Fabrication and spectroscopic investigation of sandwich-like ZnO:rGO:ZnO:rGO:ZnO structure by layer-by-layer approach por Pandiyarajan, Thangaraj, Viswanathan Mangalaraja, Ramalinga, Karthikeyan, Balasubramanian, Arulraj, Arunachalam, Gracia Pinilla, Miguel Ángel

“…The lower energy shift of near band edge (NBE) emission and reduction in the emission intensity with respect to pure ZnO nanostructures was observed. The present work provides a simple layer-by-layer approach to fabricating sandwich structures and improving the optical properties which have potential applications in various optoelectronic devices.…”

Omega fatty acids production in an isolated native Chlorella sp. from northeast Mexico with improved growth using urine as nutritive medium por Canino Gómez, Jessica Cossette, Limón Rodríguez, Benjamín, Rivas García, Pasiano, Escamilla Alvarado, Carlos, Morones Ramírez, José Rubén, Alcalá Rodríguez, Mónica María

“…An improvement was also observed in the production of fatty acids and proteins, where the cultivation of Chlorella sp. with the urine medium (MOB) showed an average production (%) of 17.22% saturated fatty acids (SUFA’s), 22.03% of monounsaturated fatty acids (MUFA’s) and 60.73% of polyunsaturated fatty acids (PUFA’s), demonstrated also in the high concentrations of mainly linoleic and linoleic fatty acids in the microalgae. …”

Low temperature synthesis of hexagonal Bi2Te3 nanoplates using an open reactor and its effect on their physicochemical properties por Reyes Verdugo, Laura A., Martinez Carreon, Maria de J., Gutiérrez Lazos, C. D., Solis Pomar, Francisco J., Quiñones Galvan, Jose G., Pérez Tijerina, Eduardo

“…A vibrational mode at 120 cm−1 due to the breaking of the symmetry of the Bi2Te3 crystal along the C axis was observed by Raman spectroscopy. XPS results showed that despite the strong reactivity of Te2− ions with ambient oxygen, the crystallization of Bi2Te3 hexagonal nanoplates is feasible without controlled vapor pressure and at a lower temperature than reported in other works. …”

Study of structural properties of BiOI on ZnO thin films and ZnO nanorods por Gutiérrez Lazos, C. D., Fundora Cruz, A., Solís Pomar, F., Pérez Tijerina, E.

“…The scanning electron microscopy analysis showed that BiOI grew on the ZnO-NR surfaces in nanoplatelet shape with an order of magnitude smaller in size, with respect to the platelets observed in BiOI thin films. Analysis by X-ray diffraction exhibited the hexagonal P63mc phase of ZnO and the tetragonal P4nmm crystal phase of BiOI. …”

FePt icosahedra with magnetic cores and catalytic shells por Wang, Rongming, Dmitrieva, Olga, Farle, Michael, Dumpich, Güntner, Acet, Mehmet, Mejía Rosales, Sergio, Pérez Tijerina, Eduardo, Yacamán, Miguel José, Kisielowski, Christian

“…Computational studies and energy-filtered transmission electron microscopy analyses suggest that a Pt-enriched surface layer is energetically favored and that site-specific vacancies are formed at the edges of facettes, which was experimentally observed. The presence of the Pt-enriched shell around an Fe/Pt core explains the environmental stability of the magnetic icosahedra and strongly reduces the exchange coupling between neighboring particles, thereby possibly providing the highest packing density for future magnetic storage media based on FePt nanoparticles.…”
