Gill inspired hierarchical wrinkles of reduced graphene oxide encapsulated carbon nanotubes with significantly boosted supercapacitor performance

Thinking green with 2-D and 3-D MXenes: Environment friendly synthesis and industrial scale applications and global impact

“…This trend indicates high electrostatic repulsion between MXene layers and can be further analysed to evaluate surface chemistry and adsorption mechanisms. Ultrathin Ti 3 C 2 T x are reported to follow the Donnan effect (rejection of negatively charged impurities is high) where for a wide range of pH (3)(4)(5)(6)(7)(8)(9)(10) it exhibits a negative zeta potential whereas the HF-Ti 3 C 2 T x exhibit positive surface charge at low pH [119]. Zeta potential can be further studied to understand time dependent surface charge transitions [136].…”

“…Last two decades have been witness to the performance of versatile two dimensional (2D) materials and their gradual adoption in the energy sector owing to their excellent conductivity, high capacitance and molecular architecture [1][2][3]. However, the primary concern with artificial energy harvesters is their inability to control energy dissipation in the form of thermal energy, followed by cyclic instability and industry scale production [4][5][6][7][8]. Despite this, their ordered orientation, refined architectures and the complete transformation in molecular dynamics has motivated researchers to fine-tune existing material properties and search for new materials that offer higher stability and scalable performance [9].…”

Hierarchically spring nanofibrous and wrinkled-structured electrode for highly comfortable wearable triboelectric nanogenerators

“…Additionally, it provides a remarkably uniform and smooth lm surface, which is difficult to achieve with carbon nanotubes, metal nanowires, or metallic grids. [44][45][46] To increase the surface roughness of the lms, researchers fabricated hierarchical wrinkles with micro-and macrostructure on the triboelectric layers and electrodes, 15,17,18,[47][48][49][50][51][52][53][54][55][56][57] so the stretchability and electrication effect of TENGs with this structure can be improved signicantly. 17 For instance, Qi et al 17 synthesized a stretchable TENG based on hierarchically micro-wrinkled electrospun PA6 membranes, which were fabricated during the balloon-blowing method.…”

Corrugated Cobalt Titanate/Partially Reduced Graphene Oxide Heterojunctions for a Selective Isopentanol Gas Sensor

“…These lattice defects are considered as active sites for adsorption or sensing reactions, playing an important role in improving the selectivity. 19 At present, prGO can be prepared by chemical vapor deposition, 20 thermal reduction, 21 chemical reduction, 22 hydrothermal methods, 23 and so on. However, until now, it is difficult to precisely control the morphology and surface chemistry of prGO.…”
