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 ...

Rolling circle amplification (RCA) generates single-stranded DNAs or RNA, and the diverse applications of this isothermal technique range from the sensitive detection of nucleic acids to analysis of single nucleotide polymorphisms. Microwave chemistry is widely applied to increase reaction rate as well as product yield and purity. The objectives of the present research were to apply microwave h...

Microwave heating is rapidly emerging as an effective and efficient tool in various technological and scientific fields. A comprehensive understanding of the fundamentals of microwave-matter interactions is the precondition for better utilization of microwave technology. However, microwave heating is usually only known as dielectric heating, and the contribution of the magnetic field component ...

In this paper, we present the design of four different circular bioassay platforms, which are suitable for homogeneous microwave heating, using theoretical calculations (i.e., COMSOL™ multiphysics software). Circular bioassay platforms are constructed from poly(methyl methacrylate) (PMMA) for optical transparency between 400-800 nm, has multiple sample capacity (12, 16, 19 and 21 wells) and mod...

a series of tri- and tetra- substituted imidazoles were synthesized from benzyl, aldehyde and ammonium acetate in the presence of zeolite as an ecofriendly reusable catalyst under microwave irradiation in the absence of solvent. the yields are high to excellent and the use of microwave irradiation reduces reaction times to few minute.

The expeditious synthesis of 2-aryl-benzothia/(oxa)zoles was carried out by the condensation of 2-aminothiophenol/2-aminophenol and diverse aryl aldehydes in presence of Acacia concinna as a biocatalyst under microwave irradiation. The catalytic process is associated with excellent yields, greener reaction conditions and the environmentally friendly microwave technique which are the st...

background: poly chlorinated biphenyls (pcbs) are a class of chlorinated organic chemicals that do not easily degrade in the environment. this study was conducted to determine the effect of microwave rays, hydrogen peroxide, dioxide titanium and ethanol solvent on the degradation of pcbs. methods: a 900w domestic mw oven with a fixed frequency of 2450 mhz was used to provide mw irradiation. ray...

in this work firstly mgfe2o4 nanoparticles were synthesized via a microwave-assisted method. the product was calcinated at 900 ºc for 2h. at the second step zinc oxide shell was synthesized on the ferrite under ultrasonic waves. properties of the product were examined by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and fourier transform infrared (ft-ir) spectroscopy. vibr...

Near-field microwave microscopy has created the opportunity for a new class of electrodynamics experiments of materials. Freed from the constraints of traditional microwave optics, experiments can be carried out at high spatial resolution over a broad frequency range. In addition, the measurements can be done quantitatively so that images of microwave materials properties can be created. We rev...
