“…Safaee and Chen prepared resin‐MNP nanocomposites (using isobornyl acrylate as a viscosity modifier) with ultra‐high spatial resolution by a magnetic stereolithography approach in which a conventional polymerization setup was equipped with a linear array of neodymium magnets with vertical steps in the magnet holder (to generate a field‐ and hence an MNP‐gradient), within a set of Helmholtz coils (to generate a uniform static‐field, which produces gradient‐free MNP alignment in the resin in the absence of the array). [ 61 ] MNP gradients (from 0 to 4 wt%) were achieved, typically with Young's modulus changing from 0.8 to 1.5 GPa along the gradient. The study, enabling preparation of materials with more predictable properties, establishes a framework for design and manufacture of functionally graded polymer nanocomposites.…”

Multifunctional nanocomposites which exhibit well‐defined physical properties and encode spatiotemporally‐controlled responses are emerging as components for advanced responsive systems. For biomedical applications magnetic nanocomposite materials have attracted significant attention due to their ability to respond to spatially and temporally varying magnetic fields. The current state‐of‐the‐art in development and fabrication of magnetic hydrogels toward biomedical applications is described. There is accelerating progress in the field due to advances in manufacturing capabilities. Three categories can be identified: i) Magnetic hydrogelation, DC magnetic fields are used during solidification/gelation for aligning particles; ii) additive manufacturing of magnetic materials, 3D printing technologies are used to develop spatially‐encoded magnetic properties, and more recently; iii) magnetic additive manufacturing, magnetic responses are applied during the printing process to develop increasingly complex structural arrangement that may recapitulate anisotropic tissue structure and function. The magnetic responsiveness of conventionally and additively manufactured magnetic hydrogels are described along with recent advances in soft magnetic robotics, and the categorization is related to final architecture and emergent properties. Future challenges and opportunities, including the anticipated role of combinatorial approaches in developing 4D‐responsive functional materials for tackling long‐standing problems in biomedicine including production of 3D‐specified responsive cell scaffolds are discussed.

Composites are two or more materials with different properties joined together to manufacture a new material. The resulting physical and chemical properties of each constituent new materials which remain distinct with enhanced properties when compared to the individual constituent materials.With this background, Photovoltaic cells (PV) are very important source of energy in recent years falling under Renewable Energy Resources (RES) meaning that it is abundant in nature, and also environmentally friendly in producing electricity. PV cells contains tiny different types of silicon layers which when the sun shines through it causes reaction between the electrons. In this way, the movement of the electrons through itself and around the circuit generate electricity. Subsequently, the solar cell keeps generating electricity as long as the sun is shining on it. A lot of research has been done and still on-gong on the enhancement of the PV cells to optimize their application. Therefore, the objective of this study is to review and compare the current state-of-the-art articles on different types of composites, which have been used for the PV cells enhancement, especially some twodimensional (2D) materials. Therefore, graphene and MoS used as nanocomposites are considered in this review to support appropriate and informed decisions that are made available to researchers and industries to know the best materials to use going forward in the manufacture of PV cells for better enhancement. Summary of these and more have been presented and prospected in this article.

Additive manufacturing (AM) also known as 3D printing (3DP) has become a popular technology with a wide range of applications, from which vat photopolymerization is a technique for producing nanocomposites with controlled mechanical, thermal, and electrical properties. This technology uses a UV light laser to cure a liquid resin into a solid object, layer by layer, allowing complex three-dimensional (3D) objects with intricate details of manufacturing and excellent finishing. Nanocomposites produced by vat photopolymerization have been used in aerospace, automotive, and medical industries, due to their superior mechanical strength and dimensional accuracy. In this article, we will discuss the advantages and other aspects of nanocomposites made with vat photopolymerization, exploring potential applications, and discuss the research by different areas, such as their AM technologies and materials properties. Graphical abstract This review deals with nanocomposites made by additive manufacturing (3D printing), presenting a systematic on vat photopolymerization technology, including the technologies, materials, and properties.
