Published: October 2024

Abstract
A new setup is being developed for calibrating CCD/CMOS sensors and cameras, and measuring spectrophotometric quantities in both point-wise and imaging modes. The setup includes a laser-driven light source (LDLS), double-grating monochromator, and an integrating sphere with specific design for two-dimensional (2D) spectrophotometric measurements of complex samples and spectral responsivity calibration of digital imaging sensors and cameras in the visible to near infrared (VIS-NIR) region. The setup can cover a spectral range from 250 nm to 2000 nm with relatively high radiance. The study presents optimization and validation work in the visible through NIR spectral range, up to 1000 nm. Preliminary experiments suggest improved accuracy and lower uncertainties for better metrological performance and sophisticated applications. The developed instrument promises a variety of novel applications while suppressing systematic errors and inaccuracies. The presented measurements results include the validation of 2D spectral reflectance/transmittance measurements in the 360-1000 nm spectral region using selected homogenous standards. Additionally provided are the findings of demonstration measurements for 2D spectral transmittance and the CCD camera’s spectral responsivity within the same spectral range.

Published: October 2024

Abstract
For the calibration of the radioluminescence detection systems developed within 19ENV02 RemoteALPHA EMPIR project, two purely optical radiation-based devices, which accurately simulate the radioluminescence induced in air nitrogen by an alpha-particle emitted from a planar radionuclide-based sample, were designed, manufactured, and characterized. The variable low-photon flux radiance sources are based on a combination of two integrating spheres and LEDs as UV-A and UV-C radiation sources. The calibrated maximum integrated photon radiances are 7.5·1011 s−1·m−2·sr−1 for the UV-A (CWL = 337 nm, FWHM = 10 nm) and 3.0·1010 s−1·m−2·sr−1 for the UV-C (CWL = 260 nm, FWHM = 20 nm) spectral range with relative standard uncertainties (k=1) from 5 % (UV-A) to 8 % (UV-C).

Published: October 2024

Abstract
Facile and efficient radiative daytime cooling technology is still a huge challenge. In this paper, we proposed an eco-friendly, facile, efficient superhydrophobic radiative daytime cooling film composed of polydimethylsiloxane, nano TiO2, and nano SiO2. This radiative daytime cooling film could have about 15°C cooling of Al sheet, 9°C cooling for the building model on a sunny summer day, and 8°C cooling for the building model on a cloudy summer day, respectively. This method is promising to be used in building cooling fields.

Authors: Huang Jiwei , Lv Yang , Wang Anyang , Xia Wei , Zhou Quan 
Published: October 2024

Abstract
To quickly realize the optimal design of the cap-shaped structure, an optimization design method of composite cap-shaped pillar structure based on combined kernel function Gaussian process was proposed. First, the shortcomings of two kernel functions representing different linear characteristics of data in model construction were analyzed, on which a new combined kernel function was constructed. Based on the finite element numerical simulation results, a database with the web thickness, web height, fiber volume, and ultimate bearing capacity of the cap-shaped structure was constructed. Then, a Gaussian process model based on the combined kernel function was established and the model parameters were trained by the maximum likelihood method. Finally, taking the ultimate bearing capacity per unit volume as the optimization objective, the artificial fish swarm algorithm was used to quickly obtain the structure design parameters under the optimal objective function, and the simulation results were compared with the initial design parameters. The results showed that the method proposed in this paper can optimize the structure performance, improve the design efficiency, and meet the engineering design requirements.
Preparation and mechanical properties of Al-doped TiC films
Authors: Zhang Haifeng , Du Lifei , Wang Haonan 
Published: October 2024

Abstract
Al-doped TiAlxC films were prepared on different substrates (single crystal Al2O3 (0001), stainless steel, and silicon wafer substrates) by co-sputtering, and microstructures and corresponding mechanical properties of TiAlxC films were tested and analyzed. The results indicate that the microhardness of the prepared TiAlxC films would decrease with the increased doping amount of Al while the corresponding friction coefficient would increase. With the increase of Al doping, the excess Al hinders the growth of the nanocrystalline phase in the TiAlxC film, thereby affecting the hardness and wear resistance of the TiAlxC film. When the Al doping is 4.1 at%, the hardness of the film reaches 2, 890 HV, while the friction coefficient is 0.2, indicating that a small amount of Al plays a role in solution strengthening the film. Therefore, the mechanical properties of the Al-doped TiAlxC films could be tailored by the doping amount of Al.

Authors: He Rui , Bai Xue , Wei Aijia , Niu Yuxin , Li Xiaohui 
Published: October 2024

Abstract
The low-cost lithium iron manganese phosphate anode material has a 15% higher energy density than lithium iron phosphate, and it has received wide attention in recent years. However, the poor electronic/ionic conductivity of lithium ferromanganese phosphate leads to poor power performance, which makes it difficult to meet the needs of practical applications. In this study, a V-doped LiMn0.2Fe0.8PO4(LFMP) material is designed and prepared, and every particle is coated by a uniform carbon layer. The V-doped LFMP material shows better rate performance and cycle performance. When the optimal vanadium doping amount is 0.01, the specific discharge capacity of the material is 164.0 mAh/g at 0.1 C.
Modulation of photoluminescence properties of transition metal dichalcogenides through temperature and Au/Ag nanoparticles
Authors: Wang Caiyun , Gao Yihua 
Published: October 2024

Abstract
Transition metal dichalcogenides (TMDCs) attract significant attention because of their remarkable optical properties. Nowadays, the light emission efficiency of TMDCs is still inferior. Temperature and plasma resonance effects can be important approaches in the modulation of their luminescence performance. Here, multilayer WSe2 and monolayer MoSe2 were synthesized. Under the temperature control system, two photoluminescence (PL) peaks are observed from multilayer WSe2. The higher-energy PL peak results from K-Γ indirect band gap transition, which is then demonstrated by the first principle calculation. Otherwise, PL enhancement is realized on monolayer MoSe2 decorated with Au nanoparticles. The PL of WS2 is inhibited by hybridization with Ag nanoparticles.
Analysis of cracking failures in water-cooled wall fins and thermal peaking unit mitigation strategies
Authors: Zhang Yansheng , Zhang Lei , Li Guang , Duan Zhixiang 
Published: October 2024

Abstract
The causes of leakage in the submitted superheater tubes were analyzed using the analysis of macroscopic morphology, chemical composition, and metallography. The analysis results indicate that the chemical composition of the failed superheater tube is within the standard range, and the metallographic structure is ferrite + pearlite, with no abnormalities in the metallographic structure. The main reason for the failure of water-cooled wall tubes and superheater tubes may be the formation of fatigue cracks on the inner and outer walls of the superheater tubes under cyclic stress. As the two fatigue cracks grow and converge, penetrating cracks form, ultimately leading to the initial leakage of the superheater tubes. In addition, the excessive depth of the weld pool in the fins of the superheater tube is another crucial factor that promotes accelerated cracking of the superheater tube. It is recommended that power plants reasonably regulate the temperature difference fluctuation rate of boilers to prevent similar failure accidents from occurring.
Effect of deformation degree on the mechanical properties of Al-Zn-Mg-Cu alloys: an industrial study
Authors: Yu Mingyang , Shi Guohui , Wen Kai , Yan Hongwei 
Published: October 2024

Abstract
Hot deformation is a crucial process in the manufacturing of aluminum alloy products, as its parameters exert a profound influence on the ultimate properties of the alloys. This work reports on the Al-Zn-Mg-Cu alloys at a deformation temperature of 450°C, a deformation rate of 5 mm/s, and deformation degrees of 50% and 90% in industrial settings. Following that, an extensive assessment of the alloys’ mechanical characteristics, including their fracture toughness, tensile strength, and fatigue performance. Furthermore, a quantitative analysis of the microstructure was undertaken using OM and EBSD, which revealed that both the average and sub-grain sizes of the two alloys exhibited comparable characteristics. However, the recrystallization fraction showed a difference, with the alloy deformed to 90% exhibiting a higher fraction than the alloy deformed to 50%, while these recrystallized grains are distributed in chains. With the increase of deformation degree from 50% to 90%, the yield and ultimate strengths increase slightly. The opposite law is demonstrated by fatigue crack propagation resistance and fracture toughness. Put otherwise, compared to the alloy deformed to 50%, the alloy deformed to 90% exhibited a faster rate of fatigue crack propagation and a lower fracture toughness. In summary, this research examines how the degree of deformation affects the mechanical characteristics and microstructure of Al-Zn-Mg-Cu alloys.

Published: October 2024

Abstract
Solar energy as a clean, renewable energy source is perceived as a potential remedy to the environmental and climate degradation caused by fossil fuels. However, the surface contamination severely diminishes the photovoltaic conversion efficiency of solar cells. Liquid-repellent coatings that combine transparency and durability could be candidates for self-cleaning application of solar cells. Herein, a smooth liquid-repellent coating (SLRC) was developed by synergizing organosilicon and fluorine and was cured at room temperature. Owing to the low-surface-energy groups and flexible chains enriched on the SLRC surface, as well as cross-linking reactions and functional additives within the SLRC matrix, it exhibited liquid-repellency and UV-shielding properties. Moreover, SLRC could be applied to solar cells by spraying methods and displayed efficient self-cleaning properties. Finally, the adhesion strength and durability of SLRC were also verified, confirming that it had great potential for application in solar cells, opening the avenue for the development of self-cleaning coatings.
Effect of edge distance-diameter ratio on pin-bearing strength of TC18 by laser melting deposition
Authors: Chen An , Chen Xianmin , Zang Weifeng 
Published: October 2024

Abstract
This paper presents an experimental study on the pin-bearing characteristics of TC18 titanium alloy produced by laser melting deposition. Two types of specimens with edge distance-to-diameter ratios (e/D) were manufactured for pin-bearing tests. The S-Basis values of bearing strength are calculated based on statistical analysis of experimental data. The results indicate that the S-Basis value of bearing ultimate stress with e/D =1.5 specimens is 1648.12 MPa, and the S-Basis value of bearing ultimate stress is 1967.89 MPa for e/D =2.0 specimens. The S-Basis value of bearing ultimate stress for e/D=2.0 specimens is higher by 19.4% than that of e/D=1.5. The test result showed three different failure modes: shear-out, cleavage, and bearing. Each failure mode depends on the specific hole edge geometry adopted. The proportion of shear-out failure for e/D=1.5 samples is more than for e/D=2.0 specimens.

Abstract
To effectively combat marine biofouling, biomimetic anti-fouling coatings have garnered widespread attention as a novel anti-fouling method. Based on this biomimetic concept, this study adjusted the electrospinning process parameters and selected different solvent systems to effectively modify the surface morphology of poly (ॉ-caprolactone) (PCL) nanofiber coatings, developing a non-toxic anti-fouling smooth surface. These biodegradable slippery liquid-infused porous surfaces (SLIPS) coatings offer a simple way to prepare maritime anti-fouling coatings in an eco-friendly manner. They can withstand a variety of liquid, material, and microbiological contaminations.
Effect of bath temperature on corrosion resistance of electroless Ni-P coating on 5A90 Al-Li alloy
Authors: Wang Henan , Zhang Yangyi , Feng Changjie 
Published: October 2024

Abstract
The Al-Li alloy exhibits outstanding characteristics, including remarkable specific strength, elevated specific stiffness, and heightened susceptibility to localized corrosion. Electroless Ni-P coating is extensively applied over the appearance of aluminum alloys to enhance their corrosion resistance. Electroless Ni-P coating was applied to 5A90 Al-Li alloy at various plating temperatures for the study presented in this publication. The coating’s surface, composition, and cross-sectional morphology were examined using SEM/EDS. The corrosion behavior of coating was studied using the potentiodynamic polarization curve. Results showed that coating on the surface of 5A90 Al-Li alloy was uniform and smooth. Ni and P elements were evenly distributed in the coating. The thickness of coatings at 80°C, 85°C, 90°C and 95°C was about 3.98 μm, 5.5 μm, 11.2 μm, and 10.29 μm, respectively. As the temperature of the bath increased, the corrosion resistance of the coating first increased and afterward decreased. The corrosion resistance of the coating might be correlated with its thickness.
Capacitive behaviors for surface-sulfonated polyaniline nanofibers in different acidic electrolytes
Authors: Liu Jiahui , Qin Zongyi 
Published: October 2024

Abstract
Unique surface-sulfonated polyaniline nanofibers (PANI-S) were fabricated through one-pot polymerization to evaluate the feasibility of their applications as electrode materials for high-performance supercapacitors that can be operated in relatively weak acidic electrolytes. Benefiting from the self-doping effect and improved dispersion in aqueous solution for the nanofibers, as well as the effective buffering function of the electrolyte, the PANI-S exhibits excellent capacitive performance across a broad pH value range in acidic electrolytes. More clearly, the specific capacitance of the PANI-S remains remarkably stable, ranging from 752.4 to 754.4 F g−1 at a scan rate of 5 mV s−1 and from 575.4 to 536.8 F g−1 at a current density of 1 A g−1, as the pH value of the electrolyte varies from 0 to 6. However, the capacity retention rate of PANI-S gradually decreases from 79.2% to 37.2% as the current density increases from 1 A g−1 to 20 A g−1, with the pH of the buffered solution increasing from 0 to 6. The excellent electrochemical activity in low acidic electrolytes for PANI nanofibers can be attributed to the compensation effects of the self-doped local proton reservoir.

Published: October 2024

Abstract
The hypersonic craft necessitates significant advancements in thermal shielding to safeguard against the extreme aero-thermal environments encountered during flight at hypersonic speeds in near space or upon reentry from space. Carbon fiber-reinforced ceramic matrix composites (FRCMCs) have attracted increasingly interesting attention as advanced structural materials for application in thermal protection. The reactive melt infiltration (RMI) process is preferred for the preparation of FRCMCs because of its low cost and short processing time. However, the RMI process includes the complex interplay of melt flow, reaction dynamics, and thermal fields, with existing models failing to accurately predict these processes due to their uncoupled nature and neglect of pore structure changes. This study introduces a coupled model that integrates mass transfer flow, chemical reaction, and heat transfer, incorporating variable pore structures to more accurately evaluate the RMI process. This approach allows for a comprehensive assessment of internal pressure, temperature, and porosity changes during silicon infiltration into porous media, marking an improvement over the previous model. The model has been validated for use in predicting the exotherm of RMI processes. In conclusion, this coupled model presents a promising avenue for enhancing the fabrication of FRCMCs, either considering the melt infiltration from multiple locations in the RMI process or adjusting the pore structure at the infiltration location to larger pores.

Published: October 2024

Abstract
With the conjunction of clean energy generation and electric cars, the power distribution network is gradually shifting from a traditional one-way radiative network to an active network. Coordinated control of these controllable elements of “source-grid-load-storage” can improve the operating voltage level and economic benefits, and reduce the load peak and off-peak difference. A collaborative dispatch model for active power distribution networks including PV-storage-charging-compensation is constructed in this paper, with the goal of minimizing network losses and PV curtailment costs. The cone transformation is used to handle non-linear constraints of power flow. Compared with existing ordered charging control methods, the constructed model can maximize the control efficiency of the distribution grid, enhance the PV absorption capacity, and effectively slow down the upgrading and renovation of the distribution network.

Published: October 2024

Abstract
“Bayoud”, a vascular disease caused by the soilborne fungal pathogen Fusarium oxysporum f. sp. albedinis (Foa), is the principal enemy of palm trees that puts at stake the future of the date palm industry in Morocco. The parasite attacks the palms through the roots and colonizes the entire vascular system, leading to wilt and ultimately palm death. Effective disease management is a major step towards the success of all sustainable development projects in the oasis. This review delineates diverse strategies for managing Bayoud disease, including prophylactic measures, chemical and cultural controls, genetic selection for resistant varieties, and exploration of biochemical and molecular markers. An integrated management approach was proposed that underscores early detection, sustainable agricultural practices, genetic resistance, biological control, community involvement, and continuous research and development. To contain the disease in already-infested areas and prevent its spread to new date palm plantations in oases.
Analysis of the determinants of the regeneration and growth of Cedar Atlas (Cedrus atlantica (Endl.) Manetti ex Carrière), an endangered endemic taxon in Morocco-Case of the Middle Atlas forests
Authors: Laaribya Said 
Published: October 2024

Abstract
In the present study, the Azrou cedar Atlas forest (Cedrus atlantica), taken as a case study of the Middle Atlas forest, show a regressive evolution both in time and in space. Although this forest has been the subject of several successive regeneration attempts, its condition is far from satisfactory.
The present study focuses on a statistical and Correspondence factor analysis (CFA) to highlight the main determinants of this regeneration and Cedar Atlas growth. The results obtained revealed three classes of regeneration, namely (1) a group of poor regeneration, (2) a group of no regeneration, and (3) a group of average to good regeneration. Indeed, the regeneration of Cedar Atlas forests is linked to certain biophysical and socio-economic descriptors. Analysis of variance (ANOVA), Scheffé test and stepwise regression showed also that the soil depth, stand density, and basal area are the determinant variables that best explain the Atlas cedar growth.
To this end, a profound reflection on the vectors of change must be imposed in order to lead to the conservation and sustainable management of Cedar Atlas forests in Morocco. New approaches to forest management are needed.
