The inability of membranes to handle a wide spectrum pollutants is an important unsolved problem for water treatment. Here we demonstrate desalination via membrane distillation process using graphene where permeation enabled by nanochannels multilayer, mismatched, partially overlapping grains. Graphene films derived from renewable oil exhibit significantly superior retention vapour flux and salt rejection rates, antifouling capability under mixture saline containing contaminants such as oils...
Solid-state supercapacitors can be fabricated by uniformly coating RuO<sub>2</sub>onto vertical graphene (VG) using a simple, scalable, low-cost and solution-free method. The binder-free RuO<sub>2</sub>/VG hybrid electrodes possess high areal capacitance, low electrical resistance, good frequency response, excellent stability, shedding light on the commercialisation of Ru-based energy storage devices.
Abstract Thermal chemical vapour deposition techniques for graphene fabrication, while promising, are thus far limited by resource-consuming and energy-intensive principles. In particular, purified gases extensive vacuum processing necessary creating a highly controlled environment, isolated from ambient air, to enable the growth of films. Here we exploit ambient-air environment films, without need compressed gases. A renewable natural precursor, soybean oil, is transformed into continuous...
Hybrid nanostructures composed of vertical graphene nanosheet (VGNS) and MoS2 nano-leaves are synthesized by the chemical vapor deposition method followed a solvothermal process. The unique three-dimensional MoS2/VGNS arranged in vertically aligned manner can be easily constructed on various substrates, including Ni foam graphite paper. Compared with MoS2/carbon black, nanocomposites grown exhibit enhanced electrochemical performance as anode material lithium-ion batteries, delivering...
Abstract A key to sustainable management of saline organic-rich wastewaters is precisely fractionate organic components and inorganic salts (NaCl) as individual resources. Conventional nanofiltration electrodialysis processes suffer from membrane fouling compromise the fractionation efficacy. Here we develop a thin-film composite nanoporous via co-deposition dopamine polyethyleneimine highly anion-conducting membrane. Experimental results molecular dynamics simulations show that effectively...
Plasmas, the 4th state of matter, uniformly transform natural precursors with different chemical composition in solid, liquid, and gas states into same functional vertical graphenes a single-step process within few minutes. Functional show reliable biosensing properties, strong binding proteins, improved adhesion to substrates. As service our authors readers, this journal provides supporting information supplied by authors. Such materials are peer reviewed may be re-organized for online...
Abstract Graphene and carbon nanotubes (CNTs) are attractive electrode materials for supercapacitors. However, challenges such as the substrate‐limited growth of CNTs, nanotube bundling in liquid electrolytes, under‐utilized basal planes, stacking graphene sheets have so far impeded their widespread application. Here we present a hybrid structure formed by direct CNTs onto vertical nanosheets (VGNS). VGNS fabricated green plasma‐assisted method to break down reconstruct natural precursor...
Herein, we reveal that the cytotoxicity mechanism of graphene oxide is synergy between membrane and oxidative stress towards biofilm forming bacteria.

Abstract Reconfigurable terahertz electronics devices with high tuneability are pivotal for next-generation speed wireless communication and sensing technologies. Significant challenges exist realizing these devices, particularly on the design of smart metastructures that can manipulate electromagnetic radiation at frequencies fabrication effective reconfigurability.
