Methods For Registering Non-Ionizing Radiation Emitted From The Human Body

European Reviews of Chemical Research, 2015, Vol.(3), Is. 1, pp. 4-24.
DOI: 10.13187/ercr.2015.3.4CrossRef

This paper presents the results of evaluation of possible biophysical methods and approaches for registering of various non-ionizing radiation (NIR) wave types of the human body in the optic and electromagnetic range. Various types of NIR (electromagnetic waves, infrared radiation, thermo radiation, bioluminiscence) emitted from the human body were reviewed. In particular the results on of spontaneous biophoton emission and delayed luminescence from the human body are submitted along with infrared thermography (IRT) results. It was shown that 1 cm2 of skin generally emits 85 photons for 1 s. The intensity of biophoton emission ranges from 10−19 to 10−16 W/cm2 (approx. 1–1000 photons.cm-2.s-1). The specific photon emission from part of the human thumb was detected as a spectrum of various colours with the method of Colour coronal spectral analysis on a device with an electrode made of polyethylene terephthalate (PET hostaphan) with applied electric voltage 15 kV, electric impulse duration 10 s, and electric current frequency 15 kHz. It was established that photons corresponding to a red color emission of visible electromagnetic spectrum have energy at 1,82 еV. The orange color of visible electromagnetic spectrum has energy at 2,05 eV, yellow – 2,14 eV, blue-green (cyan) – 2,43 eV, blue – 2,64 eV, and violet – 3,03 eV. The reliable result measurement norm was at E ≥ 2,53 eV, while the spectral range of the emission was within  = 380–495±5 nm and  = 570–750±5 nm. Also were estimated some important physical characteristics (energy of hydrogen bonds, wetting angle, surface tension) of water by the methods of non-equilibrium energy (NES) and differential non-equilibrium energy (DNES) spectrum of water, that helps understand in general how electromagnetic radiation interacts with water and establish the structural characteristics of water.

Studying of Isotopic Effects of Deuterium in Biological Objects

European Reviews of Chemical Research, 2015, Vol.(3), Is. 1, pp. 25-42.
DOI: 10.13187/ercr.2015.3.25CrossRef

This article describes the data on isotopic effects of deuterium in various biological objects as the cells of methylotrophic, chemoheterotrophic, photoorganotrophic microorganisms, green algae as well as animal cells. It was demonstrated that the increased content of deuterium in water leads to physiological, morphological and cytology alterations of the cell, and also renders negative influence on cellular metabolism, while deuterium depleted water (DDW) with decreased deuterium content on 20–30 % exerts beneficial effects on organism. The maximum kinetic isotopic effect measured at ordinary temperatures in chemical reactions leading to rupture of bonds involving hydrogen and deuterium lies in the range kH/kD = 6–8 for C–H versus C–D, N–D versus N–D, and O–H versus O–D-bonds. By IR-spectroscopy method water samples with varying content of deuterium were investigated.

A Sensitive and Selective Chromogenic Organic Reagent 4-hydroxy-3,5-dimethoxy benzaldehyde-4-hydroxy benzoyl hydrazone (HDMBHBH) for the Direct and Derivative Spectrophotometric Determination of Lead (II)

European Reviews of Chemical Research, 2015, Vol.(3), Is. 1, pp. 43-50.
DOI: 10.13187/ercr.2015.3.43CrossRef

4-hydroxy-3,5-dimethoxy benzaldehyde-4-hydroxy benzoyl hydrazone (HDMBHBH) is used as a novel chromogenic organic reagent for the determination of Lead (II) using spectrophotometry. The novel chromogenic organic reagent 4-hydroxy-3,5-dimethoxy benzaldehyde-4-hydroxy benzoyl hydrazone (HDMBHBH) gave yellow coloured water soluble complex with Pb (II) in basic buffer (pH = 10.0) medium. The colour complex shows maximum absorbance at 386 nm. The system obeyed beer’s law in the concentration range of 0.518–5.18g/ml. The optimum Lead (II) concentration range for accurate determination as evaluated from Ringbom plot was 1.036–4.662 g/ml. The molar absorptivity and Sandell’s sensitivity were 2.66104 L.mol-1.cm-1 and 0.0077 g/cm2 respectively. The Lead (II) forms I:I colour complex with HDMBHBH and stability constant of the complex was found to be 3.42106. The present developed method was successfully applied for the determination of Lead (II) in biological samples.

Chemical bath deposition of In2S3 thin films

European Reviews of Chemical Research, 2015, Vol.(3), Is. 1, pp. 51-55.
DOI: 10.13187/ercr.2015.3.51CrossRef

In2S3 thin films were grown by means chemical bath deposition from acid solution. Calculation of ionic equilibrium with using of thermodynamic constants for systems defines boundary conditions of formation In2S3. Films were characterized by means of XRD, SEM, EDX and XPS methods. According to XRD films have cubic structure of In2S3. XPS method was shown that the surface of In2S3 thin film includes oxygen and carbon contained impurities. SEM confirmed nanosized nature of thin films. Optical band gap of indium(III) sulfide equal to 2.3 eV.

Composition, Structure, Morphology of thin Films Produced by Hydrochemical Deposition in PbSe-CdSe System

European Reviews of Chemical Research, 2015, Vol.(3), Is. 1, pp. 56-68.
DOI: 10.13187/ercr.2015.3.56CrossRef

The area of co-precipitation of lead and cadmium selenide in the reaction system “Pb(CH3COO)2 − CdCl2 − Na3C6H5O7 − NH4OH − CSeN2H4” was calculated taking into account the critical nucleus. Thin films of supersaturated solid solutions CdxPb1−xSe having the cubic structure B1 (NaCl) have been produced by hydrochemical co-deposition of lead and cadmium selenide. The patterns of formation of solid solutions CdxPb1−xSe and the kinetics of their growth depending on the composition of the reaction mixture have been determined. The structure, composition and morphology of PbSe-CdSe thin films were investigated by methods of X-ray energy dispersive analysis and electron microscopic studies.
