Spectroscopic and electrochemical study of the redox process of poly(2,2'-dithiodianiline)
Cotarelo Méndez, María de los Ángeles - Huerta Arráez, Francisco - Quijada Tomás, César - Pérez Martínez, José María - Valle de la Cortina, María Angélica del - Vázquez Picó, José Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	The redox process undergone by the electrochemically synthesized poly(2,2-dithiodianiline), poly(DTDA), has been examined in acetonitrile-water mixtures by electrochemical and spectroscopic techniques. The spectroscopic properties of this material are equivalent to those exhibited by the chemically synthesized one. The polymeric structure…

Redox flow cells for energy conversion
Ponce de León Albarrán, Carlos - Frías Ferrer, Ángel - González García, José - Szánto, D.A. - Walsh, Frank C.

Formato:	info:eu-repo/semantics/article
Enlaces:	Energy storage technologies provide an alternative solution to the problem of balancing power generation and power consumption. Redox flow cells are designed to convert and store electrical energy into chemical energy and release it in a controlled fashion when required.…

Target inner-shells contributions to the stopping power and straggling for H and He ions in gold
Heredia Ávalos, Santiago - Abril Sánchez, Isabel - Denton Zanello, Cristian D. - Moreno Marín, Juan Carlos - García Molina, Rafael

Formato:	info:eu-repo/semantics/article
Enlaces:	The electronic energy loss of swift H and He ions in gold is studied, paying special attention to the contribution to the projectile energy loss due to the ionization of the target inner-shells. We calculate the stopping power and the…

An improved 'heuristic' approximation for the period of a nonlinear pendulum: linear analysis of a classical nonlinear problem
Beléndez Vázquez, Augusto - Hernández Prados, Antonio - Beléndez Vázquez, Tarsicio - Márquez Ruiz, Andrés - Neipp López, Cristian

Formato:	info:eu-repo/semantics/article
Enlaces:	A new analytical approximate expression for the period of the simple pendulum is obtained by using a heuristic but pedagogical derivation. This formula depends on two parameters obtained by comparing term-by-term the power-series expansions of the approximate and exact expressions…
