Summary: Plasticized nanocomposites based on poly(lactic acid) were prepared using a two-step approach, adding two different oligomeric esters of lactic acid (OLAs) as plasticizers and fumed silica nanoparticles. The nanocomposites maintained remarkable elongation at break in the presence of the nanoparticles, with minimal effects on modulus and strength. However, thermo-mechanical properties deteriorated over time due to phase separation, and the nature of the plasticizer played a crucial role. Materials with hydroxyl-terminated OLAs showed higher stability upon aging, while acid-terminated plasticizer combined with silica nanoparticles accelerated the hydrolytic degradation of PLA, leading to brittleness and a significant decrease in molecular weight after 16 weeks of aging.

Summary: In this study, six nanocomposites based on different magnetic nanoparticles and a conducting polymer, poly(3-hexylthiophene-2,5-diyl) (P3HT), were synthesized. The nanoparticles were coated with either squalene and dodecanoic acid or P3HT, and the cores of the nanoparticles were made of nickel ferrite, cobalt ferrite, or magnetite. The average diameters of all synthesized nanoparticles were below 10 nm, with varying magnetic saturation at 300 K. The impact of different magnetic fillers on the conducting properties and the influence of the shell on the final electromagnetic properties of the nanocomposite were explored.

Summary: In this study, an (alpha-Al2O3 + ZrB2)/Al composite was prepared by promoting reactions among Al, ZrO2, and B2O3 powders. The nano-particles, with alpha-Al2O3 particles around 50 nm and ZrB2 particles around 10 nm in size, were mainly distributed along grain matrix boundaries, forming particle networks. The composite exhibited well-matched tensile strength and elongation, with the particle networks playing a positive role in piling up of dislocations during the tensile process.

Summary: Over the years, traditional metalworking fluids have had a negative impact on worker health and the environment. Minimum quantity lubricant (MQL) has successfully addressed this issue. Nanofluid-assisted MQL (NF-MQL) is a suggested technique to further enhance MQL performance, especially in machining hard-to-cut materials like stainless steel. This research aimed to improve the machining characteristics of AISI 316L stainless steel through dry, MQL, and multi-walled carbon nanotubes (MWCNT)-assisted MQL conditions, focusing on surface roughness, feed force, and cutting temperature.
