A comparative study of anti-resonance effects in InSe and InSe doped with GaS, using the resonant Raman spectroscopy is presented. The nonpolar optical phonon of  symmetry in InSe exhibits a pronounced decrease in the Raman cross-section at excitation energy 2.585 eV. In InSe doped with GaS samples, it is found that the anti-resonance behavior decreases as doping contents are increased. To acco...

A study combining vibrational spectroscopy and first-principles theory is presented for a hydrogen-related defect in natural anatase TiO2 that characterized by an O–H mode at 3373 cm−1 (10 K). Based on complementary Raman scattering, IR absorption, electron paramagnetic resonance, secondary ion mass spectrometry data supported also ab initio calculations, it tentatively proposed the responsible...

in this research, tellurium (te) film with thicknesses of 100-250 nm were deposited on ceramic substrates by thermal evaporation at 373 k. the thickness of the film was determined by rutherford backscattering spectroscopy. the influence of the thickness on the structural, morphological and molecular bonds was characterized using xrd, scanning electron microscope, and raman spectroscopy. the xrd...

Application of nanoparticles (NPs) in environmental remediation such as water purification requires a detailed understanding of the mechanistic aspects of the interaction between the species involved. Here, an attempt was made to understand the chemistry of noble metal nanoparticle-pesticide interaction, as these nanosystems are being used extensively for water purification. Our model pesticide...

Examination of egg white proteins and effects of high pressure on select physical and functional properties" (2010). Egg white proteins have become an important and desirable ingredient to the food industry due to their functional properties which include gelling, foaming, and emulsification. Egg white is also well recognized as an excellent source of nutrition. The goal of this work was to det...

ft-raman spectra of saffron (crocus sativus l.) with a partial assignment is reported. based on the raman data, it is concluded that main pigments in saffron are crocins and crocetin. it is proposed that the quickly attainable ft-raman spectrum of solid saffron, may be used as a means of saffron standardization.

Crystals of the barium molybdates BaKYb(MoO4)3 and BaMoO4 were obtained by spontaneous nucleation from high-temperature flux experiments. The compounds characterized energy-dispersive spectrometry (EDS) Raman spectroscopy, their structure was solved single-crystal X-ray diffraction data at room temperature. crystallizes in tetragonal I41/a symmetry with a ?= ?b ?5.5723(4) c ?12.7954(9) Å.
