Authors: Zheng Yuanyuan , Wang Ning , Zhang Jianhua , Zhang Xiaobao , Yang Juanyu 
Published: October 2024

Abstract
The utilization of polymeric binders is indispensable in the implementation of silicon/carbon anode materials in high-energy-density lithium-ion batteries (LIBs). This necessity arises from their pivotal function in upholding structural integrity. However, current water-based binders solely focus on binder adhesion, neglecting the crucial interaction with the carbon material. In this work, a composite binder (CMC-CPAM-SBR) was constructed by combining Styrene Butadiene Rubber (SBR) with cationic polyacrylamide (CPAM) network binder with self-healing carboxymethyl cellulose (CMC). This innovative binder formulation was designed to enhance the performance of Si@C/graphite composite anodes. A capacity retention rate of 92.86% was achieved after 100 cycles, which represents the improvement over the performance of electrodes utilizing the CMC-CPAM binder, which only retained a capacity of 84.53% after the same number of cycles. A full battery with a capacity of 1992.8 mAh was designed, and the battery capacity remained at 80.6% of its capacity after completing 500 cycles. This research presents an effective technique for manufacturing high-performance anode materials.

Published: October 2024

Abstract
To study the influence of grinding parameters on the grinding force of semiconductor quartz disc based on the adhesive clamping method, an orthogonal experiment was designed to investigate the impact of grinding parameters on the grinding force. Based on the orthogonal test data, the influencing factors and parameter optimization of the grinding force are developed. The experimental results show that the order of influence of grinding parameters on the X-axis is feed speed > spindle speed > grinding depth, the sequence of effect on the grinding force in the Y-axis is grinding depth > feed speed > spindle speed, and the order of influence on the grinding force in Z-axis is grinding depth > spindle speed > feed speed. Therefore, using a higher spindle speed, a lower feed rate and a shallower grinding depth can play a role in reducing the grinding force. By improving the grinding parameters, the stability of quartz plate grinding based on adhesive technology is verified. It is found that adhesive is a more reliable clamping method, which ensures the processing quality of quartz plate and improves the working efficiency.

Authors: Sun Ningsong , Zhang Zhenmin , Li Yayun , Yang Chao 
Published: October 2024

Abstract
CO2 was one of the key factors that caused serious corrosion of petroleum equipment and facilities. Aiming to address the problem of serious pitting corrosion in the impeller of an oil pump in a CO2 flooding field, immersion, and electrochemistry experiments were comprehensively analyzed in this paper. The results showed that the corrosion rate of FV520B steel increased exponentially with the increase of pipeline transport pressure and flow rate (R2>0.9), and the potential shifted negatively. With the increase of pipe pressure, the corrosion directivity of the specimen surface gradually disappeared, showing a distinct pitting area and a comprehensive corrosion area. This was due to cavitation under high pipe pressure conditions.

Published: October 2024

Abstract
The synthesis of silicon quantum dots (SiQDs) via thermal pyrolysis is considered promising due to its cost-effectiveness. The etching process in this method has the potential to control the size of SiQDs precisely and has thus garnered attention. However, there are varying observations regarding the effect of etching duration on SiQD size. Additionally, the impact of dioxonium hexafluorosilicate (DH), a byproduct of the etching process, on the photoluminescence (PL) quantum yield (QY) of SiQDs remains unclear. This study investigates the effect of etching duration on the physical and optical sizes as well as the PLQY of SiQDs. The results indicate that extending the etching duration decreases the physical size of SiQDs, while the optical size initially increases slightly before decreasing. The SiQDs transition through three phases with increasing etching duration: oxidation removal, shallow over-etching, and deep over-etching. Both amorphous silicon (a-Si) in the oxidation removal phase and DH in the deep over-etching phase act as non-radiative recombination centers, thereby reducing the PLQY of SiQDs. Therefore, optimizing the etching duration to achieve the shallow over-etching phase is essential. This study provides new insights into the effects of etching duration on SiQD size and PLQY, aiding in the preparation of higher-quality SiQDs.

Published: October 2024

Abstract
Rapid global warming has caused drastic mass loss in Greenland’s peripheral glaciers and ice caps (GICs), contributing to a rise of global sea levels. To better understand future changes under different emission scenarios, we used the Open Global Glacier Model to simulate glacier dynamics and runoff changes from 2015 to 2100. The results show that their area and volume will decrease by 38.88% (SSP1-2.6) to 60.84% (SSP5-8.5) and 47.56% (SSP1-2.6) to 67.10% (SSP5-8.5) by 2100, with regions that have larger glacierized areas and are farther from the ocean experiencing less volume loss. Meanwhile, the predicted surface mass balance of Greenland’s peripheral GICs in 2100 is −0.58 ± 0.92, −1.18 ± 1.13, −2.04 ± 0.79 and −3.16 ± 0.96 m w.e. a−1 under four emission scenarios. The runoff under higher emission scenarios is larger than that under lower emission scenarios, with peak water occurring later in regions that have larger glacierized areas and are farther from the ocean.

Abstract
The reuse of treated wastewater in drinking water supply and irrigation emerges as a potent solution to address water scarcity. Recent years have witnessed a growing interest in wastewater treatment using ecological, non-toxic, and biodegradable materials. In this study, Austrocylindropuntia subulata was employed for the first time to adsorb a synthetic dye, methylene blue. The feedstock underwent pyrolysis followed by chemical activation using orthophosphoric acid, resulting in the formation of biochar. Characterization through SEM, XRD, and FTIR analyses reveals that the biochar surface possesses functional groups such as alcohol and amide. Microscopic images highlight a diverse array of particle shapes and sizes, along with varying proportions of calcium and carbon in the biochar. Adsorption tests demonstrate that the optimal mass of biochar is 0.5g, ensuring a remarkable 99.8% adsorption of methylene blue dye within a 30 minutes contact time. The findings of this study underscore the compelling adsorbent capabilities of biochar derived from the Austrocylindropuntia subulata plant, suggesting its potential as a valuable resource in wastewater treatment.

Abstract
This in-depth ethnobotanical study was conducted specifically in the Middle Atlas region of Morocco to document and analyze the use of medicinal and aromatic plants (MAPs) among local populations suffering from various chronic conditions. This survey involved 99 participants with gastrointestinal, cardiovascular, endocrine, urinary, gynecological, or similar diseases. The main objective was to draw up a complete inventory of the MAPs used, detailing their therapeutic indications and identifying any adverse effects associated with their use, whether through misapplication, overdosing, or interaction with other drugs taken by the patients. In the present, twenty MAPs species belonging to twelve distinct botanical families were identified. Among these plants, oregano (Origanum compactum) from the Lamiaceae family is the most widely used species, with a frequency of over 30%. Leaves were the most commonly used plant organ in traditional recipes (60.6%), whereas decoction was the most predominant preparation method (51.5%). This survey was conducted using questionnaires distributed in some pharmacies, and provided valuable data on MAP use practices, highlighting the predominance of certain plant species, their main therapeutic indications, and the preparation methods preferred by the Middle Atlas inhabitants to treat their ailments.

Abstract
This study aimed to evaluate the influence of the association between faba bean and cereal crops on the incidence and severity of black aphids, weed control, and faba bean yield in Meknes region, Morocco. Regression and correlation analyses were performed to examine the relationship between different parameters. The results showed that the combination of faba bean with cereals significantly reduced black aphid infestation, weed density, and biomass compared to faba bean alone. The present study also revealed a positive correlation between reduced aphid incidence and improved faba bean yield. Analyses also revealed significant correlations between weed density and aphid incidence/severity as well as notable associations between faba bean crop biomass, weed biomass, and faba bean yield. These findings underscore the importance of crop associations in enhancing the resilience and productivity of faba beans through integrated aphid and weed management. They highlight the complexity of the interactions between aphids, weeds, and faba bean crops, requiring a holistic approach to understand their impact on crop yield.

Published: October 2024

Abstract
In the study assessing the impact of global change on hydrosystems, particularly water resources, calibrated and validated tools are deemed crucial for accurate representation of the area’s characteristics. The Soil and Water Assessment Tool “SWAT” model is identified through literature review as well-suited for evaluating changes in land use and climate effects on water balance components. Applied to the Upper Oum Er Rbia watershed and its sub-basins, namely Oum Er Rbia, Srou, and Ouaoumana, the SWAT model demonstrates its effectiveness over the 1982-2019 period. Employing the sequential uncertainty adjustment method (SUFI-2) in SWAT-CUP software for calibration and validation, the model achieves good performance in simulating river flows. Statistical tests, including “R²,” “NSE,” “PBIAS,” and “RSR,” reveal consistent accuracy across various stations. The positive outcomes affirm the SWAT model’s operational capability for diagnostic assessments, risk evaluation, adaptation measures, and potential future projections in these three sub-basins.
The impact of converting to drip irrigation on water use valuation
Authors: Hamidi Bouchra , Bourkhiss Brahim 
Published: October 2024

Abstract
The issue of irrigation water uses and conservation were mains of significant importance due to the increasing scarcity of water resources. Recognizing this situation, Morocco initiated the National Program for Water Saving in Irrigation, which focuses on two key components: the conservation and valuation of irrigation water. The program aims to transition surface irrigation systems into localized irrigation systems. This study endeavors to estimate and analyze the impact of converting to drip irrigation on both the financial and agronomic valuation of irrigation water for onion cultivation in the Fez-Meknes region.
The research is based on a sample of 63 farms selected from a population engaged in onion cultivation, consisting of both drip irrigation and surface irrigation practices. Surveys were conducted for each farm to gather both quantitative and qualitative information, spanning the crop years 2022 and 2008. To assess the program’s impact on irrigation water valuation, the double difference method was applied to our sample. Furthermore, an ordinary regression model, implemented using GRETL software, was employed to analyze the determinants of irrigation water valuation.
The results obtained through the double difference method reveal a positive average impact of the program on farmers’ financial and agronomic valuation, estimated at 3.2 DH/m3 and 5.58 kg/m3, respectively.

Published: October 2024

Abstract
This research investigates how land use and cover the affect land surface temperature in Kenitra. It employs Geographic Information System techniques and remote sensing methods to monitor and control surface temperature changes. The present study integrates remote sensing and geographic information system to process satellite images. Furthermore, it focuses, also, on analyzing land surface temperature and its correlation with land cover changes over three time periods (1989, 2000, 2020) using landsat satellite data. Thus, supervised classification is employed to map these changes and derive urban heat islands from thermal band data.
This study provides a comprehensive evaluation of the relationship between land use and land surface temperature. It utilizese a landscape dynamics assessment based on multi-source and multi-sensor remote sensing technologies. Specifically, the study uses landsat satellite data (TM for 1989 and OLI-8 for 2002 and 2020) to assess the effects of land use and land cover changes on land surface temperature distribution in the Kenitra city. Spatial and statistical analyses are performed by comparing maps from remotely sensed data generated using geographic information system. Therefore, these analyses reveal various changes in the kenitra region between 1989 and 2020.
The primary changes observed include an increase in built-up areas and bare ground with a decrease alongside in natural areas (vegetation, etc.). The average temperatures in 1989, 2002, and 2020 were 29°C, 31.05°C, and 32°C, respectively.
The obtained results are valuable for planning and managing climate scientists, land-use planners, and researchers focusing on sustainable urbanization areas. The study’s findings will assist urban planners and policymakers in adopting appropriate measures for sustainable planning in the city to mitigate the adverse effects of land surface temperature.
Variability of seasonal temperature from 1990 to 2020 within Oum Er Rbia hydraulic basin (Morocco): Study of trends and anomalies
Authors: Hamid Meriem , Ghachi Mohamed El 
Published: October 2024

Abstract
The fifth report of the Intergovernmental Panel on Climate Change (IPCC) indicates that global temperatures have increased during the 20th century. In Morocco, numerous studies have unveiled that the nation has been contending with the effects of global warming for several decades, attributed to its geographical location. The studies have mainly focused on the evolution of rainfall and the recurrence of droughts. Nevertheless, temperature variations remain less addressed, especially at large spatial scales. This paper aims to study the seasonal temperature variability in the large hydraulic basin of Oum Er Rbia, focusing on its anomalies and trends as well as identifying their impacts on the basin’s territory. Indeed, the large basin of Oum Er Rbia occupies more than 48,.000 km2 and is characterized by an arid to semi-arid climate. Its water resources are important and play an essential role in the country’s socio-economic development. This basin is well-known for its agricultural activity. Although its water and economic potential are significant, the great basin is considered vulnerable to climatic variations, which strongly condition its development. Considering the significance of temperature trends within the framework of global warming, this current study delves into the topic of seasonal temperature variability within the expansive hydraulic basin of Oum Er Rbia. Based on statistical analysis using the temperature anomaly index and the Mann-Kendall trend test, this study reveals that strong interannual variability marked the evolution of seasonal temperatures during the period of 1990-2020, with a remarkable upward trend during the autumn and spring. When the temperature increase, the temperature increases in turn: thus, the negative impacts affect both water resources and the agriculture sector, which suffers from the combined effect of increased evapotranspiration and reduction of irrigation water.

Published: October 2024

Abstract
In the context of climate change, this study focuses on the impact of heatwaves, which have become the dominant meteorological phenomenon in terms of duration and intensity. The objective is to understand the temporal variation of temperatures in the urban domain, highlighting thermal differences on an hourly scale. The city of Kasba Tadla, located in the Tadla plain in Morocco, is at the core of this research. This rapidly expanding urban area is traversed by the Oum Er-rbia River. The selection of this region allows for a specific analysis of the climate challenges a rapidly growing city may face. The methodology relies on a network of four fixed meteorological stations installed in the city of Kasba Tadla. Temperature measurements were taken on an hourly timescale during the summer of 2022. This approach enables a detailed analysis of temperature variation based on building density and the presence of vegetation in different neighborhoods. The results highlight a significant temperature variation within the city, emphasizing the impact of building density and vegetation on this phenomenon.
Influence of interface on nondeformable micropolar drop migration
Authors: Salem Ahmed G 
Published: October 2024

Abstract
In this article, an analytical approach is considered to study the issue of specifying Stokesian motion due to a micropolar sphere drop translating at a concentric instantaneous position within a spherical fluid–fluid interface that divides two immiscible fluids, one of which is bounded and the other is unbounded. Here, the focus is on the situation where there are two microstructure-related fluid phases (micropolar fluids) out of the three. The motion is considered to have low Reynolds numbers; thus, the drop’s surface and fluid–fluid interface have insignificant deformation. General solutions to the slow axisymmetric motion of the micropolar/viscous fluid in a spherical coordinate system are obtained based on a concentric position. Boundary conditions are fulfilled at the drop’s surface and the fluid–fluid interface. Findings indicate that the normalised hydrodynamic force increases monotonically as the droplet-to-interface radius ratio increases, acting on a moving micropolar sphere droplet and becoming unlimited when the drop’s surface touches the fluid–fluid interface. The numerical findings for the normalised force operating on the micropolar sphere droplet at different values of the suitable parameters are introduced in both graphical and tabular form. Our numerical findings are compared with the suitable data for the special cases stated in the literature. The current investigation of the study has practical applications in many domains of industrial, biological, medicinal, and natural processes, for example, liquid crystals, polymeric suspensions, muddy fluids, liquid–liquid extraction, raindrop formation, blood cells moving through a vein or artery, suspension rheology, sedimentation, and coagulation.
