General description
Monobasic potassium phosphate crystals are colorless, soluble in water and hygroscopic in nature.Upon heating through 187°C, phase transition occurs in KH2PO4, crystal system changes from tetragonal to monoclinic, lattice parameters at 195°C are α=7.47Å, b =7.33Å, c =14.49Å, α=β=90° and γ=92.2.

A facile method is developed to synthesize intrinsically fluorescent carbon dots by hydrothermal treatment of glucose in the presence of monopotassium phosphate. The fluorescence emission of the carbon dots thus produced is tunable by simply adjusting the concentration of monopotassium

Lipidic cubic phases (LCPs) have emerged as successful matrixes for the crystallization of membrane proteins. Moreover, the viscous LCP also provides a highly effective delivery medium for serial femtosecond crystallography (SFX) at X-ray free-electron lasers (XFELs). Here, the adaptation of
