“…3D printing of highly pure copper with superior electrical and thermal properties has been studied extensively due to its broad potential in many applications including electronic devices [1,[12][13][14][15][16][17][18][19][20], thermal management systems [4,12], and the aerospace industry [4,12,[21][22][23][24][25]. Compared to conventional 3D printing of highly pure copper with superior electrical and thermal properties has been studied extensively due to its broad potential in many applications including electronic devices [1,[12][13][14][15][16][17][18][19][20], thermal management systems [4,12], and the aerospace industry [4,12,[21][22][23][24][25]. Compared to conventional fabrication methods such as metal casting, welding, and machining, 3D printing can fabricate more optimized and complex 3D copper parts without using additional tools [26][27][28][29][30][31]…”

Copper has been widely used in many applications due to its outstanding properties such as malleability, high corrosion resistance, and excellent electrical and thermal conductivities. While 3D printing can offer many advantages from layer-by-layer fabrication, the 3D printing of highly pure copper is still challenging due to the thermal issues caused by copper’s high conductivity. This paper presents a comprehensive review of recent work on 3D printing technology of highly pure copper over the past few years. The advantages and current issues of 3D printing methods are compared while different properties of copper parts printed by these methods are summarized. Finally, we provide several potential applications of the 3D printed copper parts and an overview of current developments that could lead to new improvements in this advanced manufacturing field.

“…The global composite materials market is expected to reach an estimated $39.1 billion by 2022. 15 The growing interest in stronger, lighter and more fuel-efficient products from the transportation vehicle industry (both the private sector and military) has led to an increased demand for graphene materials. 16 However, currently available commercial graphene materials are expensive, signicantly slowing down their potential usage in these applications demanding a high volume of graphene materials.…”

A novel process is developed for high-volume production of low-cost graphene materials from any solid carbon resources, especially biomass sources. Few-layer graphene materials from solid carbon resources are produced through a molecular cracking and welding (MCW) method. The MCW technique is a single step process with two stages, i.e., graphene-encapsulated core-shell nanoparticles are first formed by catalytic thermal treatment of solid carbon materials. Then in the second stage these core-shell structures are opened by 'cracking molecules', and the cracked graphene shells are self-welded and reconstructed to form high quality multilayer graphene materials at a heating temperature with selected welding reagent gases. This novel graphene material with super hydrophobic properties can be used to filter water from crude oil emulsions in the petroleum industry.

“…Therefore, addition of CNT into the HA matrix can be a possible route attributed to their exceptional mechanical properties (Young’s modulus) and physical properties as well as good biocompatibility [ 25 , 26 ]. The CNT is also found to possess a hydrophobic nature (may be essential for protein and cell adsorption [ 23 ]) and are lightweight [ 27 ]. CNT-based composite materials exhibit biocompatibility without cytotoxicity as an important property for biomedical orthopedic and cardiovascular applications [ 28 ] due to its reported bioactivity [ 29 , 30 , 31 ].…”

Pertaining to real-life applications (by scaling up) of hydroxyapatite (HA)-based materials, herein is a study illustrating the role of carbon nanotube (CNT) reinforcement with ceria (CeO2) and silver (Ag) in HA on titanium alloy (TiAl6V4) substrate, utilizing the plasma-spraying processing technique, is presented. When compared with pure HA coating enhanced hardness (from 2.5 to 5.8 GPa), elastic modulus (from 110 to 171 GPa), and fracture toughness (from 0.7 to 2.2 MPa·m1/2) elicited a reduced wear rate from 55.3 × 10−5 mm3·N−1·m−1 to 2.1 × 10−5 mm3·N−1·m−1 in HA-CNT-CeO2-Ag. Besides, an order of magnitude lower Archard’s wear constant and a 41% decreased shear stress by for HA-CNT-CeO2-Ag coating depicted the effect of higher hardness and modulus of a material to control its wear phenomenon. Antibacterial property of 46% (bactericidal) is ascribed to Ag in addition to CNT-CeO2 in HA. Nonetheless, the composite coating also portrayed exaggerated L929 fibroblast cell growth (4.8 times more than HA), which was visualized as flat and elongated cells with multiple filopodial protrusions. Hence, synthesis of a material with enhanced mechanical integrity resulting in tribological resistance and cytocompatible efficacy was achieved, thereupon making HA-CNT-CeO2-Ag a scalable potent material for real-life load-bearing implantable bio-coating.
