Resumen: La transformación química de dióxido de carbono en productos químicos de alto valor añadido o en materiales poliméricos de múltiples prestaciones mediante procesos catalíticos eficientes es uno de los mayores retos para las próximas décadas. En este trabajo se ofrece una visión global de la problemática y se invita al lector a considerar el dióxido de carbono como una fuente sostenible de carbono para la síntesis de carbonatos cíclicos y policarbonatos.
Palabras clave: Dióxido de Carbono, Catálisis, Química Sostenible, Carbonatos Cíclicos, Química Organometálica.
Abstract: Chemical fixation of carbon dioxide into high-value added chemical products or versatile polymeric materials through highly efficient catalytic processes is one of the biggest challenges for the next few decades. This work gives us a global vision for a better understanding of the problem, and proposes the use of carbon dioxide as sustainable carbon source for the synthesis of cyclic carbonates and polycarbonates.
Keywords: Carbon Dioxide, Catalysis, Sustainable Chemistry, Cyclic Carbonates, Organometallic Chemistry.
Aspects related with the collaboration of chemists belonging to Spanish institutions in publications of impact involving researchers from other Spanish institutions and foreign centres are discussed. The analysis covers the co-authorship index, and the characteristics of the collaboration between Spanish and foreign researchers. The relationship between collaborations and impact of publications shows that internationally co-authored papers had significantly higher impact factors.
Resumen: La Convención sobre la prohibición de las armas químicas obliga a los Estados Parte a destruir todos los arsenales que tuvieran bajo su control y jurisdicción. También afecta a las actividades de la industria química y de algunos de sus proveedores o clientes. Las Autoridades Nacionales de los Estados Parte deben adoptar las medidas necesarias para cumplir las obligaciones contraídas en virtud de dicha Convención. Este artículo describe algunas de las actividades que desarrolla la Autoridad Nacional Española para divulgar y hacer cumplir las obligaciones de la Convención.
Palabras clave: Convención Armas químicas, Industria química, Doble uso, No proliferación, Verificación, OPAQ.
Abstract: The Chemical Weapons Convention obliges States Party to destroy all stockpiles under their control and jurisdiction. It also impact on the activities of the chemical industry and some of its suppliers or customers. The National Authorities of States Parties shall adopt the necessary measures to implement its obligations under this Convention. This article describes some of the activities undertaken by the Spanish National Authority to publicize and enforce the obligations of the Convention.
Keywords: Chemical Weapons Convention, Chemical industry, Dual use, Non-proliferation, Verification, OPCW.
The history of the teaching of chemistry in Spain since the mid-nineteenth century to the present is summarized. To this end, educational laws and curricula, from the Moyano Law (1857) to the LOMCE (2013) are revised. The significant role played in the pedagogical renovation of science by institutions as the Institución Libre de Enseñanza and a number of teachers (Bargalló, Catalán, Comas, Estalella, Moles, Sensat…) is highlighted. Also discussed are some methodological proposals promoted from specialized publications, educational projects and the legislation itself.
Do you know what are the Smart Materials?. If unaware of their existence, you will not know how the performance of your vehicle are improved, you will not choose more fresh foods, or you will not choose the right material for climbing weekend. In this scientific dissemination article, the meaning of these also called stimulus response materials is described in a generalist way. Also some of their interesting applications as sensors in areas such as security, energy or volatile organic compounds detection are described.
