Application on gold nanoparticles-dotted 4-nitrophenylazo graphene in a label-free impedimetric deoxynivalenol immunosensor
(MDPI, 2015)In this paper, we report a new concept to construct a label-free electrochemical inhibition-based immunosensor for the detection of the mycotoxin deoxynivalenol (DON) in cereal samples. The electrochemical impedance ... -
Complexation-based detection of nickel(ii) at a graphene-chelate probe in the presence of cobalt and zinc by adsorptive stripping voltammetry
(MDPI, 2017)The adsorptive stripping voltammetric detection of nickel and cobalt in water samples at metal film electrodes has been extensively studied. In this work, a novel, environmentally friendly, metal-free electrochemical ... -
Few-layer binder free graphene modified mercury film electrode for trace metal analysis by square wave anodic stripping voltammetry
(ESG, 2013)A binding agent free graphene modified glassy carbon electrode in combination with an in situ plated mercury film electrode (Gr-GC-HgFE) was used as a highly sensitive electrochemical platform for the determination of Zn2+, ... -
High power asymmetric supercapacitor based on activated carbon/reduced graphene oxide electrode system
(Elsevier, 2023-02-22)We synthesized Graphene oxide (GO) using the modified Hummers method and further reduced to reduced graphene oxide (rGO) using hydrazine monohydrate and ammonia solution. The prepared materials were interrogated using ... -
Hydrogen storage behavior of magnesium catalyzed by nickel-graphene nanocomposites
(ScienceDirect, 2019)In present study nanocomposites of Graphene Like Material (GLM) and nickel containing 5–60 wt % Ni were prepared by a co-reduction of graphite oxide and Ni2+ ions. These nanocomposites served as effective catalysts of ... -
Metal hydride – Graphene composites for hydrogen based energy storage
(Elsevier, 2021)The paper presents a review of the authors’ studies of advanced functional composites of graphene based materials with metals, alloys, intermetallic compounds and their hydrides, and on the creation on their basis of ...
