Neue Versuche mit Spiropyran: Photometrie, NMR‐Spektroskopie und On‐Water‐Synthese

CHEMKON, EarlyView.
Reaktionskinetik wird häufig als schwierig, theoretisch und Mathematik‐lastig empfunden, weshalb experimentelle Zugänge für diesem Themenbereich notwendig sind. In diesem Beitrag werden entsprechende Versuche zur Reaktionskinetik vorgestellt, bei denen das Farbstoffsystem eines Spiropyrans und dessen isomerer Merocyanin‐Form untersucht wird.

225 Jahre UV‐Strahlung – Die Rekonstruktion des Ritter‐Experiments (1801) für Schule und Hochschule

CHEMKON, EarlyView.
Am 22. Februar 1801 gelang Johann Wilhelm Ritter in Jena der experimentelle Nachweis einer unsichtbaren Strahlung jenseits des violetten Bereichs des sichtbaren Spektrums. Als Indikator nutzte er die photochemische Schwärzung von Hornsilber (Silberchlorid) und erbrachte damit erstmals einen indirekten experimentellen Nachweis der ultravioletten ...

Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

Drug Testing and Analysis, EarlyView.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

Recent Advances in Pickering Emulsion Templated Phase Change Material Microcapsules: Design, Fabrication, and Multifunctional Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fabrication process of phase change microcapsules using a Pickering emulsion template method and their subsequent applications. The increasing demand for efficient thermal energy storage systems has driven the development of phase change material microcapsules (PCMMs), which provide high energy‐storage density, reversible phase change, and reduced ...

Phosphorescent Platinum(II) Complexes With Diazinedipyrrolide Pincer Ligands: Structure and Photophysical Properties

European Journal of Inorganic Chemistry, EarlyView.
A new family of phosphorescent Pt(II) complexes with pyrimidinedipyrrolide ligands, including a pyrazine analog, was designed and synthesized. Their emission properties can be finely tuned via ligand modification, revealing strong phosphorescence originating from intraligand charge transfer transitions.

Political Social Identity Threat Predicts Increases in Affective Polarisation Over Time, but Not Changes in Well‐Being

European Journal of Social Psychology, EarlyView.
ABSTRACT Affective polarisation, a growing hostility toward political outgroups, is a phenomenon rooted in social identity. Social identity threat—the expectation of experiencing some form of denigration based on a self‐relevant group identity—is thought to be a major driver of affective polarisation.
