To ensure an adequate clinical composite filling light source for photopolymerization is of great importance. In everyday conditions commonly used unit polymerization material halogen curing unit. The development new blue superbright emitting diodes (LED) 470 nm wavelengths comes as alternative to standard 450-470 wavelengths. purpose this study was compare the degree conversion (DC) and temperature rise four hybrid materials: Tetric Ceram, Pertac II, Valux Plus Degufill Mineral during 40 s...
This study analyzed the degree of conversion, temperature increase and polymerization shrinkage two hybrid composite materials polymerized with a halogen lamp using three illumination modes photopolymerization device based on blue light emitting diodes. The conversion Tetric Ceram (TC) (Ivoclar Vivadent) Filtek Z 250 (F) (3M/ESPE) was measured by Fourier transformation infrared spectroscopy at surface 2-mm depth; rise digital multimeter, linear during cure laser interferometry. Composite...
The objective of this study was to evaluate the degree conversion and temperature rise in three different composite materials when illuminated by an experimental light source [blue superbright emitting diodes (LEDs)] compared with plasma traditional photopolymerization unit. were measured using Fourier transform infrared (FTIR) spectroscopy digital multimeter, respectively. results revealed significantly higher values case conventional curing than other two sources whereas lower blue LEDs...
An optimal degree of conversion and minimal polymerization shrinkage are generally antagonistic goals, as increased monomer invariably leads to elevated values. However, both parameters indispensable for an resin composite restoration. A number approaches have been used reduce the stress on restoration cavity wall interface, such dentine bonding agents counteract shrinkage, stress‐absorbing lining materials low‐intensity curing lights control flow capacity material during polymerization....
Abstract Low wavenumber Raman scattering of the acoustic vibrational modes nanoparticles was used for determination size distribution free dielectric and semiconductor embedded in matrices. The theoretical background as well experimental results noninteracting strong interaction with a surrounding matrix is described. approach based on 1/ν dependence light‐to‐vibration coupling coefficient fact that each nanocrystallite diameter D vibrates its eigenfrequency ν ∼ 1/ . model calculation...
Transition-metal-oxide/transition-metal nanocomposites, such as NiO/Ni, FeO/Fe, and CoO/Co, have been the subject of much recent investigation (i) because their potential applications (ii) they are good model systems for studies some effects on nanoscale. They used, example, catalysts, fuel-cell electrodes, magnetic memories, etc. When a nanocomposite is composed both ferromagnetic (FM) antiferromagnetic (AFM) nanoparticles, interesting physical properties can occur, phenomenon exchange bias...
Microporous and macro-mesoporous silicon templates for surface-enhanced Raman scattering (SERS) substrates were produced by anodization of low doped p-type wafers. By immersion plating in AgNO3, the covered with silver metallic film consisting different nanostructures. Scanning electron microscopy (SEM) micrographs these SERS showed diverse morphology significant difference an average size distribution nanoparticles. Ultraviolet-visible-near-infrared (UV-Vis-NIR) reflection spectroscopy...
Soils of the urban and suburban area Belgrade have been hardly studied, especially concerning their concentrations potentially toxic metals. The present paper is aimed at determining possible pollution in soils. total acid soluble heavy metals As samples were determined. It was found that they arranged order Zn > Ni Pb Cr Cu Hg Cd collected examined (the elements based on arithmetic mean concentrations). In all 0–10 40–50 cm depths from 46 selected sites, contents lower depth 40-50 cm. Using...
