Nanotechnology has an extensive series of applications in agronomy and important role the future sustainable agriculture. The agricultural industries should be supported by innovative active materials such as nanofertilizers, nanofungicides, nanopesticides. It is necessary current situation to meet dietary needs constantly expanding world population. Nearly one-third crops grown conventionally suffer damage, mostly a result pest infestation, microbiological assaults, natural disasters, poor...

Abstract Sandwich structures have gained considerable attention in engineering due to their lightweight nature and excellent mechanical properties. However, impact resistance has been a critical limitation. This research addresses this challenge by enhancing the of sandwich through integration fused deposition modeling (FDM) with glass fiber‐reinforced polylactic acid (PLA + GF) composites. Three core geometries trihexagonal, hexagonal, triangular are 3D printed using FDM technology, while...

Abstract In recent years, there has been a lot of interest in the use natural fibers as reinforcements and ceramic particles fillers polymer composites. However, unoptimized process parameters frequently result flaws such cavity development, non‐homogeneous distribution, poor wettability, particle agglomeration. By optimizing filler %, stirring duration, number fiber layers, this study seeks to improve homogeneous distribution matrix reinforcement. This was accomplished by employing L 27...

Abstract The use of natural fibers as reinforcements in polymer composites has seen significant growth over recent decades. Despite their potential, these face limitations high‐temperature environments. To address this, ceramic particles like silicon carbide (SiC) can be introduced to enhance thermal stability and durability. This study investigates the impact SiC on mechanical characteristics woven bamboo fiber hybrid composites. By incorporating various weight fractions into an epoxy...

This study introduces a novel approach for predicting the mechanical properties of 3D-printed polylactic acid wood composites using gene expression programming (GEP) and artificial neural networks (ANN) modeling methods. Addressing challenge determining optimal process parameters in fused deposition natural fiber composites, experiments were designed Taguchi’s L27 orthogonal array. Five key analyzed: layer thickness (100–300 μm), printing speed (40–90 mm/s), raster angle (0°–90°), infill...

Spent vanadium catalysts of sulfuric acid production (main elemental composition in wt%: 7.5 V, 9.1 K, 10.2 S, 23.2 Si and 1.4 Fe) can be used as a secondary source vanadium. Extraction was studied using two-step leaching (acidic reductive) spent with further oxidizing solutions. The factors hydrolysis temperature, concentration (H2SO4, Na2SO3) ((NH4)2S2O8) reagents, solid/liquid ratio, mixing parameters, time thermohydrolysis were systematically investigated. solubility V2O5 investigated...

For additional strength increase, 5, 10, and 15% TiC was added to the quinary CoCrFeMnNi high entropy alloy (HEA) at laser powers of 100, 400, 700 watts while selective melting method engaged in fabrication. Microstructure, porosity, density, yield tensile strengths, elongation, microhardness are among parameters analyzed. As appreciated from 5 15%, microstructure revealed that particles were dispersed within matrix. Also, addition ensued grain size refinement with increasing particle...
