Pepped up: Notwithstanding the intrinsic conformational flexibility of peptides, [Zn(Gly-Thr)(2) ] behaves as a robust porous metal-organic framework thanks to the rigidity introduced by the use of Gly-Thr. This rigidity arises from the sequence of amino acids in the dipeptide that locks its conformational flexibility in the framework.

Although the coexistence of superconductivity and ferromagnetism in one compound is rare, some examples of such materials are known to exist. Methods to physically prepare hybrid structures with both competing phases are also known, which rely on the nanofabrication of alternating conducting layers. Chemical methods of building up hybrid materials...
