in the present work, magnetic nanocomposites of the multi-walled carbon nanotubes (mwcnts) decorated with magnesium ferrite (mgfe2o4) nanoparticles were synthesized successfully by citrate-gel method. the shape, structure, size, and properties of the as-synthesized sample were characterized by fourier transform infrared spectroscopy (ftir), x-ray diffraction pattern (xrd), transmission electron...

lallemantia royleana (balangu) is a well known iranian medicinal plant that its seed mucilage has many applications in modern pharmacology. plant mucilage traditionally was used as a gel supplement, and natural matrix for sustained release of drugs. but it seems that these compounds are not a simple additive and also have many undiscovered pharmacological properties. in this research, the anest...

this article describes the preparation and analysis of nano hydroxyapatite (ha) films on stainless steel 316l through sol-gel technique. the process started with preparation of a nitrate and phosphate sol. after aging the sol for 24 h at room temperature a ss316 substrate was dip-coated and heat-treated at 350 to 450 °c for different times in air. the coating phase and structure on substrate we...

piroxicam is a non-steroidal anti-inflammatory agent which has an extensive use in rheumatic disorders. since its skin penetration is still a subject for research, the aim of this study was to evaluate the effect of dimethyl sulfoxide on percutaneous penetration of piroxicam gel formulation through skin. in this study, as a model, two types of 0.5% piroxicam new gels, so called red and green ge...

introduction: in radiotherapy, methods of treatment planning are becoming increasingly more complicated. this requires verification of the doses delivered to increasingly smaller and more precise regions. radiotherapy techniques are continuously employing smaller and smaller field sizes to deliver tighter radiation doses with higher therapeutic ratios, generating interest among researchers to p...

in this paper, labo3 perovskite type catalyst formulations were prepared by sol-gel auto combustion method using citric acid as the fuel. activity of catalysts was tested in catalytic oxidation of toluene as a model of volatile organic compounds. lacoo3 perovskite formulation showed the highest activity among labo3 (fe, mn and co) perovskite catalysts. so, lacoo3 perovskite based catalyst was s...

background: baits have become popular and effective formulations against urban insect pests. compared with re­sidual sprays toxic gel baits are used more and more frequently to control urban cockroach populations. the aim of this study was to investigate the usage of two commercially available fipronil and imidacloprid gel bait formulations against blattella germanica field infested in iran. me...
