What is LiFi

Harald Haas, +3 more
- 15 Mar 2016 - 
TL;DR: This paper will show how LiFi takes VLC further by using light emitting diodes (LEDs) to realise fully networked wireless systems to illustrate that LiFi attocells are not a theoretical concept any more, but at the point of real-world deployment.
Journal ArticleDOI

Facile preparation and upconversion luminescence of graphene quantum dots

Jianhua Shen, +4 more
- 14 Feb 2011 - 
TL;DR: A facile hydrazine hydrate reduction of graphene oxide with surface-passivated by a polyethylene glycol (PEG) method for the fabrication of graphene quantum dots (GQDs) with frequency upconverted emission with speculation on the upconversion luminescence due to the anti-Stokes photoluminescence.
Proceedings ArticleDOI

What is LiFi

Harald Haas, +1 more
TL;DR: Light-Fidelity takes visible light communication (VLC) further by using light emitting diodes (LEDs) to realise fully networked wireless systems for the Internet-of-Things (IoT), 5G and beyond.
Journal ArticleDOI

In-situ pyrolysis of Enteromorpha as carbocatalyst for catalytic removal of organic contaminants: Considering the intrinsic N/Fe in Enteromorpha and non-radical reaction

Cheng Chen, +10 more
- 05 Aug 2019 - 
TL;DR: An environmentally friendly, facile, and economical Fe/N co-doped carbonaceous material (Fe-N@C) was prepared by the in-situ pyrolysis of Fe rich Enteromorpha biomass for peroxymonosulfate activation and organic contaminants degradation.
Journal ArticleDOI

Interphase Engineering Enabled All-Ceramic Lithium Battery

Fudong Han, +9 more
- 21 Mar 2018 - 
TL;DR: Li et al. as mentioned in this paper proposed an all-ceramic cathode/electrolyte with an extremely low interfacial resistance, which can be realized by thermally soldering LiCoO 2 (LCO) and LLZO together with the Li 2.3−x C 0.7+x B 0.3 O 3 solder.
