A water source ‘s pH value is a function of its acidity, or alkalinity. The pH level is a function of the hydrogen atom activity, as the hydrogen activity is a reasonable indicator of the water’s acidity or alkalinity. As seen below, the pH scale ranges from 0 to 14 when 7.0 is ...
The pH scale is not a linear measure of the proton concentration but a logarithmic one. In fact, the “p” in “pH” stands for the negative base 10 logarithm and “H” stands for the concentration of H+. This means that a change of 1 pH unit doesn't change the proton concentration...
To apply biohybrid microrobots in applications in bioengineering and medicine, reliable and efficient control of the microrobot at the swarm scale is a critical step. Our demonstrations of robust drift control using pH gradients expand the current scope of bacteria-propelled microrobotic control methods....
Signal processing by intracellular kinases controls near all biological processes but how signal pathway functions evolve with changed cellular context is poorly understood. Functional specificity of c-Jun N-terminal Kinases (JNK) are partly encoded by s
We show that the strongest constraint on the tension of string is obtained from the quadrupolar anisotropy and argue that the mass scale of underlying theory responsible for the formation of string can not be much higher than the GUT scale. The predictions of string for the diagonal and off-...
pH value is a crucial indicator for evaluating silage quality. In this study, taking maize silage as the research object, a quantitative prediction model of pH value change during the secondary fermentation of maize silage was constructed based on computer vision. Firstly, maize silage samples were...
As can be seen from the results of this case study below, the developed framework succeeded in providing a consistent integration between a hardware/software infrastructure and an industrial-scale control process. Through this integration, the effect of the control logic, which was implemented in Pyt...
methyl orange- an azo dye used as an acid-base indicator; used for titrations involving weak bases indicator- (chemistry) a substance that changes color to indicate the presence of some ion or substance; can be used to indicate the completion of a chemical reaction or (in medicine) to test...
PH is a scale of hydrogen ion activity in solution, that is, the standard of acidity and alkalinity of solution in common sense. The more the pH value tends to 0, the stronger the acidity of the solution is, otherwise, the more tends to 14, the stronger the alkalinity of the solution...
The mathematical definition of pH is a bit less intuitive but in general more useful. It says that the pH is equal to to the negative logarithmic value of the Hydrogen ion (H+) concentration, or pH = -log [H+] pH can alternatively be defined mathematically as the negative logarithmic ...
