This study aimed to develop a food-grade holo-cellulose rapeseed cake fibrous particles stabilizer using hush pre-treatment (sequential alkali-acid, and heat), followed by ultrasonic cavitation (USC) or high-pressure microjet (HPM) processing. The pretreatment improved particle suspension stability (...
View PDF Article preview Abstract Abstract In the present study, the soy protein and whey protein isolates were hydrolysed using food-grade endoenzymes (papain and pancreatin) for different time periods (10, 30, 60, 90, and 120 min) at 35 °C. Several functional properties were examined at ...
The LC-MS grade acetonitrile (ACN), water, and formic acid (FA) used for electrospray solvent were all purchased from Fisher Scientific (Nazareth, PA, USA), as well as plain microscope glass slides (1 mm). Nitrogen gas used to dry samples was purchased from Arc Gases (Raleigh, NC, USA...
The use of Analytical Research-grade (AR) chemicals (Merck and Sigma-Aldrich, Germany) were ensured all through this study with no further purification or modification to them as the chemicals are in their pure form (99.9%). The chemicals used are primarily nitric acid and hydrochloric acid. ...
Kama Illias. Chemistry to Music: Discovering how Music-Based Teaching Affects Academic Achievement and Student Motivation in an 8th Grade Science Class in Debremarkos Elementary school. Teachers should have access to new and innovative tools in order to
SABIC's extensive portfolio of light-weighting materials was also extended this year with the introduction of a new grade of ULTEM™ foam. Lighter than ever, and fully compatible with thermosets and metal laminates, the new formulation provides a core for 'sandwich' construction, lending itself ...
For 1H-NMR, 200 mg of finely ground coffee powder was extracted at room temperature in 1 mL HPLC grade methanol. After two-minute agitation with vortex, the samples were centrifuged for 10 min at 17°C and 450 μL of the extract was transferred to the NMR tube. Last, 90 ...
[22]. The levels of Cu from this study are higher than those reported previously in some khat-growing regions from Ethiopia, whose levels were 5.11–9.55 mg/kg [12], but also lower than those obtained from khat-growing regions such as Aweday in Ethiopia with concentrations of 0.10–...
Experiments showed that refractory grade bauxite had high fluoride removal efficiency in comparison to other three adsorbents. With pH up to 5.5, the percentage of fluoride adsorption onto refractory grade bauxite was found to increase but decreased with increase in pH. The adsorption process was ...
However, in Iran, GC is already a compulsory subject in Grade 9 of Iran’s innovative science curriculum that is designed to generate informed and scientifically literate citizens who both appreciate and understand that natural resources are finite, and that the environment should be free of waste...
