Curiously, all the technological devices that we enjoy today, from the television to the LEDs that illuminate our houses, through our mobile phones use the so-called "rare earths", chemical elements so called because they rarely appear in pure form and some of them have some limited reservations worldwide.
Curiosamente todos los aparatos tecnológicos que disfrutamos hoy día, desde el televisor hasta los led que iluminan nuestras casas, pasando por nuestros teléfonos móviles utilizan las llamadas "Tierras raras", elementos químicos llamados así porque raramente aparecen en forma pura y algunas de ellas tienen unas reservas limitadas en todo el mundo.
In addition, many of these materials abound in areas with dubious governments and are the cause of the greatest atrocities perpetrated against human beings, in these normally underdeveloped countries the ownership of these resources makes them live in a permanent war.
Como añadidura muchos de estos materiales abundan en zonas con gobiernos de dudosa catadura y son causa de las mayores atrocidades perpetradas contra el ser humano, en estos países normalmente subdesarrollados la propiedad de estos recursos hacen que vivan en una guerra permanente.

One of these elements is indium, one of the nine rarest elements on Earth, which in the form of indium tin oxide (ITO), is used in the manufacture of organic light emitters, the so-called OLEDs that you have surely heard about and that are part of all the touch screens that we use on our devices, among other things.
Uno de estos elementos es el indio, uno de los nueve elementos más escasos de la Tierra, que en forma de óxido de indio y estaño (ITO), se utiliza en la fabricación de emisores de luz orgánicos, los llamados OLED que seguramente habréis oido nombrar y que forman parte entre otras cosas de todas las pantallas táctiles que utilizamos en nuestros dispositivos.
According to recent scientific research, this scarce element may be replaced by graphene, a single-layer material made up of carbon atoms that is much more abundant on Earth and therefore much more sustainable than indium, as well as behaving identically to indium in the manufacture of touch screens and other devices.
Según una reciente investigación científica este escaso elemento podrá ser sustituido por el grafeno, un material de una sola capa formada por átomos de carbono que es mucho más abundante en la Tierra y por tanto mucho más sostenible que el indio además de comportarse de modo idéntico al indio en la fabricación de pantallas táctiles y otros dispositivos.

Despite all the research carried out by various companies on the subject, the problem that graphene currently has is that it is difficult to produce on a large scale, but the developers of this research claim that they have discovered a system for producing graphene on surfaces large enough to be used in electronic devices.
A pesar de todas la investigaciones llevadas a cabo por diversas compañías sobre el tema, el problema que tiene el grafeno actualmente es que es difícil de producir a gran escala pero los desarrolladores de esta investigación sostienen que han descubierto un sistema de producción de grafeno en superficies grandes que permita su uso en dispositivos electrónicos.
It seems that graphene, which receives so much praise from scientists, is beginning to have utility in our daily lives, there is no doubt that the manufacture of OLED with graphene not only eliminates the dependence on rare earths but that devices are supposed to they will go down in price and, more importantly, we will stop pestering the people of these affected countries.
Parece que el grafeno, que tantos elogios recibe por parte de los científicos, empieza a tener utilidad en nuestras vidas cotidianas, no cabe duda que la fabricación de OLED con grafeno no solo elimina la dependencia de las tierras raras sino que se supone que los dispositivos bajarán de precio y, lo que es más importante, dejaremos de importunar a los habitantes de estos países afectados.

Hola @mauromar, eso es genial el grafeno haría que avance la tecnología y de paso terminen esos problemas con los países afectados.

In total, these rare earths are made up of 17 chemical elements and they are essential in technological wars and also in armaments warfare, that's why the photo of those people who have the face of few friends and are armed to the teeth. The extraction of these minerals can be very expensive and also be contaminated from the radioactive point of view, it is good to know that Graphene is being used, considered the material of the future to replace these elements.
