The XRD and FTIR spectrum analysis of silver nanoparticles confirms the crystalline structure of silver nanoparticles and the reduction of silver ions to silver nanoparticles. The synthesized silver nanoparticle
Degradation of daguerreotype cover glasses Daguerreotypes are amongst the earliest photographic methods. The technique produces silver nanoparticles on a silvered copper plate. The image is very fragile, sen- sitive to pollutants, and readily damaged by abrasion; daguerreotypes were generally produced ...
Analyzing the results, we observed that in both media the most negative values are located on the O10 atoms of all the species while the less negative values for the anhydrous species are observed on the O1 atoms and for the dihydrated species on the O3 atom. Thus, these results for the...
We have studied the thermal denaturation of holo α-lactalbumin (α-LA) using FTIR spectroscopy by monitoring the absorbance of protein bands in the secondary structure sensitive amide I region. In agreement with results obtained by other techniques, a major cooperative melting transition is observed...
Promising results were obtained even if the enlargement of the bands had negative effects on the spectral resolution [19]. When a molecule is adsorbed on a metal surface in the form of nanoparticles or nanoislands, its infrared absorption is significantly more intense than expected [20]. This ...
Silver nanoparticles (AgNPs) have gained attention in medicine for their potent antibacterial, antiviral, and anti-inflammatory properties. The use of silver nanoparticles in ophthalmic solutions raises concerns regarding potential toxicity of nanoparticles to ocular tissues, such as the cornea, conjunctiva...
Silver nanoparticles interact with the urethane group and form a urethane-silver-urethane structure with a specific surface configuration and a higher resistance to temperature. Chemical transformations of the macromolecules on the surface of polyurethane film depend on both the silver nanoparticles ...
In This study, we used FTIR spectroscopy to evaluate the Changes in the functional groups of wheat flour resulting from treated seeds with Ag nanoparticles. FTIR Spectroscopy is a fast and reliable analytical method to identify functional compounds in wheat flour. The results of FTIR spectra ...
Optical band gap and particle size were calculated and is in agreement with the results obtained from TEM data. Transmission electron microscopy shows that the prepared silver and gold nanoparticles were mono dispersed within the polymeric matrix.A.M....
The different behavior of the material at 150 degrees C in respect to its activity at RT is mainly attributed to the additional formation of silver nanoparticles and to the possible formation and conversion of intermediates that are not formed and or converted at RT (thermodynamic limitation). ...
