Layer by layer: How simulations help manufacturing of modern displays

Modern materials must be recyclable and sustainable. Consumer electronics is no exception, with organic light-emitting diodes (OLEDs) taking over modern televisions and portable device displays. However, the development of suitable materials—from the synthesis of molecules to the production of display components—is very time-consuming. Scientists led by Denis Andrienko of the Max Planck Institute for Polymer Research and Falk May from Display Solutions at Merck have now developed a simulation method that could significantly speed up the development of new materials. High contrast and low power consumption are key features of innovative organic light-emitting diodes. OLEDs use thin films of organic molecules, i.e. carbon-containing molecules, to achieve these goals. Silicon-based materials currently used in other semiconductor devices, such as transistors, may also be replaced by organic counterparts.

A novel AI model could aid in the production of clean water

- By Nuadox Crew -

Around 2.2 billion people lack access to safe drinking water, and half of the global population faces severe water scarcity at some point each year.

To address these challenges, expensive solutions like sewer irrigation, rainwater reuse, and seawater desalination are used. However, centralized water systems struggle to quickly adapt to changes in demand, prompting interest in decentralized, electrochemical water production technologies.

Dr. Son Moon's team at the Korea Institute of Science and Technology (KIST), in collaboration with Professor Baek Sang-Soo’s team, developed an AI-based model using random forest techniques to accurately predict ion concentrations during electrochemical water treatment.

This model can monitor individual ions like Na+, K+, Ca2+, and Cl- and requires minimal computing resources compared to deep learning models.

The research offers potential improvements in national water quality management systems, helping to better monitor and manage water resources.

New organic molecule design can lead to long-lasting, durable OLEDs for displays

Scientists have developed a method to improve the stability and efficiency of organic light-emitting diodes (OLEDs), a technology used in smartphones, TVs, and other electronic displays. This advancement utilizes a unique type of molecule that has the potential to extend the lifespan of OLED devices significantly. The researchers present a novel way to design organic molecules that can maintain their stability and efficiency over time, even in high-stress conditions. The research is published in the journal Nature Communications. These new molecules represent a step change in our understanding of the very fundamental ideas about intramolecular charge transfer excited states. Conceptually, they break all our current ideas about these excited states and a totally new model linking molecular bonding patterns leading to the breaking of molecular pi-conjugation in the excited state has been developed in order to explain this new phenomena.

I need Dick to be completely delusional about Tim and consider him to be his nicest, most helpful, and most well-behaved sibling.

_____

Tim: I have never done anything wrong, ever, in my life.

Dick: I know this and I love you 🥰

Jason: ...Dick, are you fucking HIGH???

_____

Dick: You should consider trying to be more like Tim! He's always such a well-behaved angel ❤️

Tim: Thank you, Dick 😇

Damian:

________

Dick: Tim is very kind and always so polite! He would never be mean to someone on purpose! ❤️

Bruce, who is bullied by Tim an average of 4.5 times a day:

______

Dick: Tim is an absolute sweetheart!

Cass: ... I do not think that word means what you think it does.

_____

Duke, staring at a warehouse that he and Tim just 'accidentally' blew up: ... So how mad do you think Dick is going to be at us?

Tim: Don't worry, I got this.

Dick, landing next to them: Holy explosion, Red Robin! What happened here?!?

Tim: I don't know 😔. It was like this when we got here 🥺.

Duke, whispering: There is no way he's going to believe tha-

Dick: Oh no! Well, I'm just glad you two are safe!

Duke: ... Tim, I need you to teach me your ways.

Dick: hm? Did you say something, Duke?

________

Dick: I don't get it! Why does everyone think Tim is some kind of crazed feral gremlin?!?

Alfred: I believe that is because they have in fact met Master Tim.

Dick: What was that? 🙃

Alfred: ... 😮‍💨 Truly it is a mystery for the ages.

more of this shattered glass au!

here’s the high guard! elita, bee & orion together overpower D pretty easily and start frolicking through the city laying waste to everything, so they side with D to help him make a stand against his ex-gang and….they have a big fight or something??? i dont know!! but it’s cool to draw!!

Orion, bee, and elita still ultimately end up killing alpha trion through the power of friendship, but thats a comic for another time!!
