애플리케이션

Sodium citrate tribasic dihydrate can be used as a catalyst to synthesize:     
  • Fused O- and N-heterocyclic derivatives via multicomponent Knoevenagel-cyclocondensation of isatin/aldehyde/ acenaphthylene-1,2-dione, malononitrile, and various C−H activated acids.     
  • Chromeno[3′,4′:5,6]pyrano[2,3-d]pyrimidines by the condensation reaction of 4-hydroxycoumarin, aromatic aldehydes, and barbituric acid/thiobarbituric acid.

It can also be used as:      
A reducing agent to synthesize metal nanoparticles via sol-gel method using corresponding metal salt precursors.    
A controlling agent in the synthesis of single-crystal of coordination polymer [Co(H2O)2Ni(CN)4 4H2O].

Complex coacervation is an emerging liquid/liquid phase separation (LLPS) phenomenon that behaves as a membrane-less organelle in living cells. Yet while one of the critical factors for complex coacervation is temperature, little analysis and research has been devoted to the

The use of conventional membrane adsorbers such as radial flow devices is largely restricted to flow-through applications, such as virus and endotoxin removal, as they fail to give acceptable resolution in bind-and-elute separations. Laterally-fed membrane chromatography or LFMC devices have
