Autor: M. Guadalupe Olayo, Guillermo J. Cruz, Elena Colín-Orozco, Rosario Mejía-Cuero, Lidia M. Gómez, J. Cuauhtémoc Palacios, Maribel González-Torres

Publikováno v: Journal of Nanoparticle Research. 23

CuOx, CoOy, and bimetallic CoCuOz nanoparticles with diameter between 54.6 and 111.4 nm were synthesized by sol-gel and eroded with Ar ions to identify and quantify the oxide structures formed in the particles. Oxidation was estimated by XPS calculat

Liquid Plasma Iodine Doping of Electrochemically Synthesized Polypyrrole to Enhance the Electromagnetic Absorption

Autor: Hilda Moreno-Saavedra, Ma. Guadalupe Olayo, Guillermo J. Cruz, C. Hernandez-Tenorio, Miguel Villanueva-Castañeda

Publikováno v: Journal of Inorganic and Organometallic Polymers and Materials. 30:2098-2104

Polypyrrole (PPy) was electrochemically synthesized and doped with plasma glow discharges on a liquid solution with iodine to enhance the electromagnetic absorption and the transference of electrical charges in the polymer. The results indicated that

Alpha emitters in the beach sands of the Mexican Pacific littoral

Autor: Guillermo J. Cruz, María Guadalupe Almazán-Torres, Eduardo Ordóñez-Regil

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 321:421-426

Alpha emitters in Mexican Pacific beach sands were studied to calculate the 234U/238U activity ratio (AR) and the 239+240Pu content. AR was related with the weathering conditions of the sands; AR = 1 means reduced weathering conditions, like those fo
