TL;DR: An overview of the key aspects of graphene and related materials, ranging from fundamental research challenges to a variety of applications in a large number of sectors, highlighting the steps necessary to take GRMs from a state of raw potential to a point where they might revolutionize multiple industries are provided.

TL;DR: It is shown that the two-dimensional nature of graphene oxide and its superpermeability to water combine to enable humidity sensors with unprecedented response speed (∼30 ms response and recovery times), which opens the door to various applications, such as touchless user interfaces, which is demonstrated with a 'whistling' recognition analysis.

TL;DR: This review focuses on the most recent advances in the study of pure graphene properties and novel energy solutions based on these properties and includes graphene metrology and analysis of both intellectual property and the value chain for the existing and forthcoming graphene industry.

TL;DR: In this paper, a waveguide and a spectral dispersion element are configured to be moveable attachable to a portable device, the portable device comprising a radiation sensing element and a radiation source, the apparatus being configured to provide a first configuration in which the waveguide is positioned to transmit radiation from the radiation source towards an analyte region and/or from the analyte regions towards the dispersion elements.

TL;DR: In this article, stretch-tunable metal nanoparticle mats are used for the development of optical devices, such as flexible colour filters and molecular sensors. But their performance is limited by the number of stretch-tunes required.
