[23] used rosin as a green chemical approach to fabricate ZnO nanoparticles, exhibiting a high photocatalytic activity for both methylene blue (100%) and methyl orange (82.78%) decomposition after 210 min under UV radiation. Moreover, the advantages in the

• , Vietnam 10.3762/bjnano.13.94 Abstract Zinc oxide nanoparticles (ZnO NPs) were successfully synthesized by a green method using rosin and zinc chloride as salt precursors. The phase structure, morphology, and particle size of ZnO were determined by X-ray powder diffraction, field emission scanning

The textile industry is one of the sources of organic pollution which is harmful to the environment and humans. Various

Rosin is also a plant-derived material containing different resin acids, especially abietic acid and pimaric acid with a general chemical formula of C20H30O2 (C19H29COOH) [28]. It is the inexpensive and eco-friendly solid byproduct obtained after

• (AA). Abietic acid is a resin acid, abundantly present in pinewood and other coniferous plants [16]. Rosin, the colorful resin material used as pigments in inks, varnishes and adhesives, largely consists of abietic acid. It is highly hydrophobic and soluble only in organic solvents such as acetone

Although cleaning may also extract natural lipids from the hair surface, the periodicity of the highest peaks is maintained constant throughout the four cases. The Fourier analyses, also included in the same figures, confirm that all exhibit a main

However, when comparing the intensity distribution of each sound wave along a single period, clear differences appear between the two samples. Only when they have rosin particles both look similar, but, after cleaning, although they

To ascertain if the roughness enhancement of the basic structure is the only feature responsible for the different stick–slip phenomenon control, the same structures were analyzed in the presence of rosin particles.
