Chemical oxidation processes are very advantageous owing to their effectiveness, ability to operate under various conditions of pH and temperature, and low operating costs, however, these processes form recalcitrant pollutants during the process of oxidation, leading to the generation of by-products, ...
Carbon nanotube towers up to 2 mm in height grew from the blocks, and the towers were easy to peel off the silicon substrate. The harvested towers were cast in epoxy and both ends were polished; one end for electrical connection, and the other end for use as an electrode. The nanotube ...
Mango waste, especially the peel, has been shown to have great promise as a potential source of food grade pectin with extraction yields of up to 21% [190] and promising values for the GA and DE. Traditionally, mineral acids have been employed in the extraction of pectins; however, this ...
Thus, on the one hand, manual harvesting is characterized by low productivity and high costs [5]; on the other hand, mechanical harvesting stands offer a low-cost option and increase production quality [6]. Therefore, with the aim to increase the harvesting efficiency within the traditional ...
The volatile oils hydrodistilled from the aerial parts and roots of O. carduchorum C.C Towns. (Fabaceae) have been chemically characterized for the first time. A total of 43 constituents with an abundance >0.03% were identified and quantified in the two
excess, while in fruits, essential oil (−)-α-pinene was shown to be the only enantiomer (e.e. = 100%). (+)-α-pinene and (−)-α-pinene in leaves essential oil and (+)-limonene and (−)-limonene in fruit essential oil were found in a racemic mixture (e.e. near 50%)...
In the process of high temperature aging, the coefficient of thermal expansion of substrate and coatings is not consistent, repeated thermal expansion and contraction process, the coatings will produce cracks and even peel off. In terms of materials, spinel materials have characteristic high ...
We will see that this technology, although still in development, is important as it has the potential to (i) reduce the carbon footprint of the electrical sector and (ii) enable faster electrification worldwide thanks to reduced installation costs....

Introduction Orange is one of the most popular citrus crops in the world. This fruit has several healthy compounds such as vitamin C, folic acid, antioxidants, flavonoi...
Some of the films prepared by some of the processes have issues from heat loss and/or loss of optical transmittance, in addition to production method issues that may prevent large- area processing and inexpensive fabrication costs [41]. Among these techniques, the CBD method for synthesizing ZnS...
