This article gives some proposals on how to grow silver nanoparticles using different methods. Dilute silver salts are recommended as the metal precursor starting solutions. The formation of the silver nanoparticles is to be monitored using UV-Vis absorpt... see more

A theoretical study on the thymoquinone compound has been performed through two theoretical methods, DFT/B3LYP and HF with 6-31G, 6-31G(d, p) and 6-31++G(d, p) basis sets using Gaussian 09 program. Some theoretical properties, like vibrational and electro... see more

The latest studies outlined the important role of polyphenols from grapes and wines, especially from red variety. The polyphenols are those antioxidants compound who favouring the biochemical reactions which protect the cardiovascular system and also have... see more

Chlorophyll a is the most abundant pigment on Earth responsible for trapping light energy to perform photosynthesis in green plants. This molecule has been studied for many years from different points of interest with both experimental and theoretical met... see more

The colour of olive oil is due to the presence of natural pigments belonging to the class of carotenoids, chlorophylls, and their derivatives. These substances, other than being responsible for the colour, an important qualitative feature of the oil, have... see more

The absorbing and scattering nature of aerosols affects the total radiative forcing and is quantified by single scattering albedo (SSA), which is defined as the absorption to total extinction ratio. There are limited measurements of SSA in the ultraviolet... see more

A series of natural photoactive dyes, named as D1–D6 were successfully extracted from six kinds of plant leaves for solar cells. The photoelectrical properties of dyes were measured via UV-Vis absorption spectra, cyclic voltammetry as well as photov... see more
