The aim of this study is to create TiO2 coating on the tile substrate using cell-gel and immersion method. Initially, TiO2 coating was prepared by sol gel method and then, deposition was performed in three stages with different immersion periods of 20, 40 and 60 s and finally, the samples were calcined at 450 °C. The phases and microstructural characteristics of the samples were analyzed using ...
In this research, NTC thermistors with composition of NiMn2-xCoxO4 (x = 0.4, 0.8, 1.2, 1.6) prepared by two methods: solid state reaction and sol-gel (gel-combustion). The average particle size was monitored and structure of the calcinated powders have been investigated using x-ray diffraction (XRD) and tunneling electron microscopy (TEM) techniques. The average particle size was estimated to b...
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...
BACKGROUND Real-time polymerase chain reaction (PCR) is generally regarded as a very accurate and time-saving method, but it is expensive to run. We evaluated the reliability of an inexpensive and a researcher-friendly gel electrophoresis-based PCR method for the quantification of mRNA, and the results were compared with those obtained by real-time PCR. METHODS We compared the results of rela...
INTRODUCTION At present, the polymer gel dosimeter is considered to be the best possible dosimeter for measuring 3-dimesional radiation dose distribution in radiotherapy. These gels are normally toxic; therefore, manufacturing, handling and discarding them require special attention. In order to find less toxic recipe, N-isopropyle acrylamide polymer gel (NIPAM) was introduced. In this study, th...
DNA and cetyltrimethylammonium bromide (CTAB) have been used to prepare gel particles for controlled release studies. This article reports on the release of DNA and CTAB in four different solutions: in sodium bromide, in strong acid, pH 2 and pH 9 solutions for salmon testes DNA-CTAB gel particles. Also, compares results at extreme acid media and 10 mM NaBr solution with higher molecular weight...
Background: Different treatment and protective approaches for radiation-induced oral mucositis have been practiced and have varieties of success. Of which, radioprotective agents, synthetic or natural, have been of great interest for researchers. This study aims to evaluate the effect of curcuma longa topical gel as a herbal production on mucositis induced by radiation therapy of head and neck ...
Aluminophosphate-5 (AlPO4-5) nano-pore zeolite was synthesized. The effect of alteration in precursor gel preparation on the morphology of zeolite was studied. The effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of AlPO4-5 zeolite been studied. A hydrothermal synthesis has been used to produce nano-pore Aluminophosphate-5 c...
