“…Flexible electronics have been applied to various fields, such as displays, sensors and medical appliances. Ag nanomaterials are commonly used to fabricate flexible electronics due to their high conductivity and mechanical flexibility 58 – 60 . Here, Ag nano-particles (NPs) are prepared in situ by conducting the silver mirror reaction.…”

Anisotropic functional patterned surfaces have shown significant applications in microfluidics, biomedicine and optoelectronics. However, surface patterning relies heavily on high-end apparatuses and expensive moulds/masks and photoresists. Decomposition behaviors of polymers have been widely studied in material science, but as-created chemical and physical structural changes have been rarely considered as an opportunity for wettability manipulation. Here, a facile mask-free confined-etching strategy is reported for intrinsic wettable surface patterning. With printing technology, the surface wetting state is regulated, enabling the chemical etching of setting locations and efficient fabrication of complex patterns. Notably, the created anisotropic patterns can be used for realizing water-responsive information storage and encryption as well as fabricating flexible electrodes. Featuring advantages of simple operation and economic friendliness, this patterning approach brings a bright prospect in developing functional materials with versatile applications.

“…As a result, the microbial fuel cell's efficiency improves. Graphene, carbon nanotubes, and graphitic carbon nitride have comprehensive performance on opteoelectronics, according to its tremendous physicochemical, mechanical properties, also its high electrical and thermal conductivities are used in many electronic applications [20][21][22]. Furthermore, it is hypothesized that the nanomaterials will improve the biofilm development process on the electrode surface.…”

Microbial fuel cells (MFCs) are devices where bacteria generate electrical energy by oxidizing organic matter in wastewater. The implementation of MFCs on a commercial scale is limited due to electrode resistances, which are one of the key factors limiting electricity generation. This study presents a method to maximize the electrical power production from MFCs by coating the electrodes using nanomaterials which leads to prototyping novel electrodes having higher electrical conductivity than common electrodes. The voltage reached 1.234 V directly after operating the MFCs, with nanocoated electrodes, and showed voltage stability till the end of the 140 h interval with a peak value of 1.367 V with a maximum areal power density of 116 mW m−2 and a maximum volumetric power density of 15.6 mW m−3. However, the voltage of the control (without coating) was steadily increased to 0.616 V after 22 h with a maximum areal power density of 23.6 mW m−2 and a maximum volumetric power density of 3.2 mW m−3 then showed voltage stability till the end of the 140 h interval. It was found that the coulombic efficiency of the MFCs where its electrodes are coated with graphitic carbon nitride nanosheets was higher than graphene, carbon nanotubes, and the control in a descending order, respectively. By this method, it is possible to improve the electrical conductivity of the MFCs which results in increasing the generated electrical power by 4.9 times the conventional method.
