High‐performance electro‐optic materials featuring enhanced thermal stability through dual‐donor structural crosslinking engineering

Smart Molecules, EarlyView.
A groundbreaking dual‐donor crosslinking strategy was reported to significantly enhance the thermal stability, achieving remarkable EO coefficients (257–301 pm/V), glass transition temperatures (Tg) ranging from 107–187°C, and ultrahigh chromophore densities (3.73–4.26 × 10²⁰ molecules/cm³) with exceptional long‐term stability after 500 h at 85°C ...

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Approximate resolution convolution function for fitting a dispersion gap measured on a triple‐axis spectrometer

Journal of Applied Crystallography, EarlyView.
An analytical convoluted gap function is presented for fitting either a linear or a quadratic dispersion gap in a constant‐Q cut measured with a focused triple‐axis spectrometer. It outperforms previous methods of fitting a gap, without requiring a full resolution convolution.We present an analytical convoluted gap function for fitting dispersion gaps ...

What Voting Power Cannot Be

Noûs, EarlyView.
ABSTRACT “Almost everyone,” Ronald Dworkin wrote in Sovereign Virtue, “assumes that democracy means equal voting power.” What, then, is voting power? The standard view defines it as the probability that a vote changes the outcome assuming that each possible combination of votes is equiprobable.
