State-of-health (SOH) is an important indicator for the maintenance and safe operation of batteries, and it is crucial for accurately predicting SOH. To address problems that the noise present in the original data lead to inaccurate prediction results. An Long-Short-Term-Memory (LSTM) method for SOH prediction is proposed based on the joint noise reduction model of complete ensemble empirical mode decomposition adaptive noise (CEEDMAN) and Savitzky-Golay (SG) filtering. Firstly, seven health indicators (HIs) were extracted by analyzing the voltage and current curves, and HIs with higher correlation with SOH were selected using Pearson correlation coefficient. Then, Intrinsic Mode Functions (IMF) components generated from SOH by CEEMDAN are divided into noise-component, noise-dominant-component, useful-signal-dominant-component, filtered noise-dominant-component and useful-signal-dominant-component are reconstructed into filtered SOH. Finally, the LSTM model is used for SOH prediction. Experiments show that proposed model captures the capacity regeneration phenomenon well with high prediction accuracy, and errors are all below 1.9%.

Plastic pollution and the associated adversities have been intensively researched recently, providing ample solutions with diverse possibilities and yielding a considerable corpus of literature in plastic waste management (PWM). Regardless of the vast range of techniques formulated, such as mechanical recycling and chemical depolymerization, many of these approaches have limitations including significant costs, ecological threats, and inefficiencies in handling diverse plastic types. Manual analysis of these challenges and the reported solutions from the vast collection of interdisciplinary research papers is extremely laborious. Herein, using tools of data science to create a network of ∼350,000 papers and subsequent clustering to identify various protocols for PWM and determining the main paths of their knowledge evolution, we review their progress. The broad objective of this analysis is to provide a comprehensive understanding of different PWM techniques, with a focus on the importance of integrated, technologically advanced, and environmentally conscious approaches to solve plastic pollution. We identify four major categories of PWM (physical, chemical, physio-chemical, and biological) and analyze their mechanistic details. Our study highlights the critical need for the establishment of more sustainable PWM methodologies, supporting the integration of artificial intelligence to refine process optimization and cultivate interdisciplinary collaboration focused on advancing a circular economy and reducing plastic waste. Together with a deep discussion on the gaps between the set goals and the current achievements identified, these analyses could be a useful tool to confront the PW crisis.

A novel electrochemical sensing platform for dopamine (DA) detection was developed by fabricating the ternary composite of Ti3C2Tx MXene (M) and reduced graphene oxide (rGO) with platinum nanoparticles (Pt NPs) through microwave-assisted hydrothermal heating. The exceptional electrical conductivity and rich surface chemistry of MXene provide abundant active catalytic sites for electrochemical reactions, while the large surface area of rGO facilitates ion and electron pathways. The integration of rGO in the MXene sheet, forming MXene-rGO (M_rGO) heterostructure composite, imparts long-term stability to the 2D heterostructure while providing additional electron pathways and significantly enhancing conductivity. Pt NPs synergistically increased the electrocatalytic activity of the electrochemical sensor's performance. Ternary nanocomposites were fabricated with different weight percentages (wt.%) of Pt NPs, ranging from 5 to 20. Characterizations of the samples (rGO, M, M_rGO, and 5–20 wt% Pt@M_rGO) were conducted through X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), Raman spectroscopy (RAMAN), and X-ray spectroscopy (XPS). Electrochemical evaluations of the samples were investigated in 0.1 M phosphate buffer solution (PBS) using cyclic voltammetry (CV) and differential pulse voltammetry (DPV) analyses. The analysis revealed that the ternary composite with 5 wt% of Pt NPs (5% Pt@M_rGO) exhibited a uniform well-distribution of Pt NPs and the highest oxidation peak for DA oxidation in CV studies. The presence of metal nanoparticles, aided by the synergistic effects between the MXene and rGO, resulted in an excellent DA sensor with a 0.147 μM detection limit from 1 to 14 μM linearity range. The sensor demonstrated outstanding selectivity, reproducibility (RSD values of 8.10%), repeatability (RSD value of 2.46%) and, excellent stability over 14 days. In human urine samples, the sensor exhibited excellent DA recovery (88.62–110.65%). This study significantly advances the development of electrochemical sensors for DA detection by introducing a rapid, facile and, efficient method for fabricating ternary composites. The fabricated sensor exhibited high sensitivity, excellent selectivity, and robust electrochemical performance, offering valuable insights into human and behavioral health advancements.

HKUST-1 MOF was crystallized within chitosan matrix to form xerogel beads using an in-situ growth approach. Under mild conditions, CS@HKUST-1 xerogel beads exhibit high specific surface areas (SBET) up to 923 m2 g−1. By further incorporating graphene oxide (GO) to form ternary CS-GO@HKUST-1 xerogel beads, the HKUST-1 MOF structure remained stable for up to two days in a water solution at room temperature, whereas the MOF powder and CS@HKUST-1 xerogel beads underwent significant framework collapse within a day. CO2 adsorption measurements on these xerogel beads also show promising CO2 uptakes, surpassing 2.5 mmol g−1 at 298 K and 1 bar. Moreover, these composites could be regenerated for more than 10 cycles without any loss of quantity adsorbed.

It is a challenging and meaningful task to design a piezo-photocatalyst with excellent performance under mild mechanical stirring conditions rather than ultrasonic irradiation. Herein, a hydraulic-driven piezo-photocatalytic process was proposed, using MoS2-based heterojunction as catalysts for diclofenac sodium (DCF) degradation. A magnetically retrievable MoS2/TiO2/Fe3O4 composite was designed and successfully prepared by a facile one-step solvothermal process. Among various heterojunction composites and pure MoS2, the ternary composite MoS2/TiO2/Fe3O4 exhibited the strongest piezo-photocatalysis capability, with a DCF degradation efficiency of 99.6% and a pseudo-first-order rate constant of 0.733 min−1. Additionally, the degradation efficiency of DCF was still up to 85.2% in 6 min after 5 cycles by MoS2/TiO2/Fe3O4. The ternary composite can be easily collected and separated using a magnet. There was an optimum hydraulic gradient value (0.45 s−1) for DCF degradation. •OH played a major role in DCF degradation during the hydraulic-driven piezo-photocatalytic process. A satisfactory DCF degradation was found in the actual water media. The results verify the existence of a synergetic effect between piezo and photocatalytic processes. Thereupon, the hydraulic-driven piezo-photocatalysis can be an efficient, sustainable, and energy-saving process for water treatment.

Intermetallic compounds typically exhibit limited plastic deformation capacity due to challenges in activating dislocation slip and deformation twinning, coupled with a lack of alternative deformation mechanisms. Ti–Pt alloys are a prevalent type of intermetallic compound utilized in high-temperature shape memory alloys and as materials for energy applications in electric fields. However, they often exhibit poor deformation capability. Here, we prepared a low-symmetry intermetallic phase, Ti4Pt3, which demonstrates significant plastic deformation capability. This phase features a high density of parallel planar defects, resulting in an exceptionally large lattice periodicity perpendicular to these defects. Through in-situ scanning electron microscope compression tests, we observed substantial plastic deformation in this new phase. Analysis of the deformed Ti4Pt3 phase revealed that the dense planar defects create uniformly distributed sites of internal stress concentration, enabling a rapid increase in back stress within crystals. This phenomenon leads to notable lattice rotation and localized order-disorder transitions, both crucial mechanisms facilitating plastic deformation and enhancing deformation capacity. Our research underscores the potential of leveraging structural asymmetry to enable unconventional deformation mechanisms, thereby enhancing the plasticity of intermetallic materials.

Supported Pd catalysts has found wide applications in reductive etherification of aldehydes. However, the synthesis of furfural-derived ethers on Pd catalysts has encountered great challenges because several side reactions such as over-hydrogenation of furan ring and decarbonylation always occur simultaneously under the reaction conditions. We herein reported the catalytic performance of Pd nanoparticles (∼4 nm) supported on the external surface of layered structured PLS-3 zeolite with narrow pore size (<0.4 nm) and large external surface area (80–100 m2/g). The PLS-3 with Si/Al of 92 having total acid sites of 93 μmol/g showed satisfied ether selectivity. Pd nanoparticles located on the external surface showed better etherification selectivity than those confined in the framework, due to the less diffusion limitation of furfural acetal as an intermediate.

Inspired by the capillary effect in nature (such as water transport in soils) and droplet-drive performance of Nepenthes, a new driving strategy for emulsion separation membrane based on the synergistic effect of capillary force and progressive wettability-induction force was proposed. It is prepared by a one-step, simple continuous, electrospinning process. By adjusting solutions and spinning parameters, the membrane obtains its capillary structure and progressive oleophilicity in one-step preparation. Attractively, the membrane shows separation efficiency and excellent permeability, with a flux of 384801 L m−2 h−1 bar−1 for the oil-water mixture, and the little water content of less than 18 ppm. And for emulsions, the flux even reaches 50000 L m−2 h−1 bar−1 and the separation efficiency reaches 99.95%. Furthermore, the membrane has excellent mechanical-stability: at 80 kPa transmembrane pressure, it can still effectively prevent water's penetration. Drawing inspiration from nature, the incorporation of capillary force and progressive wettability-induction force into the separation membrane as an additional dual emulsion separation driving force proves to be a highly effective and versatile approach. This method provides a way to solve the general flux-efficiency balance problem of oil-water separation and also provides a new strategy for the preparation of separation membranes for various purposes.

In recent years, there has been significant interest in utilizing this green biopolymer for energy storage devices. This review thoroughly examines lignin structure, chemistry, and classification based on separation techniques. It then explores the most recent breakthroughs in creating carbon materials (nanosheets, nanofibers, spheres, composites, and 3D hierarchical porous carbon) from lignin, discussing its versatility in supercapacitors and batteries. Finally, this study highlights future materials and their prospects, the critical challenges which must be addressed while suggesting future research avenues for lignin-derived carbon materials in energy storage. By combining insights from different studies, this review aims to offer readers a thorough understanding of how lignin-derived carbon materials could play a crucial role in promoting sustainable energy solutions.

The rational design of van der Waals heterostructure offers an effective avenue for improving the photocatalytic efficiency of individual two-dimensional materials, garnering extensive interest in recent years. Herein, the feasibility of GeC/Ga2SO heterostructure as a photocatalyst for overall water splitting has been explored based on the first-principles calculations. Our findings reveal that the electronic bandstructure of GeC/Ga2SO heterostructure can be engineered in staggered or straddling band alignment depending on stacking patterns. Particularly, in the GeC/Ga2SO heterostructure with staggered band alignment, an intrinsic built-in electric field is established at the interface with the direction from GeC to Ga2SO, facilitating the formation of a direct Z-scheme heterostructure. Also importantly, the band-edge positions of Z-scheme GeC/Ga2SO heterostructure cross the water redox potentials, providing adequate driving force for both the reduction and oxidation reactions of water. Gibbs free energy calculations demonstrated that the photocatalytic overall water splitting can proceed spontaneously in the neutral environment (pH = 7) under light irradiation. Moreover, GeC/Ga2SO heterostructure exhibits good thermal stability and a strong (magnitude in 105 cm−1) and broad (from visible to ultraviolet light) optical absorption. Finally, through applying the tensile strain, further enhancements in the optical absorption and carrier redox ability are achieved due to the favorable modulation in the bandgap. Therefore, all these features make GeC/Ga2SO heterostructure show great potential in the application of photocatalytic water splitting.
