Electromagnetic fields are created by radiofrequency waves. However, the RF emitted a mobile phone's antenna is insufficient to cause significant heating of tissues in ear or head. The focus this research look further into SAR measurement how much radiation absorbed human body. A CST Microwave studio, high-performance 3D EM analysis software, used for project design, analyse, and measure electr...

The experience, of the authors, in the development and practical use of different programs for 1-D and 2-D simulation of induction heating processes is presented in this paper. A comparison, of simulation versus experimental approach, is discussed. Some examples of 1-D and 2-D computer simulation are presented in this paper for “real world” problems. It’s shown that the accuracy, of computer si...

In this study, the study of drying process using energy a convective electromagnetic field (electromagnetic extremely highfrequency) was considered when obtaining nanocatalyst from bentonite trapping substance based on "Zol-gel" technology. Also, layer "Navbahor" is textural description samples, effect heating size microporosity, surface to surface, distribution and chemical composition porosit...

A bolometer is a device that makes an electrical resistive response to the electromagnetic radiation resulted from a raise of temperature due to heating. The combination of the extremely weak electron-phonon interactions along with its small electron heat capacity makes graphene an ideal material for applications in ultra-fast and sensitive hot electron bolometer. However, a major issue is that...

We report the application of our newly described crystallization technique, which employs silver island films (SIFs) and microwave heating, to rapid crystallization of L-arginine acetate (LAA). Using our technique, LAA crystals (~ 1.2 mm in length) were grown from a 20 μl solution in 1 min on surface functionalized SIFs. In control experiments (glass slides and at room temperature) the growth o...

A highly efficient and scalable microwave assisted synthesis of zirconium-based metal-organic framework UiO-66 was developed. In order to identify the best conditions for optimizing the process, a wide range of parameters was investigated. The efficiency of the process was evaluated with the aid of four quantitative indicators. The properties of the materials prepared by microwave irradiation w...

Traditional hot-injection (HI) syntheses of colloidal nanoparticles (NPs) allows good separation of the nucleation and growth stages of the reaction, a key limitation in obtaining monodisperse NPs, but with limited scalability. Here, two methods are presented for obtaining NPs via rapid heating: magnetic and microwave-assisted. Both of these techniques provide improved engineering control over ...

The flavour and colour of a food product have significant impacts on consumer acceptability. Two of the challenges with microwave food products are that it is often difficult to achieve the desired flavour that matches products prepared in a conventional oven or by frying and to get the browning that the consumer expects. There are reactions that occur in those processes that do not occur when ...

Both theoretical and experimental results on evaluating hidden water in building materials are reported to compare features of optical and microwave heating. Experiments have been performed on a 2 cm-thick reference sample made of gypsum pasteboard which contained voids filled with foamed polyurethane. The obtained results are compared to illustrate that advantages of microwave moisture detecti...

6-Azafulleroid-6-deoxy-2,3-di-O-myristoylcellulose (3) was synthesized from 6-azido-6-deoxycellulose (1) by two reaction steps. The myristoylation of compound 1 with myristoyl chloride/pyridine proceeded smoothly to give 6-azido-6-deoxy-2,3-di-O-myristoylcellulose (2) in 97.0% yield. The reaction of compound 2 with fullerene (C(60)) was carried out by microwave heating to afford compound 3 in h...
