An overview of the effects of water and moisture absorption on the performance of hemp fiber and its composites

open access: yesSPE Polymers, Volume 6, Issue 1, January 2025.
Hemp fiber‐reinforced composites: Investigating the impact of waterand moisture absorption on their mechanical properties. Abstract Researchers compare natural hemp fibers with synthetic fibers because of their distinct physical and mechanical properties, which have been well established over time.

Hyperbranched polysiloxane functionalized graphene oxide for dicyclopentadiene bisphenol dicyanate ester nanocomposites with high performance

open access: yeseXPRESS Polymer Letters, 2014
We report an efficient and novel method to functionalize graphene oxide (GO) with hyperbranched polysiloxane and successfully compound them with dicyclopentadiene bisphenol dicyanate ester (DCPDCE) to prepare nanocomposites.

L_1-distance for additive processes with time-homogeneous Lévy measures [PDF]

open access: yesarXiv, 2014
We give an explicit bound for the $L_1$-distance between two additive processes of local characteristics $(f_j(\cdot),\sigma^2(\cdot),\nu_j)$, $j = 1,2$. The cases $\sigma =0$ and $\sigma > 0$ are both treated. We allow $\nu_1$ and $\nu_2$ to be equivalent time-homogeneous L\'evy measures, possibly with infinite variation.

Natural Fibre–Reinforced Starch Biocomposites and Their Effects on the Material Mechanical Properties: A Review

open access: yesAdvances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.
Research on biodegradable materials has gained significant attention due to increasing environmental awareness. Starch, as a biodegradable polymer readily available from agricultural resources, is a promising candidate for biocomposite production. Starch‐based films, though exhibiting low mechanical strength, can be enhanced using various plasticizers ...

Le cam theory on the comparison of statistical models [PDF]

open access: yesarXiv, 2016
We recall the main concepts of the Le Cam theory of statistical experiments , especially the notion of Le Cam distance and its properties. We also review classical tools for bounding such a distance before presenting some examples. A proof of the classical equivalence result between density estimation problems and Gaussian white noise models will be ...

FTIR Photoacoustic Spectroscopy Applied to the Curing and Aging of Composites [PDF]

open access: yes, 2005
Fourier-transform infrared photoacoustic spectroscopy has been applied to carbonfiber composites to test whether bulk physical properties of the composites could be determined using the near-surface-sensitive photoacoustic approach.

Recovery of Carbon Fibres From Aged Epoxy Matrix Composites Using H2O2 as an Oxidant: A Thermodynamic and Technoeconomic Analysis

open access: yesJournal of Engineering, Volume 2025, Issue 1, 2025.
There is an effort to use hydrogen peroxide for recycling carbon fibre from epoxy matrix composites because it is an ecofriendly material, and the related technology is feasible. However, there is little information on the technoeconomic impact of this method, thus whether it is economically better than current techniques.

Recent Applications of Sulfonium Salts in Synthesis and Catalysis

open access: yesChemistry – A European Journal, Volume 30, Issue 70, December 13, 2024.
This review summarizes the recent developments on the synthetic applications of sulfonium salts with an emphasis on the description of the operating mechanistic pathways. Abstract The use of sulfonium salts in organic synthesis has experienced a dramatic increase during the last years that can arguably be attributed to three main factors; the ...
