Since this study was carried out in the laboratory for machines of the Institute of Agricultural Engineering, only clean air was available. As a result, no measurement could be done for removal efficiency (e.g. ammonia). The exchange scrubber pilot-plant was a module of a full-scale ...

In this embodiment, a titanium film is used as the conductive film and an In—Ga—Zn—O-based oxide semiconductor is used as the oxide semiconductor layer 403, and therefore, the conductive film is selectively etched by using ammonium hydrogen peroxide (a mixture of ammonia, water, and hydrog...
Here, a titanium film is used as the metal conductive film, an In—Ga—Zn—O based oxide is used for the oxide semiconductor layer 431, and an ammonia hydrogen peroxide mixture (a mixed solution of ammonia, water, and a hydrogen peroxide solution) is used. Note that, in the third photo...
The synthesis of Mg-doped GaN powders, 5.874 g (84.24 mmol) of metallic gallium, and 0.059 g (2.44 mmol) of metallic magnesium, which was also approximately 1% in the incorporation, were used as reagents. Additionally, anhydrous ammonia (NH3) was used as the source of nitrogen atoms in ...
l-Cysteine is an important sulfur-containing amino acid with numerous applications in the pharmaceutical and cosmetic industries. The microbial production of l-cysteine has received substantial attention, and the supply of the precursor l-serine is impor

However, we can see some interesting observations regarding the correlations of the Ammonia (NH3) gas level (i.e., MQ139) with both eCO2 and TVOC. Both eCO2 and TVOC are strongly correlated with MQ139. When building a machine learning predictive model, one could consider removing one of ...
one unit causes the formation of two micromoles of ammonia per minute at pH 8.0 at 37 °C) was about 276 u/mg at 37 °C. In order to precisely control the urease activity in each sample during the test, a certain amount of urease powder was dissolved into a dilute solution of 13.8...
It should be stressed, however, that the absolute levels of NOx for the vehicle were quite low, only half of the applicable limit (60 mg/km for NOx). Ammonia (NH3) emissions (11 mg/km) from the GPF-equipped GDI vehicle studied were 2 times lower than what has been reported for ...
