Impact of Polyamide Surface Preparation on the Formation of Mixed CdS-CdTe Layers

Crystals, 2023
CdTe-CdS layers were formed on polyamide (PA) 6 films with different surface modifications using the sorption-diffusion method. Part of the samples of the PA films was boiled in distilled water for 2 h and the other ones were stored in concentrated ...

Effect of PTFE and Some Additives of Engine Oil on Tribological Properties between Polyamide and Carbon Steel

Tribology Online, 2018
Effect of polytetrafluoroethylene (PTFE) and some additives of engine oil on tribological properties between polyamide (PA) and carbon steel was studied with a pin-on-disk type tribometer. Friction and wear properties of PA were improved by blending PTFE

Combined Effects of Polyamide Microplastics and Hydrochemical Factors on the Transport of Bisphenol A in Groundwater

Separations, 2023
Polyamide (PA) and bisphenol A (BPA) are selected as typical microplastic and endocrine-disrupting chemicals in this study. The adsorption of BPA on the surface of PA and the effect of PA on the transport behavior of BPA in groundwater are systematically

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

, 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.
