Con frecuencia, a la tecnología le lleva muchos años abrirse paso del laboratorio a los hogares de la gente común. Sin embargo, en el caso de la tecnología Quantum Dot con la que cuentan los televisores Samsung QLED, sólo transcurrieron cerca de 30 años para que esto sucediera. Parece mucho tiempo, pero es realmente poco si no conocemos los antecedentes históricos.
En realidad, la historia de los puntos cuánticos no es tan breve. Se remonta a muchos años atrás, hasta la creación de las ventanas de vitrales — en el siglo I d.C. Es así que los humanos hemos estado aprovechando el poder de las nanopartículas — elemento central de los puntos cuánticos que acciona las imágenes sorprendentes del televisor QLED — durante mucho, pero mucho tiempo. Retrocedamos y veamos uno de los ejemplos más antiguos: las majestuosas ventanas de vitrales que datan del siglo I d.C.
¿Cómo funcionan los vitrales?
Los vitrales han existido por más de 1000 años— ¡definitivamente mucho más que el televisor QLED! En especial, los vitrales se usaban como medio de expresión artística, que se encontraba comúnmente en las iglesias europeas, durante la Edad Media. Los artistas medievales que incursionaban en la alquimia mezclaban el cloruro de oro y plata con vidrio fundido, para crear tintes rojos y amarillos que brillaban espectacularmente con la luz del sol. Cuando la luz tocaba el vitral, las nanopartículas de cloruro actuaban como puntos cuánticos, reflejando una magnífica variedad de luces rojas y amarillas en esa zona del espectro de colores.
Entonces, ¿qué tiene que ver eso con el televisor QLED?
Bueno, las creaciones sensacionales de vitrales que se encuentran en las catedrales europeas, son uno de los primeros ejemplos de la aplicación de nanopartículas similares a los puntos cuánticos por artistas humanos. Los óxidos y cloruros metálicos que se encuentran en los vitrales reaccionan con la luz de una manera similar a la de los puntos cuánticos. 1 Dichas nanopartículas tomaron un papel fundamental en la creación del fascinante efecto de estas obras clásicas de arte. Y las mismas nanopartículas — aunque mejoradas — se encuentran en las pantallas de los televisores QLED, brindando las imágenes vívidas con las que la nueva línea de Samsung está siendo reconocida.
Cómo trabajan los puntos cuánticos y cuáles son sus efectos
Mucho después de que los artistas alquimistas medievales descubrieran el método de incorporar químicamente cloruros en el vidrio, los científicos modernos empezaron a descubrir un fenómeno relacionado, casi por accidente. Al fracturar materiales con propiedades semiconductoras en partículas nanométricas — sólo ligeramente mayores que las moléculas de agua — se descubrieron otras propiedades interesantes. El tamaño ajustado de las partículas afecta el color de la emisión de luz, como resultado del cambio en la energía de banda prohibida. De este modo, al controlar el tamaño de un punto cuántico con incrementos diminutos, el espectro de colores puede expresarse en forma más plena y pura.
¿No es sorprendente que el proceso para controlar las nanopartículas para que produzcan colores asombrosos se haya refinado tanto, que ahora podamos encontrar puntos cuánticos en un televisor moderno? Hoy podemos apreciar imágenes impresionantes gracias a los puntos cuánticos de los televisores QLED, tanto como en las increíbles luces de los paneles de vitrales en las catedrales más importantes del mundo.

The leader of the Martial Alliance has always been represented by Meng Changfeng, so instead of leaving this matter to be digested within his own sect, it is better to leave it to others to worry about.Outside the car, the middle aged man s tone was much more serious I don t know what kind of person he is, but I know that he is the person chosen by the old dragon master himself.
When Liang Rong came to the door, he asked Miao Jin to make Qin Shufang and Tang Kexin fall asleep.You

But if we let her know how powerful we are, wouldn t it be better to stand up when she is in the most difficult time, so that she has to choose to rely on us Lin Waner s words naturally make sense, but Ye Ru The wind did not let go.
Zhizhi Jixiang stood at the entrance of the gorge that required sideways passage and shouted at Jiang Yuebai.The other things are not as powerful as her own spells, so she can only Used to disturb the enemy.
Xie Jingshan sat down, I was just about to tell you, something really big happened, you know that Fang is dead How many people are there Except for those few Nascent Souls, all the direct and concubine members of the Fang family who had the Juman bloodline were all dead, and the Fang family chief and great elder were also
Xie Jingshan made a gesture of wiping his neck
Not only the Fang family, but also several elite disciples from other families who were guarding under the icicles were killed
Outside the house, Xie Guihong, who was lying down in the corner to eavesdrop, sighed quietly and turned around to see Ding Lanzhi.
Qi An s body was fragile, so Jiang Yuebai could only try his best to dodge, not daring to face him head on.Xie Jingshan covered his chest and stepped back, with a look of disbelief on his face, You
are not talking
about the ancient language of the Dragon Clan Yes, Anan has only learned it for half a month and has already mastered most of it.
The mirror was originally water. Attributes are like a bottomless pit.Jiang Yuebai sat by the cold pool and yawned. After trying the sixty four changes of the formation, they all worked normally.
Take one out, and the wood does have an unusual aura.Once in the air, he would always have uncontrollable dizziness and vomiting.
At this moment, the water under Jiang Yuebai s feet suddenly began to spin rapidly, Who Sells CBD Gummies for Sleep: Best Options and Reviews

The disadvantage is of course that if this inventory is not enough, the last level of Dragon God Transformation still requires dragon souls, and it is almost impossible to find Zhulong later.Jiang Yuebai s sleeping body was re infused with life, and his black hair gradually faded away, like countless extremely thin white vines, blooming with small white flowers.
Live, those aliens are limited by their bodies and bloodline, and they have basically reached the ultimate level after practicing to the foundation building stage, and almost none can reach the golden elixir stage.His body was shining with aura, and he looked like Vigorvita CBD Gummies Reviews: A Comprehensive Analysis of Benefits and Legitimacy (atKvR)
he had just broken through to the ninth level of Qi training.

Storage bags and storage magic weapons are on the same level.The scene in front of him flew by quickly. Xie Jingshan practiced his sword every day, fed him luck, went out to play with the three legged golden bird, and came back to practice his sword after playing.
Too many people. I don t know the details. I only know that the three of them got along well with each other and often went out together.Jiang Yuebai worked hard and patrolled the surrounding area.

They also learned that two Jindan generals were going to fight.No matter how sincere the Feihua Sect was, it was at least beneficial to the He family.
Zhuo Wuhua was hardened and gritted his teeth. Without making a sound, he cursed You are a sinister and vicious little devil.Mr. Chu saw something, but he didn t rush out. He just looked back in the direction of Ye Ling in confusion.
Could it be that Baoguang appeared in the Thunder Pond Did the thunder pool absorb the thunder calamity Go back and report to the sect master If it s too late, I m afraid the Golden Crow tribe will get it Ahem, the He Immortal Cultivation Family and Feihua Clan are fighting endlessly these days, and none of them can spare any effort to deal with the Golden Crow Tribe on Dongsang Island.

At this time, the Ice Butterfly, the Red Fire Green tailed Leopard and the Ninth Level Giant Whale, together with the Immortal Sect monks stationed at Chaoyang Peak, chased and killed the remnants of the patrolling Yasha The old catfish demon and the green and black fish demon also turned back and reported to Ye Ling Lord The golden armored yaksha saw that we were in large numbers and fled deep into the East Sea.
For me, it s more important to save my life Ye Ling was thinking secretly.When things got serious, he even broke the rules set by the Lord of Qingzhu City.
His consciousness was destroyed and his soul was hurt.It s just that the casting time is too long. When facing the enemy, the sword and sword shadow will come in an instant.
