“…Equations of state (EOSs) of materials are required for hydrodynamic modeling of processes with high energy concentration [1][2][3]. Such processes take place, for example, during a high-speed collision of bodies [4][5][6], when a substance is exposed to intense laser radiation [7][8][9][10] or beams of high-energy particles [11][12][13], during an electric explosion of conductors [14][15][16][17]. The EOS essentially determines the correspondence of the results of numerical modeling to the physical characteristics of flows arising in the modeled process [2,18,19].…”

“…[229] The intense heat and pressure generated by the plasma expansion rapidly evaporate or sublimate a portion of the material, which is then ejected from the surface. [230][231][232] The material below the surface is not significantly heated, and the ablation process does not cut through the material. This approach is suitable for materials with high melting points.…”

Optoelectronics and photocatalysis are two rapidly developing photonic fields that are revolutionizing green energy, medicine, communications, and robotics. To advance these areas and explore new applications, there is a need for new materials and technologies that enable fast, scalable, and customizable production of high‐performing optoelectronics, including the future development of flexible devices. This review is focused on the strategies to synthesize novel, not fully explored materials and/or enhance their properties using the powerful method of laser processing. The discussion includes the laser treatment of MXenes, Metal‐Organic Frameworks, and perovskites, materials' advantages in terms of structural, electronic, and optical properties, and the role of different laser‐based techniques in boosting their performance. Additionally, there is a demonstration of the existing and potential applications of these three materials and their combinations, especially in optoelectronics and photocatalytic platforms. This review aims to provide a comprehensive understanding of the current state‐of‐the‐art in this field to help researchers identify opportunities and challenges in laser processing of emerging nanomaterials for optoelectronics and photocatalysis.

“…9 The composition of these smaller and larger particles is (slightly) different and can therefore lead to analytical anomalies (elemental fractionation), which are exacerbated by gravitational settling and the variable degree of ionization/excitation during ICP-MS/OES analysis. [10][11][12][13] Plasma chemistry constitutes a complex field of research 14 primarily addressed through the simulation of laser ablation processes in the plume using molecular dynamics. 15 This approach allows researchers to gain a deeper understanding of the underlying mechanisms at play.…”

The composition of particles resulting from pulsed laser ablation is not well understood, although it is anticipated that molecules from the ablated material undergo varying degrees of breakdown, depending on factors such as laser wavelength, energy, pulse width, matrix properties, and gas atmosphere. As reliable arsenic characterization and speciation techniques are available, a fundamental study was undertaken to shed light on the behavior of arsenic compounds (arsenic pentoxide, dimethylarsenic acid, and arsenobetaine within a cellulose matrix, along with pure elemental arsenic), using a pulsed 213 nm Nd:YAG laser and ablation in different gas atmospheres (He, Ar/CO2 [99/1 %], Ar/O2 [80/20 %], and O2) at atmospheric pressure. The generated arsenic, collected in aerosol form on inline syringe filters (0.2 μm), was subjected to sequential dissolution, yielding water-soluble, HCl-soluble, and insoluble fractions. The water-soluble fraction was analyzed for arsenic species using chromatographic techniques in combination with element-specific detection. The analysis revealed that extremely complex processes take place during laser ablation, not only (partially) stripping organoarsenic species from their methyl groups and lowering the valence state, but also creating conditions for the synthesis of methylated arsenic species from arsenic pentoxide and generating more or less soluble nano/micro/macro particles for all arsenic compounds. These findings contribute to a more nuanced understanding of the multifaceted photochemical transformations that may occur during laser ablation of molecules.
