This eBook teaches adhesive and sealant formulation in two steps. Each section first describes the application and chemical basis of the type of adhesive or sealant concerned. This is followed by formulation advice and - if possible - an analysis of existing recipes. This analysis includes a calculation of the important characteristic values of the formulations. All calculations based on recipes and formulations are worked through step by step and should therefore be intelligible to beginners, too.

Fruto de su dilatada experiencia como autor W.R. Peterson ha escrito esta obra con la intención de que sea el primer contacto de cualquier estudiante de ciencia o tecnología con la formulación y la nomenclatura de las sustancias quimicas. La obra mantiene las caracteristicas pedagogicas y el estilo que han convertido los libros de formulacion y nomenclatura escritos por el autor en textos de estudio y referencia en multitud de centros docentes y universidades hispano-americanas.

Fundamentos de tecnología química es un libro de texto y de enseñanza al servicio de las jóvenes generaciones que desean adquirir una formación profesional y especialmente para los que buscan una cualificacion en las actividades propias de las fabricas quimicas.

El presente material fue elaborado como un recurso de apoyo para el aprendizaje de la Toxicología en la carrera de Química Farmacéutico Biológica de la Facultad de Química, UNAM. Está constituido por diez capitulos que abarcan casi la totalidad del programa oficial de esta asignatura. El primer capitulo es una introduccion que comprende aspectos historicos y la clasificacion de agentes toxicos. El segundo y tercero incluyen las bases para la comprension de las tres etapas de la accion toxica: exposicion, toxocinetica y toxodinamica. El cuarto apartado esta constituido por los conceptos, definiciones y ejemplificaciones de las reacciones de biotransformacion y su relacion con la bioactivacion de moleculas organicas. Del quinto al octavo capitulos se presentan los mecanismos de accion de mayor recurrencia entre los agentes toxicologicos: estres oxidante, mutagenesis, carcinogenesis, teratogenesis. Finalmente, los dos restantes, fueron elaborados como topicos particulares para un grupo determinado de sustancias (metales y farmacos).

LO QUE HOY ENTENDEMOS POR QUÍMICA SE DEBE EN GRAN MEDIDA A LOS DESCUBRIMIENTOS DE ROBERT BOYLE, ANTOINE LAVOISIER Y MARIE CURIE.Una historia divulgativa y rigurosa, que recorre tres siglos de avances en la historia de la quimica, a traves de la vida y la obra de tres figuras eminentes. Las dos transformaciones mas profundas de la historia de la ciencia fueron la de la Astrologia en Astronomia y la de la Alquimia en Quimica. La primera nos llevo al universo a gran escala y la segunda a lo mas intimo de la materia. Robert Boyle (1627-1691) fue un excelente alquimista, pero su espiritu critico lo llevo a convertirse en el primer quimico moderno. En el siglo siguiente, los trabajos de Antoine Lavoisier (1743-1794) supusieron una transformacion radical en esta nueva rama de la ciencia, que paso de un enfoque cualitativo a otro mas cuantitativo. La ultima protagonista de este libro es la unica persona que ha obtenido dos premios Nobel: Marie Curie, cuyo descubrimiento de la radiactividad encauzo la ciencia hacia derroteros insospechados. Las vidas de estos tres genios son tan apasionantes como sus logros cientificos.

En las páginas de este libro, el lector hallará los fundamentos de todo cuanto debe saber para crear profesionalmente un perfume: desde explicaciones detalladas sobre la percepción, los gustos de las distintas culturas y las materias olorosas clasificadas por familias hasta los metodos de extraccion mas habituales y, con ellos, el proceso de creacion propiamente dicho.

In "Heads of Lectures on a Course of Experimental Philosophy: Particularly Including Chemistry," Joseph Priestley presents a pioneering exploration of the scientific principles underpinning chemistry and the natural sciences. This foundational work, employing a didactic pedagogical style, dissects complex topics into manageable segments, reflecting the Enlightenment tradition of empirical inquiry. PriestleyAos synthesis of experimental observation and philosophical reasoning situates the lectures within the broader context of 18th-century science, a time ripe with discoveries that challenged conventional wisdom and expanded the understanding of matter and its interactions. Joseph Priestley, a polymath with a background in theology and a fervent interest in natural philosophy, was influenced by contemporaries such as Antoine Lavoisier and Isaac Newton. His commitment to empirical study and innovative experimentation, including his work on gases and electricity, informed his lectures and illuminated his pedagogical approach. Priestleys own scientific endeavors culminated in this work, which aimed to equip students and fellow scientists with a clear understanding of experimental methods and chemical principles. This book is highly recommended for anyone keen on understanding the historical evolution of chemistry and the scientific method. It serves as an invaluable resource for scholars and students alike, providing insights into not only the scientific concepts of the time but also the intellectual climate that fostered such revolutionary ideas.
