Crystalline structure and thermotropic behavior of alkyltrimethylphosphonium amphiphiles
Gamarra Montes, Ana; Urpí Garriga, Lourdes; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Muñoz Guerra, Sebastián (2017-02-14)
Article
Open AccessQuaternary organophosphonium salts bearing long alkyl chains are cationic surfactants of interest owing to their physical and biological properties. In the present work, the crystal structure and thermotropic behavior of ... -
DNA coiled coil superstructures in oligonucleotide crystals
Luchi, Daniela de; Urpí Garriga, Lourdes; Subirana Torrent, Juan A.; Campos López, Josefina de Lourdes (American Chemical Society (ACS), 2011-05-04)
Article
Restricted access - publisher's policyWe present the structure of coiled coils found in two oligonucleotide DNA crystals. The sequences d-(ATATATATAT) and d(CGATATATAT) are used. In the first case several coiled coils with different structures are found. In ... -
