Resolving a Nearly Two-Centuries-Old Mystery: On the Structural Chemistry and Physicochemical Properties of Compounds Associated With the Term Ammelide. [PDF]

Chemistry
The crystal structure of ammelide, also known as melanuric acid, was solved almost 200 years after its discovery by Liebig. Moreover, three modifications of its 1:1 adduct with ammeline were structurally elucidated, consisting of layers with a honeycomb motif analogous to melamine cyanurate.

Heats of formation of lithium perchlorate, ammonium perchlorate, and sodium perchlorate

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1961
Calorimetric measurements of the heats of solution of LiClO4(c), NH4ClO4(e), and NaClO4(c) have been made. The results have been combined with the heats of formation of KClO4(c), KCl(c), LiCl(c), NH4Cl(c), and NaCl(c), to obtain the following heats of formation: LiClO 4 ( c ) , Δ Hf ° ( 25 ° C ) = - 380.27 ± 1.21 kj / mole = - 90.89 ± 0.29 ...

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

Advanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

One-pot hydrothermal synthesis of reduced graphene oxide/zinc ferrite nanohybrids and its catalytic activity on the thermal decomposition of ammonium perchlorate

Journal of Saudi Chemical Society, 2019
Reduced graphene oxide/Zinc ferrite (rGO/ZnFe2O4) nanohybrids are successfully decorated on the surface of the rGO sheets through a simple, one-step hydrothermal method. ZnFe2O4 nanoparticles (NPs) are homogeneously anchored on the rGO sheets.
