“…The crystal phases of Al (111), Al (200), Al (220) and Al (311) were observed at diffraction angle 38.45°, 44.69°, 65.04°and 78.15°respectively. The results have been found consistent with the literature [23,24]. The above-mentioned xray diffraction peaks of Al can be utilized to assure the fabrication of the Al-TiC composites with the existence of an appropriate crystal phase of Al and TiC.…”

With numerous reinforcements, aluminum and its alloys are finding growing applications in every sector of industry. Titanium carbide (TiC) is regarded as an outstanding reinforcing material as compared to widely used carbide particles because of its excellent physical and mechanical characteristics, as well as its especially good interfacial bonding (wetting) capacity with aluminum. In the present research work, the effect of the mixing time of the matrix and reinforcement powders has been investigated on the crystallite size and lattice strain of the AA7075–5 wt.% TiC composites. The mechanical properties of the developed composites were also investigated in terms of microhardness values. X‐ray diffraction and scanning electron microscopy (SEM), transmission electron microscopy (TEM), particles size distribution analysis and x‐ray energy dispersive spectroscopy (EDS) of the synthesized powder samples were done to see the effect of mixing time on their microstructures. The increase in mixing time led to a homogeneous distribution of 5 wt.% of TiC particles, a decrease in particles clustering. The considerable grain refining was confirmed, which reflected a reduction in particle size originating from a prolonged mixing time. The significant improvement in the crystallite size and microhardness of the produced composites were achieved with increasing mixing time.

“…The reverse trend is observed in BJH average pore size of the support after active metal impregnation, Table 1. However, the overall Brunauer-Emmett-Teller surface area of the bimetallic oxide support decreased to 96.1 m 2 /g from 125 m 2 /g as in the case of alumina support, these results are in agreement with the literature [20,23].…”

“…The precipitate formed is washed and filtered then with demineralized water. The slurry obtained was dried at 110 °C for 12 hours and further calcined at 850 °C for 4 h in furnace under static air (ramping rate of 5 °C/min), for alumina-magnesia support material [19,20]. Initially, different catalysts containing 10 wt.% nickel on monometallic alumina support (Ni Ref ) and bimetallic support with alumina: magnesia ratio 2 : 1 (Ni a ), 1 : 1 (Ni b ), 1 : 2 (Ni c ) have been prepared.…”

Nickel supported on alumina‐magnesia bimetallic oxide support (Ni/Al2O3‐MgO) nano‐catalysts were prepared by the co‐precipitation followed by impregnation (two steps) method separately and tested for the dry methane reforming. The optimum bimetallic oxide catalyst support ratio (i. e., alumina: magnesia) is tested and it has been found that alumina:magnesia ratio of 1 : 2 showed the most stable results. The effect of nickel loading has been studied by impregnating the bimetallic oxide support with nickel as 10 wt.%, 12 wt.%, 14 wt.%, and 16 wt.%. It has been found that the catalyst containing 12 wt.% nickel showed the best activity in terms of methane (CH4) and carbon dioxide (CO2) percentage conversions, syngas (H2:CO) ratio, lowest coke formation and stability for dry methane reforming at 800 °C, 1 atm and methane: carbon dioxide ratio of unity. The Brunauer‐Emmett‐Teller surface area and pore size analysis of fresh catalyst has been carried out. The x‐ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, energy dispersive x‐ray and elemental mapping analysis for fresh and spent catalysts has been obtained confirming the coke formation during the reaction.

“…On the other hand, piezoelectric sensing has been proposed as a viable option for developing a new self-powered generation pressure sensor with the performance of exceptional. Piezoelectric nanomaterials having remarkable piezoelectric and mechanical characteristics, like ZnO nanowires and flexible electrospun nanofibers of PVDF-TrFE, have been employed to make piezoelectric pressure sensors at various periods [112,113].…”

Wearable electronics are gaining widespread attention because of the potential applications of them in systems of wearable human care and health monitoring. These new devices are probably a collection of different applications like batteries, sensors, displays, and so on. In these respects, conductive fibers, inks, and fabrics were examined. On the field, three materials categories including carbon, metal, and polymer-based materials were investigated. Materials of carbon have advantages like good electrical conductivity, structural and inherent flexibility, high thermal and chemical stability, light weight, ease of chemical operation, and potential production of mass, enabling them to be a good candidate for wearable and flexible electronics. Conducting polymers have a number of drawbacks in their natural state; however, by combining them with other materials, these drawbacks can be solved. Conducting polymer composites have a wide range of applications in optoelectronic, electronic, and electrical sectors due to their synergetic effects. Liquid metal was bestowed with new-emerging characteristics and multifunctional applications. Due to the high surface tension and limited adherence on many surfaces, the manufacturing approach of patterning liquid metals on flexible substrates has received a lot of attention up to now.The current state of wearable materials as actuators and fabrication processes are discussed in this review paper.
