4D Embedded Rotating Black Hole as a Particle Accelerator in the Presence of Magnetic Fields

Universe
We analyze a rotating black hole (BH) in a four-dimensional space-time embedded in five-dimensional flat bulk. In Boyer–Lindquist coordinates, we use a generic extension of the Kerr metric by the line element of Gürses–Gürsey metric.

Influence of Acrylonitrile Content on Processing, Morphology, Thermal Behavior, and Mechanical Properties of PA/NBR Thermoplastic Vulcanizates

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Influence of acrylonitrile (ACN) content on the processing behavior and morphological development of PA/NBR thermoplastic vulcanizates. Torque‐time profiles, SEM, and SEM/AFM images show that an intermediate ACN level (38%) promotes improved phase dispersion and morphological uniformity, especially with increased processing time, resulting in the most ...
