Materials scientists at the University of Wisconsin-Madison have discovered a phenomenon—the direct conversion of mechanical energy to chemical energy—which they termed the piezoelectrochemical (PZEC) effect. They then applied the PZEC effect to generate hydrogen and oxygen via direct water splitting.

The new pretreatment approach uses ammonia (NH 3 ) to reorganize the hydrogen bond network within cellulose, resulting in up to a 5-fold increase in saccharification rates. This, in turn, significantly reduces the tightness of the cellulose network and leaves it more vulnerable to conversion into sugar by fungi-derived cellulolytic enzymes.

Conversely to the effect on diesel fuel, the additive shifts the distillation curve of gasoline to higher temperatures. We note that this issue may have more importance operationally than we have been able to ascribe to our volatility measurements alone. The extent of these shifts is proportional to the amount of additive in the mixtures.
