This communication describes a new surface-enhanced Raman scattering (SERS) active silver substrate prepared by iodination of the evaporated silver foil. After iodination, the morphology of the silver substrate undergoes a self-evolution process in which it displays accordingly the UV-vis absorption

The erbium:yttrium aluminum garnet (Er:YAG) laser operates in the infrared spectrum at a wavelength of 2.94 microns. The absorption coefficient for water at this wavelength is approximately 10 times that of the carbon dioxide laser. It is anticipated that this
Food additives and contaminants, 22(12), 1219-1223 (2005-12-17)
The use of silver foils in various food preparations is a common practice in Middle Eastern and South East Asian countries. The FAO/WHO Joint Expert Committee on Food Additives (JECFA) has included silver in the list of food additives, but
Surface-enhanced Raman scattering (SERS) spectrometry of the diuretic drug triamterene is discussed. The SERS-active substrate used is a silver foil etched with nitric acid. The influence of solvent and sample doping method on sensivity, intercept and shape of the calibration
Rapid communications in mass spectrometry : RCM, 14(14), 1266-1268 (2000-08-05)
Nitrate-delta(15)N from groundwater samples is determined on an inorganic nitrate derivative using automated, continuous-flow elemental analyzer/isotope ratio mass spectrometry (EA/IRMS). Nitrate is extracted and concentrated based on a recently published ion-exchange resin method. Freeze-dried AgNO(3) (0.5-1.5 mg) is packed in
