Abstract Nowadays, battery electric vehicles are increasingly used, from passenger cars to heavy-duty commercial vehicles, trains, and ships, all in an effort to reduce greenhouse gas emissions. In electric vehicles, battery capacity significantly affects their range and performance, but a larger battery also increases the vehicle’s mass and cost. This paper proposes parametric optimization of battery capacity and peak electric motor power for electric vehicles under different load types and vehicle capacities. A computational model of an electric vehicle is developed, with parameters such as battery capacity, payload, and peak motor power being variable. Using parametric More >

Abstract An eco-friendly one-pot hydrothermal method was developed to synthesize molybdenum disulfide/graphene oxide (MoS₂/GO) nanocomposites for high-performance supercapacitor applications. X-ray diffraction (XRD) analysis confirmed the presence of the MoS₂ crystalline phase, with reduced peak intensities upon GO incorporation, indicating suppressed crystallite growth. Scanning electron microscopy (SEM) revealed rod-like MoS₂ structures uniformly distributed across layered GO sheets, and energy-dispersive spectroscopy (EDS) confirmed the presence of Mo, S, C, and O elements. Raman and FTIR analyses verified strong interfacial interactions between MoS₂ and GO. Brunauer–Emmett–Teller (BET) measurements revealed a mesoporous structure with a specific surface area of ~31.7 m² g⁻¹ and… More >

Abstract Large-capacity energy storage batteries exhibit thermal behaviors markedly different from conventional cylindrical or pouch cells. Due to their multilayer electrode structure, they show pronounced anisotropy in thermal conductivity between through-thickness and in-plane directions. This results in uneven heat diffusion and internal–external temperature gradients that surface sensors cannot capture. Moreover, heat generation varies with temperature and state of charge (SOC) owing to changes in internal resistance. To address these challenges, an equivalent circuit and anisotropic electrothermal coupled model were established, with heat generation and transfer processes analytically derived. Parameter identification was performed through capacity calibration, specific More >

Abstract The design of foundations for high-voltage electrical network lattice towers depends on reliable prediction of resistance to uplift and lateral forces. Because foundation works contribute substantially to the total project cost, a clear understanding of ultimate pullout capacity and the associated failure mechanism is required to support safe and economical design. This paper presents a three-dimensional finite element investigation using PLAXIS 3D to quantify the influence of soil type (pure sand and sand with 8% fines), footing dimensions ((3.5 × 7), (5 × 10), (7.5 × 15)), relative compaction RC are 92% and 100%, and… More >

Abstract Addressing voltage violations and renewable energy absorption bottlenecks arising from high-penetration photovoltaic (PV) integration, this paper proposes a hierarchical optimisation architecture for a Hybrid Energy Storage System (HESS) based on microgrid-distribution network coordination to enhance collaborative regulation of energy storage across multiple microgrids. The methodology comprises a PV hosting capacity assessment model and an HESS operation model that accounts for power supply reliability, forming a two-layer planning framework that integrates distributed decision-making with centralized coordination. At the microgrid level, HESS capacity is determined to minimise the local comprehensive cost, while the allocation ratio between lithium-based More >

Abstract This study develops an optimized integrated system for full-capacity hot water supply in hotels by combining solar thermal energy and air-source heat pumps. Using a hotel in Wuhan as a case study, a four-season × four-occupancy multidimensional working-condition matrix was established. Dynamic simulation and multi-objective optimization were performed on TRNSYS-TRNOPT, with the cost-benefit ratio (CBR) as the core evaluation metric. Key parameters—including collector area, tilt and azimuth angles, heat pump capacity, and storage tank volume—were jointly optimized. Model calibration against measured data yielded a deviation of less than 8%. The results demonstrate that the optimized More >

Abstract Accurate diagnosis of liquid loading in gas wells is hindered by inconsistent criteria for identifying the critical liquid-loading condition and by reliance on subjective observation during the development of physical models. To address this issue, controlled laboratory experiments were conducted to investigate pressure fluctuations in gas–liquid two-phase flow under different flow regimes, with the aim of establishing a quantitative criterion to identify such critical conditions. High-frequency pressure signals were collected and analyzed using complementary ensemble empirical mode decomposition (CEEMD). Characteristic parameters describing slug flow, annular flow, and the critical liquid-loading condition were extracted accordingly, including More >

Abstract The custard apple fruit (Annona reticulata L.) is distinguished not only by its pleasant flavor and high nutritional value, but also by the presence of bioactive compounds in its pulp, particularly antioxidants, which may provide health benefits when consumed. However, in Nayarit this plant material is found in the wild, without agronomic management or conservation programs. Therefore, the purpose of this research was to evaluate several antioxidants in the pulp of custard apple fruits. Fruits were collected from four localities in Tepic, Nayarit (Jicote, Trapichillo, 14 de Marzo, and Tepic). Total phenolics, flavonoids, vitamin C, carotenoids,… More >

Abstract In response to the actual demands of the energy storage type organic Rankine power generation cycle, this study proposes a new type of jacketed shell and tube heat exchanger with integrated cold storage and heat exchange. N-tedecane is selected as the phase change material for cold storage, low-temperature water as the cold source, and R134a as the heat source. The phase change material for cold storage is filled inside the jacket tube of the heat exchanger. Cold fluid is introduced into the inner tube to cause the phase change material to condense and store cold.… More >

Abstract Mexican oregano (Lippia graveolens Kunth) is an aromatic species of high culinary and medicinal relevance. In Mexico, more than 40 taxa with characteristic aroma and flavor are commercially recognized as oregano, with L. graveolens being the most widely distributed and economically important. Despite its relevance, few domesticated or semi-domesticated cultivars exist, and wild populations remain the main source of raw material, raising concerns regarding sustainability and quality standardization. The essential oil and oleoresins of L. graveolens possess recognized bioactivity, including antioxidant, antifungal, antibacterial, and anti-inflammatory properties, largely attributed to phenolic compounds such as thymol and carvacrol. Given the… More >
