TL;DR: The findings reveal that acute exposure of Yb 2 O 3 NPs through intranasal inhalation may cause toxicity via oxidative stress, which leads to a chronic inflammatory response.

TL;DR: In this paper, the conservation laws of a class of partial differential equations, which combines the nonlinear telegraph equations and nonlinear diffusion-convection equations, were investigated.

TL;DR: In this article, a complete approximate symmetry classification of a class of perturbed nonlinear wave equations is performed using the method originated from Fushchich and Shtelen, and large classes of approximate invariant solutions of the equations based on the Lie group method are constructed.

TL;DR: In this paper, a set of technological parameters for growing chrysanthemum-like ZnO particles on a large scale were optimized by orthogonal design theory, and the authors investigated the morphologies and crystalline structures of the as-synthesized three-dimensional ZnOs with a scanning electron microscope, x-ray diffractometer and transmission electron microscope.

TL;DR: In this paper, the chrysanthemum-like ZnO particles are prepared with zinc acetate dihydrate (Zn(CH3COO)22H2O) and sodium hydroxide (NaOH) used as main resources under the different concentrations of surfactant polyacrylamide (PAM), and the microstructure, morphology and the electromagnetic properties of the as-prepared products are characterized by high-resolution transmission electron microscopy (HRTEM), field emission environment scanning electron microscope (FEESEM) and microwave vector network
