Chemists create organic molecules in a rainbow of colors that could be useful as organic light-emitting diodes

Chains of fused carbon-containing rings have unique optoelectronic properties that make them useful as semiconductors. These chains, known as acenes, can also be tuned to emit different colors of light, which makes them good candidates for use in organic light-emitting diodes. The color of light emitted by an acene is determined by its length, but as the molecules become longer, they also become less stable, which has hindered their widespread use in light-emitting applications. MIT chemists have now come up with a way to make these molecules more stable, allowing them to synthesize acenes of varying lengths. Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.

schottky diode smd - PCB Antenna

A diode is a two-terminal electronic component that allows current to flow in one direction while blocking it in the other direction. It is a semiconductor device made up of a p-type material and an n-type material, which are joined together to form a p-n junction.

Diodes are commonly used in electronic circuits for a variety of purposes, such as rectification (converting AC to DC), voltage regulation, and signal modulation. They are also used in power supply circuits, lighting circuits, and electronic displays.

thinking about the people in my poll who said in finnish, their native language, they say LED as a word and that word is ledi... I love that so so much, ledi... cute 10/10

#elias.txt #perhaps the only correct way to say LED actually #people who say Light Emitting Diode will always have a special place in my heart also

I miss the atmosphere of vanilla rain world.

#look i like the rain world fandom slightly sometimes. but it does not understand or depict the atmosphere of vanilla #the rat in a subway theme. the mystery of everything.#Literally no information can be truly taken for granted. but that doesn't matter because you dont need that information #Does tge slugcat need to know whether the lizards glow through bioluminescence or with light emitting diodes?#Does it need to know the nature of the civilization that created the ruins it now calls home?#No. You are tiny beast exploring a mysterious environment you will never fully understand the nature of.#boiled electronics #Should i add my tags to the post someone tellvme

Apple Not Going to Design Displays for Its Watches - Technology Org

New Post has been published on https://thedigitalinsider.com/apple-not-going-to-design-displays-for-its-watches-technology-org/

Apple Not Going to Design Displays for Its Watches - Technology Org

Apple has considered making displays for its own smartwatches – but only briefly, and with no lasting outcome.

According to Bloomberg News, Apple has decided to abandon its efforts to internally design and create smartwatch displays. The decision to halt the project was reportedly driven by the substantial expenses and technical intricacies involved.

Consequently, the company is said to be restructuring the teams responsible for display engineering and is reducing its workforce by eliminating several dozen positions in both the United States and Asia.

The decision to halt the display project coincided with Apple’s move to discontinue its efforts in developing a self-driving car.

The display project was part of Apple’s broader strategy to increase its in-house technology development. While the second-most valuable venture already tailors displays in its products, these displays largely rely on designs from partners such as LG Display Co. and Samsung SDI Co. By internalizing more of the display manufacturing process, Apple aimed to gain a competitive advantage over its rivals.

MicroLED technology, composed of millions of microscopic light-emitting diodes, held particular promise for Apple. It consumes less power, delivers more accurate color reproduction, and enables thinner devices.

The initiative began approximately seven years ago within Apple’s hardware engineering division. Codenamed T159, the project migrated to the company’s hardware technologies division several years ago.

To support its microLED efforts, Apple established a screen manufacturing facility in Santa Clara, California, near its Cupertino headquarters.

Initially, the developer aimed to integrate microLED screens into the Apple Watch as early as 2020. However, multiple delays pushed the timeline to 2024, and subsequently, to 2025 and beyond, mirroring the setbacks faced in Apple’s electric car project. Despite Apple’s ownership of the microLED design and manufacturing process, challenges in mass production persisted. LED transfers, a crucial step in the manufacturing process, posed significant hurdles.

Presently, the company views OLED as the optimal solution for its smartwatches. However, microLED remains a future consideration for other projects. The company continues to explore potential suppliers and processes that could facilitate the integration of microLED technology into its devices, although this is unlikely to occur in the near term.

Scientists create process to upcycle plastics into energy-storage liquids using light-emitting diodes

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have created a process that can upcycle most plastics into chemical ingredients useful for energy storage, using light-emitting diodes (LEDs) and a commercially available catalyst, all at room temperature. The new process is very energy-efficient and can be easily powered by renewable energy in the future, unlike other heat-driven recycling processes like pyrolysis. This innovation overcomes the current challenges in recycling plastics such as polypropylene (PP), polyethylene (PE) and polystyrene (PS), which are typically incinerated or discarded in landfills. Globally, only nine percent of plastics are recycled, and plastic pollution is growing at an alarming rate. The biggest challenge of recycling these plastics is their inert carbon-carbon bonds, which are very stable and thus require a significant amount of energy to break. This bond is also the reason why these plastics are resistant to many chemicals and have relatively high melting points.
