Impacts of Fluorination at the Ortho‐Position of Carboxy Groups on Tetrakis(biphenyl)ethene‐Based Hydrogen‐Bonded Framework

Small, EarlyView.
This work provides new findings on the effect of fluorination on the substitution of TPE derivatives and the modulation of the structure and fluorescence properties of hydrogen‐bonded organic framework (HOF) of F‐CBPE. ABSTRACT Fluorination of building block molecules is one of the effective engineering approaches to modulate molecular assembly in ...

A multifunctional near‐infrared dual‐channel off‐on‐off probe for sequential detection of fluoride and hypochlorous acid: Multimatrix applications

Smart Molecules, EarlyView.
This multifunctional, sequence‐specific probe (DHM) enables stepwise detection: fluoride triggers red/near‐infrared emission via cleavage, then hypochlorous acid induces blue fluorescence. It achieves fast, selective visual detection in environmental samples, foods, and in vivo models.

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

Structural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.
