Recovery of Acid and Base from Sodium Sulfate Containing Lithium Carbonate Using Bipolar Membrane Electrodialysis

Membranes, 2021
Lithium carbonate is an important chemical raw material that is widely used in many contexts. The preparation of lithium carbonate by acid roasting is limited due to the large amounts of low-value sodium sulfate waste salts that result. In this research,

Shoot yield drives phosphorus use efficiency in Brassica oleracea and correlates with root architecture traits [PDF]

, 2009
The environmental and financial costs of using inorganic phosphate fertilizers to maintain crop yield and quality are high. Breeding crops that acquire and use phosphorus (P) more efficiently could reduce these costs.

On the efficiency and reliability of high-current rectifiers

2008 IEEE Power Electronics Specialists Conference, 2006
Industrial electrolytic rectifiers work with high currents (in the order of kilo Amps) and very low dc voltage levels (few hundred Volts). The preferred industrial solutions for this type of application are thyristor-based double-bridge and four-star multi-pulse rectifiers.
