Electrochemical behaviour of amino acids on Pt(h, k, l): a voltammetric and in situ FTIR study. Part II. Serine and alanine on Pt(111)
Huerta Arráez, Francisco - Morallón Núñez, Emilia - Cases Iborra, Francisco Javier - Rodes García, Antonio - Vázquez Picó, José Luis - Aldaz Riera, Antonio

Formato:	info:eu-repo/semantics/article
Enlaces:	A spectroelectrochemical study of the adsorption and oxidation of serine and alanine on Pt(111) electrodes has been carried out in 0.1 M HClO4 solutions. From the voltammetric and FTIR spectroscopic results, we concluded that adsorbed cyanide is formed at 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…

Does the invasion of Caulerpa racemosa var. cylindracea affect the feeding habits of amphipods (Crustacea: Amphipoda)?
Vázquez Luis, Maria Teresa - Sánchez Jerez, Pablo - Bayle Sempere, Just T.

Formato:	info:eu-repo/semantics/article
Enlaces:	Ecological interactions involving introduced seaweeds constitute an important research gap, since they could alter the trophic dynamics of native populations, but indirect effects on trophic levels are poorly known. The seaweed Caulerpa racemosa is one of the most notable invaders…

Durability improvement of ancient bricks by cementation of porous media
López Arce, Paula - Benavente García, David - García Guinea, Javier

Formato:	info:eu-repo/semantics/article
Enlaces:	The physicomechanical properties of historic bricks in Toledo (Spain) that have undergone a time-dependent self-healing by natural weathering processes have been improved by porous infill with gypsum, ettringite, and, mainly, calcite. Both these bricks and their experimental replica bricks, made…
