“…Some general principles of nanosized particle formation by the use of microreactors with impinging jets are discussed in our paper [1]. Though there are some general ideas applicable to any type of microreactor [2][3][4][5], the microreactors with swirled flows have some peculiarities described in the present paper.…”

“…From a practical point of view, the most convenient tool for the "design" of nanosized particles would be a hypothetical device that allows one to select the desired atoms and place them in the lattice of the crystals being grown in a proper way. Although certain attempts in this direction (hereinafter we will call it the "nano-approach") could be done, e.g., based on the use of powerful electromagnetic fields (which were applied for instance for catalytic reactions [2,3,6,7]) and it is possible to imagine the use of nanorobots (which are quite widely studied for biomedical application [4,5,8,9]). The advantage of this approach appears to be the guaranteed selectivity, but the performance of this approach for the synthesis of nanosized particles is still a challenge due to some technical limitations.…”

Micromixing and Co-Precipitation in Continuous Microreactors with Swirled Flows and Microreactors with Impinging Swirled Flows

One of the promising methods for process intensification for micromixing, co-precipitation, and crystallization in continuous reactors is the use of vigorous vortices. A combination of the high intensity of the kinetic energy input with the small volume of the micromixing volume allows to concentrate the energy dissipation rate up to 104 W/kg and more. As the embodiment of such an idea, four new types of microreactors with intensively swirled flows were created and studied as a tool for continuous co-precipitation and crystallization. A correlation between residence time and segregation index was found: the smaller residence time, the higher energy dissipation rate and better quality of micromixing. A method for the synthesis of oxides of a number of transition metals in microreactors with intensively swirled flows with subsequent thermal treatment of co-precipitation products has been developed. This method was used to obtain ensembles of nanosized particles of zirconium oxides, as well as calcium and strontium fluorides. In comparison with the currently widely used hydro- and solvothermal methods, the proposed method has high productivity (around 10 m3/day for lab scale device), can significantly reduce the duration of the process, provides low energy consumption, does not require a large number of labor-intensive operations, is technologically advanced and easily scalable.

“…This design (inspired by the movement of earthworms) has the advantage of realizing large volume changes (maintaining its high strength) under low-power magnetic fields. To conclude, several recent studies have also contributed to the evolving landscape of soft robot locomotion [108,253,417,[425][426][427][428], highlighting the diverse and dynamic nature of this rapidly progressing field. Figure 21 exemplifies additional instances of multimodal capabilities and actuator applications within the domain of soft robotics.…”

Hard-magnetic soft materials (hMSMs) are smart composites that consist of a mechanically soft polymer matrix impregnated with mechanically hard magnetic filler particles. This dual-phase composition renders them with exceptional magneto-mechanical properties that allow them to undergo large reversible deformations under the influence of external magnetic fields. Over the last decade, hMSMs have found extensive applications in soft robotics, adaptive structures, and biomedical devices. However, despite their widespread utility, they pose considerable challenges in fabrication and magneto-mechanical characterization owing to their multi-phase nature, miniature length scales, and nonlinear material behavior. Although noteworthy attempts have been made to understand their coupled nature, the rudimentary concepts of inter-phase interactions that give rise to their mechanical nonlinearity remain insufficiently understood, and this impedes their further advancements. This holistic review addresses these standalone concepts and bridges the gaps by providing a thorough examination of their myriad fabrication techniques, applications, and experimental, and modeling approaches. Specifically, the review presents a wide spectrum of fabrication techniques, ranging from traditional molding to cutting-edge four-dimensional (4D) printing, and their unbounded prospects in diverse fields of research. The review covers various modeling approaches, including continuum mechanical frameworks encompassing phenomenological and homogenization models, as well as microstructural models. Additionally, it addresses emerging techniques like machine learning-based modeling in the context of hMSMs. Finally, the expansive landscape of these promising material systems is provided for a better understanding and prospective research.

“…Magnetic robots with good reconfigurability and programmability, including (quasi-)spherical robots, helical robots, flexible robots, wirelike robots, and biohybrid robots, are a class of magnetic carriers at the nanometer to micron level that have attracted much attention in recent years and have unique advantages over conventional MNPs [ 34 ]. Drive sources for magnetic robots include magnetic fields [ 35 ], light [ 36 ], and sound [ 37 ]. Different types of magnetic robots have different structures.…”

Magnetic Drug Targeting (MDT) is of particular interest to researchers because of its good loading efficiency, targeting accuracy, and versatile use in vivo. Cardiovascular Disease (CVD) is a global chronic disease with a high mortality rate, and the development of more precise and effective treatments is imminent. A growing number of studies have begun to explore the feasibility of MDT in CVD, but an up-to-date systematic summary is still lacking. This review discusses the current research status of MDT from guiding magnetic fields, magnetic nanocarriers, delivery channels, drug release control, and safety assessment. The current application status of MDT in CVD is also critically introduced. On this basis, new insights into the existing problems and future optimization directions of MDT are further highlighted.
