This research explores the use of γ‐valerolactone (γ‐VL), a sustainable and low‐toxic solvent, as an alternative for dye‐sensitized solar cell electrolytes. Results indicate that while γ‐VL is less suitable for outdoor applications, it significantly outperforms traditional solvents like acetonitrile and 3‐methoxypropionitrile under indoor lighting ...

Suppressed Thermal Conductivity in van der Waals Semiconductor SnS2 by Stacking Engineering
Achieving low thermal conductivity is crucial for materials used for thermoelectric energy conversion. It is demonstrated that the lattice thermal conductivity of van der Waals semiconductor SnS2 can be significantly reduced by introducing 2H and 4H structures stacked along the c‐axis.

The Bitter Taste of Brazil's Temporary Import Ban on Robusta Coffee
ABSTRACT Brazil, a leading Robusta coffee producer and exporter, faced a significant drought in 2016–2017, which drastically reduced production and depleted stocks. Consequently, Brazil temporarily permitted the import of one million 60‐kg bags of Robusta coffee in the spring 2017. An import ban was imposed shortly afterward due to lobbying by domestic

Achieving Intrinsic Luminescence of Pure Organic Mono‐ and Di‐Radicals in Aggregated States
A versatile strategy enables efficient luminescence of organic radicals in aggregated states by suppressing detrimental interactions, providing insights for solid‐state luminescence applications. ABSTRACT Organic luminescent radicals are promising for optoelectronic applications, yet their practical implementation remains hindered by aggregation‐caused

By employing new protein‐templated AIEgen Ir@BSA as the phosphorescence signal indicator and papain as the biomolecular recognition element, a straightforward protocol for Cys C quantitation has been developed. On‐site quantitation of Cys C in clinical serum samples has been successfully demonstrated using a smartphone‐based portable phosphorescence ...

Germanium‐Based Long‐Conjugation Xanthene Fluorophores for Bioimaging in Optimal NIR‐II Sub‐Window
An NIR‐II dye (EGe5) integrates germanium‐enhanced vibrational suppression and extended conjugation, achieving unprecedented brightness in the optimal NIR‐IIx sub‐window. This design enables high‐contrast visualization of intestinal vasculature and renal labeling, overcoming traditional signal limitations. The tailored spectral properties highlight its

This work establishes a correlation between solvent properties and the charge transport performance of solution‐processed organic thin films through interpretable machine learning. Strong dispersion interactions (δD), moderate hydrogen bonding (δH), closely matching and compatible with the solute (quadruple thiophene), and a small molar volume (MolVol)
