Recovery of Cerium Oxide Abrasive from an Abrasive–Glass Polishing Waste through Alkaline Roasting Followed by Water Leaching

Metals, 2020
Abrasive–glass polishing waste is generated from the polishing process of glass components by using cerium oxide abrasive, which contains the cerium oxide abrasive and the polished glass. This study attempted to recover the cerium oxide abrasive from the

How to Chemically Protect PFAS‐Free Membranes in Fuel Cells: Radical Quenching Poly(vinylphosphonic acid) Layer

Advanced Functional Materials, EarlyView.
Hydrocarbon membranes are a greener alternative to PFSA in PEM fuel cells, but degrade rapidly from radical attack. We present a novel strategy using poly(vinylphosphonic acid) (PVPA) as a local radical scavenger. Incorporated as an interfacial barrier, PVPA enhances chemical stability and significantly extends membrane lifetime under accelerated ...

Recent advances in the synthesis and biological applications of cerium oxide nanoparticles

上海师范大学学报. 自然科学版, 2019
Cerium oxide(CeO2-x,x=0~0.5) nanoparticles are attractive as a kind of widely used rare earth oxides due to their excellent catalytic activities,which are originated from the reversible conversion between Ce3+ and Ce4+ as well as the existence of oxygen ...

Selective Laser Sintering of Polymer Nanocomposites [PDF]

, 2007
This paper describes the fabrication and characterization of polymer nanocomposite (PNC) materials for use in the selective laser sintering (SLS) process. PNC materials are of great interest generally because of their excellent physical properties, and

Sintering of Cerium Oxide

Journal of the Ceramic Association, Japan, 1966
Sintering of cerium oxide with or without additives in various atmospheres has been studied. As starting materials, cerous nitrate (99% purity) and cerous oxalate were used.The conclusions were the followings:1) The cerium oxide powder obtained at the lower calcining temperature between 400°C and 800°C was better sintered than the one obtained at the ...

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

Advanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Environmental Geochemistry of Cerium: Applications and Toxicology of Cerium Oxide Nanoparticles [PDF]

International Journal of Environmental Research and Public Health, 2015
Cerium is the most abundant of rare-earth metals found in the Earth’s crust. Several Ce-carbonate, -phosphate, -silicate, and -(hydr)oxide minerals have been historically mined and processed for pharmaceutical uses and industrial applications. Of all Ce minerals, cerium dioxide has received much attention in the global nanotechnology market due to ...

Molecular Templating Enables Precise CeNiC2/Ni Heterostructures for Efficient Alkaline Hydrogen Oxidation

Advanced Functional Materials, EarlyView.
A series of Bi‐TMCs‐based heterostructures (CeNiC2/Ni‐x%) have been precisely constructed through a “molecular‐template”‐assisted strategy, which exhibits remarkable alkaline HOR performance derived from the strong synergy between Ni and CeNiC2 components.
