TL;DR: The obtained phosphorus-doped graphene quantum dots exhibit excellent scavenging activity of free radicals, such as hydroxyl radicals (˙OH) and 2,2-diphenyl-1-picrylhydrazyl (DPPH).
Abstract: In this work, phosphorus-doped graphene quantum dots (P-GQDs) with a high phosphorus doping content (>7 at%) are synthesized via an electrochemical approach. Sodium phytate (C6H6Na12O24P6), a green food antioxidant additive, is used as the electrolyte for providing both a phosphorus source and an electrolysis environment. The obtained P-GQDs exhibit excellent scavenging activity of free radicals, such as hydroxyl radicals (˙OH) and 2,2-diphenyl-1-picrylhydrazyl (DPPH). Combined with Raman, FT-IR, and XPS spectral analyses, the reason for high phosphorus content and the mechanism of free radical scavenging of P-GQDs are investigated in our work.

TL;DR: In this paper, a new model for predicting the reacted fraction of hydriding/dehydriding in powder hydrogen storage materials has been developed, which offers an analytic form expressing the reaction fraction of hydrogen absorption/desorption (A/D) as a function of time, temperature and pressure explicitly.

TL;DR: A heterogeneous multi-layer 5G cellular architecture with a control plane and user plane separation scheme is presented and several key technologies employed in VLC downlink communications, including modulation, multiple access, and error control schemes are discussed.
Abstract: Visible light communication has gained tremendous attention recently and has become a favorable complementary technology to millimeter- wave communication in short-range communication scenarios for future 5G networks. VLC possesses a number of prominent features to address the highly demanding 5G system requirements for high capacity, high data rate, high spectral efficiency, high energy efficiency, low battery consumption, and low latency. These prominent features include but are not limited to abundant license-free spectrum, the ability to provide multiple gigabit-per-second data rates, low energy consumption, and low implementation costs. In this article a heterogeneous multi-layer 5G cellular architecture with a control plane and user plane separation scheme is presented. Three layers — the macrocell layer operating below 3 GHz, the picocell layer operating in the mmWave spectrum, and the optical attocell layer operating at the visible spectrum — are considered in this architecture, with each layer targeting a different coverage and communication need. We further address potential solutions for uplink communications, backhaul connections, and downlink communications in an optical attocell. Several key technologies employed in VLC downlink communications, including modulation, multiple access, and error control schemes, are also discussed.

TL;DR: In this paper, the effect of the functional groups on the electrochemical properties of supercapacitors was investigated by treating porous carbon with pore size of 80nm (C80) with concentrated nitric acid and found that the increase of nitrogen and oxygen groups in the surface results in the improvement of wettability.

TL;DR: In this article, a numerical approach using the bonded-particle model (BPM) is adopted to investigate the acoustic emission characteristic of rock under different compressive loading rates, and it reveals that under uniaxial compressive test, the physical mechanism and distribution of AE events recorded by the BPM are generally consistent with the phenomena observed from the laboratory experiments.
