Abstract Additive Manufacturing, also known as 3D printing, has transformed conventional manufacturing by building objects layer by layer, with material extrusion or fused deposition modeling standing out as particularly popular. However, due to its manufacturing process and thermal nature, internal voids and pores are formed within the thermoplastic materials being fabricated, potentially leading to a decrease in mechanical properties. This paper discussed the effect of printing parameters on the porosity and the mechanical properties of the 3D printed polylactic acid (PLA) through micro-computed tomography (microCT), computational image analysis, and Charpy impact testing. The results for both… More >

Abstract The evaporation technique fabricates solar cells using the Cu(In, Ga)Se₂ (CIGS) absorber. This technique has strong limitations in preparing this absorber in a large area, necessitating the electrodeposition technique. However, the morphology and crystallinity of this absorber need to be sufficiently adequate to guarantee proper collection of charge carriers since a cauliflower-type growth is favored. This underscores the need for modifications during the synthesis, thermal treatments, and post-synthesis to improve the morphology and crystallinity, a complex and significant aspect of our research. This work discusses the structural, atomic composition, morphological, and optical results obtained for samples More >

Abstract In this paper, the effect of sulfur substitution by arsenic on the structural, optical properties of thin films of the trivalent chalcogenide Se₆₆S_44-xAs_x at different concentrations (where x = 0, 8, 16, and 24 at %) was studied. Thin films with a thickness of (300±10 nm) were prepared using thermal evaporation of bulk samples. Structural examinations were performed using XRD and AFM techniques. All the studied film samples were amorphous in structure and the intensity of the crystalline parts was high in the range of 10-40. Also, in Atomic Force Microscopy (AFM). It was found that… More >

Abstract Silicon nitride (Si₃N₄) ceramics with outstanding comprehensive properties, have become important candidate materials for components like radomes and antenna windows. In this study, the vat photopolymerization (VPP) technique was used to fabricate Si₃N₄ ceramic radomes. Our research centered on optimizing the curing properties of ceramic slurries and precisely regulating the comprehensive properties of the ceramics. Several methods were proposed to modify the curing depth of Si₃N₄ ceramic slurry, including thermosetting resin coating, sintering aid coating, oxidation coating, double coating, etc. Moreover, a pore-forming agent modification method was also proposed, which enabled the VPP printing of Si₃N₄ ceramic More >

Abstract With the advancement of the personalised medicine industry, multi-material targeted drug delivery systems have garnered significant attention due to the higher drug bioavailability and synergistic effects of combined drug therapies. However, the fabrication throughput of such systems often fails to satisfy the demands of clinical applications. Volumetric printing, distinguished by its remarkable capability for rapid fabrication, presents a promising approach for fabricating these systems. Nevertheless, during volumetric printing, formed parts are prone to displacement relative to their intended locations due to variations in ink density, viscosity, and other factors, resulting in geometric distortion and complicating… More >

Abstract This study examines the temperature field distribution characteristics and temperature effects during the prefabrication of composite box girders with corrugated steel webs (CBGCSWs), aiming to provide practical recommendations for controlling temperature-induced cracking and technical guidance for concrete mix proportions and placement processes. Based on field measurement data, a three-dimensional finite element model was developed to simulate the temperature effects at critical locations during the prefabrication phase. By varying the concrete mix proportions, initial casting temperature, and ambient temperature, the study elucidates the variation patterns of the temperature field during precast placement. The results show that… More >

Abstract The work deals with cellulose paper filled with nanocellulose and SrAl₂O₄:Eu,Dy oxide phosphor. It was found that both nanocellulose and oxide improve the tensile strength of the composites obtained. The samples with the oxide demonstrate a long-lasting photoluminescence (PL) under sunlight and ultra-violet (UV) illumination. Room-temperature the PL spectra reveal a wide multicomponent band spreading over all the visible spectral regions. The short-wavelength part of the band is ascribed to the cellulose-related luminescence, while the long-wavelength PL component with maxima near 540 nm corresponds to the luminescence of the SrAl₂O₄:Eu,Dy phosphor. The dependency of the PL… More > Graphic Abstract

Abstract This work reports a soft chemistry approach for the synthesis of magnesium oxide nanoparticles (MgO) incorporated in a polyaniline (PANI) matrix to give PANI/MgO nanocomposite. Using spin coating method, three different percentages of MgO/PVC (1, 2, and 3% in wt.%) were deposited on glass substrates. These films of PANI/MgO nanocomposite were characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), and UV-visible spectroscopy. The results of the XRD pattern revealed the embedding of MgO nanoparticles in the PANI matrix with cubic phase, with the average size of nanoparticles varying from 35.12 to 59.55 nm. The… More >

Abstract Zinc telluride (ZnTe) nanocrystals (NCs) have generated the interest of researchers as an electrode material in hybrid light emitting devices (HLEDs) due to its potentially high capacity. However, due to the restricted fundamental charging capacity of the electrode materials, the available energy of existing nanomaterial light emitting devices remains enough for a wide range of applications. In this research, ZnTe nanocrystals were synthesized using Nd: YAG laser at energy 600 mJ by 150 pulse number to form a battery device out of ITO/ZnTe/TPD/Ni. The spectra of the ZnTe NCs were assessed using ultraviolet-visible (UV-VIS) and More >

Abstract Petroleum-based cured epoxy polymers, used widely in aerospace, marine, and automotive industries, pose environmental threats due to their toxicity. Therefore, developing alternative curing systems for epoxy resin is crucial. This study explores the use of bio-based phenalkamines as curing agents for epoxy resin to enhance the mechanical properties of polymer composites and fiber-reinforced laminates. The functional groups, morphology, and thermal properties of the composites were analyzed using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). Mechanical properties of two epoxy systems—EP-TETA (triethylenetetramine-cured) and EP-PA (phenalkamine-cured)—were evaluated according to ASTM standards. More > Graphic Abstract
