Light‐Driven Reconfigurable Logic in a Monolithic Perovskite Device via Nonlinear Photoresponse Switching

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a monolithic perovskite OELG device that performs all eight logic operations, including XOR and XNOR, without external bias. Enabled by trap‐engineered MAPbI3:PLL and dual photogates, it achieves reconfigurable logic and parallel decoding of amplitude–frequency signals, supporting scenario‐configured logic‐level separation for ...

Tetraaza[7]–[15]helicenes Synthesized by Two‐Step Strategy: Length‐Controlled Chiral π‐Systems Exhibiting Amplified Circularly Polarized Luminescence

open access: yesAngewandte Chemie, EarlyView.
A modular two‐step strategy provides tetraaza[n]helicenes (n = 7–15) as a homologous series with tunable photophysical and chiroptical properties. Extension beyond n = 11 induces pronounced through‐space π–π interactions, narrowing the energy gap and amplifying circularly polarized luminescence.

Generalized Partially Information Coupled Polar Codes With Arbitrary Coupling Depth and Their Decoding Algorithms

open access: yesIEEE Access, 2021
We propose generalized partially information coupled (PIC) polar codes and their construction method. In the proposed codes, each code block (CB) shares systematic information bits partially with J adjacent CBs on each side, where J is referred to as the

An Enhanced Decoding Algorithm for Coded Compressed Sensing with Applications to Unsourced Random Access

open access: yesSensors, 2022
Unsourced random access (URA) has emerged as a pragmatic framework for next-generation distributed sensor networks. Within URA, concatenated coding structures are often employed to ensure that the central base station can accurately recover the set of ...

Belief Propagation Decoding of Polar Codes on Permuted Factor Graphs

open access: yes, 2018
We show that the performance of iterative belief propagation (BP) decoding of polar codes can be enhanced by decoding over different carefully chosen factor graph realizations.

Enhancing Triplet Excitons Lifetime Through Controlled Intermolecular Interactions

open access: yesAdvanced Optical Materials, EarlyView.
Singlet fission (SF) is investigated in pentacene embedded in a surface‐anchored metal–organic framework, enabling a molecular arrangement inaccessible in pure organic crystals. This architecture changes the singlet fission dynamics significantly and enhances the triplet lifetime by almost four orders of magnitude.
