Twenty-five derivatives of glycyrrhetinic acid(GA) modified on the A-ring,at C30 and C11 positions were synthesized.Their in vitro cytotoxicity against various
α-Fe2O3 nanoparticles doped with various molar fractions of Cr3+ were synthesized by a forced hydrolysis route and were characterized by X-ray diffraction(XRD)
A new manganese(II) phosphite,Mn 2 F2(HPO3)(1),was synthesized with tetraethylene pentamine as structure directing agent under hydrothermal conditions.The as-sy
