“…Using the Bi target containing 1% of Au catalyst, and using an Ar/H 2 mixed gas as matter-transport flow, a Bi nanorod growth was found to occur along the [012] direction [43]. Bi nanoparticle growth was also reported by ablation in liquids such as lubricant oils, where the obtained colloidal solution could be very suitable for tribological applications [51]. e crystalline quality of the products prepared by laser-assisted methods is moderate (Figures 9(d) and 9(e)), but the shortcoming is their relative broad size-distribution and/or poor shape-control as shown in Figures 9(f) and 9(g) [51].…”

“…Solution-phase synthesis allows fabrication of Bi nanostructures with a wide control in their shape, either for 0D, 1D, and 2D nanostructures [24, 45-48, 54, 58, 72, 73]. Laserinduced approaches have been successfully used to produce Bi thin films, nanorods, and nanoparticles [34,35,43,51,63]. Molecular beam epitaxy (MBE), electron-beam lithography (EBL), electron-beam irradiation, electromigration (EM), and plasma force have also been used [53,57,62,74].…”

Along the twentieth century, the electronic properties of bismuth have been widely studied, especially in relation with its magnetoresistive and thermoelectric responses. In this context, a particular emphasis has been made on electronic confinement effects in bismuth nanostructures (or nanobismuth). In the recent years, the optical properties of bismuth nanostructures are focusing a growing interest. An increasing number of reports point at the potential of such nanostructures to support plentiful optical resonances over an ultrabroad spectral range: "interband plasmonic" resonances in the ultraviolet, visible, and nearinfrared; dielectric Mie resonances in mid-and far-infrared; and conventional free-carrier plasmonic resonances in the farinfrared and terahertz. With the aim to provide a comprehensive basis for exploiting the full optical potential of bismuth nanostructures, we review the current progress in their controlled fabrication, the trends reported (from theoretical calculations and experimental observations) for their optical and plasmonic response, and their emerging applications, including photocatalysis and switchable metamaterials.

“…Therefore, permanent lubrication of combustion engines is required. Among different approaches to improve lubricants for tribological applications, metallic, e.g., Au, Bi, and Ni [1][2][3][4], and ceramic, e.g., CaCO 3 , CuO, and MOS x [5][6][7][8], nanoparticles were examined [9]. It was found that the magnitude of improvement significantly depends on nanoparticle material, size, shape, and mass concentration [6,7].…”

Colloidal Stability of Metal Nanoparticles in Engine Oil under Thermal and Mechanical Load

Extended colloidal stability and high dispersion degree of nanolubricants are required to avoid nanoparticle deposition in combustion engines and to reduce friction and wear. The simple and rapid one-step technique of pulsed laser ablation in liquids is employed to synthesize precursor-free and highly dispersed gold nanoparticles in lubricants while the colloidal stability is measured by optical spectroscopy and transmission electron microscopy. A remarkable colloidal stability is determined under engine-like and ambient conditions for nine months in terms of constant primary particle size. In contrast to additive-free oils, almost no agglomeration is observed, which might be attributed to the attachment of engine oil additives or pyrolyzed/oxidized molecules to the nanoparticles preventing attractive nanoparticle interactions.

“…Experimental results showed that nanoparticles are most efficient in boundary and mixed lubrication regimes [4,5,9,13,14,[17][18][19]. The nanoparticles are so small that they can enter the contact area easily [3,20], as shown in Fig. 1a (ellipse domain).…”
