Selective acceleration and inhibition of crystal growth of glass carbamazepine by low-concentration poly(ethylene oxide):effects of drug polymorph

Low-concentration poly(ethylene oxide) effects both the surface and bulk crystal growth of carbamazepine polymorphs. These polymorph-dependent effects are mainly attributed to the polymer enrichment at the interface and different crystal surface–polymer interactions.

A rare case of Na/Zn isomorphism in the crystal structure of non-centrosymmetric zincophosphate Na₅Zn[Zn(PO₄)₃]

Na₅Zn[Zn(PO₄)₃] with a new structure type represents a rare case of Na/Zn isomorphism.

Structural and magnetic phase transitions in Eu_1–xLa_xFe₃(BO₃)₄ (x = 0, 0.18)

The structural behaviour of EuFe₃(BO₃)₄ and lanthanum-doped EuFe₃(BO₃)₄ crystals has been studied with respect to tem­per­a­ture using X-ray fluorescence analysis, single-crystal X-ray diffraction, Mössbauer spectroscopy and specific heat capacity measurements. Structural and magnetic phase transitions have been discussed.
