    El límite material de la sustancia química
    Dianoia 66 (86): 51-78. 2021.
    Resumen La química tal y como la conocemos hoy es un sistema de prácticas científicas estables y experimentales que se enseñan de la misma manera en la mayoría de los países. Es heredera de una multitud de oficios que coinciden en el objetivo de transformar y crear nuevas sustancias. Aquí se discute el límite material de la sustancia química mediante el ejemplo del carbono, y en particular del experimento de difracción del C60. Con ello se intentará precisar el concepto de sustancia química y su…Read more

    A layered interpretation of the history of chemistry is discussed through chemical revolutions. A chemical revolution mainly by emplacement, instead of replacement, procedures were identified by: a radical reinterpretation of existing thought recognized by contemporaries themselves, which means the appearance of new concepts and the arrival of new theories; the use of new instruments changed the way in which its practitioners looked and worked in the world and through exemplars, new entities wer…Read more

    The fifth chemical revolution: 1973–1999
    Foundations of Chemistry 19 (2): 157-179. 2017.
    A new chronology is introduced to address the history of chemistry, with educational purposes, particularly for the end of the twentieth century and here identified as the fifth chemical revolution. Each revolution are considered in terms of the Kuhnian notion of ‘exemplar,’ rather than ‘paradigm.’ This approach enables the incorporation of instruments, as well as concepts and the rise of new subdisciplines into the revolutionary process and provides a more adequate representation of such period…Read more

    Science is one of the main attributes of the contemporary world and, more than any other human activity, characterizes the current period from previous centuries. Great advances in the field of science and technology deeply influence natural and social processes. There has been a worldwide recognition of the role of science in modern societies, along with an urgent need to move towards more and better scientific education, particularly in developing countries. It becomes fundamental to modify th…Read more

    Besides the presentation and conclusions, the chapter is divided into two equally important sections. The first one describes the modern development of atomic and molecular structure, emphasising some of the philosophical problems that have been taken, and those that have to be faced in its understanding. The second discusses the alternative conceptions and difficulties of students of different educational levels and also the different approaches to its historical or philosophical teaching. Fina…Read more

    Technochemistry: One of the chemists' ways of knowing (review)
    Foundations of Chemistry 15 (2): 157-170. 2013.
    In this article, from the characterization of technoscience of the English historian J. Pickstone and the recognition of the importance of models and modelling in research and teaching of chemistry, the term technochemistry is introduced as a way of chemical knowledge. With the above new possibilities, rethinking the chemistry curriculum is opened
