Effect of Dissolved Hydrogen on Polyamide 11: Observation During Hydrogen Desorption Process After Decompression at Atmospheric Pressure

Journal of Applied Polymer Science, Volume 143, Issue 3, January 15, 2026.
Dissolved hydrogen‐induced plasticization of polyamide 11 (PA11) detected as a decrease in flexural modulus (E f) using Cyclic Three‐Point Bending (Cyc‐3PB). ABSTRACT The effect of dissolved hydrogen on polyamide 11 (PA11) after decompression from a 90 MPa hydrogen gas environment was investigated. Structural analyses using wide‐angle X‐ray diffraction

Positron annihilation study on defect repair of pure iron and RPV steel under electropulsing treatment

He jishu
BackgroundThe defects generated during the working process of metal materials have a significant impact on their performance. For example, the radiation-induced embrittlement and hardening of reactor pressure vessel (RPV) steels are a factor of concern ...

Comparison of the free volume sizes and shapes determined from crystallographic and PALS data

Nukleonika, 2015
Two different classes of molecular crystals were investigated. The first group was benzenediols, which are characterized by the same chemical composition but a different organization of their crystallographic structures; all of the compounds from this ...

Free Volume and Gas Permeation in Anthracene Maleimide-Based Polymers of Intrinsic Microporosity

Membranes, 2015
High free-volume copolymers were prepared via polycondensation with 2,3,5,6,-tetrafluoroterephthalonitrile (TFTPN) in which a portion of the 3,3,3',3'-tetramethyl-1,1'-spirobisindane (TTSBI) of PIM-1 was replaced with dibutyl anthracene maleimide (4bIII)

Mathematical modeling of elementary trapping-reduction processes in positron annihilation lifetime spectroscopy: methodology of Ps-to-positron trapping conversion

, 2017
Methodological possibilities of positron annihilation lifetime (PAL) spectroscopy in application to nanostructurized substances treated within three-term fitting procedure are reconsidered to parameterize their atomic-deficient structural arrangement. In
