Use of Saponins as an Effective Surface Modifier in Cellulose Nanocomposites

The present paper deals with the extraction of saponins from the pericarp of Sapindus mukorossi to use as compatibilizer in nanocomposites. The nanofibrils extracted from banana fibres are utilized as reinforcement of nanocomposite. These nanofibers were treated with Saponin, GPS (3-Glycidoxypropyltrimethoxysilane) and APS (3-Aminopropyltriethoxysilane) to compare the effectiveness of surface treatment. The effectiveness of surface modification was reflected on the increase in mechanical (tensile test, flexural modulus, impact test) properties and decrease in the RMS (Roughness Measurement System) roughness investigation by SFM (Scanning force microscopy) analysis.

Comparação de métodos de determinação da gravidade específica de ovos de poedeiras comerciais

The objective of this work was to compare the results of measuring the specific gravity (SG) of laying hen eggs by using a weighing apparatus and the saline flotation method (SFM). Two hundred eggs from two genetic lines were distributed randomly into two groups of 50 eggs per genetic line and were submitted to two different sequences of SG measurement. Not significant differences were found between the two methods. The weighing apparatus measured the SG of the eggs accurately as the SFM.
