Diamond Aggregation [PDF]

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 2009
Internal diffusion-limited aggregation is a growth model based on random walk in Z^d. We study how the shape of the aggregate depends on the law of the underlying walk, focusing on a family of walks in Z^2 for which the limiting shape is a diamond ...

Direct demonstration of triplet excimer in purely organic room temperature phosphorescence through rational molecular design

open access: yesLight: Science & Applications, 2022
An ideal model containing eight phenothiazine 5,5-dioxide derivatives was established to clearly prove the formation of triplet excimer. Competition between monomer (T1) and excimer (T1*) based on π-π stacking is the origin for their changed RTP ...

Aggregate Productivity and Aggregate Technology [PDF]

open access: yesSSRN Electronic Journal, 1997
Aggregate productivity and aggregate technology are meaningful but distinct concepts. We show that a slightly-modified Solow productivity residual measures changes in economic welfare, even when productivity and technology differ because of distortions such as imperfect competition. We then present a general accounting framework that identifies several

Aggregation‐induced emission: Red and near‐infrared organic light‐emitting diodes

open access: yesSmartMat, 2021
Red and near‐infrared (NIR) organic light‐emitting diodes (OLED) have gained remarkable interest due to their numerous applications. However, the construction of highly emissive emitters is hampered by the energy‐gap law and aggregation‐caused quenching (

Room-temperature phosphorescence from metal-free polymer-based materials

open access: yesCell Reports Physical Science, 2022
Summary: Room-temperature phosphorescence (RTP) has received extensive attention in recent years due to its various potential applications. Pure organic RTP materials may overcome the shortcomings of harsh preparation conditions and high toxicity ...

Rydberg aggregates [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2018
We review Rydberg aggregates, assemblies of a few Rydberg atoms exhibiting energy transport through collective eigenstates, considering isolated atoms or assemblies embedded within clouds of cold ground-state atoms. We classify Rydberg aggregates, and provide an overview of their possible applications as quantum simulators for phenomena from chemical ...

Tau Aggregation

open access: yesNeuroscience, 2023
Here we revisit tau protein aggregation at primary, secondary, tertiary and quaternary structures. In addition, the presence of non-aggregated tau protein, which has been recently discovered, is also commented on.

Host–guest materials with room temperature phosphorescence: Tunable emission color and thermal printing patterns

open access: yesSmartMat, 2020
The research of purely organic materials with long afterglow has drawn more and more attention, especially for those with stimulus‐response characteristic. So far, this kind of material is really very scarce and their performance is not good enough.
