Phenonium‐Ion‐Mediated Skeletal Editing of Paracyclophanes

Angewandte Chemie International Edition, EarlyView.
Phenonium‐ion chemistry enables the modular skeletal editing of paracyclophanes. Regioselective nucleophilic trapping expands one or both aliphatic bridges, enables iterative access to higher paracyclophane homologues, and translates bridge topology into a functional design parameter, as demonstrated with a bridge‐expanded TADF emitter.

Thermal Stability of Aliphatic and Semiaromatic Polyamides: Tailoring the Choice of Isothermal Aging Temperature by Using Kinetic Models of Degradation

Journal of Applied Polymer Science, EarlyView.
Thermogravimetric analysis was performed to study the degradation of aliphatic and semiaromatic polyamides intended for the electrical insulation of future electric aircraft. Using the TGA results, the Flynn and Wall method and Toop's model, the activation energies for the degradation processes were calculated, and kinetic models of the degradation ...

Zn/Al‐NO3 Layered Double Hydroxide as Alternative Activator for Nitrile Rubber Vulcanization: Effect of the Accelerator‐to‐Sulfur Ratio on Curing Kinetics and Network Properties

Journal of Applied Polymer Science, EarlyView.
Zn/Al‐NO3 layered double hydroxide offers a low‐zinc alternative for sulfur vulcanization of nitrile rubber, reducing nominal zinc loading by an estimated 71%. Its potential as a vulcanization activator depends on the curing system: conventional curing preserves tensile strength despite slower kinetics, whereas efficient curing maintains comparable ...

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

Arthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of
