BACKGROUND The use of nanotechnology has led to rapid growth in various areas. Thus, health and safety issues of nanoparticles (NPs) should be promptly addressed. Manganese oxide (MnO2) nanoparticles (NPs) are typically used for biomedical and industrial applications. However, characterizing the potential human health effects of MnO2 NPs is required before fully exploiting these materials. The ...

In this study, a series of zeolite-X-supported different crystal phases MnO2 (α-MnO2, β-MnO2, γ-MnO2, and σ-MnO2) catalysts were prepared via solid-state diffusion method high-heat treatment to explore their low-temperature NH3-SCR performance. All the featured typical octahedral zeolite X structures manganese dioxides species various types dispersed across support surface. Throughout entire te...

The novel zeolite AgX/CdO NPs composite catalyst has been fabricated under an ultrasound assisted dispersion route and identified by various analysis including FTIR, XRD, FESEM-EDAX, AFM, TEM, and EDAX-Dot mapping. Afterwards, for the first time, the zeolite AgX/CdO NPs composite has been exerted for the effective removal (adsorption and degradation) of fenitrothion (FN, O,O-dimethyl-O-(3-methy...

The affinity of zeolite nanoparticles (diameter of 8-12 nm) possessing high surface area and high pore volume towards human plasma proteins has been investigated. The protein composition (corona) of zeolite nanoparticles has been shown to be more dependent on the plasma protein concentrations and the type of zeolites than zeolite nanoparticles concentration. The number of proteins present in th...

Novel nanocomposites consisting of a water-soluble acrylamide-based photopolymer and colloidal zeolite nanoparticles of zeolite Beta and zeolite A were prepared. The interactions between the photopolymer components and zeolite nanoparticles in the photopolymerizable nanocomposites were characterized for the first time by (13)C nuclear magnetic resonance and visible spectroscopy. It was found th...

objective(s):   recently, applications of mno2 nanoparticles and microparticles in industry, pharmacology, and medicine have considerably expanded. mn distribution and clearance from brain and spinal cord tissue compared with muscle tissue of rats after single subcutaneous injection of nanoparticles and microparticle of mno2. pain sensory threshold of rat was evaluated as neurologic consequence...

Silver doped zeolite (AgX) has attracted significant attention as a good adsorbent of organic iodine (CH3I) in the gas phase. Heat treatment waste, which is composed iodine-sorbed AgX, may be necessary for disposal, would removed from AgX at high temperature. Therefore, sorption and desorption behaviors CH3I on X (13X) were investigated. Herein, labeled by 125I tracer was synthesized via isotop...
