“…[ 103 ] As a well‐known biodegradable metal, Mg is routinely found in structural implants and is the preferred choice as anode material in transient primary batteries due to its high theoretical specific charge capacity (2200 mAh g −1 ), high physiological tolerance (300 mg per day), biocompatibility, and appreciable negative electrode potential (−2.3 V vs standard hydrogen electrode). [ 49,99 ] Mg degrades in aqueous solution to produce hydrogen gas and magnesium hydroxide (Mg(OH) 2 ), a biocompatible corrosion product shown to enhance bone growth in vivo. [ 104 ] The degradation behavior of Mg is influenced by a variety of factors including the composition of degrading media, temperature, and the shape/form in which Mg is conformed in the batteries.…”

“…developed a Mg–Zn anode system for transient Mg primary batteries via combinatorial magnetron cosputtering. [ 99 ] The rationale behind their study was to identify the optimum combination in the Mg–Zn system that would provide higher electrochemical performance and longer lifetime. The corrosion resistance of Mg was found to be improved with increasing Zn concentration; however, no degradation experiments were reported in the paper.…”

“…[ 98 ] Typically used biodegradable metals in transient batteries include Mg, Mg‐based alloys, iron (Fe), molybdenum (Mo), zinc (Zn), and tungsten (W). [ 8,49,74,99 ] All these metals except W are essential metallic elements for the human body with significant physiological roles. Metal oxides such as MoO 3 and manganese dioxide (MnO 2 ) were applied as cathode materials for biodegradable batteries due to their high solubility in aqueous solution, biocompatibility at controlled levels, and edibility.…”

Transient technology seeks the development of materials, devices, or systems that undergo controlled degradation processes after a stable operation period, leaving behind harmless residues. To enable externally powered fully transient devices operating for longer periods compared to passive devices, transient batteries are needed. Albeit transient batteries are initially intended for biomedical applications, they represent an effective solution to circumvent the current contaminant leakage into the environment. Transient technology enables a more efficient recycling as it enhances material retrieval rates, limiting both human and environmental exposures to the hazardous pollutants present in conventional batteries. Little efforts are focused to catalog and understand the degradation characteristics of transient batteries. As the energy field is a property‐driven science, not only electrochemical performance but also their degradation behavior plays a pivotal role in defining the specific end‐use applications. The state‐of‐the‐art transient batteries are critically reviewed with special emphasis on the degradation mechanisms, transiency time, and biocompatibility of the released degradation products. The potential of transient batteries to change the current paradigm that considers batteries as harmful waste is highlighted. Overall, transient batteries are ready for takeoff and hold a promising future to be a frontrunner in the uptake of circular economy concepts.

“…Recently, the applications of graphene, graphene oxide (GO), and reduced graphene oxide (rGO) have increased in the biomedical areas such as cell differentiation and osteoblast growth. [3][4][5][6][7][8] As compared to graphene, the presence of oxygen-containing functional groups in GO has promoted a wider application of the latter in the field of surface chemistry. Structurally, GO consists of a single layer of graphene sheets where the concentration of carbon atoms is reduced to 40-60% due to the addition of oxygen-containing functional groups.…”

Introduction This paper presents a novel technique for the synthesis of graphene oxide (GO) with various surface features using high-density atmospheric plasma deposition. Furthermore, to investigate the use of hydrophobic, super-hydrophobic, and hydrophilic graphene in biological applications, we synthesized hydrophobic, super-hydrophobic, and hydrophilic graphene oxides by additional heat treatment and argon plasma treatment, respectively. In contrast to conventional fabrication procedures, reduced graphene oxide (rGO) formed under low pressure and high-temperature environment using a new synthesis method—developed and described in this study—offers a convenient deposition method on any kind surface with controlled wettability. Methods High density at atmospheric plasma is used for the synthesis of rGO and GO and its biocompatibility based on various wetting properties was evaluated using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, and the viability of cells in response to rGO and GO with various surface features was investigated. Structural integrity was characterized by Raman spectroscopy, FESEM and FE-TEM. Wettability was measured via contact angle method and confirmed with XPS analysis. Results We found that GO coating with a hydrophilic feature is more biocompatible than other surfaces as observed in case of fibroblast cells. We have shown that wettability—controlled by GO deposition—influences biocompatibilities and antibacterial effect of biomaterial surfaces. Discussion Measuring the contact angle, it is found that contact angle for hydrophobic is increased to 150.590 and reduced to 11.580 by heat and argon plasma treatment, respectively, from 75.880 that was initially in the case of hydrophobic surface. XPS analysis confirmed various oxygen-containing functional groups transforming as deposited hydrophobic surface into superhydrophobic and hydrophilic surface. Thus, we have proposed a new, direct, cost-effective, and highly productive method for the synthesis of rGO and GO—with various surface properties—for biological applications. Similarly, for the dental implant application, the Streptococcus mutans was used as an antibacterial effect and found that S. mutans grows slowly on hydrophilic surface. Thus, antibacterial effect was prominent on GO with hydrophilic surface.
