“…Shaped pulse material ablation and micromachining can be used to treat the surfaces of warships and planes, to achieve corrosion protection, or strong radar wave absorption. Nanometer and micrometer sized structures on the surface can be tuned to increase the absorption of light and radar wave [225,261,262]. Changing the shape of the laser field has a big influence on the morphology of the irradiated area [208,[263][264][265][266].…”

This review focuses on the properties of the light fields that are more useful in applications. We review recent means of generating shaped-pulse light field, by which matters can be steered toward the desired products, thereby allowing the coherent control in terms of effectiveness, selectivity and manipulation. Applications of these light fields are discussed, including bioscience, laser machining, novel material fabrication, trace material detection and military.

“…Porous silicon carbide (SiC) ceramics have attracted attention not only in the academic field but also industrially due to their remarkable characteristics such as low bulk density, high melting point, high oxidation resistance, bio-inert characteristic, corrosion resistance, high chemical stability, excellent mechanical strength, high specific strength, high thermal shock resistance, tailored thermal conductivity, and controlled permeability. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] These characteristics have made porous SiC ceramics suitable candidates to perform a wide range of engineering applications including membranes for water purification and gas separation, 1,3,5,11,[16][17][18][19] ceramic carriers, 20 lightweight structural materials, 4,6,7,9 hot gas filters, 10,11,[21][22][23][24][25] catalytic supports, [26][27][28] and thermal insulators.

The effects of SiC whisker addition into nano‐SiC powder‐carbon black template mixture on flexural strength, thermal conductivity, and specific flow rate of porous silica‐bonded SiC ceramics were investigated. The flexural strength of 1200°C‐sintered porous silica‐bonded SiC ceramics increased from 9.5 MPa to 12.8 MPa with the addition of 33 wt% SiC whisker because the SiC whiskers acted as a reinforcement in porous silica‐bonded SiC ceramics. The thermal conductivity of 1200°C‐sintered porous silica‐bonded SiC ceramics monotonically increased from 0.360 Wm–1K–1 to 1.415 Wm–1K–1 as the SiC whisker content increased from 0 to 100 wt% because of the easy heat conduction path provided by SiC whiskers with a high aspect ratio. The specific flow rate of 1200°C‐sintered porous SiC ceramics increased by two orders of magnitude as the SiC whisker content increased from 0 to 100 wt%. These results were primarily attributed to an increase in pore size from 125 nm to 565 nm and secondarily an increase in porosity from 49.9% to 63.6%. In summary, the addition of 33 wt% SiC whisker increased the flexural strength, thermal conductivity, and specific flow rate of porous silica‐bonded SiC ceramics by 35%, 133%, and 266%, respectively.

“…The popularization and fast development of military aviation radar applications and electronic/electrical devices greatly increased the presence of electromagnetic radiation and electromagnetic pollution. Therefore, microwave absorbing materials such as carbon fiber felt – multi-walled carbon nanotubes/epoxy composites (Singh et al , 2014), BaFe 11 Mg 2+ 0.25 X 2+ 0.25 Ti 4+ 0.25 O 19 ( X 2+ =Cu, Mn, Zn, Ni and Co) nanoparticles (Sözeri et al , 2016), graphene oxide/polyvinyl alcohol/carbonyl iron powder composites (Qi et al , 2019), SiC nanowires (Shen et al , 2020) molybdenum dioxide (Wang et al , 2020), hexagonal boron nitride nanosheet/carbon nanotube composites have been developed to reduce this pollution by various loss mechanisms (Zhong et al , 2018). Lately, nanomaterials have been a popular subject of study in the world of science due to their unique effects (Tan et al , 2017; Duan et al , 2019; Wang et al , 2018; Özkan et al , 2020).…”

Purpose The purpose of this paper is to investigate the effect of doping element on the microwave absorption performance of hexagonal nano boron nitride (h-nBN)-reinforced basalt fabric (BF)/epoxy composites. A new type of hybrid composite that will be produced by the use of boron nitride as an additive that leads to increased radar absorption capability will be developed and a new material that can be used in aeronautical radar applications. Design/methodology/approach This study is focused on the microwave absorption properties of h-nBN doped basalt fabric-reinforced epoxy composites. Basalt fabric (BF)/epoxy composites (pure composites) and the BF/h-nBN (1 Wt.% h-nBN doped composites) hybrid composites were fabricated by vacuum infusion method. Phase identification of the composites were performed using X-ray diffraction (XRD), the 2θ scan range was from 10 to 60 with the scanning speed of 3°/min and surface morphologies of the composites were investigated using scanning electron microscopy (SEM). Microwave properties of samples were investigated through transmission/reflection measurements in Agilent brand 2-Port PNA-L Network Analyzer in the frequency range of 3–18 GHz. The prepared sample is positioned between two horn antennas with and without metal plate. Findings Experimental results show that h-nBN doped composite was synthesized successfully and the produced hexagonal nano boron nitride-added fiber laminated composite material has good absorption behavior when they are used with metallic sheets and good for isolation applications at many points in the 3–18 GHz band. Originality/value This paper will contribute to the literature on the use of basalt fabric, which are new types of fibers, and hexagonal nano boron nitride and the effects of boron nitride on radar absorption properties of composite material. It presents detail characterization of each composite by using XRD and scanning electron microscopy.
