Improving the efficiency of photogenerated carrier separation by designing heterojunction photocatalysts remains an important challenge. In this study, TiO2 nanofibers were prepared by electrospinning, Bi/Bi2WO6/TiO2 heterojunctions were constructed by hydrothermal method, and verified by characterization techniques. The heterojunction had good photodegradation activity to sulfamethoxazole (SMX) under ultraviolet and visible light irradiation (96.4% within 60 min). The enhanced photodegradation activity of Bi/Bi2WO6/TiO2 nanocomposites can be attributed to the synergistic effect of S-cheme mechanism and Bi metal plasma action. In addition, Bi metals can generate a large number of electron-hole pairs under the action of surface plasmon resonance (SPR). In addition, the influence factors such as pH, SMX concentration and catalyst loading were studied. According to the detected intermediates, the photocatalytic degradation pathway of SMX was studied. The results of free radical capture experiment and ESR show that ·O2- and h+ free radicals play an important role in the decomposition of SMX. The cyclic experiments show that Bi/Bi2WO6/TiO2 nanocomposites have excellent stability and reuse characteristics. Finally, the mechanism of photocatalytic degradation of SMX was described. This study provides a promising perspective for the preparation and development of S-Scheme heterojunction photocatalysts based on Bi2WO6. © 2024, The Authors. All rights reserved.

Aqueous zinc-ion batteries (AZIBs) have garnered attention due to their low cost, abundant resources, and safety features. However, finding high-performance cathode materials for AZIBs remains a key challenge. Herein, we report the synthesis of a small molecular organic compound with hydrogen bonds and multiple active groups, hexaazatriphenylenehexacarboxy triimide (HHT). As a cathode material for AZIBs, the electrochemical performance of HHT was evaluated, demonstrating an outstanding discharge capacity of 574 mAh g-1 at 0.05 A g-1 with approximately capacity retention of 70% after 1000 cycles at 2 A g-1, and high-rate capability. The study on the electrode reaction mechanism shows that both Zn+2 and H+ ions interact with HHT. The flexible Zn//HHT aqueous battery also has superior discharge specific capacity, high cycle stability and excellent mechanical flexibility, and its maximum volume energy density can achieve 4.32 mW cm-3, showing the future application prospect in wearable electronics. © 2025, The Authors.

This work solves the angle-of-arrival (AOA) source tracking problem in 3-dimensional (3D) space utilizing a position-unknown unmanned aerial vehicle (UAV). An AOA sensor is carried by a mobile UAV, and the conventional self-positioning module, such as the global positioning system (GPS), is not allowed due to environmental limitations. Thus, to guarantee the feasibility of this source tracking problem, at least two position-known landmarks are required. Firstly, the detailed problem formulation is provided with the consideration of measurement drift caused by sensor-vehicle installation errors. Secondly, all the unknown states are estimated using a proposed extended Kalman filter (EKF). Thirdly, a UAV moving direction optimization algorithm is developed to promote the estimation accuracies of the source, UAV and measurement drift. Finally, simulation examples demonstrate the characteristics of the proposed method.

Graphdiyne (GDY), a new carbon allotrope, is composed of two types of hybridized (sp and sp2) carbon atoms to form a 2D planar network structure. After being synthesized in 2010, pristine GDY has attracted the attention of researchers, because of its large π-conjugated structure and excellent electronic properties. In recent years, there have been many reviews on GDY, but most reviews only briefly describe its synthesis and applications. Due to experimental limitations, it is difficult to gain insight into the electronic structure of GDY concerning its properties and applications. At the same time, there is also a lack of a thorough understanding of the application mechanism of GDY and GDY-based materials. By utilizing theoretical computation, not only the above problems can be solved but also experimental results can be predicted. Thus, in this paper, we review some of the physical properties of GDY-based materials from the perspective of theoretical calculations. Then, their theoretical prediction in the fields of energy storage and conversion is introduced, which points out the research direction and provides a theoretical basis for the experiments. It is hoped that this Review will play a positive part in developing GDY and its related calculations.

Investigating the Potential of the Limestone Calcined Clay Cement with Cement Content Below 50 Wt.%: Hydration Properties and Environmental Impact Analysis

Limestone calcined clay cement (LC3) is a promising strategy and technology to mitigate the climate change in the field of cement-based materials. The purpose of this work was to systematically investigate the properties of LC3 system with cement content below 50 wt.%, in which two calcined clays with metakaolin content of 33.2% (MK30) and 50% (MK50) were used for comparison. Cement pastes and mortars were prepared with four coupled replacement levels of 50 wt.%, 65 wt.%, 75 wt.% and 85 wt.% by calcined clay and limestone. Compressive strength of mortars was tested up to 90 days. The hydration process was monitored in detail by isothermal calorimetry, phase assemblages calculated by quantitative XRD-Rietveld refinement and the reaction of metakaolin in calcined clay calculated by mass balance approach. Finally, an environmental performance indicator with consideration of CO2 emissions and compressive strength was also introduced to evaluate the application feasibility of these different low-cement LC3 systems. From the observation of the experiment, cement hydration dominated the compressive strength of LC3 system before 3 days, while the pozzolanic reaction between metakaolin and CH as well as the synergistic reaction between metakaolin and limestone support the late-strength development regardless of the calcined clay types. Compared to MK30, MK50 was more helpful for the precipitation of hydrates and densification of microstructure, resulting in a higher compressive strength. Environmental performance indicator showed that LC3-50 and LC3-35 prepared by MK30, and LC3-50, LC3-35 and LC3-25 prepared by MK50 can be treated as ideal systems, as they presented much lower environmental impact and maintain desired compressive strength as well. The findings of this work present a promising contribution to realizing the environmental sustainability of cement production. © 2023, The Authors. All rights reserved.

This paper presents a hybrid energy harvester based on tapered rollers with an electromagnetic generator (EMG) component and a triboelectric nanogenerator (TENG) component for ultra-low frequency wave energy harvesting. The chaotic pendulum is adjusted to adapt the wave excitation under different sea conditions, ensuring that the device achieves optimal output performance. At excitation frequency of 1Hz and the tilt angle of 60°, the open-circuit voltage peaks of 8.4 and 132 V can be achieved by the EMG and TENG, respectively, corresponding to the power outputs of 4.38 and 0.078 mW, respectively. It was demonstrated that the device can easily light up over 360 red light-emitting diodes.
