As a focal point in contemporary land system science research, land use transitions significantly impact the ecological environment. Zhaosu County, a typical ecological county in the arid region of Northwest China, offers significant insights into the processes of land use transition and their effects on the ecological environment. Studying these dynamics is crucial for the county's rational spatial allocation and sustainable development. Based on the remote sensing monitoring data of land use in Zhaosu County in 2000, 2010, and 2018, this article classified land use according to three primary functions: "production, living, and ecological". By comprehensively applying the research methods of land use transfer matrix model, land use center of gravity shift model, eco-environmental quality index, and regional ecosystem contributions, this paper quantitatively analyzed the process of land use functional transition and spatial transition in Zhaosu County from 2000 to 2018 and scientifically investigated the spatiotemporal distribution characteristics of land use transitions as well as their varying impacts on the ecological environment. This research indicates that: (1) From 2000 to 2018, the ecological land in Zhaosu County initially experienced an increase followed by a decrease; in contrast, production land underwent a decline before rebounding, while living land has shown a continuous upward trajectory. (2) The spatial distribution of the three primary functional land uses in Zhaosu is unbalanced, and the center of gravity of all land uses has shifted during the study period. Among them, the center of gravity of water area and other ecological land underwent the most pronounced displacements, and the spatial migration intensified initially before gradually diminishing, while the degree of deviation of urban living land was the least pronounced. (3) The comprehensive eco-environmental quality index of Zhaosu County continued to decline from 0.584 in 2000 to 0.549 in 2018, indicating a persistent degradation trend of the ecological environment quality. (4) The negative effects of the ecological environment in Zhaosu County outweighed the positive effects, and the main factors contributing to the decline in ecological environment quality were grassland degradation and the decline of the snowline.

It is a great desire of advanced designed materials for electricity generation, storage, and utilization with boosted activity, multifunctionality, compatibility, stability, and durability. Organic ionic materials (OIMs) with superior conductivity, modifiability, and thermal/cold tolerance have great potential in meeting the demand. Ionic liquids, ionic polymers, polyelectrolytes, and new‐emerging composite materials like ionic gels, ionic woods, and metallated covalent organic frameworks have been boomingly developed in recent years, with elaborated design of which, enhanced performance of burgeoning energy materials such as higher electrical output, larger energy capacity, wider tolerance of temperature and/or humidity, and longer durability have been promoted. Despite a few reviews that have generalized the applications of single‐type OIMs in a certain field, there is a lack of comprehensive reviews focusing on advanced design of OIMs for boosting electricity generation, storage, and utilization. Herein, the new development of OIMs is timely and systematically reviewed focusing on electricity generation (generators), storage (batteries and supercapacitors), and utilization (sensors and actuators). Synthesis and modification strategies are summarized for material design, after which, fundamentals and mechanisms are illustrated as theoretical support. Then, advanced designs of OIMs are elaborated by taking electricity generation, storage, and utilization processes into consideration, followed by putting forward perspectives.

Zinc metal stands out as a promising anode material due to its exceptional theoretical capacity, impressive energy density, and low redox potential. However, challenges such as zinc dendrite growth, anode corrosion, and side reactions in aqueous electrolytes significantly impede the practical application of zinc metal anodes. Herein, 3‐(1‐pyridinio)‐1‐propanesulfonate (PPS) is introduced as a zwitterionic additive to achieve long‐term and highly reversible Zn plating/stripping. Due to the orientation polarization with the force of electric field, PPS additive with π–π conjugated pyridinio cations and strong coordination ability of sulfonate anion tends to generate a dynamic adsorption layer and build a unique water–poor interface. PPS with steric hindrance effect and strong coordination ability can attract solvated Zn2+, thereby promoting the desolvation process. Moreover, by providing a large number of nucleation sites and inducing zinc ion flow, the preferred orientation of the (002) crystal plane can be achieved. Therefore, the interfacial electrochemical reduction kinetics is regulated and uniform zinc deposition is ensured. Owing to these advantages, the Zn//Zn symmetrical cell with PPS additive exhibits remarkable cycling stability exceeding 2340 h (1 mA cm−2 and 1 mA h cm−2). The Zn//V2O5 full cell also delivers stable cycling for up to 6000 cycles. [ABSTRACT FROM AUTHOR]

Emerging tribovoltaic nanogenerator (TVNG) technology, which can capture mechanical energy at dynamic semiconductor interfaces and generate instant direct current (DC) outputs, is considered promising to mitigate growing energy demand. However, the unsatisfactory charge excitation and extraction efficiency limit its electrical output stability and even practicability. Here, a novel strategy is proposed to synergistically modulate charge generation and transfer dynamics by integrating ferroelectric and photovoltaic effect with tribovoltaic effect, and thus a multi‐effect coupled Schottky TVNGs is, for the first time, developed. Research indicates that such coupling mechanism involving ferroelectric polarization, photoexcitation, and triboelectricity can allow TVNGs to jointly collect light and mechanical energy to excite more charges, and meanwhile, incorporation of strong electric fields can also be induced by controlled polarization to assist Schottky junction in modulating separation/extraction efficiencies of these charges. Ultimately, this multi‐effect coupled devices deliver impressive DC output of 7.3 V and 69.8 µA, outperforming similar coupled Schottky junction TVNGs. Besides that, its feasibility for multifunctional sensing and photodetection is also demonstrated. This study proposes an effective strategy for modulating performance while extending its functionality, which can expedite the development and potential application of advanced TVNGs.

The poor anode/electrolyte interface triggered by abysmal dendritic growth and hydrogen evolution reactions (HER) hinders the development of aqueous zinc‐ion batteries (AZIBs). Here, a highly efficient electrolyte is formulated with sucralose (Sucral) additive to refresh solvated structure and steer interfacial renovation, for building highly electronegative Cl‐modulated trinity effect in the bulk‐interface between electrolyte and electrode. Experiment results and theoretical studies jointly reveal that Sucral with highly zincophilic and hydrophilic hydroxyl groups can remodel primary Zn2+ solvation shell and interrupt strong H‐bond network from H2O molecules, thus boosting fast de‐solvation and restricting undesirable HER. Simultaneously, three highly electronegative chlorides in the adsorbed Sucral possessing hydrophobic features can enable a H2O‐poor electric double‐layer (EDL), thus remodeling the Zn surface against corrosion. Additionally, it realizes preferential exposure of the Zn (002) plane for helping uniform interfacial deposition. The synergy of the above factors achieves a prolonged lifespan of 3000 h (1.0 mA cm−2, 1.0 mAh cm−2), much better than that with Sucrose (Suc) electrolyte. The Zn//V2O5 full cell at 5 A g−1 also maintains enhanced stability of 1500 cycles with 160 mAh g−1. [ABSTRACT FROM AUTHOR]
