“…They are often derived using polysiloxane, polycarbosilane, and polysilazane. It is worth noting that among the ternary ceramics, SiOC is extremely popular due to its strong oxidation and corrosion resistance ability [106,107]. It has appreciable chemical stability, and thermal durability too [104,108,109].…”

Conversion of inorganic-organic frameworks (ceramic precursors and ceramic-polymer mixtures) into solid mass ceramic structures based on photopolymerization process is currently receiving plentiful attention in the field of additive manufacturing (3D printing). Various techniques (e.g., stereolithography, digital light processing, and two-photon polymerization) that are compatible with this strategy have so far been widely investigated. This is due to their cost-viability, flexibility, and ability to design and manufacture complex geometric structures. Different platforms related to these techniques have been developed too, in order to meet up with modern technology demand. Most relevant to this review are the challenges faced by the researchers in using these 3D printing techniques for the fabrication of ceramic structures. These challenges often range from shape shrinkage, mass loss, poor densification, cracking, weak mechanical performance to undesirable surface roughness of the final ceramic structures. This is due to the brittle nature of ceramic materials. Based on the summary and discussion on the current progress of material-technique correlation available, here we show the significance of material composition and printing processes in addressing these challenges. The use of appropriate solid loading, solvent, and preceramic polymers in forming slurries is suggested as steps in the right direction. Techniques are indicated as another factor playing vital roles and their selection and development are suggested as plausible ways to remove these barriers.

“…One alternative approach to deal with this issue is the use of polymer-derived ceramics [13], which are converted into ceramics without the addition of ceramic particles [31,[345][346][347][348][349]. It proved capable of manufacturing SiOC [346,347,[350][351][352], SiC [350], SiCN [350,353], and SiBCN [348] by ceramic vat photopolymerization. This AM technology is relatively expensive [5].…”

Ceramic additive manufacturing allows the fabrication of small series of complex parts without the high costs of molds usually associated with traditional ceramic processing. Although research into ceramic 3D printing by all technologies started back in the 90s, its industrial application is still quite restricted when compared to polymers and metals, which is related to the limited availability and costs of equipment and materials for such applications. This review examined the advantages and limitations of each process (binder jetting, direct ink writing, directed energy deposition, fused deposition, material jetting, selective laser sintering, selective laser melting, and vat photopolymerization), discussing their particularities. It also summarized the commercially available 3D printers and raw materials for ceramic processing, pointing out to trends and challenges of each technology.

“…After that, many researchers began to deliberate on the theory and the fabrication of invisibility cloaks from the perspective of transformation optics, like carpet cloaks, [ 41–46 ] non‐Euclidean cloaks, [ 94 ] space‐time invisibility cloaks, [ 95–97 ] ray‐optics cloaks, [ 98–100 ] and conformal cloaks. [ 101–104 ] There are several reviews about invisibility and metamaterials, [ 73,75 ] which is helpful to understand their history and future.…”

Based on the form‐invariance of Maxwell's equations under coordinate transformations, mathematically smooth deformation of space can be physically equivalent to inhomogeneous and anisotropic electromagnetic (EM) medium (called a transformation medium). It provides a geometric recipe to control EM waves at will. A series of examples of achieving transformation media by artificially structured units from conventional materials is summarized here. Such concepts are firstly implemented for EM waves, and then extended to other wave dynamics, such as elastic waves, acoustic waves, surface water waves, and even stationary fields. These shall be cataloged as transformation metamaterials. In addition, it might be conceptually attractive and practically useful to control diverse waves for multi‐physics designs.
