Download or read book Tables for Emission Spectrographic Analysis of Rare Earth Elements written by Ch. Kerekes and published by Elsevier. This book was released on 2013-10-22 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlas and Tables for Emission Spectrographic Analysis of Rare Earth Elements focuses on the analysis of rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion. The book first offers information on the division of the spectra of rare earth elements and Sc and Y into three groups. The spectra of Ce, Pr, Nd, Gd, Tb, Dy, Ho, and Er have lines that, however, do not form characteristic line groups. The text underscores that in preparing the Atlas, the spectral pure-grade rare earth oxides sold by the Johnson & Matthey Co. were considered. Through the help of their spectra, the usable analysis lines and the wavelength values of the interfering spectral lines are created. The operating and photographic conditions are tabulated. The book stresses that for each rare earth, the analysis lines are provided in order of decreasing wavelength. The number located in the lower left corner for each analysis line indicates its relative intensity. The fifteen columns contain the interfering lines of other rare earths and of Sc and Y. The interfering lines are created through the use of the double projector of the Optica Milano Co. and the Gatterer Spectrum. The text is a great source of information for readers wanting to analyze rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion.

Download or read book Las tierras raras written by Ricardo Prego Reboredo and published by LOS LIBROS DE LA CATARATA. This book was released on 2019-03-12 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Los diecisiete elementos que componen las tierras raras empezaron a descubrirse a finales del siglo XVIII, pero no fue hasta después de la Segunda Guerra Mundial cuando se avanzó en sus aplicaciones. Ahora tenemos tierras raras en los billetes de euro para evitar falsificaciones y en los teléfonos móviles para que sean táctiles y emitan sonido y luz. En nuestra tecnificada cultura la lista de artículos que las contienen es muy extensa. Son indispensables para las tecnologías verdes, los coches híbridos y las turbinas eólicas; hacen posible imanes más potentes y de menor peso que permiten electrodomésticos cada vez más pequeños; se necesitan para fabricar gafas de visión nocturna, misiles crucero y otras armas... ¿Cómo ha avanzado nuestro conocimiento sobre las tierras raras hasta llegar a la gran dependencia actual? Esta obra aborda el camino seguido desde el desinteresado descubrimiento científico de algunas tierras raras en la mina del pueblo sueco de Ytterby hasta hoy en día, cuando se han convertido en costosos metales que son tecnológicamente críticos para nuestra sociedad.

Available in PDF, EPUB and Kindle. Book excerpt: Adéntrate en el intrigante universo de las tierras raras, un grupo de diecisiete elementos químicos que desempeñan un papel trascendental en nuestra vida cotidiana y en la industria moderna. Descubiertos a partir del siglo XVIII, estos desconocidos elementos químicos han multiplicado su valor actual gracias a sus excepciona-les propiedades, tales como la conductividad térmica, susceptibilidad magnética y fluorescencia. Sin embargo, su extracción y procesamiento presentan desafíos técnicos y complejas implicaciones geopolíticas, relacionadas con el acceso a las reservas y la protección de los derechos humanos. Estos elementos se han convertido en pilares fundamentales de la tecnología moderna, desempeñando un papel crucial en productos como teléfonos móviles, turbinas eólicas, automóviles eléctricos y aplicaciones militares. A medida que la demanda crece y se desarrollan nuevas tecnologías, los proveedores de tierras raras enfrentan una creciente presión y precios volátiles. Este libro ofrece un análisis profundo de las tierras raras, explorando su historia, propiedades, aplicaciones e importancia, así como los desafíos en su extracción y un detallado examen geopolítico que abarca aspectos económicos, sociales y ambientales. Te brinda una apasionante introducción a elementos esenciales en nuestra sociedad, que nos impulsan hacia un mundo más moderno y limpio, donde las tierras raras son en buena medida la base de nuestro progreso.

Available in PDF, EPUB and Kindle. Book excerpt: The Phenomenological Mind is the first book to properly introduce fundamental questions about the mind from the perspective of phenomenology. Key questions and topics covered include: • what is phenomenology? • naturalizing phenomenology and the cognitive sciences • phenomenology and consciousness • consciousness and self-consciousness • time and consciousness • intentionality • the embodied mind • action • knowledge of other minds • situated and extended minds • phenomenology and personal identity. This second edition includes a new preface, and revised and improved chapters. Also included are helpful features such as chapter summaries, guides to further reading, and a glossary, making The Phenomenological Mind an ideal introduction to key concepts in phenomenology, cognitive science and philosophy of mind.
