High electrically conductive composites of Polyamide 11 filled with silver nanowires: Nanocomposites processing, mechanical and electrical analysis [PDF]

open access: yes, 2013
Highly conductive composites of silver nanowires and semicrystalline polyamide 11 for different content were prepared. A newmethod was developed to introduce nanowires: a combination of solventway and an extrusion process.

Mechanical and tribological behaviour of PA6 and short aramid fiber composites [PDF]

open access: yesINCAS Bulletin, 2021
This paper presents the results of mechanical and tribological characteristics for two composites: PA6 as matrix and 5% aramid whiskers as additive material and PA6 + 10% aramid whiskers, comparing them to those made of PA6 (polyamide 6).

Nylon 46-polytetramethylene oxide segmented block copolymers [PDF]

open access: yes, 1988
Block copolymers were synthesized from amine-terminated polytetramethylene oxide (PMTO) (Mw 800 and 1130) and polyamide 4,6 salt. First prepolymers were prepared at 200–210°C in the presence of a solvent (pyrrolidone).

In vivo imaging of pyrrole-imidazole polyamides with positron emission tomography [PDF]

open access: yes, 2008
The biodistribution profiles in mice of two pyrrole-imidazole polyamides were determined by PET. Pyrrole-imidazole polyamides are a class of small molecules that can be programmed to bind a broad repertoire of DNA sequences, disrupt transcription factor ...

Inhibition of RNA polymerase II transcription in human cells by synthetic DNA-binding ligands [PDF]

open access: yes, 1998
Sequence-specific DNA-binding small molecules that can permeate human cells potentially could regulate transcription of specific genes. Multiple cellular DNA-binding transcription factors are required by HIV type 1 for RNA synthesis.
