Autor: Kopelevich, Y. V., Torres, J. H. S., da Silva, R. Ricardo, Diamantini, M. C., Trugenbergerand, C. A., Vinokur, V. M.

Publikováno v: Adv. Quantum Technol. 2023, 2300230

Room temperature superconductivity under normal conditions has been a major challenge of physics and material science since its very discovery. Here we report the global room-temperature superconductivity observed in cleaved highly oriented pyrolytic

Vortex Lattice in Bi_{2}Sr_{2}CaCu_{2}O_{8+\delta} Well Above the First-Order Phase-Transition Boundary

Autor: Torres, J. H. S., da Silva, R. Ricardo, Moehlecke, S., Kopelevich, Y.

Publikováno v: Solid State Communitations 125, pp. 11-16 (2003)

Measurements of non-local in-plane resistance originating from transverse vortex-vortex correlations have been performed on a Bi_{2}Sr_{2}CaCu_{2}O_{8+\delta} high-T_c superconductor in a magnetic field up to 9 T applied along the crystal c-axis. Our

Evidence for internal field in graphite: A conduction electron spin resonance study

Autor: Sercheli, M. S., Kopelevich, Y., da Silva, R. Ricardo, Torres, J. H. S., Rettori, C.

We report conduction electron spin resonance measurements performed on highly oriented pyrolitic graphite samples between 10 K and 300 K using S (f = 4 GHz), X (f = 9.4 GHz), and Q (f = 34.4 GHz) microwave bands for the external dc-magnetic field app

Indication of Superconductivity at 35 K in Graphite-Sulfur Composites

Autor: da Silva, R. Ricardo, Torres, J. H. S., Kopelevich, Y.

Publikováno v: Phys. Rev. Lett. 87, 147001 (2001)

We report magnetization measurements performed on graphite--sulfur composites which demonstrate a clear superconducting behavior below the critical temperature T$_{c0}$ = 35 K. The Meissner-Ochsenfeld effect, screening supercurrents, and magnetizatio

Fatiga del material de los sistemas de ventilación mecánica como factor de riesgo en neumonía asociada a ventilación mecánica

Autor: NAVARRETE C, MARITZA, CALVO A, MARIO, GUTIÉRREZ E, ANGÉLA, SILVA R, RICARDO, GARCÍA A, CYNTHIA, CEA G, MARIBETH, CRUZ P, CAROLINA, ARCE G, M EMILIA, ZAROR C, ANGELA, LIZAMA A, VICTOR, ANSORENA V, AIDA

Publikováno v: Revista chilena de infectología, Volume: 21, Issue: 1, Pages: 09-16, Published: 2004

La neumonía asociada a ventilación mecánica (NAVM) en Chile, es una de las infecciones intrahospitalarias (IIH) más frecuentes y de mayor impacto en morbimortalidad. A pesar de las medidas habituales de prevención de IIH aplicadas en nuestro hos
