The CO sensing properties of a micro thermoelectric gas sensor (micro-TGS) with a double AuPtPd/SnO₂ and Pt/α-Al₂O₃ catalyst were investigated. While several nanometer sized Pt and Pd particles were uniformly dispersed on SnO₂, the Au particles were aggregated as particles measuring >10 nm in diameter. In situ diffuse reflectance Fourier transform Infrared spectroscopy (DRIFT) analysis of the c...
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...
PREPARATION OF FUNCTIONAL BIODEGRADABLE COMPOSITE POLYMERIC MICRO-/NANO-PARTICLES FOR BIOMEDICAL APPLICATIONS By
A new microfluidic approach to preparing anisotropic colloidal photonic crystal microparticles is developed and the self-assembly kinetics of colloidal nanoparticles is discussed. Based on the “coffee ring” effect in the self-assembly process of colloidal silica particle in strong solvent extraction environment, we successfully prepared anisotropic photonic crystal microparticles with different...
The set of composite materials that consist of micro/nanocellulose and complex K2Eu(MoO4)(PO4) luminescent oxide particles was prepared. The composites were studied by means of scanning electron microscopy, XRD analysis, dilatometry, differential scanning calorimetry and thermogravimetric analysis, and dielectric and luminescence spectroscopy.Dependencies of density, crystallinity, relative ext...
