USING SYNTHETIC ACID COMPOSITIONS AS ALTERNATIVES TO CONVENTIONAL ACIDS TN THE OIL AND GAS INDUSTRYA synthetic acid composition for use in oil industry activities, said composition comprising: urea and hydrogen chloride in a molar ratio of not less than 0.1:1; a metal iodide or iodate; an ...
As well-known aramid fiber-reinforced polymer (AFRP) is a highly effective synthetic fiber in textiles and composites. This type of fiber has many advantages, such as great strength, high elasticity, and heat resistance, with a density 40% lower than GFRP but at a somewhat higher cost [63]...
The rising pollution by synthetic dyes from the textile industry is a serious health problem calling for safer chemicals and textile production methods. As an alternative, bio-based colorants are increasingly used for food, cosmetics, flavors, medical applications. Here we review bio-based textile dy...
The environmental and financial issues posed by produced water, a byproduct of the oil and gas industry, are enormous1,2,3,4. It contains dissolved and suspended impurities such as oil, gas, minerals, and microorganisms and its volume can be up to 10 times greater than that of oil and g...
Liquid-solid transition, also known as gelation, is a specific form of phase separation in which molecules cross-link to form a highly interconnected compartment with solid – like dynamical properties. Here, we utilize RNA hairpin coat-protein binding s
Fig. 1. a) Regional location map of the Gulf of Suez; b) Oil field locations in the Gulf of Suez with the Hilal field highlighted (modified after Radwan et al., 2020b). 2. Wellbore damage or breakout Commonly, drilled wellbores experience hole enlargement in some zones which have a te...
Synthetic bio-oil aqueous fraction steam reforming was performed using Co/SBA-15 catalysts. Fig. 1 displays the catalytic behavior with time-on-stream. As observed, at low TOS conversion decay is more pronounced and it is smoothed until almost no loss of conversion is observed between 20 and ...
As mentioned previously, the discovery that the water level in a molecular sieve-based alkylation or transalkylation catalyst beneficially affects the life of the catalyst is quite surprising in light of the conventional practice of driving off substantially all of the water during calcination. Although...
Droplet-based microfluidics, which uses picoliter to nanoliter-sized droplets as reaction vessels to perform cellular screens, provides a promising approach to achieve this goal. Due to the miniaturization over several orders of magnitude as compared to conventional plate-based screens, the number of ...
while the minimal or no toxicity effect was observed in BHK cells after treatment with both the plant extracts (ANE: IC50 = 215 µg/mL and ANH: IC50 = 183 µg/mL). Moreover, the conventional chemotherapeutic drug (cisplatin) showed more cytotoxicity with the IC50value of 25.83...
