Ultra-fast and large-quantity (grams) synthesis of one-dimensional ZnO nanowires has been carried out by a novel microwave-assisted method. High purity Zinc (Zn) metal was used as source material and placed on microwave absorber. The evaporation/oxidation process occurs under exposure to microwave in less than 100 s. Field effect scanning electron microscopy analysis reveals the formation of hi...

The oscillation frequencies of charged particles in a Penning trap can serve as sensors for spectroscopy when additional field components are introduced to the magnetic and electric fields used for confinement. The presence of so-called "magnetic bottles" and specific electric anharmonicities creates calculable energy-dependences of the oscillation frequencies in the radiofrequency domain which...

Monitoring of global bio-geophysical processes and their changes, that are due to human activities and natural causes, is of vital importance for earth system research. Microwave remote sensing can play a very significant role in a scientific understanding of the entire earth system. Significant geophysical parameters of land surfaces such as soil moisture, vegetation biomass and snow cover, as...

This article describes a system to investigate the parameters for the remediation of organic vapors using microwave-induced plasma on fluidized carbon granules. The system is based on a single mode microwave apparatus with a variable power (2.45 GHz) generator. Carbon granules are fluidized in a silica tube situated in the sample section of a waveguide incorporating two additional ports to allo...

In this article, a dual-functional microwave system with single input port that can simultaneously be used for antenna and sensor applications is presented. The ability of the proposed achieved by integrating two-port Wi-Fi novel frequency-selective multipath filter (FSMF). FSMF ensures efficient operation not affecting operational bandwidth communicating in presence different sensed materials ...
