Abstract:

This paper deals with the fundamental aspect of dielectric relaxations in conducting inorganic solids. It has been shown that it is possible to evidence dielectric relaxations due to charge carriers such as electrons (small-polarons) and ions, dipole reorientations (e.g. water molecules in hydrates) and to interfacial polarization phenomena (e.g. grain boundaries) in polycrystalline compounds. The importance of all these phenomena is discussed in relation to their possible interventions in dielectric spectra.

Abstract:

The Nitrogen doped graphene oxide (NGO) was synthesized by doping N-atoms on graphene oxide (GO) sheet by using melamine which serves as the nitrogen source, through hydrothermal approach. The insertion of nitrogen atoms into the graphene oxide sheet was confirmed by FT-IR, EDS and Raman spectroscopic techniques. We also probed into the tuned dielectric and magnetic properties of NGO due to the decomposition of oxy functional groups of GO and the insertion of pyridinic, pyrrolic and graphitic type nitrogen atoms into the graphitic structure. The dielectric properties were measured by Broadband Dielectric Spectroscopy (BDS). The magnetic behaviour of the sample was demonstrated by Vibrational Scanning Magnetometer (VSM).

Abstract:

Nuclear magnetic resonance (NMR) and broadband dielectric spectroscopy are used to investigate the dynamics of small glass-forming molecules confined to restricted geometries. Ethylene glycol molecules are embedded in the supercages of NaX zeolites. The combined application of NMR and broadband dielectric spectroscopy advances the understanding of the slowing down of the motion near the glass transition temperature of these confined molecules. In combination with nuclear spin relaxation and nuclear magnetic resonance spectroscopy, dielectric relaxation studies on glass forming molecules allow conclusions on the character of the motion. High resolution 1H magic angle spinning (MAS) NMR measurements not only enable a characterisation of the state of the adsorbed molecules via a chemical shift analysis. By means of an analysis of MAS spinning sidebands we may also estimate a correlation time the meaning of which will be discussed in comparison to the results of longitudinal proton spin relaxation measurements. In addition to broadband dielectric spectroscopy slow molecular motions of partially deuterated ethylene glycol adsorbed in NaX are studied by means of 2H NMR line-shape analysis.

Abstract:

Abstract Broadband dielectric spectroscopy (BDS) is a method of characterizing matter from the perspective of its dielectric parameters, which varies depending on the frequency of the applied electromagnetic field. During recent years, along with its many uses, there has been an increase in interest in the use of the method in biomedical fields, especially for the characterization of normal and tumor cells. In this context, this review aims to address in the first part the theoretical bases and mathematical models that explain the principle of operation of the broadband spectroscope. Subsequently, the advantages and limitations of the method are detailed, including the difficulties that the researcher may encounter in the case of working with living cells. Finally, the most important scientific results obtained on normal and pathological cell cultures are presented, possible future research directions being suggested.

Abstract:

Applications for low-temperature cofired ceramics (LTCC) and high-temperature cofired ceramics (HTCC) are advancing to higher frequencies. In order to design ceramic microsystems and electronic packages, the electrical properties of materials must be well characterized over a broad frequency range. In this study, the dielectric properties of commercial aluminum oxide (Al2O3) with different glass loadings are characterized using three different measurement techniques: the split-post cavity, terahertz (THz) time-domain spectroscopy, and Fourier transform IR spectroscopy (FTIR). Specifically, the dielectric properties will be characterized from 10 GHz to IR frequencies. A split-post cavity was employed for determination of dielectric properties in the 10 GHz range. A broadband THz spectroscopy technique was used to characterize the specimens using measured time-domain transmission data. The dielectric constant and loss were extracted from the sample's frequency-domain transmission characteristics, providing data between 100 GHz and 2 THz. Additionally, FTIR was used to characterize the samples from ~33 to 3300 cm−1 (~1–100 THz). The measurements from the three techniques are compared, and dielectric constant and loss data will be presented for commercial and experimental ceramic systems from 10 GHz to IR frequencies.
