The black walnut (Juglans nigra L.) is an underutilized fruit in the mid-hills of Nepal. However, the physico-chemical properties of Nepalese black walnut are almost unavailable in the literature. Four walnut growing districts namely Baitadi, Dadeldhura, Jumla and East Rukum selected and the black walnut collected at commercial maturity from the local markets. The physical properties w...

Four lignocellulosic materials (walnut shell, chestnut pine wood and burnt wood) were analyzed as biosorbents to remove nickel ions in aqueous solution. The optimal pH condition was determined. Due this, a range of different pHs (3.0 7.5) tested. adsorption isotherms kinetics established. To plot Langmuir Freundlich isotherms, batch tests made with variable concentrations (5 200 mg L−1). pseudo...

In the present work, a new class of polymer composite is developed using walnut shell powder (WSP) as particulate filler in epoxy matrix. Three different sizes WSP are used for preparing three sets composites. The particle size selected 50-micron, 75-micron, and 100-micron. each set composites with size, four compositions i.e., 5 wt. %, 10 15 % 20 fabricated. All prepared have undergone testing...

The Persian walnut (Juglans regia L.) is one of the most valuable resources in Iran because of its multi benefits. The present study was conducted in Meshkin-Shahr in Ardabil province to investigate the important quantitative and qualitative characteristics of 31 walnut genotypes. Classification of genotypes was analyzed using the cluster method. The results showed that among selected walnut ge...

walnut is an important nut crop worldwide. iran is one of the walnut centers of diversity and cultivation. morphological traits and rapd primers were applied to determine genetic diversity among 31 iranian and four foreign walnut genotypes. from 14 rapd primers, 180 bands were amplified among which 174 were polymorphic. the lowest and highest similarity coefficients were 0.37 and 0.89 respectiv...

To apply the nanomaterial as a component in the packaging material structure, in this research, the carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared with three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film wa...

The carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared by adding three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film was investigated. The best result was obtained through the nanocomposite film contain 3% nano...
