In the present study, improvement of salt tolerance in basil (as a salt-sensitive plant) was investigated through silicon (Si) nutrition. Basil plants were subjected to silicon (0, 3 mM) and salinity (0, 50, 100, 150 and 200 mM NaCl) for a duration of one month. Salt stress significantly decreased the biomass of basil. Si supplement (3 mM) resulted in a considerable increase (averagely +135%) i...

To decrease adverse effects of water deficit is foliar application with chemical agents such as silicon. However, there is low information on the influence of silicon on alfalfa under drought stress conditions. Thus, the current study was conducted to assessment the effect of different silicon concentrations (0, 1 and 2 mili Molar concentration) on alfalfa growth trend and biochemical traits, w...

porous silicon layers have been prepared from n-type silicon wafers of (100) orientation. sem, ftir and pl have been used to characterize the morphological and optical properties of porous silicon. the influence of varying etching time in the anodizing solution, on structural and optical properties of porous silicon has been investigated. it is observed that pore size increases with etching tim...

in this paper effect of sio 2 nanoparticles was investigated on potato starch films. potato starch films were prepared by casting method with addition of nano-silicon dioxide and a mixture of sorbitol/glycerol (weight ratio of 3 to 1) as plasticizers. sio 2 nanoparticles incorporated to the potato starch films at different concentrations 0, 1, 2, 3, and 5% of total solid, and the films were dri...

objective: silicon is an effective element in bone biomineralization; hence si-substituted hydroxyapatite can be a relevant bioceramic as bone materials substitution. materials and methods: stoichiometric hydroxyapatite (ha) and si-substituted hydroxyapatite (si-ha) with different contents of si substitution were synthesized successfully by a hydrothermal method using ca(no3)2, (nh4)3po4 or (n...

to investigate the role of silicon (si) in alleviating the effects of salinity on quality and quantity of cut rose flowers ‘hot lady’cultivar was grown in hydroponic culture media. different levels of silicon (0, 50, 100 and 150 mg l-1) as si were mixed with 28 mm nacl (ec ≈3.8 ds m-1) levels, used in an rcbd experimental design.the results indicated that si in 50 and 100 mg l-1 had beneficial ...

In the present paper, the flow and heat transfer of two types of nanofluids, namely, silver-water and silicon dioxide-water, were theoretically analyzed over an isothermal continues stretching sheet. To this purpose, the governing partial differential equations were converted to a set of nonlinear differential equations using similarity transforms and were then analytically solved. It was found...

In this work the conduction of ion-water solution through two discrete bundles of armchair carbon and silicon carbide nanotubes, as useful membranes for water desalination, is studied. In order that studies on different types of nanotubes be comparable, the chiral vectors of C and Si-C nanotubes are selected as (7,7) and (5,5), respectively, so that    a similar volume of fluid is investigated ...
