Since pH has been used universally in food physics and chemistry for well over a century, not much thought is given to its actual meaning, but rather pH is only associated with a certain outcome or desired product. Therefore, this review covers the fundamental understanding of pH, its measurem...

Full size table Structural differences between the high-pH and low-pH complex Interestingly, the high-pH EmrE-TPP complex exhibits numerous structural differences from the low-pH complex (Fig.4and Supplementary Fig.7). First, the ligand is more symmetrically positioned between the two E14 residues...
Full size image The MoS2/Mo2C sample shows comparable HER performance in both alkaline and acidic media, but the Pt foil and MoS2samples show poorer HER performance in alkaline than in acidic media, which stems from differences in their surface chemistry. To reveal the role of surface chemistry...

There is one example in which phenolphthalein and o-cresolphthalein 284 have been polymerized with formaldehyde to form phenol...

Most freshwater aquariums sit around an average pH of 7.0. Most fish can tolerate a range of 6.5 – 7.5, though this will vary with species. As mentioned before, most tropical species, like tetras, will prefer more acidic water chemistry. On the other hand, African cichlids are known for ...
It took about 5.5 h to obtain a full separation of crude oil from this crude O/W nanoemulsion. Moreover, there were 41 and 0% demulsification of the crude O/W nanoemulsions stabilized by 2 and 4 wt% biosurfactant, respectively, within the first 6 days from the addition of 0.5 M NaOH....
