Desiccation-tolerant plants are able to withstand dehydration and resume normal metabolic functions upon rehydration. These can be dehydrated until their cytoplasm enters a 'glassy state' in which molecular mobility is severely reduced. In desiccation-tolerant seeds, longevity enhanced by drying lowering storage temperature. these conditions, they still deteriorate slowly, but it not known if deteriorative processes include enzyme activity. The stability of photosynthetic organisms less...
β-Poly(vinylidene fluoride) (PVDF) is of large technological relevance due to its piezoelectric, pyroelectric and/ferroelectric properties. In this way, a variety methods have been developed obtain such electroactive β-phase, being the addition fillers one most popular, upscalable and innovative methods. The electrostatic interaction between negative charged with CH2 groups having positive charge density has widely accepted mechanism for direct formation polar β-phase on nanocomposites....
Residual porosity is observed in Inconel 718 samples manufactured by SLM within the optimum process window regardless parameters whose origin has been directly related to starting and finishing of laser scanning tracks. This concentrated preferentially overlaps fields (stripes chessboard strategies) borders. Location pores demonstrated on long stripes, where stops only at borders, not hatch. It concluded that due a high interaction time with powder which increases energy those points. Two...
Powder bed fusion–laser beam (PBF-LB) additive manufacturing enables the production of intricate, lightweight metal components aligned with Industry 4.0 and sustainable principles. However, residual stresses distortions challenge dimensional accuracy reliability parts. Inherent strain methods (ISMs) provide a computationally efficient approach to predicting these issues but often overlook transient thermal histories, limiting their accuracy. This paper introduces an enhanced inherent method...
Powder Bed Fusion–Laser Beam (PBF-LB) is a leading technique in metal additive manufacturing, yet it continues to face challenges related residual stresses and distortions. The inherent strain method has emerged as valuable predictive tool, offering early assessments of part behaviour due its simplicity manageable computational demands. However, accurately defining the tensor, which critical for these models, remains challenge. This study provides comprehensive analysis local meso-scale...
Conducting polymer composites are increasingly investigated for the development of piezoresistive materials sensor applications due to their outstanding electromechanical properties.
New Fe<sub>3</sub>O<sub>4</sub> nanostructures have been synthesized and added to a P(VDF-TrFE) matrix. The magnetostriction the magnetoelectric response obtained for 9 nm nanoparticle composites make these materials suitable technological applications such as sensors actuators.
A method to find the optimum process parameters for manufacturing nickel-based superalloy Inconel 738LC by laser powder bed fusion (LPBF) technology is presented. This material known form cracks during its processing LPBF technology; thus, have be optimized get a high quality product. In this work, objective of optimization was obtain samples with fewer pores and cracks. design experiments (DoE) technique implemented define reduced set samples. Each sample manufactured specific combination...
The objective of this research is to study the effect Zr on L-PBF processability, microstructure, and microhardness an AlZnMgCu-Zr alloy. Two AlZnMgCu-0.5 1.5 wt% pre-alloyed powders were produced by casting followed gas atomization. In addition, excess Mg Zn was added target compositions compensate for vaporization during L-PBF. as-atomized as-built heat treated specimens characterized via scanning electron microscopy, backscatter diffraction, transmission microscopy. Crack-free samples...
The aim of this work is to investigate the influence addition Cu on microstructure and microhardness a laser powder bed fusion (L-PBF)-fabricated AlSi10MgCu alloy. With goal, AlSi10Mg+4 wt%Cu pre-alloyed was produced by gas atomization. Following parameter optimization study, dense as-built specimens with high relative density 99.8% were fabricated. An outstanding value, exceeding 180 HV, obtained after aging at 160 °C for 16 h. This value similar that strength Al 7075 in T6 condition. aid...
Inconel 738LC (IN738LC) is a nickel-based superalloy specially used in the hot section components of turbine engines. One its main drawbacks relies on cracking susceptibility when it manufactured by laser powder bed fusion (LPBF). This paper analyzes influence minor alloying element concentration tendency IN738LC LPBF. For that objective, samples were using two powders, which presented different elements (Si, Zr and B). It was shown crack very depending for their manufacturing. In fact,...
Hexavalent chromium (CrVI) is a highly toxic metal and major environmental pollutant extensively used in more than 50 industries. The route of CrVI exposure for the general population oral intake. Chromium considered an important nutrient responsible carbohydrate metabolism. However, excess associated with various pathological conditions including reproductive dysfunction. can traverse placental barrier cause wide range abnormalities fetal development. Cr transported to offspring through...
Hexavalent chromium (CrVI) is a highly toxic metal and major environmental pollutant. Several studies indicate that CrVI exposure adversely affects reproductive function. We reported maternal Cr resulted in accumulation the organs of female offsprings. can cross placental barrier also be passed through breastfeeding. The present investigation aimed to determine persistent ( utero puberal period) exposure‐induced effects on functions mother offspring. Induction oxidative stress one plausible...
