Tuning Excitonic Properties and Charge Carrier Dynamics by Halide Alloying in Cs3Bi2(Br1−xIx)9 Semiconductors

Advanced Optical Materials, EarlyView.
This work studies the effect of halide alloying in Cs3Bi2(Br1−xIx)9 (0 ≤ x ≤ 1) semiconductors. The x = 0.6 shows the smallest bandgap, lowest exciton binding energy, and longest charge carrier lifetimes, showing promising properties for optoelectronic and photocatalytic applications.

Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption

Advanced Optical Materials, EarlyView.
ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Road Segment Traffic Flow Estimation From Sparse Vehicle Trajectory Data Using an Enhanced Macroscopic Fundamental Diagram

IEEE Access
To address the “data silo” challenge in traffic flow data acquisition, this paper proposes a method for estimating urban road segment traffic flow from sparse vehicle trajectory data, predicated on the Macroscopic Fundamental Diagram (MFD).

Thermo‐Derived Cholesteric Liquid Crystal Elastomer Pattern with Composite Structural Colors

Advanced Optical Materials, EarlyView.
A thermochromic cholesteric liquid crystal (CLC) oligomer was synthesized for the preparation of CLC elastomer (CLCE) films with dual reflection bands. Subsequently, a CLCE pattern with composite structural colors was prepared, which was suitably applied for decoration and anti‐counterfeiting.

Modelling of technological reliability in traffic logistic networks in urban areas

MATEC Web of Conferences, 2016
The trend of growing parcel numbers with the customer’s desire for shorter delivery times as a result of increasing online trade and economic specialization requires an adjustment of transport systems.

Exploring the Synergy of Combining BINAP and tCzBN Motifs Within Multi‐Resonant TADF Emitters to Enhance OLED Performance

Advanced Optical Materials, EarlyView.
This work presents two MR‐TADF emitters, BINAP‐BN1 and BINAP‐BN2, based on a BINAP core and differing numbers of tCzBN units. Both emitters show similar solution photophysics, but distinct behavior in doped films, where BINAP‐BN1 exhibits higher photoluminescence quantum yield and suppressed aggregation‐induced emission broadening compared to BINAP‐BN2.
