“…Therefore, aggregation issues that can be found in the other techniques are eliminated. , The heat is generated from the reaction of the chemicals, and thus there is no need for external heat for the reaction to proceed. , Afterward, the reaction is washed with water to remove the salt byproduct, and the metal oxide NPs are sintered at high temperatures to remove any impurities and water. The advantage is the control of the particle size of the metal oxide nanoparticles by modifications in time of milling, sintering, and reactant ratios …”

“…The advantage is the control of the particle size of the metal oxide nanoparticles by modifications in time of milling, sintering, and reactant ratios. 10 The wet synthesis (also called the solvothermal method) utilizes a co-precipitation approach for the synthesis of the metal oxide NPs via displacement reactions from sodium hydroxide. 11−13 In this approach, changes in the concentration of alkali and metal salt can change the outcome of the shape, size, and paramagnetic properties of the metal oxide NPs.…”

To examine the utilization of metal oxide nanoparticles (NPs) in different commercial products, this work focuses on the determination of cost-effective and scalable synthesis protocols. The solvothermal protocol is well-known as a scalable method but has recently been shown to lack economic feasibility. The mechanochemical method has recently been recognized to be a more economic and environmentally friendly substitute for the solvothermal method. In this study, zinc oxide nanoparticles (ZnO NPs) and copper oxide nanoparticles (CuO NPs) were synthesized using two (aqueous and organic) solvothermal (wet) methods and two (manual and automated) mechanochemical (dry) methods. The four methods were evaluated and compared. The automated mechanochemical method generated a significantly higher yield of ZnO NPs (82%) and CuO NPs (84%) using the least energy and time. However, the prepared ZnO NPs displayed higher cytotoxicity against Vero E6 cells when compared to that of CuO NPs. Because of their low cytotoxicity, CuO NPs synthesized via the automated mechanochemical method were selected for application onto cotton fabrics. Lower cytotoxicity was observed for CuO NPs treated fabrics with an IC 50 of 562 mg/mL and ZnO treated fabrics with an IC 50 at 23.93 mg/mL when the treated fabrics were tested against L929 fibroblast cells. Additionally, the cotton fabrics retained bactericidal and virucidal effects after four washes. Thus, the current study recommends the automated mechanochemical method as a cost-effective scalable approach for the synthesis of CuO NPs. The application of CuO NPs onto cotton fabrics generated washable antimicrobial face masks.

“…The main physical method for the preparation of magnetic micro-and NPs mainly revolve around mechanical attrition; the method by which magnetic materials are being ground to a nanometer size. It is easy to operate but has long production cycle [90][91][92]. Among the notable efforts for physical preparation, in 2004, Janot and co-workers used a planetary ball mill equipped with stainless steel bottles to grind iron powder into water at different times, according to the following reaction [93]:…”

As a result of their advantages for superparamagnetic properties, good biocompatibility, and high binding capacity, functionalized magnetic materials became widely popular over the past couple of decades, being applied on large scale in various processes of sample preparation for biomedicine. In this work, we perform an in‐depth review on the current progress in the field of magnetic bead separation, discussing in detail the physical basis of this process, various synthesis methods and surface modification strategies. We place special focus of attention as well on the latest applications of magnetic polymer microspheres in cell separation, protein purification, immobilized enzyme, nucleic acid separation, and extraction of bioactive compounds with low molecular weight. Existing problems are highlighted and possible trends of magnetic separation techniques for biomedicine in the future are proposed.

The efficient degradation of organic pollutants in diverse environmental matrices can be achieved through the synergistic application of piezo‐catalysis and photocatalysis. The focus of this study is on understanding the fundamental principles and mechanisms that govern the collaborative action of piezoelectric and photocatalytic materials. Piezoelectric nanomaterials, under mechanical stress, generate piezo‐potential, which, when coupled with photocatalysts, enhances the generation and separation of charge carriers. The resulting cascade of redox reactions promotes the degradation of a wide spectrum of organic pollutants. The comprehensive investigation involves a variety of experimental techniques, including advanced spectroscopy and microscopy, to elucidate the intricate interplay between mechanical and photoinduced processes. The influence of key parameters, such as material composition, morphology, and external stimuli on the catalytic performance, is systematically explored. This study contributes to the increasing knowledge of environmental remediation and lays the foundation for the development of advanced technologies using piezo and photocatalysis for sustainable pollutant removal.
