Background and objectives: Bakhtiari savory belonging to the Lamiaceae family is an endemic species, which is rich in carvacrol, thymol and other aromatic compounds. The essential oil of the plant could be added in fatty food against radicals similar to synthetic antioxidant BHT. Methods: To determine the best extraction methods on qualitative and antioxidant c...
We describe the ultra-fast and sensitive detection of the gene encoding the protective antigen of Bacillus anthracis the causative agent of anthrax. Our approach employs a highly novel platform technology, Microwave-Accelerated Metal-Enhanced Fluorescence (MAMEF), which combines the use of Metal-Enhanced Fluorescence to enhance assay sensitivity and focused microwave heating to spatially and ki...
Microwave photonics can be generally defined as the study of high-speed photonic devices operating at microwave or millimeter wave frequencies and their use in microwave or photonic systems. In this multidisciplinary field at the interface between microwave techniques, ultra fast electronics and photonic technologies, typical investigations include, for example, high-speed and microwave signal ...
abstract this study is an attempt to determine the effect of nano- technology education on science lesson for fifth grade in primary school in the city of kermanshah. this research is experimental and is conducted in the from of pre-test and post- test for the control group. an achievement test was administered to determine the rate of learning in the students. the research is an applied one. ...
Microwave-assisted organic synthesis is an enabling technology for accelerating drug discovery and development processes. Microwave instruments are used principally in three areas of drug research: the screening of organic drug formulae, peptide synthesis, and DNA amplification. The features of microwave-assisted organic synthesis technology include reduction of time for a chemical reaction, in...
background: in this research, the decomposition of aroclor 1254, including 20 kinds of poly chlorinated biphenyls (pcbs), in real waste transformer oil in the presence of peg1000, naoh, zero valent iron and h2o by microwave (mw) irradiation was studied. methods: central composites design (ccd) method was carried out for experimental design. the effects of microwave power levels (200- 1000 w), r...
The measurement of the microwave field is crucial for many developments in microwave technology and related applications. However, measuring microwave fields with high sensitivity and spatial resolution under ambient conditions remains elusive. In this work, we propose and experimentally demonstrate a scheme to measure both the strength and orientation of the microwave magnetic field by utilizi...
Because microwave products in the consumer electronics market are continuous developing, device and component manufacturers have to seek new advanced integration, packaging and interconnection technologies, as size, cost and performance are critical factors for the success of a microwave product. One of the most promising integration technologies is the multilayer low temperature co-fired ceram...
In the present study, recent progress in using microwave energy to enhance oxidative degradation of pollutants of poor biodegradability in industrial wastewaters is reviewed and evaluated, in order to assess the potential of microwave-induced oxidation as effective and viable remediation technique, alternative to conventional treatment procedures. Microwave radiation is actually emerging as an ...
The fundamentals of microwaves and fixed frequency microwave processing of materials, together with the successful applications of the technology in the United States of America (USA) and Australia, have been described in detail in the paper titled microwave processing of materials: part I. This paper, part II, describes and comments on the fundamentals of variable frequency microwave (VFM) fac...
