“…Among various pseudosupercapacitor materials, TiO 2 has received exceptional interest because of their low cost, excellent chemical stability, abundance and low environmental impact [18]. However, the semiconducting nature and poor electrical conductivity of TiO 2 attributes to the lower electrochemical activity thereby reducing its specific capacitance (< 50 F g −1 ) [19]. Many efforts have been focused to overcome these issues such as developing TiO 2 architectures (nanotube arrays) with sufficient open structures thereby providing a direct pathway for charge transport to…”

“…Further, it has also been suggested that ECM-mimicking surfaces can augment metabolic and osteogenic functions . Our ZrO 2 NG surfaces are an interconnected nanowire-like architecture that can influence the activity of key cells such as osteoblasts and fibroblasts. , Compared with other nanostructures, NG is more randomly organized but has larger surface area. − Interestingly, various studies have explored the use of NG for electronic applications but not toward biomedical uses (enhanced cell bioactivity). − Indeed, the potential of NG is yet to be explored in the field of dentistry/orthopedics for the enhancement of implant integration.…”

Zirconium has achieved popularity as a biomaterial for dental and orthopedic implants; however, its bioinertness can compromise implant-tissue integration, especially in compromised patient conditions. More recently, various nanoengineering strategies have been explored to enhance the bioactivity of Ti-based implants; however, nanoengineering of Zr-based implants has not been adequately explored. In this pioneering attempt, we report on the optimized fabrication of various nanostructures on microrough Zr surfaces and explore the influence of the underlying surface topography. In-depth optimization of electrochemical anodization (EA) is performed by tuning various parameters, including substrate topography, voltage/current and time, onto microrough (micromachined) and extremely rough Zr substrates, which represent clinically relevant implant surfaces. Variations of EA factors yielded various nanotopographies, including nanotubes, nanograss and nanotemplates, offering different topographical and chemical combinations. EA optimization and precise current–voltage recording was performed to arrive at clinically translatable and reproducible nanostructures on Zr surfaces. This study will pave the way toward the fabrication of the next generation of nanoengineered Zr-based orthopedic and dental implants.

“…The electrolyte used for the analysis was 1, 3, and 6 M KOH. The CV curves were recorded at different scan rates (3,5,10,20,30,40, and 50 mV/s) within a specific potential window for both the three-electrode system and the ASC device. The GCD analysis was performed at different current densities ranging from 0.5 to 10 A g −1 .…”

Ternary nanocomposites synergistically combine the material characteristics of three materials, altering the desired charge storage properties such as electrical conductivity, redox states, and surface area. Therefore, to improve the energy synergistic of SnO2, TiO2, and three-dimensional graphene, herein, we report a facile hydrothermal technique to synthesize a ternary nanocomposite of three-dimensional graphene–tin oxide–titanium dioxide (3DG–SnO2–TiO2). The synthesized ternary nanocomposite was characterized using material characterization techniques such as XRD, Raman spectroscopy, FTIR spectroscopy, FESEM, and EDXS. The surface area and porosity of the material were studied using Brunauer–Emmett–Teller (BET) studies. XRD studies showed the crystalline nature of the characteristic peaks of the individual materials, and FESEM studies revealed the deposition of SnO2–TiO2 on 3DG. The BET results show that incorporating 3DG into the SnO2–TiO2 binary nanocomposite increased its surface area compared to the binary composite. A three-electrode system compared the electrochemical performances of both the binary and ternary composites as a battery-type supercapacitor electrode in different molar KOH (1, 3, and 6 M) electrolytes. It was determined that the ternary nanocomposite electrode in 6 M KOH delivered a maximum specific capacitance of 232.7 C g–1 at 1 A g–1. An asymmetric supercapacitor (ASC) was fabricated based on 3DG–SnO2–TiO2 as a positive electrode and commercial activated carbon as a negative electrode (3DG–SnO2–TiO2//AC). The ASC delivered a maximum energy density of 28.6 Wh kg–1 at a power density of 367.7 W kg–1. Furthermore, the device delivered a superior cycling stability of ∼97% after 5000 cycles, showing its prospects as a commercial ASC electrode.
