Determination of urea in milk is inevitable in the dairy industry for the quality control processes. A simple and cost-effective method was developed to determine the concentration of urea in milk by silver nan
There is a problem facing the use of a UV-visible spectrum for the calculation of the concentration of different species if two species absorb at the same region, and in this case there is a need to change the reagents to obtain different colours for different species. Also, it is importan...

The transmittance spectrum of the polyimide film was measured with a v-730 spectrophotometer (JASCO Corporation, Tokyo, Japan). A liquid film of 4-MAAB was formed by melting the (5) Structure-Based Optimization of 1,2,4-Triazole-3-Thione Derivatives: Improving Inhibition of NDM-/VIM-Type ...
Ultraviolet (UV) radiation is highly energetic electromagnetic radiation from light waves below that of the visible light spectrum. The wavelengths for UV radiation range from 100-400 nm, including UV-A (315-400 nm), UV-B (280-315 nm), and UV-C (100-280 nm) [1]. While the earth's...

films. It may be possible to detect a shift in the peak response at 400 nm, which is connected to a shift in the energy gap for a certain Ag concentration in the direction of the visible spectrum. The second peak was discovered at 790 and related to an increase in the active layer's...

size, shape, state of agglomeration, concentration,refractive index, etc [58]. Nanostructure sols of metals such as gold, silver, and copper show characteristic UV-Vis extinction spectra due to the existence of an LSPR signal in the visible part of the spectrum [59]. Goldnanoparticleswere evalu...
In general, wavelengths more than 700 nm are considered as IR range. The visible spectrum covers wavelengths from 400 to 700 nm. The wavelengths 200 to 400 nm are depicted as the UV spectrum. Both UV and IR rays are invisible to humans due to a lack of receptors. Ray directions are a...
