Tribenzyl Organic Cations Carried Multidentate X‐Type Lewis Soft Base for High‐Performance Foldable Perovskite Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
This study proposes tribenzyl organic cation carried multidentate X‐type Lewis soft base to enhance adhesion and passivate defects simultaneously, aiming to achieve foldable and efficient perovskite nanocrystal‐based light‐emitting diodes. The resulting pure red F‐PeLEDs exhibit a recorded high EQE of 16.2% and robust mechanical properties to endure ...

Extended complex scalar field as quintessence [PDF]

open access: yesGrav.Cosmol. 9 (2003) 307-310, 2004
In this paper, we show the possibility that an extended complex scalar field can be considered as an extended complex quintessence. For this model, we derive the basic equations with a parameter $\eta $ which govern the evolution of the Universe. Our model may contain a complex quintessence model for $\eta =-1$ and a real quitessence model for $\eta =0$

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Fractional order Taylor's series and the neo-classical inequality

open access: yes, 2010
We prove the neo-classical inequality with the optimal constant, which was conjectured by T. J. Lyons [Rev. Mat. Iberoamericana 14 (1998) 215-310]. For the proof, we introduce the fractional order Taylor's series with residual terms. Their application to

High‐Performance Recyclable Polyester Elastomers Through Transient Strain‐Stiffening

open access: yesAdvanced Materials, EarlyView.
Transient strain‐crystallization simultaneously strengthens and toughens block polyester elastomers while conserving recyclability. Using controlled polymerization catalysis and commercial monomers, block polyester elastomers outperform current commercial elastomers, entering a new region of tensile mechanical property space.
