Titanium nitride (TiN) as a promising alternative to plasmonic metals: a comprehensive review of synthesis and applications

“…Notably, these nanosheet arrays exhibited remarkable outcomes, with a specific capacity of 402.57 C g −1 under a current density of 1 A g −1 , while maintaining an impressive cycling stability of 90% across 2000 charge–discharge cycles. 172 The superior electrochemical performance of the electrode can be ascribed to the optimized thickness and enhanced conductivity of the TiN thin film, as well as the synergistic interaction between NiCo 2 O 4 and TiN. This unique core/shell structure holds promise for high-performance supercapacitors and opens avenues for new electrode fabrication.…”

The first structural, morphological and magnetic property studies on spinel nickel cobaltite nanoparticles synthesized from non-standard reagents

“…1,2 So, spinel nanomaterials are attracting extensive interest due to their wide range of nanotechnological applications in catalysts, magnetic recordings, biomedical devices, electronics, microwave absorbers, gas sensors, magnetism and electrochemical technologies such as batteries, supercapacitors, fuel cells, optical materials/ devices and electrolysers. [3][4][5][6][7] The spinel nanomaterials exhibit a formula of A x B 3Àx O 4 in the cubic spinel structure, in which A and B represent the tetrahedral and octahedral distributions of cations, where A and B are transition metals such as Ni, Zn, Co, Fe, Mn, etc. [8][9][10][11] This spinel structure allows various interesting physicochemical properties due to the different oxidation states of the transition metals and their distribution in the tetrahedral and octahedral sites.…”

“…11,20,21 Recently, many researches have studied NiCo 2 O 4 as a potential candidate for supercapacitors. 2,[5][6][7]11 NiCo 2 O 4 has most success in supercapacitor applications because it offers high redox chemistry and high electrical conductivity, and also exhibits several nanostructures to produce high electrochemical supercapacitive properties. [5][6][7]11 These nanostructures include 1D structures like nanoneedles or nanowires, and 2D structures like platelets, nanosheets or coral.…”

Population abundance of Greater Flamingo Phoenicopterus roseus (Aves: Phoenicopteridae) in district Gurugram of Haryana, India

“…There are not many refractory materials with both metallic and plasmonic characters that are suitable for thermo-photovoltaics and solar-thermal applications and that can replace the precious metals like silver and gold. [1][2][3][4][5][6][7] There is a renewed interest in titanium nitride (TiN) as a plasmonic metamaterial 4,[8][9][10][11] as a cathode material for energy storage [12][13][14][15] and catalysis. [16][17][18] The nanomechanical properties, surface defects and stoichiometry are crucial for the overall device functionality and reliability 5,6,[19][20][21][22][23] .…”
