“…Combined with the bio-compatibility of TiN, high absorption efficiency of simple-geometry nanoparticles is of high interest [29]. Titanium nitride nanoparticles in powder form can be fabricated by using nitridation of Ti or TiO 2 at high temperatures, laser ablation of Ti or TiN targets, mechanical alloying, microwave plasma technique, vapor synthesis, reduction-nitridation, and other techniques [16,31,[42][43][44][45][46][47][48]. In this work, aqueous solutions are prepared with commercially available TiN powders (PlasmaChem) with an average nanoparticle size of 50 nm.…”

Optical properties of colloidal plasmonic titanium nitride nanoparticles are examined with an eye on their photothermal and photocatalytic applications via transmission electron microscopy and optical transmittance measurements. Single crystal titanium nitride cubic nanoparticles with an average size of 50 nm, which was found to be the optimum size for cellular uptake with gold nanoparticles [1], exhibit plasmon resonance in the biological transparency window and demonstrate a high absorption efficiency. A self-passivating native oxide at the surface of the nanoparticles provides an additional degree of freedom for surface functionalization. The titanium oxide shell surrounding the plasmonic core can create new opportunities for photocatalytic applications. an excitement to develop technologies for a broad range of applications. The wide range of carrier concentrations available from several material classes spans the electromagnetic spectrum from the ultra-violet through the midinfrared [2]. Additionally, the broad variety of materials studied in the field provide extra degrees of freedom to solve technological challenges thanks to the unique properties such as tunability, process compatibility, chemical stability, etc [3]. KeywordsTransition metal nitrides, especially titanium nitride (TiN), have been studied for the last three decades due to the unique combination of their material properties [4]. Metallic behavior of TiN combined with its hardness and chemical stability has attracted attention in microelectronics research [5]. Adjustable optical properties and stoichiometry of TiN thin films were examined in the 1990s [6]. The optical characterization of TiN thin films was extensively performed later with the increasing interest in the field of plasmonics [7][8][9][10]. Improved properties with epitaxial TiN thin films have recently been demonstrated with a hyperbolic metamaterial and a plasmonic waveguide [11,12]. As a refractory plasmonic material, TiN holds the potential to solve critical issues associated with the softness and low melting points of plasmonic metals such as gold and silver [13,14]. In contrast to thin films, TiN nanoparticles have not been extensively studied until recently. Localized surface plasmons (LSPs) in TiN nanoparticles were first theoretically analyzed by Quinten [15], while their first experimental demonstration was performed by Reinholdt et al. [16] In their work, cubic nanoparticles smaller than 10 nm with a broad size dispersion were fabricated through laser ablation, and plasmon resonance peaks centered around 730 nm wavelength were reported. Reinholdt et al. proposed the use of TiN nanoparticles as inorganic, stable color pigments. We have previously shown that TiN nanoparticles provide field enhancement comparable to that achievable with Au, with a broader peak spectrally positioned in the biological transparency window [17]. In a more recent study, we experimentally analyzed the absorption efficiencies of lithographically fabricated TiN and Au nanoparticles an...

“…Nanotechnology also has revealed commercial potential for the textile industry. Becauseconventional methods used to impart different properties to fabrics often do not lead to permanent effects, and will lose their functions after wearing or laundering [7]. Nanotechnology can reduce the use of water as the nanostructure and surface functionality can be imparted using dry techniques on fabric [8].…”

“…Revolutionary of nanotechnology and biotechnology have paved the way to complement these size similarities and intrinsic fea-tures of biomolecules with unique properties of nanopar-ticles to yield novel biomolecule-nanoparticle hybrid of synergistic characteristics and functions [12] Biomolecules also display several fundamental features that can be utilised as future build-ing blocks for nanoparticle architecture. For example, the nature-evolved multiple binding sites of biomolecules in addition with its catalytic properties could facilitate the development of multifunctional nanoparticles [13].Silica nanoparticles attract a great deal of attention as they are used in logic gates, memory devices, lightemitting devices, sensors, bio-imaging, energy storage, and textilefieldand photonic applications [7].…”

In this study,two ways were carried out inthe polyesterfabric, which used in traditional swimsuit manufacturing,Firstly the polyester fabric werecoated with the silica nanoparticles to improve its functional properties for achieve the final use requirements. The characterization of silica nanoparticles on the fabric surface were done by using scanning electron microscope (SEM)and also on fabric surface before the treatment.Functional and Physical tests were accomplished. Those tests were weight, thickness, bursting Strength, stiffness, air permeability, water repellency. The properties of polyester fabrictreated with the silica nanoparticles were compared with untreatedpolyester fabric.Secondly Sharkskin topography was used as guide for the changing the polyesterfabric surface morphology and it was applied by photochemical method technique usingGlycerol propoxylatetriacrylate(HH-IV Water Resistant Diazo Emulsion) on the polyester fabric.Thepolyester fabric surfaces with photochemicaltechnique,polyester fabric that treated with the silica nanoparticles anduntreated polyester fabricwere tested to measure its speed, with different weights on the water.The new polyester fabric surface may increase the efficiency of swimsuit.
