According to the specific energy content of the fuel, anhydrous ethanol is expected to reduce the fuel economy (km/L) of vehicles. However, since ethanol fuel has a high octane number (ON), about 120 and thus much higher than gasoline (87–98), it has better combustion efficiency [26]....

Internal Energy For an ideal gas the internal energy - u - is a function of temperature. A change in internal energy can be expressed as du =cv dT (1) where du = change in internal energy (kJ/kg) cv = specific heat for gas in a constant volume process (kJ/kgK) dT = change in...
Briefly, after 14 days of the sample incubation in a simulated body fluid (SBF) at 37 °C, apatite crystals that formed on the granules’ surfaces were visualized using SEM (JEOL JCM-6000Plus or FEI Nova NanoSem 450), equipped with an Octane Pro EDS (energy dispersive spectroscopy) ...
It not only directly participates in cell metabolism and signal transduction, but also has a close relationship with energy metabolism (Zhang et al., 2020). Insufficient supply of phosphatidylglycerol can damage cell membranes and reduce the synthesis of acetylcholine, leading to symptoms such as ...

The 7,8-epoxy-1-octene then undergoes a second oxidation catalyzed by alkane hydroxylase to form (R)-1,2:7,8-diepoxyoctane with an enantiomeric purity of 83%. These observations led to industrial applications for the synthesis of the drugs Metoprolol and Atenolol (Archelas et al., Annual ...
