Scientists have found a way to more than double the uptake ability of a chemical structure that can be used for scrubbing carbon dioxide from factory flues.
This study presents an all-polymer aqueous sodium-ion battery using PANI electrodes, achieving high stability and capacity for sustainable energy storage.
However, conventional processes (chelation-gel process) require a significant excess of the acid, and the pH value must constantly be adjusted with ammonia—complicated and not very environmentally ...
The one we use, clinoptilolite, is one of over 40 different zeolites. It can remove certain ions from the water, such as ammonium, phosphate and calcium, via two processes: adsorption and ion exchange ...
For negative ion model, 2 mM ammonia acetate (buffer A) and acetonitrile (buffer B) were used, following the same elution schedule as above. The flow rate was 0.4 mL/min. For mass spectrometry, an ...
