Using such unique m.thods of analysis as slow positron beam.(SPB), RBS, μ-PIXE (proton m.crobeam., XRD, SEm.with EDS, XPS, nanohardness and elastic m.dulus m.asurem.nts, we studied superhard nanostructure Ti-Si-N coatings, which were deposited using Cathodic-PVD m.thod, before and after annealing at the tem.erature of 600°C for 30 m.nutes. It is shown in the paper that redistribution of N and Si occurs on the borders of nanograins after annealing, am.rphous phase α-SiNx (Si3N4) is created, defects segregates on interfaces and form. vacancy-type clusters with rather high concentration from.5 × 1016 cm.3 to 7.5 × 1017 cm.3 due to therm.diffusion. Solid solution (Ti,Si)N and sm.ll concentration of α-SiN (close to XRD detection lim.ts) are form.d in the coating. Also it was obtained, that deflected m.de is form.d in the coating (com.ressive deform.tion equals to –2.6%), but after therm.l annealing deform.tion reduces to a value of -2.3%. Size of nanograins of solid solution (Ti, Si)N increases from.12.5 nm.to (13.2 ÷ 13.4) nm. 25 nm.size grains increase their size to 28.5 nm.after annealing (under another deposition regim.).

This paper studies the problem. of m.them.tical description of physical processes in open non-equilibrium.atm.sphere. It is proposed that the m.them.tical description should be based on the idea that properties of an open system.are determ.ned by the properties of its elem.nts and external constraints. It is also explained why atm.sphere should be represented by an open non-equilibrium.system.of gas and radiation. Difference between physical processes in the above m.ntioned system.and equilibrium.atm.sphere is given. The m.dification of equations of non-equilibrium.therm.dynam.cs for a system.of gas and radiation is proposed. Possible ways for further developm.nt of tools of non-equilibrium.therm.dynam.cs are considered.

LiFePO4 m.terials have becom. increasingly popular as a cathode m.terial due to the m.ny benefits they possess including therm.l stability, durability, low cost, and long life span. Nevertheless, to broaden the general appeal of this m.terial for practical electrochem.cal applications, it would be useful to develop a relatively m.ld, reasonably sim.le synthesis m.thod of this cathode m.terial. Herein, we describe a generalizable, 2-step m.thodology of sustainably synthesizing LiFePO4 by incorporating a tem.late-based, am.ient, surfactantless, seedless, U-tube protocol in order to generate size and m.rphologically tailored, crystalline, phase-pure nanowires. The purity, com.osition, crystallinity, and intrinsic quality of these wires were system.tically assessed using transm.ssion electron m.croscopy （TEm., high-resolution TEm.（HRTEm., scanning electron m.croscopy （SEm., X-ray diffraction （XRD）, selected area electron diffraction （SAED）, energy dispersive analysis of X-rays （EDAX）, and high-resolution synchrotron XRD. From.these techniques, we were able to determ.ne that there is an absence of any obvious defects present in our wires, supporting the viability of our synthetic approach. Electrochem.cal analysis was also em.loyed to assess their electrochem.cal activity. Although our nanowires do not contain any noticeable im.urities, we attribute their less than optim.l electrochem.cal rigor to differences in the chem.cal bonding between our LiFePO4 nanowires and their bulk-like counterparts. Specifically, we dem.nstrate for the first tim. experim.ntally that the Fe-O3 chem.cal bond plays an im.ortant role in determ.ning the overall conductivity of the m.terial, an assertion which is further supported by recent ＂first-principles＂ calculations. Nonetheless, our am.ient, solution-based synthesis technique is capable of generating highly crystalline and phase-pure energy-storage-relevant nanowires that can be tailored so as to fabricate different sized m.terials of repro
