Solid properties

In recent years, the prediction of the effective transport properties have received a great number of investigations. The present work is dedicated to determining the effective permeability of two-dimensional (2D) doubly porous materials made of an isotropic permeable solid matrix in which elliptical shaped pores of any size are embedded. At the interface between the fluid and the solid, the Beaver–Joseph–Saffman conditions are applied.

This study aimed to extract and evaluate some properties and the capability of phenolic components from shallot (Allium ascalonicum L.) peels for usage as fish preservative. It was found that shallot peels extracted twice with 70 % ethanol solvent, within 60 minutes, at 60 oC and the ratio of solid/liquid 1/20 (g/mL) gave highest polyphenol and flavonoid yields. Total polyphenol content and total flavonoid content of the extract were 224.34±5.66 mg GAE/g DW and 255.11±4.35 mg QE/g DW, respectively.

In this study, a simple technique combining conventional electrospinning and facile gas–solid reaction for fabricating PAN/Ag2S nanofibers was presented and tested. The obtained fibers would have excellent properties such as the flexibility of PAN nanofibers and efficient photocatalysis of the Ag2S nanoshells under visible light. The photocatalytic elimination of RhB in water was used to evaluate the activity and application of the synthesized material under visible light irradiation.

In this study, the factors related to the veneer material and adhesive properties were fixed; however, working conditions and process parameters (impregnation, pre-drying, curing, gluing, hot press) could affect the performance of plywood. Therefore, the objective of this work is to investigate the influence of two different processes (with and without curing before gluing) on bonding quality of the treated beech plywood.

With Beech veneers being treated with 10% solid content of the chemicals from paper (Alkyl ketene dimer, AKD), wood (N-methylol melamine, NMM-1) and textile industry (fatty acid modified N-methylol melamine, mNMM-2), the results showed that the treatments with these chemicals considerably increased the water repellence effectiveness (WRE) of veneers in the initial submersion phases. In this paper, veneers treated with Nmethylol melamine and AKD chemicals were investigated on water/moisture related properties and their stability after cyclic tests.
