A review of top-down and bottom-up synthesis methods for the production of graphene, graphene oxide and reduced graphene oxide

TL;DR: Graphene is a two-dimensional material with extraordinary optical, thermal, mechanical, and electrical properties as mentioned in this paper , which has a versatile surface chemistry and large surface area, and has been used extensively in environmental applications.

TL;DR: Graphene-based sensors for health monitoring have been extensively studied in recent years as the demand for real-time human healthcare applications and seamless human-machine interaction has risen exponentially as mentioned in this paper .

TL;DR: In this paper , the authors highlight the functional annotation of the combined impact of nanomaterials and plant probiotics on sustainable agricultural production in an eco-friendly manner, and highlight that the combination of NMs and PPs can also assist in the controlled and targeted delivery of entrapped components and also increase the shelf life of PPs.

TL;DR: In this article , a comprehensive review of the development of two-dimensional layered materials (2DLMs) and their nanocomposites in electrochemical sensors and biosensors is presented, where 2DLMs include graphene and its derivatives, MXenes, phosphorene, transition metal dichalcogenides, and metal-organic frameworks.

TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.

Abstract: The preparation of graphitic oxide by methods described in the literature is time consuming and hazardous. A rapid, relatively safe method has been developed for preparing graphitic oxide from graphite in what is essentially an anhydrous mixture of sulfuric acid, sodium nitrate and potassium permanganate.

TL;DR: In this paper, a colloidal suspension of exfoliated graphene oxide sheets in water with hydrazine hydrate results in their aggregation and subsequent formation of a high surface area carbon material which consists of thin graphene-based sheets.

TL;DR: It is shown that graphene grows in a self-limiting way on copper films as large-area sheets (one square centimeter) from methane through a chemical vapor deposition process, and graphene film transfer processes to arbitrary substrates showed electron mobilities as high as 4050 square centimeters per volt per second at room temperature.
