[Abstract] Nanodispersed iron oxides obtained using the electroerosion dispersion (EED) technology [1-3] were developed by M. Monastyrov, and used to produce dietary supplement LisoferrinTM and feed additive Nano-Fe+TM. The supplement and additive were certified in Ukraine and Poland.The effects of composition of polyvalent nanodisperse iron oxide, quercetin and vitamin C - LisoferrinTM was studied on 60 women with metabolic syndrome (MS) who were divided equally into the main and control groups. Patients of the main group received dietary supplement LizoferrinTM, patients of the control group received a placebo. Anthropometric indicators, blood plasma glucose fasting and 2h after oral glucose tolerance test (OGTT), fasting blood serum lipids, microvascular endothelium function were determined before and 1 month after use of LizoferrinTM or placebo. The use of LizoferrinTM led to a decrease fasting plasma glucose and glucose level 2h after OGTT in patients with prediabetic disorders. Serum concentration of total cholesterol and low-density lipoproteins cholesterol were decreased in individuals with atherogenic dyslipidemia. Along with this, there was an improvement in the functional state of the endothelium of microvessels, which is evidenced by an increase in the maximum volume velocity of skin blood flow as tested with reactive hyperemia. The beneficial effects of polyvalent nanodisperse iron oxide, quercetin and vitamin C on cardiovascular risk factors were demonstrated by the authors for the first time in patients with metabolic syndrome [4] .The efficiency of nanodispersed iron oxide powder solved in glycerin - nano-Fe+TM was studied during agricultural animal growing. The dosage of nano-Fe+TM feed additive was carried out at the rate of 0.1 mg of powder per 1 kg of live weight of animals per day. According to the results of research, the effectiveness of the nano-Fe+TM during the cultivation of various species and technological groups of agricultural animals (suckling piglets, young pigs in the growing period and young sheep in the growing period) has been established. The use of the nano-Fe+TM contributes to an increase in productivity - increases in the live weight of piglets by 11.4%, young pigs by 7.7%, young sheep by 7.3%. The effectiveness of the nano-Fe+TM is confirmed by the data obtained during the research on the average daily increase in the live weight of animals, the difference between young pigs and sheep during the growing period of the experimental and control groups according to this indicator was statistically significant in favor of the animals of the experimental groups (Р < 0.05). For example, the difference in average daily live weight gains between young pigs of the experimental (403 ± 36 g) and control (343 ± 39 g) groups is 60 g (17.5%).The preservation of the animal population of the experimental groups is at the same level as the control group and is 100%. Nano-dispersed iron oxide powder (nano-Fe+TM) is characterized by its effectiveness during the cultivation of young farm animals and was recommended for use on livestock farms in Ukraine by L. Pogorilyy UkrNDIPVT.

[Abstract] The electrodynamic properties of new composite materials based on AlN and made by the free sintering method, with the addition of diamond powders in the amount of 1-5 wt.% were investigated, in the frequency range of 1-10 GHz. As a result of the studies of the structure and phase composition, it was established by X-ray phase analysis that during the sintering process, the graphitization of diamond powder takes place, and after refining the results obtained by the Rietveld method, show that the content of the graphite phase was 0.8, 1.7, and 3.8 wt.% for the materials in which added diamond powder before sintering in amounts of 1, 3, and 5 wt.%, respectively. The study of electrodynamic characteristics showed an increase in the imaginary and real values of the dielectric constant with an increase in the graphite content. Dielectric losses at 10 GHz increase from 0.05 to 0.08 for composites as the amount of graphite phase increases from 0.8 to 3.8 wt. %. It is shown that at frequencies from 1 to 10 GHz, the real part of the dielectric constant for composite materials of each composition practically does not change, while the imaginary part increases slightly. At the same time, an increase in dielectric losses with increasing content of the graphite phase was noted in the entire measured frequency range.

[Abstract] Ti2InN is the first nitride in the MAX-phase family (into Cr2AlC prototype) for which superconductivity was reported A.D. Bortolozo et al. [1]. It was proposed that the substitution of carbon in Ti2InC for nitrogen increases the superconducting transition temperature from 3.1 K to about 7.3 K due to an increase of the electronic density of states at the Fermi level (EF) from 3.67 for 4.02 states/(eV cell) [1]. The structure of Ti2InN in [1] was characterized only by X-ray. X ray pattern showed peaks of in Ti2InN and the presence of small amount of In. Unfortunately, SEM EDX or TEM studies of the synthesized material were not reported in literature. The Ti2InN samples of the study by Bortolozo et al. [1] In the present study, we prepared samples by different methods. The first two stages of synthesis followed exactly the route described in [1]. The third stage (pressure treatment) was modified. Route1: We repeated the method described in [1] but with 130 bar of nitrogen instead of argon. Route 2: Sintering in Ar in a sealed quartz ampoule. Routes 3, 7 and 8: Spark plasma sintering (SPS) at 38-50 MPa in contact with hBN. Route 4: High pressure-high temperature (HP-HT) sintering under 4 GPa in contact with hBN. Route 5: Repetition of Route 1 after removing air from the furnace more carefully. Using HP-HT, SPS methods and sintering in sealed quartz ampoule in Ar in the third stage (Routes 2, 3, 4, 7 and 8), we succeeded to synthesize Ti2InN samples containing 85.3-94 wt.% of Ti2InN (with lattice parameters a=0.3073(7)-0.3078(8) nm, c=1.4012(4)-1.4030(8) nm, unit cell volume V=114.667´10-3 - 115.114 ´10-3 nm3 ) which demonstrated superconducting behavior with Tc (onset) near 5 K. The samples prepared by SPS and HP-HT methods were highly dense. However, all samples showed a very broad magnetic transition (as susceptibility) not saturating down to 2 K. No macroscopic Meissner phase was established. The magnetization was far too weak to evidence bulk superconductivity of the entire sample (would require around 30 A/m) and hence of Ti2InN. The signal stems either from a minority phase, or from surface superconductivity. According to SEM EDX study, the stoichiometry of the Ti2InN phase of these samples were very close to 211, but in many cases a small excess of nitrogen or the presence of oxygen and even carbon (in one case) were found. We should not exclude that superconductivity in Ti2InN may be very sensitive towards non-stoichiometry (like in the case of oxygen content in YBa2Cu3O7-d , when reduction of oxygen below 6.6-6.5 atoms per one unite cell leads to disappearance of superconductivity) or toward impurities. A pressure of 130 bar of nitrogen was not enough to suppress the decomposition of Ti2InN at 900 oC (Routes 1 and 5). The material decomposed because of In sublimation and aggregation into drops on the top of the samples (a maximum of 54 wt.% Ti2InN was observed in the materials after 10 h heating). The sample prepared by Route 1 demonstrated the best SC behavior, but the amount of Ti2InN was only 6.5 wt.%. Instead, 9 wt. % TiN, 14.5 wt. % In, 61 wt. % TiO2 and 9 wt. % In2O3 were found. The large amount of oxygen containing phases can be explained by the fact that not all air was removed from the furnace before the high nitrogen pressure was created. In the case of Route 5, when air was removed carefully, the sample decomposed as well and contained besides 54 wt.% of Ti2InN, 25 wt. % TiN, 20 wt.% In, and 1 wt.%TiO2 It seems unlikely that using nitrogen instead of argon would allow to overcome this problem (i.e. that 130 bar Ar pressure can prevent In from sublimation from Ti2InN). All our samples contain TiN in the form of separate inclusions (with a small amount of oxygen and a very small amount of indium,). The beginning of the SC transition of all our samples was approximately 5K. The SC transition temperature of TiN was reported to be 5.3-6 K. We did not find a clear correlation between the amount of TiN and the magnetization of the materials. However, the grains of TiN phase are still a candidate for the superconducting phase in our materials. A detailed study of the Ti2InN materials structures which demonstrated Tc=7.3 K would be of great interest. Especially in view of the transition temperatures reported for g-Ti3O5 (7.1 K) and TiO (7.4 K) films.

[Abstract] The increasing demand for the application of hydrogen in different domains of the Global Industry should bring these technologies to the next level of development and contribute with important solutions to significant logistic and energy challenges as well, such as the transportation of gas or liquid hydrogen (LH2). The boiling temperature of LH2 is 20 K, what makes promising application of high temperature superconductors. It has been proposed [1] to construct a centrifugal type LH2-pump (with superconducting bearings, immersed in liquid hydrogen, with an impeller diameter of 32 mm and rotating speed 15 000 rpm.) to fill a 100 l mobile Dewar in about 5 mins. Because of this it is of great importance to understand which comparatively well developed superconducting material can be more stable and efficient in such working conditions. We analyzed the functional superconducting characteristics of MgB2-based bulks without and with additions of Ti, Ti-O and TiC, prepared by hot pressing (30 MPa), spark plasma sintering (50-96 MPa) and under high quasy-hydrostatic pressure (2 GPa) conditions. Their stability in gas hydrogen under 4.2 bar pressure was under the study. The trapped magnetic fields were studied using hollow cylinders of the same geometry prepared from magnesium diboride-based materials and MT-YBCO. The high critical current densities and critical magnetic fields should ensure high trapped fields in all these materials. Indeed all materials demonstrated the required performance; however, flux jumps are a serious issue in MgB2 even in crack free cylinders and impeded higher trapped fields. An inhomogeneous and porous MgB2 structure was found to be less stable against flux jumps. On the other hand, deviations of the material matrices from MgB2 stoichiometry did not impede high Jc and trapped fields. The superconducting properties of all materials investigated in this study occurred to be sufficient for magnets in submersible liquid hydrogen pumps with a required trapped field of about 500-600 mT.

[Abstract] Nanodispersed iron oxides obtained by the electroerosion dispersion (EED) technolog were used to produce dietary supplement LisoferrinTM and feed additive Nano-Fe+TM, developed by M. Monastyrov The supplement and additive were certified in Ukraine and Poland.
The effects of LisoferrinTM (composed from EED nanodispersed iron oxide quercetin and vitamin C) were studied on 60 women with metabolic syndrome. The use of LizoferrinTM led to a decrease of cardiovascular risk factors, fasting plasma glucose and glucose level 2h after OGTT in patients with prediabetic disorders. Serum concentration of total cholesterol and low-density lipoproteins cholesterol were decreased in individuals with atherogenic dyslipidemia. Along with this, there was an improvement in the functional state of the endothelium of microvessels, which was evidenced by an increase in the maximum volume velocity of skin blood flow at test with reactive hyperemia.
The efficiency of nano-Fe+TM (composed from EED nanodispersed iron oxide and glycerin) was studied during agricultural animal and fishes growing. Dosage of nano-Fe+TM was carried out at the rate of 0.1 mg of powder per 1 kg of live weight of animals per day and at 1 mg of nanopowder per 1 kg of feed for fishes. The increase of live weight of piglets by 11.4%, young pigs by 7.7%, 289 and young sheep by 7.3% was observed. The difference in average daily live weight gains between young pigs of the experimental (403 +/- 36 g) and control (343 +/- 39 g) groups was 60 g (17.5%). The preservation of the animal population of the experimental groups was at the same level as the control group - 100 %. After 35 days of study of the effects of nano-Fe+TM microadditive in feed for two-year-old sterlet in mesh cages in water areas of a reservoir with uncontrolled aquatic conditions demonstrated the advantages of the experimental variant over the control one: in terms of individual (+30.7%) and relative gain (+41.8%) body weight, specific growth rate (+41.2%), mass accumulation (+38.3%) and the value of the feed conversion ratio (-31.9%). A positive effect on the results of fish breeding, probably was due to the strengthening of the ability of fish blood to transport oxygen and the corresponding activation of growth and digestion processes.
