Quantum dot Puns

Did you miss the boat by not taking the huge opportunity to buy into DOT and/or KSM early?

​

KSM has gone from a market cap of around 6 million in January 2020 to now being worth 3.7 billion even before their main net is live. That's over 600x in roughly 12 months.

​

The reason for these gains is that most other layer 1 protocols have bottle necks and sacrifice certain parameters for others. Whereas ParaChains are decentralized, highly scalable, secure, forkless & interoperable.

​

Finally, a second chance with CellFrame / $CELL. Launched only one week ago and is the ONLY competitor using comparable technology. This project legitimately feels like a second chance at getting into KSM and DOT at a micro cap level.

​

CellFrame brief overview:

​

- CellFrame will have CellChains and is the only blockchain with comparable tech to what $DOT / $KSM are doing with ParaChains.

​

- In development for over 4 years with an extremely active Github.

​

- 100-1000x lower market cap than KSM & DOT.

​

- CellFrame will have CellChain auctions, live in June 2021 with only 50 available & the lease will be for 3 years.

​

- Designed to build & manage quantum-safe blockchain solutions with Cellframe SDK.

​

- Visible and highly experienced team backed by some of the biggest VCs in the industry.

​

Detailed overview:

​

CellFrame's built with 2 layers. One is the private shard with it's own consensus & token $CELL.

​

The ledger on the private shard will be the same across all other blockchains. Each will have their own wallet but they can communicate with each other.

​

This allows transfers or trading of tokens from Ethereum to Polygon or BSC ETC, as long its compatible. Meaning just like KSM and DOT the CellFrame ecosystem and code base is decentralized, highly scalable, secure, forkless & interoperable.

​

Cross chain bridges for Substrate & Bitcoin are already planned for Q2 and EVM based contracts in Q4 along with their main net.

​

The second layer is for sub shards which are similar to DOT / KSM parachains. This allows for launching customizable subchains and tokens. There will be 50 CellChain slots in total which will be auctioned starting in June this year.

​

This will create huge demand for the native CELL token as projects or businesses will need to bid for these slots and then this supply will be locked for 3 years.

​

With CellChain auctions going live in June and a fully fledged marketing campaign due to ki

I'm looking at getting either one of these, but just wondering if Quantum Dot is worth it for $200 more (AUD$569 as apposed to AUD$769)? I couldn't really find any comprehensive reviews on the non QD version, so I'm also concerned it has more cut corners compared to the QD version.

I currently have a 1080p 144Hz monitor, but am looking at getting a new 1440p monitor as I recently upgraded to a 3070. I do quite a lot of gaming (singleplayer more so than multiplayer, but I still play MP games regularly). So I'm generally just wondering if anyone has first hand experience with both of these, and whether or not the extra $200 is worth it for quantum dot?

The study of nanocrystal self-assembly into superlattices or superstructures is of great significance in nanoscience. Carbon nitride quantum dots (CNQDs), being a promising new group of nanomaterials, however, have hardly been explored in their self-organizing behavior. Here we report of a unique irradiation-triggered self-assembly and recrystallization phenomenon of crystalline CNQDs (c-CNQDs) terminated by abundant oxygen-containing groups. Unlike the conventional self-assembly of nanocrystals into ordered superstructures, the photoinduced self-assembly of c-CNQDs resembles a “click reaction” process of macromolecules, in which the activated –OH and –NH 2 functional groups along the perimeters initiate cross-linking of adjacent QDs through a photocatalytic effect. Our findings unveil fundamental physiochemical features of CNQDs and open up new possibilities of manipulating carbon nitride nanomaterials via controlled assembly. Prospects for potential applications are discussed as well.

Stable and efficient CsPbI3 perovskite light-emitting diodes (PLEDs) are demonstrated by resurfacing perovskite with the aid of inorganic ligands (KI). The resurfaced perovskites show a 7× higher phase stability and higher thermal conductivity than in films with organic ligands. The PLEDs exhibit a record-high external quantum efficiency (EQE) of ≈23 % and a 100-fold improvement in the operating stability compared to previous EQE devices.

Abstract

The all-inorganic nature of CsPbI3 perovskites allows to enhance stability in perovskite devices. Research efforts have led to improved stability of the black phase in CsPbI3 films; however, these strategies—including strain and doping—are based on organic-ligand-capped perovskites, which prevent perovskites from forming the close-packed quantum dot (QD) solids necessary to achieve high charge and thermal transport. We developed an inorganic ligand exchange that leads to CsPbI3 QD films with superior phase stability and increased thermal transport. The atomic-ligand-exchanged QD films, once mechanically coupled, exhibit improved phase stability, and we link this to distributing strain across the film. Operando measurements of the temperature of the LEDs indicate that KI-exchanged QD films exhibit increased thermal transport compared to controls that rely on organic ligands. The LEDs exhibit a maximum EQE of 23 % with an electroluminescence emission centered at 640 nm (FWHM: ≈31 nm). These red LEDs provide an operating half-lifetime of 10 h (luminance of 200 cd m−2) and an operating stability that is 6× higher than that of control devices.
