Surface amination of poly(acrylonitrile) [PDF]

open access: yes, 1994
The surface amination of poly (acrylonitrile) by ammonia plasma treatment has been studied. Furthermore, two other surface modification techniques have been investigated, the plasma chemical decomposition of an amino group containing chemical (tris-(2 ...

Developing a Suitable Anion Exchange Layer Structure for Pure–Water Fed Bipolar Membrane CO2 Electrolysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A porous anion exchange layer (AEL) is implemented in a forward‐biased bipolar membrane CO2 electrolyzer to suppress carbonate crossover, support CO2 regeneration and maintain cathode alkalinity. Two fabrication strategies are compared—deposition on a silver gas diffusion electrode (GDE) or on the CEM—showing that a porous AEL‐coated GDE provides the ...

Analytical Characterization of Quantum Dot Enhancement Films in Commercial Displays

open access: yesHelvetica Chimica Acta, EarlyView.
Colloidal quantum dots (QDs) are increasingly used in displays, yet many compositions are regulated due to hazardous metal content. Their accurate identification and assessment are therefore essential. Here, a multimodal analytical workflow centered on LA‐ICP‐MS enables spatially resolved identification and classification of QDs in commercial quantum ...

SINGLE AND DUAL ION IRRADIATION EFFECTS ON SWELLING BEHAVIOR OF EP-450 FERRITIC-MARTENSITIC STEEL

open access: yesEast European Journal of Physics, 2015
In spite of all effects of researchers, up to now there is no understanding of the main radiation phenomena advances, in particular, of the swelling at simultaneously effect of damage dose with generated helium and hydrogen. Imperceptions of this problem

Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...

3‐D Nanofabrication of Silicon and Nanostructure Fine‐Tuning via Helium Ion Implantation

open access: yesAdvanced Materials Interfaces, 2022
Despite the continued scaling down of semiconductor manufacturing, traditional lithography‐based nanofabrication only produces thin film structures, not 3‐D shapes.

Pipe and grain boundary diffusion of He in UO₂ [PDF]

open access: yes, 2016
Molecular dynamics simulations have been conducted to study the effects of dislocations and grain boundaries on He diffusion in UO2. Calculations were carried out for the {100}, {110} and {111} h110i edge dislocations, the screw h110i dislocation and Σ5,

Brittle Structural Control and Fluid Progress of the Jinqingding Gold Deposit: Implications for Epizonal Gold Mineralization

open access: yesActa Geologica Sinica - English Edition, EarlyView.
ABSTRACT The Jinqingding gold deposit in eastern Jiaodong is a significant gold mineralization within the Muping–Rushan metallogenic belt. This study integrates structural analysis and trace element geochemistry of sulphides to elucidate ore‐controlling mechanisms and metallogenic models.

Defect landscape engineering suppresses helium damage in ceramics

open access: yesCommunications Materials
Helium accumulation in structural ceramics used in nuclear, fusion, and aerospace systems causes swelling, cracking, and early failure, yet controlling this damage has remained elusive.
