Аннотация: В работе рассматриваются процессы структурообразования в массивных образцах сплава Ni51Ti49 подвергнутых растягивающей нагрузке. Методами электронной микроскопии обнаружены линзовидные кристаллы, имеющие химический состав и структуру, отличающийся от состава матричного сплава. С помощью анализа изгибных экстинкционных контуров на электронно-микроскопических изображениях линзовидных кристаллов сделаны оценки внутренних напряжений в зонах локализации деформации. Показано, что образцы сплава Ni51Ti49 испытавшие множественные циклы прямых и обратных мартенситных переходов обладают ненулевой намагниченностью, вызванной ростом новой ферромагнитной фазы.
The paper deals with the processes of structure formation in massive Ni51Ti49 alloy samples subjected to tensile loading. Electron microscopy revealed lenticular crystals having a chemical composition and structure, wherein the composition of the matrix alloy. By analyzing bending extinction contours on electron microscopic images of lenticular crystals made assessment of internal stresses in the areas of localization of deformation. It is shown that the alloy samples Ni51Ti49 experienced multiple cycles of direct and reverse martensitic transformations have a non-zero magnetization caused by the growth of new ferromagnetic phase.

Аннотация: В работе рассматриваются процессы структурообразования в массивных образцах сплава Ni51Ti49, подвергнутых растягивающей нагрузке. Методами электронной микроскопии и дифракции электронов показана возможность существования фазы с ГЦК-решеткой в никелиде титана. Обнаружено, что межплоскостные расстояния ОЦК110, ГЦКШ и ГПУ002 в исследованном сплаве имеют близкие значения, что свидетельствует о возможности их взаимного полиморфного превращения. С позиции модульной самоорганизации предложена схема мартенситных превращений в никелиде титана из структуры В2 (ОЦК-решетка) в структуру В19' (ГПУ-решетка) через промежуточную фазу с ГЦК-решеткой.
Structure formation in bulk Ni51Ti49 alloy specimens under tensile loading is studied. Electron microscopy and electron diffraction methods are applied to show that a phase with fcc lattice can be present in titanium nickelide. It is found that interplanar spacings bcc110, fcc111 and hcp002 in the studied alloy have close values, which demonstrates the possibility of their mutual polymorphic transformation. A scheme of B2>B19' (bcc>hcp) martensitic transformation through an intermediate phase with fcc lattice is proposed for titanium nickelide from the standpoint of modular self-organization.

    Влияние охлаждения на возникновение намагниченности в никелиде титана / А. В. Достовалов, Ф. М. Носков, В. С. Жигалов, А. В. Нявро // Изв. Алт. гос. ун-та. - 2021. - № 1 (117). - С. 17-20, DOI 10.14258/izvasu(2021)1-02. - Библиогр.: 15 . - ISSN 1561-9443. - ISSN 1561-9451

Аннотация: Вопрос возникновения намагниченности в сплавах системы никель-титан до сих пор изучен недостаточно. Наши ранние работы показали возможность возникновения намагниченности при многократных циклах прямых и обратных мартенситных переходах в сплаве Ni51Ti49, а также после деформации этого сплава растяжением до разрыва. Представленная работа посвящена выявлению эффекта намагниченности в образцах сплава Ni51Ti49 в результате их однократного охлаждения в жидком азоте, а также исчезновению намагниченности при нагревании образцов до комнатной температуры. С помощью индукционного петлескопа выявлено, что непосредственно после охлаждения образец имел высокую намагниченность. По мере нагревания образца петли гистерезиса изменяются, приобретая меньший наклон к горизонтальной оси, что свидетельствует об уменьшении магнитной индукции практически до нуля с повышением температуры до комнатной. Причину появления и исчезновения намагниченности можно связать с микродеформационными процессами, проходящими при охлаждении и нагревании образцов, связанными с прямым и обратным мартенситными переходами.
The occurrence of magnetization in alloys of the nickel-titanium system is still studied insufficiently. Our early work showed the possibility of magnetization arising during multiple cycles of forward and reverse martensitic transitions in the Ni51Ti49 alloy, as well as after deformation of this alloy by tensile stress to rupture. The purpose of this paper is devoted to revealing the effect of magnetization in samples of the Ni51Ti49 alloy as a result of their single cooling in liquid nitrogen, as well as the disappearance of magnetization when the samples are heated to room temperature. Using an induction hysteresigraph it is found out that the sample has a high magnetization immediately after cooling. As the sample is heated, the hysteresis loops change, acquiring a smaller inclination to the horizontal axis. It indicates a decrease in the magnetic induction to almost zero as the temperature rises to room temperature. The reason for the occurrence and disappearance of magnetization can be associated with micro-deformation processes related to forward and reverse martensitic transitions during cooling and heating of the samples.

core-shell magnetic nanoparticles -- magnetite-gold interface -- magnetite-titanium-gold trilayer
Аннотация: The nature of the formation of a chemical bond at the magnetite-gold interface has been studied. The geometric structure and the electronic and magnetic properties of plane layers consisting of magnetite Fe3O4 and gold have been investigated using the DFT-GGA calculation. It has been found that the specific energy and the wetting parameter of the magnetite-gold interface are negative, which leads to the island growth of small Au particles on the Fe3O4 surface. The role of an intermediate thin titanium layer between magnetite and gold has been discussed. The specific energy and wetting parameter of the magnetite-titanium (for thin Ti layers) and magnetite-titanium-gold interfaces are positive. It has been suggested that an intermediate thin titanium layer at the interface between the magnetite nanoparticle surface and the gold layer will make it possible to obtain magnetite nanoparticles with a continuous gold coating.

Using titanium additives to produce high porous tiNi-based alloys with martensitic transformations / S. G. Anikeev, N. V. Artyukhova, M. I. Kaftaranova [et al.] // AIP Conf. Proc. - 2020. - Vol. 2310. - Ст. 020018DOI 10.1063/5.0034809. - Cited References: 13. - The study is funded by the Russian Science Foundation (project No. 19-79-10045)
Аннотация: Structural features of porous TiNi-based materials with Ti additives produced by diffusion sintering have been studied. TiNi powder fraction with a size of 100–160 µm used for sintering provides highly porous material. It is found that increased concentrations of Ti additives decrease the porosity coefficient of the material and increase the volumetric content of the secondary Ti2Ni and Ti4Ni2 (0, N, C) phases. It is shown that Ti powder additives can be used to improve the atomic composition of the TiNi compound.

Titanium nitride nanoparticles as an alternative platform for plasmonic waveguides in the visible and telecommunication wavelength ranges / V. I. Zakomirnyi [et al.] // Photonics Nanostruc. Fundam.

Nanoparticle -- Titanium nitride -- Surface plasmon polariton -- Plasmon waveguide -- Refractory plasmonics
Аннотация: We propose to utilize titanium nitride (TiN) as an alternative material for linear periodic chains (LPCs) of nanoparticles (NPs) which support surface plasmon polariton (SPP) propagation. Dispersion and transmission properties of LPCs have been examined within the framework of the dipole approximation for NPs with various shapes: spheres, prolate and oblate spheroids. It is shown that LPCs of TiN NPs support high-Q eigenmodes for an SPP attenuation that is comparable with LPCs from conventional plasmonic materials such as Au or Ag, with the advantage that the refractory properties and cheap fabrication of TiN nanostructures are more preferable in practical implementations compared to Au and Ag. We show that the SPP decay in TiN LPCs remains almost the same even at extremely high temperatures which is impossible to reach with conventional plasmonic materials. Finally, we show that the bandwidth of TiN LPCs from non-spherical particles can be tuned from the visible to the telecommunication wavelength range by switching the SPP polarization, which is an attractive feature for integrating these structures into modern photonic devices.

Titanium nitride as light trapping plasmonic material in silicon solar cell / N. Venugopal [et al.] // Opt. Mater. - 2017. - Vol. 72. - P. 397-402, DOI 10.1016/j.optmat.2017.06.035. - Cited References: 56 . - ISSN 0925-3467

Photovoltaics -- Plasmonics -- Titanium nitride
Аннотация: Light trapping is a crucial prominence to improve the efficiency in thin film solar cells. However, last few years, plasmonic based thin film solar cells shows potential structure to improve efficiency in photovoltaics. In order to achieve the high efficiency in plasmonic based thin film solar cells, traditionally noble metals like Silver (Ag) and Gold (Au) are extensively used due to their ability to localize the light in nanoscale structures. In this paper, we numerically demonstrated the absorption enhancement due to the incorporation of novel plasmonic TiN nanoparticles on thin film Silicon Solar cells. Absorption enhancement significantly affected by TiN plasmonic nanoparticles on thin film silicon was studied using Finite-Difference-Time-Domain Method (FDTD). The optimal absorption enhancement 1.2 was achieved for TiN nanoparticles with the diameter of 100 nm. The results show that the plasmonic effect significantly dominant to achieve maximum absorption enhancement g(λ) at longer wavelengths (red and near infrared) and as comparable with Au nanoparticle on thin film Silicon. The absorption enhancement can be tuned to the desired position of solar spectrum by adjusting the size of TiN nanoparticles. Effect of nanoparticle diameters on the absorption enhancement was also thoroughly analyzed. The numerically simulated results show that TiN can play the similar role as gold nanoparticles on thin film silicon solar cells. Furthermore, TiN plasmonic material is cheap, abundant and more Complementary Metal Oxide Semiconductor (CMOS) compatible material than traditional plasmonic metals like Ag and Au, which can be easy integration with other optoelectronic devices.

Кл.слова (ненормированные):
defects -- distortions -- lithium titanate -- lithium titanium oxide -- spinel structure
Аннотация: The two primary physical methods for identifying lithium titanate, a negative electrode material used commercially, are X-Ray diffraction and Raman spectroscopy. Although there are many publications on this topic, they are focused mainly on chemistry, so there are still some points that require clarification from a physical and methodological point of view. Difference of experimentally observed and theoretically predicted Raman spectra was explained through a combination of experiments and computations. The work comprises experiments and computations to explain why there are different numbers of predicted and observed Raman-active bands. Our low-temperature study and the analysis of thermal shifts during heating led us to conclude that the approach with surplus bands is advantageous and we recommend using major F2g band shifts to estimate the sample heating.

photonic crystals -- titanium dioxide -- absorbers -- anodization
Аннотация: The anodic TiO2 photonic crystals evoke great interest for application as photocatalytic media due to high absorption of light resuling from their specific structure. In this work, the optical properties of the photonic crystal based on a bamboo-type TiO2 nanotube with a metallic coating are analyzed theoretically by the finite-difference time-domain method. The occurrence of Tamm plasmons that appears as a peak in the absorption spectrum is predicted. A Tamm plasmon polariton is a localized state of light excited at the boundary of two highly reflective media, a metal and a Bragg reflector. The integral absorption of the gold-, titanium-, and titanium nitride-coated photonic crystals in the wavelength range of 450–600 nm is calculated. It is established that the titanium nitride-coated structure exhibits the maximum integral absorption.

The study of the structural properties has shown that titanium ions occupy positions in the interplane columns, which weakens the exchange coupling between the planes. Two anomalies in the temperature dependences of magnetization and heat capacity at 62 and 35 K have been found. It has been supposed that, at 62 K, the long-range magnetic order arises and, at 35 K, a spin-reorientation transition, as in the Pb3Mn7O15 compound, occurs.

Аннотация: Copper-doped titanium oxynitride (TiNxOy) thin films were grown by atomic layer deposition (ALD) using the TiCl4 precursor, NH3, and O2 at 420 °C. Forming gas was used to reduce the background oxygen concentration and to transfer the copper atoms in an ALD chamber prior to the growth initiation of Cu-doped TiNxOy. Such forming gas-mediated Cu-doping of TiNxOy films had a pronounced effect on their resistivity, which dropped from 484 ± 8 to 202 ± 4 μΩ cm, and also on the resistance temperature coefficient (TCR), which decreased from 1000 to 150 ppm °C–1. We explored physical mechanisms causing this reduction by performing comparative analysis of atomic force microscopy, X-ray photoemission spectroscopy, X-ray diffraction, optical spectra, low-temperature transport, and Hall measurement data for the samples grown with and without forming gas doping. The difference in the oxygen concentration between the films did not exceed 6%. Copper segregated to the TiNxOy surface where its concentration reached 0.72%, but its penetration depth was less than 10 nm. Pronounced effects of the copper doping by forming gas included the TiNxOy film crystallite average size decrease from 57–59 to 32–34 nm, considerably finer surface granularity, electron concentration increase from 2.2(3) × 1022 to 3.5(1) × 1022 cm–3, and the electron mobility improvement from 0.56(4) to 0.92(2) cm2 V–1 s–1. The DC resistivity versus temperature R(T) measurements from 4.2 to 300 K showed a Cu-induced phase transition from a disordered to semimetallic state. The resistivity of Cu-doped TiNxOy films decreased with the temperature increase at low temperatures and reached the minimum near T = 50 K revealing signatures of the quantum interference effects similar to 2D Cu thin films, and then, semimetallic behavior was observed at higher temperatures. In TiNxOy films grown without forming gas, the resistivity decreased with the temperature increase as R(T) = – 1.88T0.6 + 604 μΩ cm with no semimetallic behavior observed. The medium range resistivity and low TCR of Cu-doped TiNxOy make this material an attractive choice for improved matching resistors in RF analog circuits and Si complementary metal–oxide–semiconductor integrated circuits.

Microalgae -- Titanium -- Ubiquinone-0 -- Ammonia
Аннотация: Significant process has been made on the development of semi-artificial photosynthesis catering to the production of H2– and CO2– derived value-added products. But there are little reports on the application of semi-artificial photosynthetic system to nitrogen fixation areas. In this study we report the successful and highly efficient N2 fixation in one step at room temperature and ambient pressure by constructing new semi-artificial photosynthetic systems based on material-cell hybrids and microbial photo-electrolysis cells (MPECs). Improved TiO2/Chlorophyll composite that annealed at 400 °C was selected as electron donator to replenish additional electrons to Nostoc commune Vauch microalgae cell for N2 fixation. Ubiquinone-0 (2,3-dimethoxy-5-methyl-1,4-benzoquinone, Q0) was selected as electron relay that guarantees efficient transmission of electrons from abiotic material to microalgae cells. Determined by an ammonia assay kit, at constant concentration of microalgae, the constructed material-cell hybrid system photosynthetically synthesized 40.67 μM/h ammonia, while H-shape MPECs synthesized 132.70 μM/h, 19.23 times higher than that produced by pure microalgae. Using 15N2 as the reduction gas, the constructed H-shape MPECs photosynthetically synthesized 28.37 μM/h 15NH4+, 2.80 time higher than that of the MPECs without Q0 as electron relay.

Аннотация: Regular arrays of plasmonic nanoparticles have brought significant attention over the last decade due to their ability to support localized surface plasmons (LSPs) and exhibit diffractive grating behavior simultaneously. For a specific set of parameters (i.e., period, particle shape, size, and material), it is possible to generate super-narrow surface lattice resonances (SLRs) that are caused by interference of the LSP and the grating Rayleigh anomaly. In this letter, we propose plasmonic structures based on regular 2D arrays of TiN nanodisks to generate high-Q SLRs in an important telecommunication range, which is quite difficult to achieve with conventional plasmonic materials. The position of the SLR peak can be tailored within the whole telecommunication bandwidth (from ≈ 1.26 μm to ≈ 1.62 μm) by varying the lattice period, while the Q-factor is controlled by changing nanodisk sizes. We show that the Q-factor of SLRs can reach a value of 2 × 103, which is the highest reported Q-factor for SLRs at telecommunication wavelengths so far. Tunability of optical properties, refractory behavior, and low-cost fabrication of TiN nanoparticles paves the way for manufacturing cheap nanostructures with extremely stable and adjustable electromagnetic response at telecommunication wavelengths for a large number of applications.

Preparation of polymers based on fullerenes and nanoparticles of titanium carbide and their properties / G. N. Churilov [et al.] // 13th Int. Conf. "Adv. Carbon Nanostructures" : Book of abstracts. - 2017. - Poster session 1: Fullerenes and Nanodiamond Particles. - Ст. P1-14. - P. 83. - Библиогр.: 1 . - ISBN 978-5-93634-037-6
Аннотация: When carbon condensate (CC) is synthesized by spraying graphite rods containing doping powders in arc discharge plasma, usually, in addition to fullerenes, nanoparticles, metal nanoparticles with a carbon shell or nanoparticles of metal carbide are formed [1]. The description of a procedure for the preparation of polymers based on fullerenes and nanodispersed titanium carbide particles and the results of investigation of these polymers will be given in this paper. Titanium and titanium oxide are used as doping powders. The solutions extracted with carbon disulfide are filtered through paper filters. According to X-ray diffraction analysis and transmission electron microscope, the carbon disulphide extract from CC synthesized with the inputting of metallic titanium, does not contain nanoparticles of this metal or its carbide and is characterized by the presence of fullerite clusters (extract 1). While the extract from the CC synthesized with the titanium oxide inputting contains TiC nanoparticles with size of 7–10 nm, while fullerenes are also contained, but in the amorphous state (extract 2) of Fig.1. HPLC analysis of the fullerenes toluene solution, obtained by redissolution of extract 1, allowed to isolate the fullerenes with the usual composition and with the usual ratio between components (C60 – 74.4 %, C70 – 18.9 % and higher fullerenes – 6.7 %). The redissolution of extract 2 in toluene, did not allow to obtain fullerenes solution. Thus, the presence of nanodispersive particles of TiC in the fullerenes solution, upon their drying, leads to polymers formation.
