Analysis of ammonium in micas by Electron Energy-Loss Spectroscopy Abad, Isabel Livi, Keneth Nieto García, Fernando Arkai, Peter Judik, Katalin EELS NH4 Micas Tobelite Recent developments in electron energy-loss spectroscopy (EELS) has made it possible to directly locate and measure the compositions of NH4+ micas down to the nanometer scale. We have developed and tested methods for detecting N in micas also containing K. 2020-11-10T13:12:00Z 2020-11-10T13:12:00Z 2007 info:eu-repo/semantics/conferenceObject Seminarios de la Sociedad Española de Mineralogía, V.3; 99 (Nieto y Jiménez-Millán, Eds.) http://hdl.handle.net/10481/64180 eng Seminarios de la Sociedad Española de Mineralogía; http://creativecommons.org/licenses/by-nc-nd/3.0/es/ info:eu-repo/semantics/openAccess Atribución-NoComercial-SinDerivadas 3.0 España
