In this research, mesoporous material KIT-6 silica with high surface area (924.5 m2/g) and pore diameter (9.71 nm) was successfully synthesized using rice husk ash as a silica source. According to the SAXS analysis and TEM micrographs, the silicate structure of as-prepared KIT-was not distrupted by the functionalization and activation treatments with 3-APTES and glutaraldehyde, but showed a significant decrease in pore diameter and total pore volume as the compound was covalently bonded to the…

Chromium (Cr) is one of the most toxic chemical compounds due to the common use of chromium compounds in industry in addition to its natural sources (Costa et al., 2003). Exposure to chromium occurs via contaminants found in drinking water and food, through air containing particulates or mists of hexavalent chromium Cr (VI) compounds, or through skin contact with soil at hazardous waste sites (National Institute for Occupational Safety and Health, 2013). Cr (VI) may be found in drinking water…

1. Materials and suppliers • Caffeine (anhydrous), BASF, Germany, was generously donated by Dar Al Dawa Development and Investment Company. Caffeine is 1,3,7-trimethyl-3,7-dihydro-1H-purine-2,6-dione. It is white or almost white, crystalline powder or silky crystals. It is sparingly soluble in water, freely soluble in boiling water and slightly soluble in ethanol. It is used as central nervous system stimulant (British Pharmacopoeia 2009). • Methyl paraben was generously donated by Arab…

2.7. Hippocampal mitochondrial function 2.7.1. Hippocampal mitochondrial isolation After MWM test was finished, all animals were sacrificed and hippocampal tissues were removed. These tissues were minced and homogenized with glass handheld homogenizer. Mitochondria were obtained from the rat's hippocampus by differential centrifugation [38]. In the first centrifugation (at 1500 g, 10 min at 4°C), all of the broken cell debris and nuclei were sedimented. Then the supernatant was centrifuged…

1. Abstract In this study, reverse micellar extraction of asparaginase model system was carried out using CTAB/Iso-octane/hexanol/butanol system to optimize the forward and back extraction efficiency. By using Taguchi’s orthogonal array (OA), maximum forward extraction efficiency of 55.0%, 61.0% and 54% was achieved with an aqueous phase pH of 11.0, 150mM CTAB/Iso-octane and 0.1 M NaCl, respectively. Similarly, Taguchi’s orthogonal array (OA) was applied to optimize the pH of stripping phase,…

2.1 Background of pineapple 2.1.1 Pineapple Pineapple is a tropical which is planted in many tropical countries such as Sri Lanka, Taiwan and Africa. It is known as ananas commonly where it’s scientific name is ananas comoscus and also one of the most important commercial fruitcrops in the world,known as the queen of fruits. Because it has excellent flavour and taste. Pineapple is the third mostimportant tropical fruit in the world after Banana and Citrus. They are consumed or served fresh,…

In 2003, li Also as much coworkers70 synthesized 3-arylimidazo[1,2-a]pyrimidines from imidazo[1,2-a]pyrimidine a unsubstituted heterocycle In those 3-position Toward performing regulate arylation response with aryl bromides. Those creator utilized Pd(OAc)2 (2 mol %) Concerning illustration An catalyst, PPh3 (4 mol %) Likewise An ligand, Also Cs2CO3 (2 equiv) Concerning illustration An base, those response advanced proficiently in 1,4-dioxane during 100 °C. Those yield might have been attained in…

3.11.2. Effects of pH The pH is a very important parameter which controls the extent of photoassisted degradation. The effects of pH on degradation of CR were investigated using 15.0 mg of LDH; 1x10-5 M CR solution in the pH range of 4.0 to 11.0, adjusted by addition of either 0.1 M HCl or NaOH. The plot of C/C0 vs. irradiation time of aqueous CR is presented in Fig.12(B). The efficiency of photodegradation of aqueous CR was found to be higher in the acidic medium particularly at pH 4 (~99.7%)…

1.2.2. Influence on nutritional attributes Apple and pear cultivars are well known for being good sources of antioxidant properties, especially for their content of polyphenolic compounds concentrated in their skin. Apples contain natural sugars, organic acids, dietary fiber, minerals and vitamins, whereas pears are good sources of fiber and micronutrients such as chlorogenic acid, flavonols and arbutin (Sinha 2012). In general, pear juice is characterized by similar soluble solids content than…
