From Insight to Theory: Advancing Sentiment Evaluation for Diaspora Development Projects

open access: yesNew Directions for Evaluation, EarlyView.
ABSTRACT This article develops the concept of “sentiment evaluation,” drawing on a mid‐term evaluation by the Danish Refugee Council (DRC) of its program supporting Somali diaspora activism in Somaliland. Conducted in 2014, the evaluation revealed that “sentiment,” the emotional, identity‐based attachment linking diaspora actors to their homeland ...

Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Strategic construction of fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents for amplifying cancer phototheranostics

open access: yesFlexMat, EarlyView.
The development of conventional phototheranostic nanomedicines suffers from an intrinsic trade‐off between NIR‐II fluorescence emission and phototherapeutic effects, leading to poor overall efficacy. Herein, we propose an innovative fluorination strategy by constructing fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents to ...

Programmable crack dynamics engineering enables flexible strain sensors with high linearity

open access: yesFlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.
