fibrates, as hypolipidemic drugs known as agonists of peroxisome proliferator-activated receptors, diminish inflammatory responses. studies have shown that incorporation of a silicon atom into a drug structure improves its pharmacological potency, modifies its selectivity toward a given target, or changes its metabolic rate, in addition to increasing the lipophilicity of the compounds. a silico...

Silicon is one of the beneficial elements for plants, recent studies have shown that this element plays a very important role in plant resistance to environmental stresses, including heavy metal stress. To evaluate the effect of silicon foliar spraying on increasing tolerance to lead contamination in dill (Anethum graveolens L) a factorial experiment based on completely randomized design with f...

Reflection spectra of four porous silicon samples under etching times of 2, 6, 10, and 14 min with current density of 10 mA/cm2 were measured. Reflection spectra behaviors for all samples were the same, but their intensities were different and decreased by increasing the etching time. The similar behavior of reflection spectra could be attributed to the electrolyte solution concentration which ...

Water stress is the most important abiotic stress in crop production. Silicium (Si) is the second most abundant element in the soil with beneficial effects on plant tolerance to biotic and abiotic stresses. In order to evaluate the effect of this element in increasing tolerance to water deficit in wheat, a factorial experiment was conducted based on a completely randomized design with three rep...

Basil (Ocimum basilicum L.) belongs to Lamiaceae and is relatively sensitive to salinity. Salinity is one of the most important factors limiting crop production. This study was conducted in a three-replicate completely randomized factorial design to comparative investigate the effects of different concentration of silicon (SiO4-2) application [control (without Si), 1 and 2 mM] and ascorbic acid...

We report the systematic studies on the fabrication of aligned, uniform, and highly dense diamond nanostructures from diamond films of various granular structures. Self-assembled Au nanodots are used as a mask in the self-biased reactive-ion etching (RIE) process, using an O2/CF4 process plasma. The morphology of diamond nanostructures is a close function of the initial phase composition of dia...

in this paper metal-assisted chemical etching has been applied to pattern porous silicon regions and silicon nanohole arrays in submicron period simply by using positive photoresist as a mask layer. in order to define silicon nanostructures, metal-assisted chemical etching (mace) was carried out with silver catalyst. provided solution (or materiel) in combination with laser interference lithogr...

In this paper, we propose to optimize manufacturing methods of memory cells by produced silicon nanoparticles via electrical spark discharge of silicon electrodes in water to reduce the energy consumption for low power applications. The pulsed spark discharge with the peak current of 60 A and a duration of a single discharge pulse of 60 µs was used in our experiment. The structure, morphology, ...

This study aimed at evaluating some quantitative and qualitative properties of potato as one of the main commercial products in Iran. To this end, a split plot experiment on the basis of randomized complete bloke design with silicone and iron was carried out in jiroft as one of the commercial area of planting potatoes. The main factor included different levels of silicon (0, 10, 20, 30 mM.l-1) ...
