Graphene oxide fibers by microfluidics assembly: a strategy for structural and dimensional control

Abstract

Graphene oxide (GO) microfibers with controlled and homogeneous shape and tunable diameter were fabricated using the 3 dimensional (3D) hydrodynamic focusing concept on a microfluidic device. Thermal and microwave treatments...

Laser Reduced Graphene Oxide Electrode for Pathogenic Escherichia coli Detection

“…The 2D band, at ∼2700 cm –1 , was only present in the LRGO samples. Previous publications ,, have assigned the D peak to the primary in plane vibrations of graphene, so it can be used to estimate the degree of defects and disorder within the hexagonal lattice. The 2D peak is attributed to second-order in-plane vibrations of graphene.…”

Integrated membranes within centrifugal microfluidic devices: a review

“…Restoration of electrical conductivity can be achieved through thermal, chemical, dielectric, or photo-reduction, resulting in what is known as reduced GO (rGO). 116,117 However, although the electrical conductivity of rGO is considered sufficient for many applications, it does not achieve the same level of efficiency as pristine graphene. 112 Though not commercially available, the straightforward synthesis of GO membranes from inexpensive graphite powders has been described extensively within the literature, 118–121 with a vast array of different techniques available for tuning interlayer spacing and membrane stability.…”

The First Edition of the World Nanotechnology Marathon [Spotlight Column]

“…The possibility of enabling spintronics with heavy metals, topological insulators and antiferromagnets was addressed [17], along with a perspective on the modeling and design of spintronics oscillator-based applications [18], and the state of the art and future of spintronic for microwave and Thz detectors [19]. The value and potential for nanobiomedicine was demonstrated with talks about a miniaturized, high throughput platform for cancer biology research [20], and the status of MeMs and Dna nanotechnology and its challenges [21], and graphene-based technologies for biosensors, from field-effect transistors to microfiber-based devices [22]. atomic layer neutral beam processes for nanofabrication and interface engineering [23], tetrapods-based 3-D nanomaterials for advanced technologies [24], and reactive printing, compatible with r2r processes, for the self-assembly of nanoparticles and quantum dots for photonics and CoViD-19 applications [25] were introduced as innovative nanofabrication approaches.…”
