Radiación de neutrones y sincrotrones y los metales

Metals Challenged by Neutron and Synchrotron Radiation. Klaus-Dieter Liss (Ed.). 2018. ISBN: 978‐3‐03842‐647‐9. 288 p.
ACCESO AL LIBRO

Neutron and Synchrotron radiation methods have matured to become powerful techniques for the study of a vast range of materials, including metals. The characterization methods comprise the categories of diffraction, spectroscopy and imaging, which themselves can alter greatly in detail, to include hundreds of variants, problems and sample environments. In a similar way, their applications to metals and hard condensed matter materials cover disciplines spanning engineering, physics, chemistry, materials science and their derivatives such as geology, energy storage, etc. … The present book, “Metals Challenged by Neutron and Synchrotron Radiation” is a first compilation in Metals of 20 original and review works on research utilizing or designing those state-of-the-art techniques at modern facilities. The Editorial reviews the context of and identifies thematic links between these papers, grouping them into five interwoven themes, namely Sintering Techniques and Microstructure Evolution, Titanium Aluminides and Titanium Alloys Under Extreme Conditions, Metallic Glass and Disordered Crystals, In Situ and Time-Resolved Response to Mechanical Load and Shock, and Thin Films and Layers. This book represents a good cross-section of the status quo of neutron and synchrotron radiation with respect to questions in the metallurgical field, which by far is not exhaustive. Nor are the methods and other materials, which motivated me to the creation of a new sister-journal, entitled Quantum Beam Science. With this, I would like to thank all authors, reviewers and contributors behind the scene for the creation of this work, presenting to you a piece of interesting reading and reference literature.

ACCESO AL LIBRO

Este libro cubre aspectos y logros del componente bariónico (estrella y gas) de los halos de galaxias. Puede considerarse como un compendio de los resultados destacados en este campo. El enfoque principal son las últimas simulaciones y observaciones de halos de galaxias. Este compendio se recomienda a los investigadores y estudiantes avanzados, ya que contiene trabajos revisados por pares de alta calidad que satisfacen sus necesidades científicas y ayudan a iniciar nuevas direcciones de investigación.

Atrapar CO2

Omar Yaghi (Amán, 1965), jordano-estadounidense, afirma que las medidas en marcha para frenar el cambio climático son insuficientes y opina que la química puede aportar soluciones a problemáticas concretas.

Omar Yaghi: “Las técnicas que capturan el CO2 consumen mucha energía”
Omar Yagui

Profesor de Química de la Universidad de California, en Berkeley (EE UU) y recientemente ganador del Premio BBVA Fronteras del Conocimiento en la categoría de ciencias básicas, por el desarrollo de materiales capaces de capturar y almacenar dióxido de carbono (CO2) y extraer agua.
