White light emitting molecular logic gates

Smart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Two‐Dimensional Materials For Lateral Flow Assays: A Critical Review of Functional Roles and Translational Challenges

VIEW, EarlyView.
2D nanosheets, with large surface area, excellent optical/electrical properties, and high specificity, combine with lateral flow assay strips to enable rapid, readable detection, boosting the strips’ development and applications. Abstract Lateral flow assays (LFAs) are widely used for point‐of‐care diagnostics, but their detection capability remains ...

Crystal Structure and Eu2+ Luminescence of the Lithium Alkaline‐Earth Silicate Fluoride LiBa2SiO4F

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
With Li2BaSiO4F, a new lithium alkaline‐earth silicate fluoride could be synthesized via high‐temperature solid‐state reaction. Crystal structure and luminescence properties upon Eu2+ activation were investigated. A high‐temperature solid‐state synthesis in weld‐shut tantalum ampoules yielded a new alkaline‐earth silicate fluoride, LiBa2SiO4F.

A Surprising Continuation of the Nonisotypic Rb3Ln[AsS4]2 Series: The Diverse Crystal Structures of the End‐Members with Ln = Gd–Ho

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The here presented compounds Rb3Ln[AsS4]2 with Ln = Gd–Ho represent an extension of the nonisotypic Rb3Ln[AsS4]2 series (Ln = La–Nd, Sm, Gd–Ho). The crystal structures of all representatives of this series contain one‐dimensional chains separated by Rb+ cations.

On the abundance of Europium.

The Astrophysical Journal, 1974
The inclusion of the effects of hyperfine splitting can significantly lower the abundance estimate of Eu from singly ionized lines which lie on the flat portion of the curve of growth. In the 21 cool Ap stars studied by Adelman and the five Am stars studied by Smith, the Eu abundance was reduced by 0.4 dex on the average.
