The structural stability of graphene anticorrosion coating materials is compromised at low potentials
(2015)
Corrosion of engineered structures is a major problem causing an estimated economic loss of more than 2 trillion US dollars annually worldwide. Graphene has recently emerged as highly promising, low-cost, and transparent ...
Transition metal (Mn, Fe, Co, Ni)-doped graphene hybrids for electrocatalysis
(2013)
The development of electrocatalysts is crucial for renewable energy applications. Metal-doped graphene hybrid materials have been explored for this purpose, however, with much focus on noble metals, which are limited by ...
Etched nanoholes in graphitic surfaces for enhanced electrochemistry of basal plane
(2017)
The understanding and tailoring of the electrochemistry of graphite is of significant industrial importance. We develop a method of etching pits into the basal planes of highly oriented pyrolytic graphite (HOPG) by ...
Direct voltammetric determination of redox-active iron in carbon nanotubes
(2014)
With the advances in nanotechnology over the past decade, consumer products are increasingly being incorporated with carbon nanotubes (CNTs). As the harmful effects of CNTs are suggested to be primarily due to the bioavailable ...
Cytotoxicity of exfoliated transition-metal dichalcogenides (MoS2, WS2, and WSe2) is lower than that of graphene and its analogues
(2014)
Studies involving transition-metal dichalcogenides (TMDs) have been around for many decades and in recent years, many were focused on using TMDs to synthesize inorganic analogues of carbon nanotubes, fullerene, as well as ...
Graphene oxides : transformations in natural waters over a period of three months
(2014)
Graphene oxide (GO), a derivative of graphene consisting of various oxygen moieties, has gained popularity owing to its excellent physiochemical properties and applicability in various fields. GO nanomaterials can be ...
Chemical energy powered nano/micro/macromotors and the environment
(2015)
The rise of miniaturized artificial self-powered devices, demonstrating autonomous motion, has brought in new considerations from the environmental perspective. This review addresses the interplay between these ...
Graphene oxides prepared by Hummers’, Hofmann’s, and Staudenmaier’s methods : dramatic influences on heavy-metal-ion adsorption
(2014)
Graphene oxide (GO), an up-and-coming material rich in oxygenated groups, shows much promise in pollution management. GO is synthesised using several synthetic routes, and the adsorption behaviour of GO is investigated to ...
Mycotoxins : simultaneous detection of zearalenone and citrinin by voltammetry on edge plane pyrolytic graphite electrode
(2014)
Mycotoxins are highly toxic compounds often found in the food. It is of paramount importance to have analytical technique for point-of-care on-spot detection for authorised personnel to immediately take the action required. ...
Nanoporous carbon materials for electrochemical sensing
(2012)
Nanoporous carbon materials are highly important materials for a wide array of applications. Here we show that nanoporous carbon can act as highly active materials for electrochemical sensing. We observed that nanoporous ...
