“…Within the scope of alkaline earth metals, only LAL of Mg has been studied. For main group metals, many studies focused on LAL of Al, Bi, Sn [43][44][45][46][47][48][49][50][51][52][53][54][55][56][57], and Ge [58][59][60][61][62][63][64][65][66][67], but few reports are available on Sb [68][69][70], In [71,72], and Pb [73,74]. Transition metals are most frequently investigated for LSPC, which can be transformed into different phases of metals, oxides, sulfides, nitrides, carbides, hydroxides, and metal-polymer composites via reactive laser ablation in liquids (RLAL).…”

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.

“…Numerous emerging nanotechnologies with nanodroplet impact on surfaces as one of the key steps in processing have been developed, such as nanodroplet spray cooling (Kim 2007), nanocoating (Teare 2002), nanoscale inkjet printing (Galliker et al 2012) and nanoscale protein separation and innovative material preparation (Huebner et al 2008;Jambovane et al 2016;Zhu et al 2018;Glasscott et al 2019;Benz et al 2020;Kou et al 2020). Therefore, the detailed mechanisms incorporated in nanoscale impact dynamics have received increasing attention.…”

This study investigates the dynamics of low-viscosity nanodroplets impacting surfaces with static contact angles from θ = 73° to 180° via molecular dynamics (MD) simulations. Two typical morphologies of impacting nanodroplets are observed at the maximum spreading state, a Hertz-ball-like in a low-Weber-number range and a thin-film-like in a high-Weber-number range. Only inertial and capillary forces dominate the impact for the former, whereas viscous force also becomes dominant for the latter. Regardless of morphologies at the maximum spreading state, the ratio of spreading time to contact time always remains constant on an ideal superhydrophobic surface with θ = 180°. With the help of different kinematic approximations of the spreading time and scaling laws of the contact time, scaling laws of the maximum spreading factor ${\beta _{max}}\sim W{e^{1/5}}$ in the low-Weber-number range (capillary regime) and ${\beta _{max}}\sim W{e^{2/3}}R{e^{ - 1/3}}$ (or ${\beta _{max}}\sim W{e^{1/2}}O{h^{1/3}}$ ) in the high-Weber-number range (cross-over regime) are obtained. Here, We, Re, and Oh are the Weber number, Reynolds number, and Ohnesorge number, respectively. Although the scaling laws are proposed only for the ideal superhydrophobic surface, they are tested valid for θ over 73° owing to the ignorable zero-velocity spreading effect. Furthermore, combining the two scaling laws leads to an impact number, $W{e^{3/10}}O{h^{1/3}} = 2.1$ . This impact number can be used to determine whether viscous force is ignorable for impacting nanodroplets, thereby distinguishing the capillary regime from the cross-over regime.

“…While in the plasma jet technique a wide range of reactive oxygen and nitrogen species (RONS) produced by atmospheric pressure non-thermal plasma sources is crucial to this application 22 , 29 . Since plasma-generated RONS alter the chemical makeup of a liquid, plasma-liquid interactions are crucial in the production of nanomaterials 29 – 33 . Ozone, singlet oxygen, hydrogen peroxide, hydroxyl radicals, and nitric oxide are just a few of the common RONS that are created during plasma-liquid interactions 8 , 34 .…”

Given their versatile nature and wide range of possible applications, core–shell nanoparticles (NPs) have received considerable attention. This paper proposes a novel method for synthesizing ZnO@NiO core–shell nanoparticles using a hybrid technique. The characterization demonstrates the successful formation of ZnO@NiO core–shell nanoparticles, which have an average crystal size of 13.059 nm. The results indicate that the prepared NPs have excellent antibacterial activity against both Gram-negative and Gram-positive bacteria. This behavior is primarily caused by the accumulation of ZnO@NiO NPs on the bacteria's surface, which results in cytotoxic bacteria and a relatively increased ZnO, resulting in cell death. Moreover, the use of a ZnO@NiO core–shell material will prevent the bacteria from nourishing themselves in the culture medium, among many other reasons. Finally, the PLAL is an easily scalable, cost-effective, and environmentally friendly method for the synthesis of NPs, and the prepared core–shell NPs could be used in other biological applications such as drug delivery, cancer treatment, and further biomedical functionalization.
