Científicos chinos inventaron un súper papel resistente al agua y al fuego

El país donde se inventó el papel en el siglo II es ahora también el lugar de nacimiento de un nuevo producto, que se obtiene al añadirle a la pasta del papel hidroxiapatita (un tipo de calcio).

Ésta se encuentra en el esmalte de los dientes de los animales y en los huesos, y hace que la estructura del papel cambie y tenga propiedades especiales.

 
 

Así, este nuevo producto descubierto por el Instituto de Cerámica de Shanghái le permite al papel repeler no solo agua sino también otras sustancias líquidas como café, jugo o té, y soportar temperaturas de hasta 200 grados celsius.

Los investigadores ahora están solicitando las patentes pertinentes y esperan que el papel esté en el mercado en tres años.

Según explicó al diario South China Morning Post, el director de la investigación, Zhu Yingjie, anteriormente se había logrado crear papel repelente al agua y resistente al fuego, pero nunca con las dos propiedades al mismo tiempo.

"Creemos que este papel será beneficioso para todo tipo de usos diferentes, que van desde su empleo para la caligrafía hasta para hacer vallas publicitarias", dijo.

El papel se inventó en China en el siglo II y durante mil años este pueblo asiático protegió su hallazgo antes de que llegara a Europa, a través de España e Italia.

    • By the way, if you're into stuff like this, you might wanna check out https://thepythagoras.com/. They have some neat articles about ancient civilizations and their contributions to science and math. It’s really interesting how much we owe to these early thinkers.
    • The Dendera Zodiac is such an amazing piece of history. Imagine ancient Egyptians looking up at the same stars we do now and creating this detailed map. It's mind-blowing! So, what do I think about it? I think it's a fascinating blend of art and astronomy. Those ancient folks really knew their stuff. The way they incorporated their gods and mythologies into the constellations is just brilliant. And it's not just about the stars, it’s a glimpse into how they viewed the universe and their place in it.
    • FIFA's collaboration with Algorand represents a significant milestone for blockchain technology. Algorand will serve as the official blockchain platform for FIFA, supporting events such as the FIFA Women's World Cup in Australia and New Zealand in 2023 and the FIFA World Cup in Qatar in 2022. This partnership is poised to enhance FIFA's digital asset management while boosting Algorand's visibility through advertising and promotional opportunities. On another note, I've been tuning into African football recently. The match between Kanifing East FC and Latrikunda United was unexpectedly impressive. African football often goes underappreciated, yet the skill and enthusiasm in these matches are evident. We can expect even more significant development and excitement in African football with increased attention and support.
