Unsubstituted cyclic imides were synthesized from a series of cyclic anhydrides, hydroxylamine hydrochloride (NH2OH.HCl), and 4-N,N-dimethylamino-pyridine (DMAP, base catalyst) under microwave irradiation in monomode and multimode microwaves. This novel microwave synthesis produced high yields of the unsubstituted cyclic imides for both the monomode (61 - 81%) and multimode (84 - 97%) microwaves.

to date, registered users of mobile phone communication network exceeded from total numbers of the world population, while a little knowledge of the biological effects of, 900-1800 mhz microwave radiation, originating from the handsets or the base transceiver stations, have been released. the current study was designed for evaluation of 900-mhz radiation effects on candida albicans proliferatio...

This Special Issue on " Inorganic Syntheses Assisted by Microwave Heating " represents one of the few fully dedicated issues on inorganic microwave synthesis published by any international scientific journal and it features five papers and one review article. Microwave irradiation has been used for many years to accelerate chemical reactions. The very first application of 2.45 GHz microwaves in...

Numerous correlations between magnetic and seismic events unambiguously indicate that the control of earthquakes is a fundamental phenomenon. It proceeds from remarkable physics magneto-plasticity solids, which implies acceleration dislocations by microwaves. The motion provides release dangerous elastic energy earthquake focus transforms into safe plastic deformation. Magneto-plasticity seems ...

Abstract Sending microwaves through bauxite ore allows almost continuous measurement of moisture content during offload by conveyor belt from a ship. Data and results microwave analyser were brought to European Study Group with Industry at the University Limerick, over-arching question whether are accurate enough. The equipment uses linear regression against phase shifts signal attenuation infe...

The paper presents two experimental methods for basalt processing by microwaves, and their results. One method employs a single-mode cavity to melt basalt, and to produce a volcanic glass (obsidian). The other method uses an open-end applicator (i.e. a microwave drill [1]) to form holes in basalt rocks. Experimental observations of the basalt interactions with microwaves in these two schemes ar...

Luneberg lens is a new generation of antennas that is developed in the last few years and inserts itself strongly in Microwaves, Communications and Telescopes area. The idea of this research is to improve the radiation pattern by decreasing the side lobes and increasing the main lobe. The new design is proposed to work in the X-band. The simulated result and analysis are presented. Keywords—Com...
