Abstract The thin films and powders of PbS, PbSe, and PbSe and PbS_0.5Se_0.5 have been obtained by chemical precipitation method. The X-ray spectra of the obtained thin layers were obtained through the"Miniflex 600" diffractometer, and elemental analyses were performed. Thermogravimetric analyses of the powders of all three compounds were conducted in the temperature range of 20-800°C using the "NETZSCH STA 449 F3" apparatus. It has been determined from the X-ray spectra that the angular positions of all the peaks of PbS, PbSe, and PbSe and PbS_0.5Se_0.5 thin layers coincide with the positions of the corresponding diffraction peaks More >

Abstract Powdery mildew of cucumber (Cucumis sativus L.) is a destructive disease caused by Podosphaera xanthii (Castagne) U.Braun & Shishkoff. This study aimed to investigate the antifungal effect of extracts of Ulva lactuca, Spirulina platensis, and Nostoc muscorum against P. xanthii and to improve the physiological and morphological traits of cucumber under commercial greenhouse conditions. The chemical composition of the individual extracts from U. lactuca, S. platensis, and N. muscorum was analyzed utilizing High-performance Liquid Chromatography (HPLC) and Gas Chromatography/Mass spectrometry (GC/MS). Cucumber plants were sprayed twice with 5% of the crude extracts of U. lactuca, S. platensis, and N. muscorum and their mixture (U. lactuca, S. platensis, and N. muscorum).… More >

Abstract Hot isostatic pressing (HIP) is often utilized to obtain laser powder bed fused (LPBF) Ti-6Al-4V with good mechanical properties. To uncover the underlying mechanisms by which HIP improves the mechanical properties, several mechanisms are considered and examined against experimental data sets available in the literature. The results suggest that HIP improves mechanical properties by both reducing defect sizes below a critical threshold and altering the microstructure surrounding defects. Based on these findings, a pore healing model was developed, and optimized HIP processing parameter range (temperature, pressure, and soaking time) were proposed. Severe plastic deformation driven… More >

Abstract Ag/Al₂O₃ powders are highly effective catalytic materials utilized in the epoxidation of ethylene to produce ethylene oxide. One of the critical challenges in this catalytic process is the stability of nano-sized Ag particles, especially during high-temperature catalysis. However, this issue can be effectively addressed through in-situ reaction synthesis. To gain a deeper understanding of the underlying mechanisms, the phase transformation process and the thermodynamic mechanism of the oxidation reaction in the Ag/Al₂O₃ system have been investigated using first-principles thermodynamic calculations in conjunction with traditional thermodynamic data. These calculations, whose accuracy has been verified, provide valuable insights into… More >

Abstract Machine learning models can predict material properties quickly and accurately at a low computational cost. This study generated novel hybridized nanocomposites with unsaturated polyester resin as the matrix and Areca fruit husk fiber (AFHF), tamarind fruit fiber (TFF), and nano-sized coconut shell powder (NCSP). It is challenging to determine the optimal proportion of raw materials in this composite to achieve maximum mechanical properties. This task was accomplished with the help of ML techniques in this study. The tensile strength of the hybridized nanocomposite was increased by 134.06% compared to the neat unsaturated polyester resin at… More >

Abstract Powder based high speed sintering (HSS) improves the printing efficiency compared to SLS printing. The shortened layer time for HSS requires quick melting and solidification of powders, which is a big challenge for traditional printing powders materials, especially the viscous elastomers. Herein, a dynamic cross-linked polyurethane containing Diels-Alder bonds (PUDA) was synthesized at kilo scale and used for HSS. The incorporation of dynamic DA bonds into PU enables the dissociation of the polymer chain under IR light heating, and will lead to fast relaxation, diffusion and dis/re-entanglement, addressing the problem of incomplete sintering and weak… More >

Abstract In this study, Opuntia ficus-indica cladode powder (OFIC), locally sourced from Rabta in Tunis, was utilized as a novel, eco-friendly adsorbent in both raw and iron(III) chloride-modified forms. The presence of iron in the modified material was confirmed by X-ray fluorescence spectroscopy (XRF). The neat and modified biomass were characterized by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM), and their usefulness as adsorbent for cationic Neutral Red (NR) and anionic Congo Red (CR) dyes were explored under batch conditions. Equilibrium studies revealed that the iron-modified Fe(OH)_x@Cellulose adsorbent exhibited… More > Graphic Abstract

Abstract Silicone rubber (SR) exhibits superior breathability and high-temperature resistance. However, SR is prone to degradation under extreme heat or combustion, limiting its effectiveness in mitigating secondary hazards. In this study, phosphate glass powder was used to calcinate zinc borate, lanthanum oxide, and cerium oxide. Methylphenyl polysiloxane was then grafted onto the surface of the glass powder, resulting in the modified powders designated as Methylphenyl polysiloxane-grafted zinc borate-modified phosphate glass powder (GF-ZnBM), Methylphenyl polysiloxane-grafted lanthanum oxide-modified phosphate glass powder (GF-LaM), and Methylphenyl polysiloxane-grafted cerium oxide-modified phosphate glass powder (GF-CeM). The modified powders were subsequently incorporated into… More > Graphic Abstract

Abstract Highly flame-retardant bio-based composites were prepared in this study. Firstly, glucose-citric acid (GC) resin was synthesized through the interaction of glucose and citric acid derived from agricultural and forestry sources. Polyvinyl alcohol (PVA) served as a toughening agent, whereas walnut shell powder (WSP) functioned as a filler in the formulation of a thermosetting bio-based GC-PVA-WSP (GCPW) composite with GC resin. The findings demonstrated that boric acid increased the limited oxygen index (LOI) value of GCPW to 33%, while simultaneously diminishing its total smoke production (TSP) by 99.9%, and achieving a flame retardant index (FRI) of More > Graphic Abstract

Abstract This paper investigates the application of Direct Current Atmospheric Plasma Spraying (DC-APS) as a versatile thermal spray technique for the application of coatings with tailored properties to various substrates. The process uses a high-speed, high-temperature plasma jet to melt and propel the feedstock powder particles, making it particularly useful for improving the performance and durability of components in renewable energy systems such as solar cells, wind turbines, and fuel cells. The integration of nanostructured alumina (Al₂O₃) thin films into multilayer coatings is considered a promising advancement that improves mechanical strength, thermal stability, and environmental resistance.
