Sensors | Free Full-Text | Ammonia Sensing Behaviors of ...

The ammonia sensing behaviors of the sensors were examined at room temperature. All the results indicated that the ammonia sensing property of TiO2-PANI/PA6 composite nanofibers was superior to that of PANI/PA6 composite nanofibers. TiO2-PANI/PA6 composite nanofibers had good selectivity to ammonia. It was also found that the content of TiO2 had a great influence on both the morphology …

Ammonia in Refrigeration Systems in Ice Arenas A.

Ammonia’s fire hazard rating is usually stated as “slight” as it is only explosive in air at concentrations of 16–27 percent (by volume). B. How does the ammonia act as a Refrigerant? In ice arenas the ammonia refrigerant is in a closed loop which essentially means it is contained within the system. In most typical refrigeration systems the cold ammonia is circulated or flooded around

Bioelectronic protein nanowire sensors for ammonia detection

alternative active component of electronic sensors [47, 48]. Protein nanowires were shown to be highly responsive to pH with a widely tunable conductivity, indicating the effect of proton doping [49, 50]. Since ammonia is known to modulate protonation, protein nanowires may be a promising candidate for highly sensitive and selective ammonia sensing. In addition, protein nanowires can be ...
