Effect of different lignocellulosic fibres on poly(ε-caprolactone)-based composites for potential applications in orthotics [PDF]

open access: yes, 2015
This work compares the mechanical and thermal behaviour of fully biodegradable biocomposites based on polycaprolactone reinforced with three different natural fibres, namely hemp, sisal and coir, for potential applications in the field of orthoses.

Strength Properties of Surface Modified Kenyan Sisal Fibres

open access: yesJournal of Natural Fibers, 2022
This study aimed at determining and comparing the mechanical properties of natural, mercerized, and cornified sisal fibers. Sisal fiber morphology was modified by mercerization using a 0.06 Molar sodium hydroxide solution and by a seven-hour, seven cycle

Timing of digestion, absorption and assimilation in octopus species from tropical (Octopus maya) and subtropical-temperate (O. mimus) ecosystems

open access: yesAquatic Biology, 2015
Culture of octopuses is still in an experimental stage due to a lack of knowledge about their digestive physiology. This study aimed to determine the temporality of nutrient digestion, absorption and assimilation in 2 species of octopus: the tropical ...

Identification of the Physical and Mechanical Properties of Moroccan Sisal Yarns Used as Reinforcements for Composite Materials

open access: yesFibers, 2021
This work aims to investigate the physical and mechanical properties of sisal fiber and yarn of Moroccan origin. The cellulosic and non-cellulosic constituents of the Moroccan sisal fiber were identified by FTIR spectroscopy.

The Importance of Home Cleaning: Sediment Transport by Alpheid Shrimps Provides a Competitive Advantage to Their Host Anemones

open access: yesFrontiers in Marine Science, 2021
Bartholomea annulata is a facultative host of the A. armatus species complex. In the Mexican Caribbean it is commonly found in cracks and crevices located where the vertical walls meet the sandy bottom or on large coral patches away from the sand.

Impact of Wetting–Drying Cycles on the Mechanical Properties and Microstructure of Wood Waste–Gypsum Composites [PDF]

open access: yes, 2019
Large amounts of wood waste are generated each year in the world. In an attempt to identify a good recovery option for those residues, wood waste from construction and demolition works were used as raw materials in gypsum plasters.
