The heterogeneity of horticultural substrates makes basic physical characteristics, such as total porosity and particle density, difficult to estimate. Due the material source, inclusion occluded pores, hydrophobicity, density values reported from using liquid pyknometry, vary widely. Gas pycnometry was used determine coir, peat, perlite, pine bark, wood substrates. Further precision examined b...

zns/glass thinlayer in high vacuum condition and $40$ degree‎ ‎deposition angle has been produced by resistance evaporated method ‎with $28$ nm thickness‎. ‎cabin deposition temperature zns layer was‎ ‎about $50c$ and substrates were kept at room temperature‎. ‎the atomic ‎force microscopy (afm) and xrd analyses are perfectly accomplished‎ ‎for this layer.‎‎‎
