Original Direct Synthesis of Nanostructured MnO2 in Water by Hydroxylated Ammonium‐Assisted Redox Process

open access: yesParticle &Particle Systems Characterization, EarlyView.
An original and eco‐responsible redox process is reported starting KMnO4 as a cheap precursor and a surfactant in pure water for the efficient synthesis of manganese dioxide nanoworms. Hydroxyethyl ammonium salt as a combined reducing and protective agent is used to produce MnO2 species that are successfully evaluated for selective Csp3‐H ...

What About Susan? Gender in Narnia [PDF]

open access: yes, 2017
Critics of C.S. Lewis argue that his misogyny is present in his portrayal of female characters. While Lewis himself was self-contradictory in his attitudes towards women, his depictions of female characters in The Chronicles of Narnia are both realistic ...

Direct and indirect effects of multiplex genome editing of F5H and FAD2 in oil crop camelina

open access: yesPlant Biotechnology Journal, Volume 23, Issue 5, Page 1399-1412, May 2025.
Summary Mutants with simultaneous germline mutations were obtained in all three F5H genes and all three FAD2 genes (one to eleven mutated alleles) in order to improve the feed value of the seed meal and the fatty acid composition of the seed oil. In mutants with multiple mutated F5H alleles, sinapine in seed meal was reduced by up to 100%, accompanied ...

Effects of amorphous nylon on the properties of nylon 6

open access: yesPolymer Testing, 1997
In this work, the effects of adding small amounts of amorphous nylon (a-nylon) on the properties of nylon 6 have been studied. Blends were prepared in a twin extruder (Brabender). The compositions of a-nylon were varied from 0 to 20 phr. Rheological, thermal, mechanical, and dynamic mechanical properties of the blends were examined using a capillary ...

Non-isothermal crystallization and thermal degradation studies on nylons 7,10 and 10,7 as isomeric odd-even and even-odd polyamides [PDF]

open access: yes
Aliphatic polyamides (nylons) show a remarkable variability in terms of crystallographic structures, polymorphic transitions and crystal morphology despite all polymers of this family have a simple constitution that is based on amide groups and ...

Comparative Analysis of Mechanical and Thermal Characteristics of 3D‐Printed Polyamide using Material Extrusion and Powder Bed Fusion Process with Industrial and Desktop Printers

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 2, February 2025.
The current research compares various 3D printing techniques, utilizing both industrial and desktop printers, on PA's mechanical, structural, and thermal properties. There are no significant differences between the FFF desktop and industrial printers. In fact, in many cases, the tabletop versions outperformed the industrial one.

The Effect of Reprocessing and Moisture on Polyamide Recycling: A Focus on Neat, Composites, and Blends

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 2, February 2025.
The mechanical recycling of polyamides (PA) presents significant challenges, particularly the thermal degradation during reprocessing. This review provides a comprehensive analysis of the effects of reprocessing cycles and moisture in the recycling of PA 6, PA 66, and less studied grades, such as PA 11 and PA 12, along with PA blends and composites ...

WETTABILITIES OF NYLON

open access: yesSen'i Gakkaishi, 1979
Wettability of four Nylon homologues was investigated. The contact angles for various liquids and the heat of immersion were measured to detect the surface wetting property and the whole wettability of Nylon polymers, respectively, and the comparison of these properties was made for each Nylon.The heat of immersion decreases with the increase in the ...
