The dyeing of paper is one of the most important
processes in the manufacture of that material. Fully 95 percent
of the paper that is produced is colored to a greater or
lesser extent, and in many eases the reproduction of a shade
is essential. That pH is an important...
I have developed an analytical method for the determination of
molecular hydrogen in seawater. It is based on the change of hydrogen
concentration in a 30 cc. volume of air as it is equilibrated with a
one-liter sample of seawater. The change in hydrogen concentration in
the air is measured...
Microbial lethality is strongly pH dependent in processing regimes including
high hydrostatic pressure processing (HPP). HPP induces the dissociation of
weak acids that potentially causes a shift in pH in some systems thereby increasing
acidity while pressure insensitive buffers do not undergo dissociation. The
degree of high pressure induced pH...
