“…Stress anisotropy directly leads to dimensional anisotropy and reduces magnetic coercively [105,106]. erefore, the magnetic fields (indicated by arrows) will have a random and small orientation [15][16][17][18]. Heat treatment increases magnetic induction during structural failure or stress drop and reduces the number of defects [107][108][109].…”

“…Applications related to the field of nanoplasmatic include super lenses, Raman-enhanced surface spectroscopy (SERS), molecular spectroscopy, plasmonic-enhanced fluorescence, quantum computing, energy-dependent photochemical lithography, energy-assisted plasma ionization [11][12][13][14][15]. Silver is more than 50 times cheaper than gold, and because of its unique physicochemical properties, it is a good choice for use in plasmatic applications [16][17][18]. Gold nanoparticles, depending on their size, have good surface plasmon resonance (SPR) and show SPR absorption in the visible light region.…”

Metal nanomaterials with special physicochemical and plasmatic properties have a wide range of applications in various fields including catalysts, plasmon devices, spectroscopy, fuel cell, and various sensors including chemical, colorimetric, and fluorescence sensors. These applications are made possible by controlling the morphology and properties of nanostructures and increasing their selectivity. Various methods have been developed for the synthesis of metal nanostructures, including the use of prefabricated patterns or hard templates such as anodic aluminum oxide and soft molds such as cetyltrimethylammonium bromide (CTAB).

“…are usually used as pseudocapacitive electrode materials [ 2 , 14 , 15 , 16 , 17 ]. Pseudocapacitor electrodes can store energy via reversible faradic redox reactions or ion intercalation into layered structures of electrodes at the electrode/electrolyte interface, and they can reach high specific capacitance and energy density compared to EDLCs [ 18 , 19 , 20 ]. Hybrid supercapacitors can store charge in the combination of EDL and redox reactions.…”

Nowadays, the rapid development and demand of high-performance, lightweight, low cost, portable/wearable electronic devices in electrical vehicles, aerospace, medical systems, etc., strongly motivates researchers towards advanced electrochemical energy storage (EES) devices and technologies. The electrolyte is also one of the most significant components of EES devices, such as batteries and supercapacitors. In addition to rapid ion transport and the stable electrochemical performance of electrolytes, great efforts are required to overcome safety issues due to flammability, leakage and thermal instability. A lot of research has already been completed on solid polymer electrolytes, but they are still lagging for practical application. Over the past few decades, ionic liquids (ILs) as electrolytes have been of considerable interest in Li-ion batteries and supercapacitor applications and could be an important way to make breakthroughs for the next-generation EES systems. The high ionic conductivity, low melting point (lower than 100 °C), wide electrochemical potential window (up to 5–6 V vs. Li+/Li), good thermal stability, non-flammability, low volatility due to cation–anion combinations and the promising self-healing ability of ILs make them superior as “green” solvents for industrial EES applications. In this short review, we try to provide an overview of the recent research on ILs electrolytes, their advantages and challenges for next-generation Li-ion battery and supercapacitor applications.

“…Features of electrochemical behavior of valve metals (Al, Nb, Ta, Ti, etc. ), micro and nanodispersed, nanostructured oxides, including porous and tubular anodic oxides and composite materials based on them, are the objects of numerous studies [ 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ] and review publications [ 11 , 12 , 18 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ]. Particular interest in such materials is due to the fact that they have a quasi-regular structure, which is formed in the process of production as a result of self-organization processes [ 59 ].…”

“…It can be noted that PA and niobia are highly promising for use by lasing, in nanooptic and nanophotonic PCs [ 3 , 54 , 58 , 67 , 73 , 74 , 76 , 105 , 106 , 107 , 108 , 109 ]. On the other hand, PA, the optical and other properties of which have been well studied today, can become a suitable assistant (template) for obtaining nanostructures [ 52 , 95 , 110 , 111 ], including those based on anodic niobia or/and nanocomposites based on a combination of both of these anodic oxides.…”

Three types of niobia nanostructured films (so-called native, planarized, and column-like) were formed on glass substrates by porous alumina assisted anodizing in a 0.2 M aqueous solution of oxalic acid in a potentiostatic mode at a 53 V and then reanodizing in an electrolyte containing 0.5 M boric acid and 0.05 M sodium tetraborate in a potentiodynamic mode by raising the voltage to 230 V, and chemical post-processing. Anodic behaviors, morphology, and optical properties of the films have been investigated. The interference pattern of native film served as the basis for calculating the effective refractive index which varies within 1.75–1.54 in the wavelength range 190–1100 nm. Refractive index spectral characteristics made it possible to distinguish a number of absorbance bands of the native film. Based on the analysis of literature data, the identified oxide absorbance bands were assigned. The effective refractive index of native film was also calculated using the effective-medium models, and was in the range of 1.63–1.68. The reflectance spectra of all films show peaks in short- and long-wave regions. The presence of these peaks is due to the periodically varying refractive index in the layers of films in two dimensions. FDTD simulation was carried out and the morphology of a potential 2-D photonic crystal with 92% (wavelength 462 nm) reflectance, based on the third type of films, was proposed.
