Compiled by Alex Pena ~ ‘Catalyst’: “to spark, to ignite, energize, mobilize; something that accelerates a reaction (DDI)." Thought-provoking & motivational quotes and stories for you to read, reflect on and move forward in making creative and
These processes are carried out by facilitating a reaction between any feedstock-derived oil and alcohol in the presence of a suitable catalyst (Maddikeri et al. 2012). Triglycerides are produced when three fatty acids combine with glycerol and are chiefly found in humans and animals as body ...
These reagents may be used in the presence of UV light, catalyst, ultrasound to advance the oxidation process. AOPs may be classified broadly into four groups: photocatalytic process (H2O2/UV, O3/H2O2/UV, UV/TiO2, H2O2/TiO2/UV, O3/TiO2/UV); the Fenton reaction-based processes (Fe2+/H2O2...
Copper-mediated damage to the mitochondrial respiratory chain causes hyperactivation of the energy sensor AMPK, which accelerates cuproptosis and the release of the pro-inflammatory mediator HMGB1. ATP7B, ATPase copper transporting beta; DLAT, dihydrolipoamide S-acetyltransferase; FDX1, ferredoxin 1; LA...
Theoretically, increasing the concentration of the catalyst causes an increase in the degradation rate through providing more active site of the catalyst and accelerates the generation of hydroxyl radical31, whereas, above certain amount, the excessive ZnO NPs decrease light penetration and increase ...
The cooperative catalysis between lipase-active site and single Pd atom accelerates alkyl-alkyl cross-coupling reaction between 1-bromohexane and B-n-hexyl-9-BBN with high efficiency (TOF is 540 h−1), exceeding that of the traditional catalyst Pd(OAc)2 by a factor of 300 under ambient...
“That’s the default assumption, that the forward and reverse reactions contribute equally to the reaction rate,” Surendranath says. “Our finding is really eye-opening because it means that the assumption that people are using to analyze everything from fuel cell catalysis to h...
In order to figure out how the coordinated phosphate promoted the SOD-like activity, we carried out DFT calculations to uncover the reaction processes on ferrihydrite and phosphate-doped ferrihydrite. Because superoxide anion O2•−readily protonates to form HOO•in aqueous condition50, the HOO...
active compounds37and fluorophores38. Because a catalyst such as1is required for this reaction to proceed, the product coumarin10should be formed only when there is a sufficiently high concentration of1in solution, causing the concentration of10to oscillate in tandem with that of catalyst1. ...
