Sustainable Nanomaterials for Biomedical Applications

“…Advances in nanotechnological fabrication approaches have accelerated the discovery of new functional nanomaterials in tunable sizes, morphologies, and composition from non-renewable resources [ 18 , 19 , 20 , 21 ]. Such nanomaterials show superior physical and chemical properties compared to their bulk counterpart, making them beneficial to solve societal problems from health to renewable energy, information technology, and the environment [ 22 , 23 , 24 , 25 , 26 ]. However, the long-term commercial viability of these nanomaterials is posing a risk due to their reliance on non-renewable resources and highly energy-intensive manufacturing processes.…”

Titanium dioxide nanostructures doped with nickel and its performance in photocatalytic reduction of 4‐nitrophenol

“…To date, the design of onedimensional (1D) nanostructures such as nanotubes, nanowires, and nanorods with controllable features at the nanoscale has gained significant scientific interest in different areas such as optoelectronics, energy, catalysis, and medicine. 2 Among the advantageous characteristics provided by modifying the shape and size, the large surface-to-volume ratio and good ionic exchange capacity stand out, making the study of such modifications attractive. 3 In addition to this, some investigations have shown that tubular nanostructured TiO 2 exhibits better photocatalytic activity than its nano-powder form.…”

Ultrahigh-Temperature-Tolerant NiO@Ag NW-Based Transparent Heater with High Stability, Durability, Ultraflexibility, and Quick Thermal Response

“…In addition, Cu NWs have great advantages in terms of cost, but the oxidation problem deteriorates the stability at high temperatures, while Ag NWs have a bit better oxidation stability; thus, Ag NW-based FTHs are attracting greater attention as FTHs. 1,27 Due to these advantages, Ag NWs have been applied in various energy device fields including flexible fuel cells, 28−30 stretchable and transparent supercapacitors, 31,32 transparent sensors, 33−35 transparent wearable electronics, 36,37 T h i s c o n t e n t i s and air filters. 38,39 However, the dissatisfactory stabilities of Ag NWs including Rayleigh instability, chemical instability, oxidizability in an ambient atmosphere, and delamination phenomenon under mechanical tests limit the practical applications in FTHs.…”

“…Our group prepared NiO-encapsulated Ag NWs (NiO@Ag NWs) with enhanced thermal and chemical stabilities via solution-grown technology; the NiO thin shells can effectively prevent the contact between Ag NWs and the atmosphere. 37 Thus, it is a good candidate for fabrication of FTHs. In this work, NiO@Ag core−shell nanowires (NiO@Ag NWs) are prepared via solution processes.…”

“…Carbon-based FTHs possess excellent thermal conductivity and flexibility. , Unfortunately, CNTs and graphene are usually fabricated by chemical vapor deposition, and expensive equipment and a complex preparation process increase their preparation cost. , Moreover, the unsatisfactory conductivity of these carbon-based materials requires either high voltage or low transparency, or both, for achieving good heating performance. , Metal NWs (Cu NWs and Ag NWs) have been utilized to develop the FTHs due to their low resistance, high transmittance, and excellent mechanical flexibility. ,, One of the most notable progresses in the FTHs from metal nanowires is stretchable transparent heaters, which further broaden the application range of the FTHs. − Compared with Cu NW-based FTHs, Ag NW-based FTHs exhibit better optical and heating performances. In addition, Cu NWs have great advantages in terms of cost, but the oxidation problem deteriorates the stability at high temperatures, while Ag NWs have a bit better oxidation stability; thus, Ag NW-based FTHs are attracting greater attention as FTHs. , Due to these advantages, Ag NWs have been applied in various energy device fields including flexible fuel cells, − stretchable and transparent supercapacitors, , transparent sensors, − transparent wearable electronics, , and air filters. , However, the dissatisfactory stabilities of Ag NWs including Rayleigh instability, chemical instability, oxidizability in an ambient atmosphere, and delamination phenomenon under mechanical tests limit the practical applications in FTHs. − …”
