“…Oxide phases are also producible in organic solvents. For example, γ-Al 2 O 3 particles are generated by LAL of Al in ethanol, and post-treatment by means of laser irradiation can only change the particle size, incapable of altering the phases [342], as shown in Table 9 [343][344][345][346][347][348][349][350][351].…”

Diverse nanomaterials, in the forms of carbides, sulfides, oxides, metals, hydroxides, etc., have been synthesized by laser ablation in liquids (LAL) with metal targets as the dominant educts. Many advantages of LAL technique itself and its products have been revealed since 1983 when the first report about LAL was released. Different from traditional wet-chemical synthesis, one unique feature of LAL is its resultant extreme high-temperature and high-pressure local environment for the nucleation and growth of nanomaterials, despite being performed at room temperature. This extreme condition can induce the atomization and ionization of the target materials and liquid molecules to incur different chemical reactions. The laser, liquid, liquid additive, and target can significantly alter the local environment in a broad range. Thus, different phases and shapes of nanomaterials are producible even from the same target. Through directly comparing the products of LAL of 13 kinds of chosen representative metals synthesized under different conditions, this review presents and discusses current understandings, challenging issues, and perspectives related to the diversity of LAL-products, which is willing to promote a deeper investigation and discussion on a clear clarification of the chemical reactions and particle nucleation/growth processes.

“…The pulsed laser ablation technique is a simple, novel, nonpolluting, eco-friendly, low-cost, one-step, and quick method for producing pure metal nanoparticles with regular and minimum buildup [10][11][12][13]. The aim of this study was to synthesize Bi 2 O 3 NPs by laser ablation technique and study their effect as a preservative of contact lenses against eye infections.…”

In this work, bismuth oxide nanoparticles (Bi2O3 NP) were prepared by laser ablation of a solid target in distilled water. The optical and structural properties of Bi2O3 NPs were studied using UV–VIS spectroscopy, energy-dispersive X-ray spectroscopy (EDS), transmission electron microscope (TEM), scanning electron microscopy (SEM), and Fourier transform infrared (FTIR). The results showed that the average particle size is less than 20 nm. The antibacterial activity of the Bi2O3 NPs was determined and compared with amikacin against Acinetobacter baumannii and Staphylococcus aureus. The activity of Bi2O3 NPs was higher than the amikacin. Furthermore, the antibacterial activity of Bi2O3 NPs against S. aureus bacteria was higher than Acinetobacter baumannii; this result was confirmed by studying the effect of Bi2O3 NPs in bacterial biofilm formation in eyes contact lenses using atomic force microscopy (AFM) technique. Taken together, Bi2O3 NPs could be used as a preservative for contact lenses as eye drops to prevent the formation of microbial biofilms in contact lenses.

“…Although reducing the size of NPs is preferable, considering energy release, there are still problems with the oxide layer. A number of publications describe the synthesis processes, and protective coatings of Al, but previous results have not demonstrated high-purity Al content and stability of the particle sizes in a size-controlled distribution of Al-NPs [ 8 , 9 , 10 , 11 ]. Li et al [ 12 ] synthesized Al-NPs using the evaporation process for propulsion applications; however, the produced NPs were not spherical in shape, which is an essential stability criterion.…”

“…The appropriate parameters for the synthesis of Al-NPs are determined. Moreover, the metallic sample, which is prepositioned in an electromagnetic field generated by induction coils of appropriate geometry, is melted and levitated stably [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. It should be mentioned that the experimental setup, which is used in this study, does not require costly equipment and can be upscaled to industrial applications with lower investment costs and expenses.…”

The production of high-purity aluminum nanoparticles (Al-NPs) is challenging due to the highly reactive nature of Al metals. Electromagnetic levitation gas condensation (ELGC) is a promising method to produce high-purity metallic particles as it avoids the interaction between molten metal and refractory-lined, which guarantees the removal of impurities such as oxygen (O). In this research, high-purity Al-NPs were successfully fabricated via ELGC process and fully characterized. The effects of power input and gas flow rate on particle size and distribution were analyzed using field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS), and dynamic light scattering (DLS). The results showed that the Al-NPs have spherical morphologies with an average diameter of 17 nm and size distribution of NPs is narrow under helium (He) flow rate of 15 L/min at a constant temperature of 1683 ± 10 K. The purity of the NPs was confirmed by utilizing X-ray diffraction (XRD), atomic absorption spectroscopy (AAS), and X-ray fluorescence (XRF). Finally, metal purity of 99.976% and 99.97% was measured by AAS and XRF analyses, respectively. Moreover, it was found that increasing gas flow rate and sample temperature results in a decrease in the particle size. The particle sizes for the Al-NPs obtained under He atmosphere were smaller than those obtained under Ar atmosphere.
