By definition, the valorization process is the process in which a product gains value through the effort and skill of the laborer during production. What is the meaning of valorization? By definition, the meaning of valorization is the value or worth of a product, and the value or skill of...
Accordingly, this study laid great emphasis on elucidating the mechanistic role of CO2 in pyrolysis of orange peel. The thermo-gravimetric analysis (TGA) confirmed that no occurrence of the heterogeneous reactions between the solid sample and CO2. However, the gaseous effluents from pyrolysis of ...
Fitting the isotherm models revealed that the Langmuir model could better predict the experimental adsorption data, meaning monolayer adsorption occurred. The maximum dye adsorption capacity of the porous nanosilica obtained from the Langmuir model constant was 256.41mg/g. Also, the pseudo-second-order ...
The word Carambola is derived from the Sanskrit word karmaranga meaning "food appetizer". It is a good source of potassium, copper, as well as folate and pantothenic acid. The Ascorbic acid level of the star fruit is believed to be responsible for its sweet or sour taste. For a sweet ...
These by-products contain high amounts of moisture (approximately 90%), along with organic components (Doulabi et al., 2020), meaning that they putrefy easily. Thus, if discarded inappropriately, EB could pose serious threats to the environment, such as greenhouse gas emission, unpleasant odor ...
Such fuel provides about 12–22 MJ/kg of energy, meaning impressive combustibility. In this case, banana peels act not only as a combustible polysaccharide source but also as a binder for the whole briquette, making it easy to mold [86]. Another way of providing energy is the use of ...
The catalytic hydrogenolysis of glycerol on a commercial scale depends on the purity of glycerol, meaning that various impurities derived from biodiesel production affect the reaction. Water, alkali hydroxides and free fatty acids can also impact the performance of the process, including catalyst ...
quantification and application in the context of dyeing. To ensure an exhaustive review, literature materials, such as text books, articles, abstracts and peer-reviewed publications listed in Web-of Science and Google scholar, were searched using the phrases “quinone dyes”, “natural quinone”, ...
Organic carboxylation and reduction of CO2 are endergonic reactions with a high kinetic barrier, meaning they require high amount of energy [49]. Despite the many advantages of CO2 utilization, CCU remains a nascent technology with many obstacles to be overcome. From the perspective of biology, ...
As expected, the pro-oxidant agent highly reduced the GSH/GSSG ratio by about 4-fold, meaning that GSH was depleted in favor of GSSG generation (Figure 9). Figure 9. Effect of S10, S20, and S50 fractions from Sideritis sipylea Boiss on the GSH/GSSG ratio after treatment with the pro-...
