It was found that an increase in the pulse frequency from 13 to 50 kHz and a decrease in the pulse duty cycle from 90 to 80% promotes an increase in the films growth rate by 1.5 – 2 times. The non-monotonous character of the dependence of the film growth rate on the deposition temperature upon pulsed excitation of a glow discharge is similar to that characteristic by direct current. In the optimal pulse mode the maximum film growth rate is near a temperature of 1050°C. With an increase in the deposition time, an increase in the average growth rate of the diamond film is observed. When the synthesis process lasts more than 6 hours, the deposition rate reaches 11 μm / hour. The power consumption in the pulsed mode of diamond films synthesis is 0.3 kW / μm, which is 3 times lower than when using a DC power source.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"74 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85991930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By forming these alloys, previously unknown phase fields of multidimensional phase diagrams are explored. The large number of possible substitutions of constituent elements on crystal lattice sites justifies the dominant contribution of mixing entropy over enthalpy to the free energy reduction. This leads to the formation of phases, which otherwise could not be formed in alloys with fewer main alloying elements. Here we explore magnetic and compositional properties of a High-Entropy Alloy, namely FeCoNiAlx Mnx (0.05 ≤ x ≤ 3.08), composed of magnetic (Fe, Co, Ni) and non-magnetic elements (Al, Mn). By magnetic force microscopy of a selected area, it is observed that for intermediate to low Al and Mn contents, the alloy splits in two major crystallographic phases with different magnetic properties. Elemental maps of the same area were recorded with energy dispersive spectroscopy and scanning electron microscopy. Counterintuitively, it was found that the phase rich in non-magnetic Al has stronger magnetism than the phase rich in Fe. This work showcases possible applications of the here presented HEAs as soft magnetic materials in functional magnetic elements.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"17 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90217781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown, the effects are dose- and size-dependent, and depend on the administration type (puerperal, intratracheal, etc.). Besides, the opposite effects (both cytotoxic and non-toxic) have been observed on the same animals by different authors. Radio protective ability and cytotoxicity of the NDs with sizes 210 nm have been studied on rats with different type of administration with food of aqueous suspensions of NDs homogenized by ultrasound treatment followed by X-ray exposition (5.8g, 5 min).
