Giant proton transmembrane transport through sulfophenylated graphene in a direct methanol fuel cell
Weizhe Zhang, Max Makurat, Xue Liu +21
An ideal proton exchange membrane should only permeate protons and be leak tight for fuels. Graphene is impermeable to water and poorly conducting to protons. Here, we chemically f…
Facile and Ultraclean Graphene-on-Glass Nanopores by Controlled Electrochemical Etching
Xiaoyan Zhang, Pauline M. G. van Deursen, Wangyang Fu +1
A wide range of approaches have been explored to meet the challenges of graphene nanostructure fabrication, all requiring complex and high-end nanofabrication platform and sufferin…
Ultrasensitive Field-Effect Biosensors Enabled by the Unique Electronic Properties of Graphene
Xiaoyan Zhang, Qiushi Jing, Shen Ao +4
This review provides a critical overview of current developments on nanoelectronic biochemical sensors based on graphene. Composed of a single layer of conjugated carbon atoms, gra…
Electromagnetic Absorption as a Novel Tool in Chemical Vapor Deposition Toolbox: Ultra-Fast Growth of Continuous Graphene Film
Hadi Arjmandi-Tash, Gregory F. Schneider
This report introduces the electromagnetic absorption of the catalyst as a novel knob in optimizing chemical vapor deposition of graphene. A chromium film initially deposited at on…
Topological Regard to Graphene: Elucidating the Morphology-Strain Correlation
Hadi Arjmandi-Tash, Alexander Kloosterman, Gregory F. Schneider
Graphene, dubbed as a two-dimensional material represents the topological concept of "surface" embedded in a three-dimensional space. This regard enables to employ existing theorie…
A zero-depth nanopore capillary for the analysis of translocating biomolecules
Hadi Arjmandi-Tash, Amedeo Bellunato, Chenyu Wen +4
High-fidelity analysis of translocating biomolecules through nanopores demands shortening the nanocapillary length to a minimal value. Existing nanopores and capillaries, however,…
Biaxial compression of centimeter scale graphene on strictly 2D substrate
Hadi Arjmandi-Tash, Hessam Sokooti, Jiang Lin +3
Biaxial compression of centimetre-scale graphene, freely standing on the surface of water is studied. Within this platform, we report full stress-strain compression of graphene ide…
Hybrid cold and hot-wall chamber for fast synthesis of uniform graphene
Hadi Arjmandi-Tash, Nikita Lebedev, Pauline van Deursen +2
We introduce a novel modality in the CVD growth of graphene which combines the cold-wall and hot-wall reaction chambers. This hybrid mode preserves the advantages of a cold-wall ch…
Rupture index: a quantitative measurement of sub-micrometer cracks in graphene
Hadi Arjmandi-Tash, Lin Jiang, Grégory F. Schneider
Per weight graphene is stronger than steel, but because graphene is so thin, it breaks and evidently forms cracks during handling, particularly when supporting polymers are not use…
Formation and control of wrinkles in graphene by the wedging transfer method
V. E. Calado, G. F. Schneider, A. M. M. G. Theulings +2
We study the formation of wrinkles in graphene upon wet transfer onto a target substrate, whereby draining of water appears to play an important role. We are able to control the or…
Atomic-scale electron-beam sculpting of defect-free graphene nanostructures
Bo Song, Grégory F. Schneider, Qiang Xu +3
In order to harvest the many promising properties of graphene in (electronic) applications, a technique is required to cut, shape or sculpt the material on a nanoscale without dama…
DNA Translocation through Graphene Nanopores
Grégory F. Schneider, Stefan W. Kowalczyk, Victor E. Calado +4
Nanopores -- nanosized holes that can transport ions and molecules -- are very promising devices for genomic screening, in particular DNA sequencing. Both solid-state and biologica…
Wedging Transfer of Nanostructures
Grégory F. Schneider, Victor E. Calado, Henny Zandbergen +2
We report a versatile water-based method for transferring nanostructures onto surfaces of various shapes and compositions. The transfer occurs through the intercalation of a layer…
