“…For industrial applications, colloids are becoming relevant at the multiple-gram-scale, which recently became accessible by LSPC. , Because the processing parameters (e.g., bulk target, solvent and solutes, and system temperature and pressure) and laser parameters (e.g., wavelength, pulse duration, pulse energy, repetition rate, and number of laser pulses) can be flexibly adjusted, a library of NMs covering nearly the entire periodic table can be produced . In addition to the crystalline spheres that are usually generated, soluble, reactive, or supersaturated seed concentrations during LSPC may lead to the formation of nonspherical NMs through ripening, and the resulting morphologies include fractal, − hexagonal, flower-like, , football-like, fullerene-like, leaf-like, nanocube, − nanowire, − nanospindle, , nanoribbon, hollow, − core–shell, − necklace, nanotruffle, nanosheet, − tubular, and nanodisk . These features of LSPC have recently stimulated product commercialization by start-ups on at least three continents, including Particular GmbH in Germany and in-house spin-offs at IMRA in the USA and Hamamatsu Nanotechnology in Japan.…”

Laser Synthesis and Processing of Colloids: Fundamentals and Applications

Driven by functionality and purity demand for applications of inorganic nanoparticle colloids in optics, biology, and energy, their surface chemistry has become a topic of intensive research interest. Consequently, ligand-free colloids are ideal reference materials for evaluating the effects of surface adsorbates from the initial state for application-oriented nanointegration purposes. After two decades of development, laser synthesis and processing of colloids (LSPC) has emerged as a convenient and scalable technique for the synthesis of ligand-free nanomaterials in sealed environments. In addition to the high-purity surface of LSPC-generated nanoparticles, other strengths of LSPC include its high throughput, convenience for preparing alloys or series of doped nanomaterials, and its continuous operation mode, suitable for downstream processing. Unscreened surface charge of LSPC-synthesized colloids is the key to achieving colloidal stability and high affinity to biomolecules as well as support materials, thereby enabling the fabrication of bioconjugates and heterogeneous catalysts. Accurate size control of LSPC-synthesized materials ranging from quantum dots to submicrometer spheres and recent upscaling advancement toward the multiple-gram scale are helpful for extending the applicability of LSPC-synthesized nanomaterials to various fields. By discussing key reports on both the fundamentals and the applications related to laser ablation, fragmentation, and melting in liquids, this Article presents a timely and critical review of this emerging topic.

“…Laser ablation has been employed as a technique to produce hollow nanostructures [22][23][24][25][26][27][28] ; this way the laser induces electronic excitations of the NP which couple to the lattice heating the system. A detailed discus ion of the relation between electronic excitations and thermal effects was given by Gonzalez et al 29 .…”

We present a lyotropic liquid crystal system consisting of SDS/Triton X-100/water at 25°C. This system is respond to pH variations with a phase switch. When pH is altered from alkaline (pH 13) to acidic (pH 2) conditions, phase change occurs from a bicontinuous hexagonal phase to a partially hexagonal phase until it disappears. The hexagonal phase under alkaline conditions is stable. Thus, this system is an ideal candidate for the preparation of pure cubic ZrO 2 nanoparticles. XRD results confirm that the as-synthesized powder is composed of pure cubic ZrO 2 . These nanoparticles also exhibit a thermal stability of up to 800°C. The size and morphological characteristics of the nanoparticles are greatly affected by ZrOCl 2 concentration. The mechanism of zirconia nanoparticle synthesis in a lyotropic hexagonal phase was proposed.
