Article Synopsis
- The study developed new biocomposites using tall oil fatty acid-modified lignin, citric acid-esterified polyvinyl alcohol, and unbleached fibers to improve thermal and mechanical properties while focusing on renewable resources.
- Characterization methods like FTIR, DMA, and TGA showed successful modification of materials and significant enhancements in viscoelastic properties and thermal stability, particularly with high levels of modified components.
- The best-performing biocomposite formulation demonstrated strong mechanical properties, with potential applications in sustainable packaging, automotive parts, building materials, and other industries needing eco-friendly solutions to replace traditional plastics.
In the present paper, nanofluid mixed convection is investigated in a square cavity with an adiabatic obstacle by using the Lattice Boltzmann method (LBM). This enclosure contains Fe-ethylene-glycol nanofluid and three constant temperature thermal sources at the left wall and bottom of the enclosure through a lateral wall. The fluid is incompressible, laminar, and Newtonian.

Various strategies have been proposed to address this issue, among which, prevascularization by coculturing of angiogenic and osteogenic cells on the scaffolds can alleviate this problem. In the present study, modified fibrous scaffolds were prepared by electrospinning and subsequent ultrasonication of polycaprolactone (PCL) containing nano-hydroxyapatite (n-HA), with/without nano-zinc oxide (n-ZnO), and polyethylene oxide [PEO] as a sacrificial agent.

The aim of this study was to evaluate the amount of increase in Hb levels after packed red blood cell (PRBC) transfusions in the Intensive Care Unit (ICU) patients and its related factors.
Materials And Methods: This cross-sectional study included 124 patients admitted to the ICU, and needed PRBC transfusion.
