Analysis of social perception on nanoscience and nanotechnology state of the art and implications is presented as a result of a wide survey carried out at Universidad Autónoma Metropolitana Iztapalapa, Universidad de las Américas Puebla, Escuela Superior de Ingeniería Mecánica y Eléctrica Culhuacán, Escuela Superior de Comercio y Administración Tepepan and the Centro de Investigación y de Estudios Avanzados, north and south units. Four hundred and 64 interviews were applied to students and teachers. Data follows the survey scheme used on a previous study for UNAM’s Ciudad Universitaria campus social perception that has been published on volume 4, No. 1 of this journal. Some small modifications have been done in order to fit the survey to all institutes and universities contexts. We conclude by supporting the effortand interest of promoting responsible science and technology in our country. Studies like this have the purpose of detecting the degree of (dis)interest on science and technology of the high education level community and the ways its development is perceived. The goal: Contributing with an analysis considered useful for any attempt to revert disinformation.

Today, existing power plants based on coal present in the world emit about 2 billion tons of CO2 per year. Because of its fundamental engineering and economic advantages in competing separation technologies, membrane operations are being explored for the separation of CO2 and other exhaust emissions of power plants based on fossil fuels. [1] The zeolite imidazolate framework (ZIFs) are novel microporous materials with different structures and pore sizes and large surface areas. Membranes of these materials have great potential for the separation of gas mixtures energy and environmental interest. [2-4] This paper reports the synthesis and characterization of two potentially useful membrane separation of CO2 from the compound known as ZIF-8 and an amendment thereto using a mixture of metals (Zn and Co). This modification is expected to modulate the interaction enthalpy and thereby turn the selectivity of the membrane as a result of the involvement of two types of metals in the molecular lattice.
