Health and environmental impacts of graphene-based materials need to be thoroughly evaluated before their potential applications. Graphene has strong cytotoxicity toward bacteria. To better understand its antimicrobial mechanism, we compared the antibacterial activity four types (graphite (Gt), graphite oxide (GtO), graphene (GO), reduced (rGO)) a bacterial model—Escherichia coli. Under similar concentration incubation conditions, GO dispersion shows highest activity, sequentially followed...
Graphene oxide (GO) is a promising precursor to produce graphene-family nanomaterials for various applications. Their potential health and environmental impacts need good understanding of their cellular interactions. Many factors may influence biological interactions with cells, the lateral dimension GO sheets one most relevant material properties. In this study, model bacterium, Escherichia coli ( E. ), was used evaluate antibacterial activity well-dispersed sheets, whose size differs by...
To further our understanding on the antibacterial activity of single-walled carbon nanotubes (SWCNTs), high purity SWCNTs with average diameter 0.83 nm and (7,5) chirality as dominate (n,m) structure were dispersed in a biocompatible surfactant solution. Ultraviolet−visible−near-infrared radiation absorption spectroscopy was employed to monitor aggregation SWCNTs. The results demonstrated that individually more toxic than SWCNT aggregates toward bacteria (gram-negative Escherichia coli,...
Mg-based materials are one of the most promising hydrogen storage candidates due to their high capacity, environmental benignity, and Clarke number characteristics. However, limited thermodynamics kinetic properties pose major challenges for engineering applications. Herein, we review recent progress in improving kinetics, with an emphasis on models influence various parameters calculated models. Subsequently, impact alloying, composite, nano-crystallization both dynamics discussed detail....
This review summarizes the latest advances in hydrogen evolution reaction under neutral conditions to enlighten future researches.
High purity of (7,5) SWNTs (∼79% the semisonducting SWNT ensemble) can be obtained by polymer-assisted extraction from narrow-diameter distributed produced catalyst Co-MCM-41. The fluorene-based polymers are able to selectively wrap single-walled carbon nanotubes (SWNTs) with certain chiral angles or diameters depending on their chemical structures. Poly(9,9-dioctyfluoreny1−2, 7-diyl) and poly[(9,9-dihexylfluorenyl-2,7-diyl)-co-(9,10-anthracene)] high (>24.5°). By contrast,...
The utilization of Ni(OH) 2 as a pseudocapacitive material for high performance supercapacitors is hindered by its low electrical conductivity and short cycle life. A coaxial ternary hybrid comprising amorphous deposited on multiwalled carbon nanotubes wrapped with conductive polymer (poly (3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate)) demonstrated. thin layer disordered an effective “coordinating etching precipitating” method, resulting in ultrahigh specific capacitance 3262 F g −1 at...
Abstract Synthesis of structurally controlled graphene materials is critical for realizing their practical applications. The electrochemical exfoliation graphite has emerged as a simple method to produce materials. This review examines research progress in the last 5 years, from 2015 2019. Graphene material synthesis methods generally have trade‐off between increasing production yield and achieving better property control. conditions synthesizing pristine graphene, oxide (GO), composites are...
Flexible zinc-air batteries (ZAB) are a promising battery candidate for emerging flexible electronic devices, but the catalysis-based working principle and unique semi-opened structure pose severe challenge to their overall performance at cold temperature. Herein, we report first rechargeable ZAB with excellent low-temperature adaptability, based on innovation of an efficient electrocatalyst offset electrochemical shrinkage caused by decreased temperature highly conductive hydrogel polarized...
The application of graphene‐based membranes is hindered by their poor stability under practical hydrodynamic conditions. Here, nanocarbon architectures are designed intercalating surface‐functionalized, small‐diameter, multi‐walled carbon nanotubes (MWCNTs) into reduced graphene oxide (rGO) sheets to create highly stable with improved water permeability and enhanced membrane selectivity. With the intercalation 10 nm diameter MWCNTs, reaches 52.7 L m −2 h −1 bar , which 4.8 times that...
Metal oxides of earth-abundant elements are promising electrocatalysts to overcome the sluggish oxygen evolution and reduction reaction (OER/ORR) in many electrochemical energy-conversion devices.
