Infrared Nano‐Spectroscopy of Single Cell Sections at the Ultrastructural Level

Nanophotonics, Volume 15, Issue 6, 27 March 2026.
Using nano‐FTIR spectroscopy, we resolve subtle differences in infrared absorption among individual subcellular regions of a human cell line with 50 nm spatial resolution. The multichannel information of nano‐FTIR spectra can provide a basis for detailed biochemical interpretation on the ultrastructural level that complement existing electron ...

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 ...

Mechanical, Thermal, and Morphological Properties of PA/NBR TPVs: Influence of Processing Conditions and Recyclability

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Dynamic vulcanization at higher shear rates refines PA/NBR morphology, reduces domain size, and maintains mechanical performance after reprocessing. ABSTRACT Thermoplastic vulcanizates (TPVs) of polyamide 6 and nitrile butadiene rubber (PA/NBR) present excellent mechanical properties but traditionally suffer from performance loss during re‐melt ...
