![]() Sin esta autocrítica será inviable un uso sensato de las técnicas y tecnologías, con su enorme potencial para la mejora de la condición humana, al tiempo que evitamos –si aún fuese posible– la deriva exterminista, nihilista y suicida de la civilización industrial. hemos de resistir frente a esas ilusiones destructivas, lo cual significa: la racionalidad técnica tiene que realizar su propia crítica de la razón utópica (en el sentido de Franz Hinkelammert). En definitiva, ser dioses –dioses pensados como Superingenieros Inmortales. Se piensa que la ciencia y la técnica pueden permitir a la mente humana escapar de las limitaciones que caracterizan su estado natural, liberándose del anclaje a la materia biológica y escapando de la condición humana. Hoy, la mentalidad dominante en occidente –que tiende a convertirse en una cosmovisión universal– tiene mucho en común con las creencias de. La tentación con que seduce el utopismo tecnológico, desde los mismos orígenes de la Modernidad occidental –recordemos la isla de Bensalem de Francis Bacon en su New Atlantis–, es el completo dominio sobre la naturaleza (que incluiría la inmortalidad humana). ![]() The article concludes by detaching the potential transformation and the risks wrapped in the use from nanotechnologies and the success of national innovation systems in selected countries. The methodology of the article is descriptive and uses an evolutionary theoretical skeleton to analyze the evolution of the nanoscience and of the nanotechnologies and the emergency of a technological new paradigm. the transformations induced by nanosciences and nanotechnologies in the knowledge and the patents bases due to national innovation systems in selected countries. The article realizes a literature's review to delineate the state of the art and analyzes. The nanotechnology and the nanoscience can promote a revolution in various scientific and productive fields, generating a new wave of creative destruction, since the proprieties of the substances and products in the nanometric and molecular scale differ if compared to their proprieties in traditional scale. It is suggested that Cs (I) and Sr (II) can be fixed on carboxyl functional groups and Cs (I), possibly, in insignificant amounts on phenolic hydroxyls of all four studied organic sorbents. ![]() The sorption of Cs (I) is highest on brown coal and lesser for high-moor peat, shungite and hard coal. ![]() Sr(II) sorption decreases in the following order: high-moor peat> brown coal> shungite> hard coal. As a result of the conducted research, it can be concluded that Sr (II) showed a higher sorption per unit specific surface area than Cs (I) in the studied range of concentrations and pH values. XRD, XRF, SEM and BET adsorption methods were used for assaying. A detailed description of their mineral composition, cation exchange capacity, buffering capacity and elemental composition of sorbents is provided. In order to determine the influence of the physical properties and the quantity of functional groups of the organic sorbents on sorption, experiments were carried out on organic materials of varying degrees of metamorphism: high-moor peat, hard and brown coals and shungite. ![]() The present study examines the sorption of Сs (I) and Sr (II) on organic sorbents in the pH range from 2 to 10, as well as the mechanisms of their binding. ![]()
