The conversion of ammonia improved from 16 % to 25 %, while the current efficiency for the consumption of ammonia increased from 92 +/- 1 % to 97 +/- 2 % by using PAA-K in lieu of KOH. The use of PAA-K also prevented the crossover of the hydrogen produced to the anode side, ...

Moreover, although the current density was much higher when the potential was below −0.70 V, which is more appropriate for the electrochemical reaction, the hydrogen evolution reaction was dominant at the potential below −0.80 V and the production yield of NH3 was very low. Meanwhile, the...
DNA damage inducible protein (DDIP) exhibited a noticeable upregulation (p = 0.0011) with concurrent exposure to ammonia, arsenic, and high-temperature stress. This was followed by the group exposed to ammonia and high temperature, and then the arsenic and ammonia, ammonia alone, and arseni...
Direct conversion of atmospheric nitrogen and hydrogen to ammonia with plasma requires a significant amount of energy and has a low product selectivity [9], [10]. This is because dissociating N2 molecules through plasma whilst preventing the decomposition of produced ammonia is difficult to achieve ...
BILBAO,Spain--(BUSINESS WIRE)--H2SITE has successfully validated the first ammonia cracker to produce high-purity hydrogen for onboard power genera

The influence of the hydrogen-ion concentration on the growth and metabolism of a highly acid-resistant green alga, Chlorella ellipsoidea (strain Marburg St), was studied. Chlorella pyrenoidosa (Emerson strain) served as a normal control... E Kessler,H Kramer - 《Archiv Für Mikrobiologie》 被...
situ optical microscopy, bubbles are hardly observed on the CoP-CNS at each applied potential during the NITRR process (Supplementary Fig.27). The above results suggest the outstanding NH3production efficiency and selectivity of CoP-CNS. Active hydrogen promotes the NITRR to produce NH3...
More importantly, this high nitrate-reduction catalytic activity enables over a 99% nitrate conversion into ammonia, from an industrial wastewater level of 2,000 ppm to a drinkable water level <50 ppm, while still maintaining an over 90% Faradaic efficiency. Coupling the nitrate reduction ...
