Hierarchical m‐ZrO₂ Nanorods Template‐Free Synthesis by Hydrothermal Method

Abstract

Hierarchical m‐ZrO2 nanorods synthesized by the simple hydrothermal method, and the possible formation mechanism was proposed based on a series of chemical reactions. The as‐synthesized products are composed of many 1D ZrO2·nH2O nanorods with 150–250 nm in diameter and 6–8 μm in length. The final product after annealing at the 700°C was involved into hierarchical monoclinic m‐ZrO2 nanorods, and the big nanorod was made up of many small nanorods with 10–20 nm in diameter and 400–500 nm in length. This discovery could helpful in understanding, the chemical properties of ZrB2 and ZrO2, the design of its derivatives for m‐ZrO2 nanomaterials.

Inhibition of LPS-induced inflammatory mediators by 3-hydroxyanthranilic acid in macrophages through suppression of PI3K/NF-κB signaling pathways

“…3 Many bacterial components and products including lipopolysaccharide (LPS) can initiate local inflammatory responses which are mainly mediated by macrophages and mast cells. 4,5 Activated macrophages are important in inflammatory processes and have crucial functions that include antigen presentation, phagocytosis and immunomodulation through the production of various inflammatory mediators. Additionally, persistent pro-inflammatory macrophages contribute to the development of chronic inflammatory diseases such as atherosclerosis, type 2 diabetes and hay fever.…”
