Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In Vietnam, traditional distilled rice alcohol is often produced at the household scale with limited sanitary conditions, leading to low yield, unstable, and moderate‐quality alcohol products. No‐cook or Simultaneous liquefaction, saccharification, and fermentation (SLSF) technology has shown to be very promising thanks to its advantages such ...

Carbon Energy, EarlyView.ABSTRACT The inherent hydroxide‐rich (OH⁻) environment in alkaline media facilitates the two‐electron oxygen reduction reaction (2e−ORR). However, the strong interaction between alkali metal cations and solvated water molecules significantly reduces the connectivity of the hydrogen bond network within the alkaline electric double layer, thereby ...
