The technique involves 3D printing short carbon fiber-reinforced polyamide 6 onto sandblasted 64Ti substrates, heated via a hot plate integrated into the 3D printer. Lap-shear tests reveal that adhesion strength improves with increased fusion time, achieving a maximum shear stress of 27.3 ± 2.2 MPa for 60 min welding.

Since then, the class of ingredients has widened to include metal/metal mixtures and with the progress in physical vapor deposition, precise nanoscale layering of the reactant has become possible. These reactive multilayer systems (RMS), comprising up to several hundred repetitions of individual layers, reach total film thicknesses of up to several tens of micrometers. The characteristic of these films is their capability of undergoing self-propagating exothermic reactions at up to ≈100 m/s and 2000 °C and more. Thermodynamics, reaction kinetics as well as thermal and chemical diffusion set the boundary conditions defining the reaction properties, thus providing means for reaction design.&lt;/p&gt;&lt;p&gt;The application of such self-propagating reactions is of great technological interest, e.g. for the joining of electronic components in electronics, the debonding of parts or even a repair of failure parts. However, the self-propagating reaction after multilayer ignition is hard to control in real technical systems. While the influence of the most prominent parameter, the bilayer thickness, has been studied extensively for various material combinations, many open questions exist regarding the effect of factors like surfaces, materials properties, roughness, morphology, thermo-mechanical stress, structuring or combined systems.&lt;/p&gt;&lt;p&gt;This special issue contains the latest research on such reactive multilayer systems based on Ni/Al and Ru/Al, the current understanding and their applications. The articles investigate the impact of the morphological characteristics and physical properties of the joining partners on the microstructural features of the fabricated RMS, as well as the role of thermophysical properties of the system and the kinetics of the reaction. The vision is the design of a “suitable” microjoining process with fitting electrical and thermal properties of a high-quality mechanical joining &lt;b&gt;Figure&lt;/b&gt; 1.&lt;/p&gt;&lt;p&gt;Means to manipulate and tailor the reaction are explored for both improving the understanding of fundamental mechanisms as well as for application on a system level. Different approaches for multilayer modification by substrate patterning are investigated, i.e. photolithography, deep etching and direct laser interference patterning. The resulting structure shows more or less strong deviations from the well-known planar multilayer structure when depositing on flat substrates, like curved layers, pores and discontinuities, which unfold their effect on the scale of up to a few bilayers. Their effects on the self-propagating reactions are discussed with respect to thermal and chemical diffusivity and interface mixing.

The ionic liquids-based FSR consists of a bandpass-type frequency-selective surface, a 3D resin container, and an ionic liquid layer. Numerical simulation analysis demonstrates that the transmission loss of the FSR is less than 3 dB within the range of 4.3–5.3 GHz, and the absorption rate exceeds 90% within the range of 8–27.5 GHz. The FSR exhibits reconfigurable characteristics: when the cavity is filled with the ionic liquid [EMIm][N(CN)₂], it demonstrates low-frequency transmission and high-frequency absorption. In contrast, when no ionic liquid [EMIm][N(CN)₂] is in the cavity, it exhibits low-frequency transmission. The proposed ionic liquids-based FSR also has a wide incidence angle with polarization-insensitive characteristics. By studying the electromagnetic characteristics of frequency-selective rasorbers at different temperatures, it is found that the frequency-selective rasorber has a stable passband at low frequencies and the absorption bandwidth decreases with increasing temperature at high frequencies.
