“…Ultrasonic process as a fast, convenient, and economical method has been widely used to generate nanostructure coordination compounds. 25,26 In continuation of our previous research works [27][28][29][30][31] on structural characterization of group XII coordination compounds and effective intermolecular interactions in the crystal packing of them, in the present study, synthesis and spectral characterization of some new mercury complexes are described. Furthermore, the crystal structures of two Hg(II) complexes of (E)-N1-((E)-3-(2-nitrophenyl)allylidene)-N2-(2-((E)-((E)-3-(2 nitrophenyl)allylidene)amino) ethyl) ethane-1,2diamine have been analyzed and compared to the previously reported structures of some other complexes.…”

“…In this way, CuO particle size can be decreased until 12.1 nm. However, the specific structure and dimensions of particles differ depending on the precursor and the treatment conditions [42][43][44]. Hajnorouzi proposed a new method called "direct sonoelectrochemistry" incorporating ultrasonic irradiation in the process of electrolysis of a Cu tip and a physical top-down method, "US ablation" with Cu foil as the starting material to produce CuO NPs [45].…”

Ultrasound (US) technology is already into the research field providing a powerful tool of producing nanomaterials or being implicated in decoration procedures of catalyst supports for energy applications and material production. Toward this concept, low or/and high-frequency USs are used for the production of nanoparticles, the decoration of catalytic supported powders (carbon-based, titania, and alumina) with nanoparticles, and the production of metal-organic frameworks (MOFs). MOFs are porous, crystalline materials, which consist of metal centers and organic linkers. Those structures demonstrate high surface area, open metal sites, and large void space. All the above produced materials are used in heterogeneous catalysis, electrocatalysis, photocatalysis, and energy storage. Batteries and fuel cells are popular systems for electrochemical energy storage, and significant progress has been made in nanostructured energy materials in order to improve these storage devices. Nanomaterials have shown favorable properties, such as enhanced kinetics and better efficiency as catalysts for the oxygen reduction reaction (ORR).

“…In 2015, the Morsali group described the ultrasonic synthesis of [Cu(567)]·(EtOH) 0.5 ·(H 2 O) 1.5 and [Cu(568) 2 ] at 40 kHz for 1 h (Figure ). Interestingly, the same conditions under reflux were also efficient in yielding the expected complexes, but the powder obtained was not nanosized. Regarding silver, the only application of sonochemistry dealt with anion metathesis starting from [Ag(569) 2 ]Cl to yield [Ag(569) 2 ]BF 4 , a photoluminescent complex .…”

Organometallic complexes: these two words jump to the mind of the chemist and are directly associated with their utility in catalysis or as a pharmaceutical. Nevertheless, to be able to use them, it is necessary to synthesize them, and it is not always a small matter. Typically, synthesis is via solution chemistry, using a roundbottom flask and a magnetic or mechanical stirrer. This review takes stock of alternative technologies currently available in laboratories that facilitate the synthesis of such complexes. We highlight five such technologies: mechanochemistry, also known as solvent-free chemistry, uses a mortar and pestle or a ball mill; microwave activation can drastically reduce reaction times; ultrasonic activation promotes chemical reactions because of cavitation phenomena; photochemistry, which uses light radiation to initiate reactions; and continuous flow chemistry, which is increasingly used to simplify scaleup. While facilitating the synthesis of organometallic compounds, these enabling technologies also allow access to compounds that cannot be obtained in any other way. This shows how the paradigm is changing and evolving toward new technologies, without necessarily abandoning the round-bottom flask. A bright future is ahead of the organometallic chemist, thanks to these novel technologies. CONTENTS1. Introduction 7530 2. Technologies 7530 2.1. Grinding and Milling 7530 2.2.
