TL;DR: Recent advantages in graphene preparation, sensor construction, and sensing properties of various graphene-based gas/vapor sensors, such as NH3, NO2, H2, CO, SO2,H2S, as well as vapor of volatile organic compounds are summarized.

TL;DR: A green, large-scale and high-output heterogeneous synthesis of N-doped CDs was developed by reacting calcium citrate and urea under microwave irradiation without the use of any capping agents to exhibit good aqueous solubility and yellowish-green fluorescence in the solid and aqueously states.

TL;DR: The development of CDs as nanoprobes is still in its infancy, but continued progress may lead to their integration into environmental and biological applications as discussed by the authors, where the authors reviewed the applications of fluorescent carbon dots in salt ions, organic/biological molecules and target gases.

TL;DR: Graphene, as an intermediate phase between fullerene and carbon nanotube, has aroused much interest among the scientific community due to its outstanding electronic, mechanical, and thermal properties.

TL;DR: The NiO p-type semiconducting nanowires with high aspect ratios up to approximately 2000 have been prepared by chemical reduction under assistance of magnetic fields and subsequent heat treatment method as discussed by the authors.
