2014 - Año Internacional de la Cristalografía



El Año Internacional de la Cristalografía

El mundo de los cristales es, como todo el universo, bello, y sin duda alguna, es de una belleza que fácilmente se entiende, que atrae nuestra atención y que entra por nuestros ojos. Esta belleza atrajo a un número de curiosos e investigadores de todos los tiempos, cautivados por la contemplación de minerales cristalizados. Esta fascinación les llevó a tratar de comprender qué tipo de orden es necesario para que un cristal tenga existencia; de este estudio nació en el transcurso de los tiempos una ciencia basada en elestudio del orden y de la simetría, la Cristalografía, ciencia que se dedica al estudio de las estructuras cristalinas y las propiedades, a veces mágicas de cristales.
La Asamblea General de Naciones Unidas proclamó 2014 Año Internacional de la Cristalografía , IYCr2014, conmemorando de esta manera, no solo el centenario de la difracción de rayos X como herramienta para el estudio de la materia cristalina, sino también el 400 aniversario de la observación de simetría en los cristales de hielo (Kepler,1611), que dio comienzo al estudio profundo de la simetría en los materiales. Entre otros puntos, la resolución reconoce que la comprensión material de nuestro mundo se debe en particular a esta ciencia y subraya que la enseñanza y aplicación de la misma es fundamental para hacer frente a múltiples desafíos esenciales para el desarrollo de la humanidad

La Asamblea General de las Naciones Unidas decide proclamar 2014 Año Internacional de la Cristalografía.
El 3 de julio de 2012 la Asamblea General de las Naciones Unidas en la Resolución 66/284 decide proclamar 2014 Año Internacional de la Cristalografía.1
Destacando que la educación en materia de cristalografía y su aplicación son fundamentales para hacer frente a desafíos como las enfermedades y los problemas ambientales, ya que determinan las estructuras proteicas y de moléculas pequeñas utilizadas en el diseño de medicamentos esenciales para la medicina y la salud pública, así como las soluciones para la contaminación de las plantas y del suelo.
La Asamblea General decide declarar el 2014 Año Internacional de la Cristalografía.
 
20 de enero, 2014 — La ONU lanzó hoy el Año Internacional de la Cristalografía, con el objetivo de generar más conciencia en torno al potencial de esta disciplina científica que ha permitido descubrir la estructura del ADN, entre otros logros.
La proclamación de este año tuvo lugar durante un evento celebrado hoy en la sede de la UNESCO en París.
La UNESCO será precisamente la encargada de coordinar los eventos relativos a esta conmemoración y de resaltar su importancia en la agenda de desarrollo post-2015 para abordar el hambre, la disponibilidad de agua potable, la atención a la salud, la energía sostenible y la recuperación del medio ambiente, entre otros desafíos.
Ese Organismo destacó las numerosas aplicaciones que tiene la cristalografía en la vida cotidiana y su uso en el sector industrial para el desarrollo de nuevos productos.
También se emplea en la agronomía, la aeronáutica, los automóviles, cosméticos, fármacos y computadoras.
Además de facilitar el descubrimiento de la estructura del ADN, la cristalografía permite fabricar las memorias de las computadoras y ayuda a los científicos a diseñar potentes medicamentos.

Como parte de las actividades para generar más entendimiento sobre esa ciencia, la UNESCO ha puesto en marcha un concurso de crecimiento de cristales, dirigido a las escuelas secundarias en todo el mundo.

Bienvenido al maravilloso mundo de los cristales. 1:24



 Capitulo 3 Cristales Gigantes
 Los griegos llamaron cristal al cuarzo, κρνσταλλοσ (cristallos = frío + goteo), es decir, carámbanos de extraordinaria dureza y muy fríos. Pero la formación de cristales no es exclusiva de los minerales, y los encontramos también (aunque no necesariamente de modo natural) en los compuestos llamados orgánicos, e incluso en los ácidos nucléicos, en las proteínas, en los virus...
El estado cristalino de la materia es el de mayor orden, es decir, es aquel en donde las correlaciones internas son mayores y a mayor rango de distancias. Y esto se refleja en sus propiedades que son anisotrópicas y discontínuas. Suelen aparecer como entidades puras, homogéneas y con formas geométricas definidas (hábitos) cuando están bien formados. Sin embargo, aquí una vez más, "el hábito no hace al monje" y su morfología externa no es suficiente para evaluar la denominada cristalinidad de un material.
