodes requires complex pretreatment processes to separate cathode active materials from the current collector, binder, and conductive agent to achieve faster leaching kinetics. However, unexpected enhanced leaching of spent LIBs is observed at the initial stage with the cathode sheet rather than the cathode powder. The self-driven enhanced leaching mechanism is proposed and verified with delicately designed electrochemical experiments. Based on the self-driven enhanced leaching mechanism, a galvanic cell system is built to leach valuable metals from spent LIBs cathodes and anodes efficiently. This research sheds light on the innovative recycling of spent LIBs without chemical reducing agents and enables the recycling of both spent LIBs cathodes and anodes simultaneously without complex pre-treatment processes. © 2023, The Authors.

Graphitic carbon nitride (g-C3N4) modified with N vacancies and Yb doping (YbCN) was synthesized by the thermal polymerization of ytterbium nitrate and melamine. The optimized sample showed a photocatalytic efficiency of 99.9% within 30 min for degrading tetracycline (TC) under visible light irradiation (λ > 420 nm), which was 24 times than pure g-C3N4. The experimental results and density functional theory (DFT) calculations support that the enhanced performance for photocatalytic decomposition of TC was attributed to the doped Yb3+ and the formation of N vacancies. The doped Yb3+ and induced polarization can expand the light responsive range and inhibit the recombination of photogenerated carriers. Moreover, the introduction of Yb3+ in g-C3N4 can accelerate the adsorption and activation of O2 to generate 1O2, •O2− and •OH. Furthermore, the catalytic photodegradation pathway of TC was revealed by HPLC-MS and DFT calculations. Finally, the optimized sample catalyst was also employed for photocatalytic decomposition of TC in practical conditions including tap, river, and lake water. It was found that inorganic ions in real water can influence the photocatalytic degradation of TC. This work disclosed a strategy for the rational design of efficient g-C3N4-based materials for practical environmental remediation. © 2023, The Authors. All rights reserved.

A long-standing challenge for natural enzyme based catalysis is low stability under harsh conditions. We herein demonstrated a de nova approach to synthesize an enzyme encapsulated in ZIF-8/GO (HRP@ZIF-8/GO). The hybrid coating of ZIF-8/GO could provide HRP with tolerance towards various harsh environments (*** the presence of proteolytic or chemical agents or at high temperature), as well as increased apparent substrate affinity. The feasibility of this biomimetic strategy for biostorage, enzyme cascades, and biosensing was also verified. Furthermore, owing to the introduction of functional graphene, the immobilized HRP displayed DNA-mediated controllable peroxidase (POD) activity, which was further employed to establish universal colorimetric aptasensor using antibiotic as model analyte. With this method, more analytical and biomedical applications of fragile enzymes can be exploited at extreme conditions, and it may also inspire other strategies to apply natural enzymes into industrial catalysis processes. © 2023, The Authors.

Image-based high-throughput plant phenotyping utilises various imaging techniques to automatically and non-invasively understand the growth of different plant species. These innovative imaging infrastructures are implemented to monitor plant development over time in indoor or outdoor environments. However, understanding the relationship between genotype and phenotype interactions under different environments remains challenging. This research study demonstrates superior extraction of leaf morphological features of different Arabidopsis thaliana ecotypes by analysing leaf geometry using a sequence of RGB images. Upon successful extraction of anatomical features, leaf length and area are converted into physical coordinates. Furthermore, considering these leaf features as 1D signals, the Fourier Spectrum is analysed, and most descriptive features are selected using PCA. Finally, leaf shape classification is established by training and testing five distinct ML models. A thorough evaluation of selected models demonstrates superiority in classifying two common leaf shapes of Arabidopsis plants. © 2024 IEEE.

Polyphenols with good reducibility have been widely used in water treatment. However, the effect of substituents on polyphenols on their reducibility and contaminant removal is unknown. In this study, the differences in the Cr(VI) removal rates by polyphenols with different electron-donating or -withdrawing groups (EDGs or EWGs) were systematically studied, and the correlation between the Cr(VI) removal and the electron-donating capacities of polyphenols was developed. 4-position substituted 1,2-dihydrobenzene derivatives (1,2-DHBs) with EDGs displayed a higher reaction rate than those with EWGs. There was little difference between 3-position and 4-position substitution for Cr(VI) removal by 1,2-DHBs. The presence of ortho-phenol groups was crucial to the Cr(VI) removal, while the effect of the number of ortho-phenol groups was not as great as expected. Robust correlations were established between the Hammett constant and the reaction rate between Cr(VI) and these 1,2-DHBs. Dispersion stability of polyphenols reflected by the absolute values of zeta potentials also affected Cr(VI) removal. Cyclic voltammetry and DFT analysis indicated that polyphenols with higher electron-donating ability had lower ionization energy and dissociation energy of O-H bond in phenol groups, which facilitated the electron transfer and deprotonation and promoted the conversion from Cr(VI) to Cr(III). The results of UV-vis, FTIR and XPS showed that quinones were produced as the intermediates of the reaction between Cr(VI) and 1,2-dihydrobenzene derivatives, which were eventually converted to carboxylic acids. This study provides a new idea for Cr(VI) removal from the aqueous solution and a reference for the potential wide application of polyphenols in water treatment. © 2024, The Authors.
