The present work demonstrates a simple and low-cost method to produce bulk quantities of graphene material through the thermal treatment graphite oxide (GO).
Activated carbon modified by ozone treatment was examined. The process carried out in a glass reactor under continuous flow of through bed activated for 15, 30, 60, 120, and 240 min. unmodified materials were characterized Raman spectroscopy observed scanning electron microscopy (SEM). Thermogravimetric analysis used to estimate the presence oxygen groups structure. surface area pore size distribution examined nitrogen adsorption method at 77 K. Moreover, Fourier transform infrared (FTIR)...
Biomechanical properties of bone depend on the composition and organization collagen fibers. In this study, Raman microspectroscopy was employed to determine content mineral organic constituents orientation fibers in spongy human head femur at microstructural level. Changes structure trabecula were illustrated using spectral mapping. The polarized spectra permit separate analysis local variations composition. ratios ν2PO4 3−/Amide III, ν4PO4 III ν1CO3 2−/ν2PO4 3− are used describe relative...
Raman microspectroscopy was used to examine the biochemical composition and molecular structure of extracellular matrix in spongy subchondral bone collected from patients with clinical radiological evidence idiopathic osteoarthritis hip who underwent a femoral neck fracture, as result trauma, without previous osteoarthritis. The objectives study were determine levels mineralization, carbonate accumulation collagen quality tissue. comparison control subject is less mineralized due decrease...
Abstract Bioengineered spider silks are a biomaterial with great potential for applications in biomedicine. They biocompatible,biodegradable and can self-assemble into films, hydrogels, scaffolds, fibers, capsules spheres. A novel, tag-free, bioengineered silk named MS2(9x) was constructed. It is 9-mer of the consensus motif derived from MaSp2–the spidroin Nephila clavipes dragline silk. Thermal acidic extraction methods were used to purify MS2(9x). Both purification protocols gave similar...
The aim of this study was to investigate the effectiveness Raman spectroscopy in determination changes composition and structure human tooth enamel with caries by use new parameters such as band position, full width at half maximum line shape band. values spectroscopic were obtained analysis scattering spectra. We proposed base diagnosis on several determined simultaneous scattering, Rayleigh fluorescence emission. verified correlations between few selected severity dental caries. spectral...
An antifungal active fraction (AAF) from the coelomic fluid (CF) of earthworm Dendrobaena veneta was isolated. The aim study to analyze activity AAF and carry out chemical characterization fraction. showed against a clinical C. albicans isolate, ATCC 10231, krusei 6258. It effectively reduced metabolic cells influenced their morphology after 48 hours incubation. Scanning electron microscopy (SEM) images revealed loss integrity cell wall induced by Calcofluor White staining changes in...
Current diagnostic methods for enamel caries detection are unable to detect lesions at a very early stage. Previous studies indicated that Raman spectroscopy is promising and effective tool the of caries. In our previous work, we showed several independent parameters obtained during analysis spectra allow identification carious formed in oral cavity (natural caries). The aim this research was estimate effectiveness determination specific changes human affected by artificial values study were...
Abstract Hydroxyapatite modified with methacrylate groups-bearing polyhedral oligomeric silsesquioxane was for the first time applied as a filler in experimental composite dental applications. As modifier changed hydroxyapatite surface from hydrophilic to hydrophobic, it predicted that stability of obtained composites would be improved comparison raw hydroxyapatite-filled composites. The oral imitating environment, basic physicochemical properties, and remineralizing potential understood...
ABSTRACT Although phenol‐formaldehyde (PF) resins possess excellent properties, they emit toxic substances during the decomposition of crosslinking agent. Therefore, studies are being carried out on fillers, which can reduce amount In this article, synthesis diazonium‐modified carbon black was conducted. Diazonium modification allows effective incorporation hydroxymethyl groups, responsible for PF resins. Modified materials were used as active fillers in composites and abrasive tools. Due to...
Silica aerogel-based materials exhibit a great potential for application in many industrial applications due to their unique porous structure. In the framework of this study, carbon fiber and nickel coated fiber-silica aerogel nanocomposites were proposed as effective electromagnetic shielding material. Herein, initial oxidation surface fibers allowed deposition durable Ni metallic nanolayer. The prepared way then introduced into silica structure, which resulted obtaining two that differed...
Abstract The most popular drugs used to prevent osteoporosis that causes low mineral density and weakened microstructure of bones are bisphosphonates. Bisphosphonates can be administered in several ways, but each delivery method has drawbacks. Due this, new methods their being sought. Titanium implants coated with calcium titanate were prepared this work as carriers for Such a modification been proposed order improve the therapeutic properties implant. Slow release drug at constant level...
The goal of this work was to evaluate the ability Raman spectroscopy identify molecular organization and chemical composition extracellular matrix such as collagen fibers arrangement, level mineralization, carbonate accumulation in mineral phase spongy bone human head femur. Changes structure tissue were illustrated using maps polarized spectra. In particular, purpose present study determination arrangement mineralized on surface trabecula by transformations spectra maps. Transformations...
ABSTRACT The dependence of the depth cure (DOC) and degree conversion (DC) on experimental commercial materials were determined according to ISO 4049 procedure with use Raman spectroscopy, respectively. Moreover, an attempt was made find correlation between DOC DC material. hypothesis that curing time recommended by manufacturers is appropriate for both achieve comparable values examined properties. impact filler characteristic clearly observed. longer provides a deeper (DOC values) higher...
ABSTRACT The epithelium of the ventral surface apex tongue in most birds is specified by presence special superficial layer called lingual nail. aim present study to determine localization alpha‐keratin and beta‐keratin (corneous beta protein) this domestic goose using immunohistochemistry staining Raman spectroscopy analysis. Due lack commercially available antibodies detect protein), was used as a specific tool describe secondary structure proteins. immunohistochemical (IHC) detections...
A powder metallurgy process was used to produce high temperature self-lubricating composites based on Ni, with varying content of calcium fluoride (10 wt.% and 20 wt.%). The wear properties the samples were investigated by a pin-on-disc test at elevated temperature, up 600 °C. Aside from standard techniques for sample characterization, confocal microscopy micro-Raman spectroscopy first time this type sample. These methods examine changes in topography detect distribution tribofilm surfaces....
