Hydroxylamine reduced silver colloid for naphthalene and phenanthrene detection using surface-enhanced Raman spectroscopy

Nut-like MOF/hydroxylated graphene hybrid materials for adsorptive desulfurization of thiophene

“…The Raman spectrum of parent Cu-BTC was in agreement with the literature reported before. 38,47,48 The peaks observed at 1360 cm À1 (D band) and 1585 cm À1 (G band) correspond to the characteristic signals of sp 3 and sp 2 hybridization of C atoms, respectively. It can be seen that the intensities of the D band and the G band were distinctly enhanced with increasing HG content.…”

Charge transfer-induced enhancement of a Raman signal in a hybrid Ag–GaN nanostructure

“…The underlying mechanism of the nanoparticle interactions with the analytes has been discussed based on experimental results using density functional theory (DFT) calculations. [12][13][14][15][16][17][18] Several other materials, such as silicon, graphene, and actinide-embedded structures, have been used as supporting substrates for distributing Ag and Au nanoparticles to enhance the interactions between the nanoparticles and analyte molecules and consequently improve the limits of detection and enhancement factors. [19][20][21] Similarly, the GaN thin lms of various morphologies (planar and porous) have been used as supports for depositing silver nanoparticles, on which a signicant enhancement in the Raman signal has been reported.…”

Comparative adsorption of crude oil using mango (Mangnifera indica) shell and mango shell activated carbon

“…Effective usage of these waste materials enhances their reuse and savings in disposal fee. As a supportive means of enhancing the quality of this present work, previous contributions in the field of adsorption and waste water treatments were acknowledged [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23].…”
