Development of polymer composites using modified, high-structural integrity graphene platelets

TL;DR: In this article, a covalently modified 3-nm thick graphene platelets (GnPs) by the reaction between the GnPs' epoxide groups and the end-amine groups of a commercial long-chain surfactant (M w ǫ = 2000), compounded the modified platelets with a model polymer epoxy, and investigated the structure and properties of both m -GNPs and their epoxy composites.
Journal ArticleDOI

High-voltage Zn/LiMn0.8Fe0.2PO4 aqueous rechargeable battery by virtue of “water-in-salt” electrolyte

TL;DR: In this paper, a LiMn 0.8 Fe 0.2 PO 4 cathode and a Zn anode are combined in a full cell possessing a high operating voltage exceeding 1.8 V. The high reversibility of the system enables sustaining more than 150 cycles without obvious capacity fading.
Journal ArticleDOI

How does magnetic resonance imaging influence staging according to AJCC staging system for nasopharyngeal carcinoma compared with computed tomography

TL;DR: The use ofMRI caused dramatic changes in the results of the T stage and clinical staging and should be preferred to CT in staging NPC and patients would benefit from changes in treatment strategies resulting from the use of MRI.

Selecting Substituent Elements for Li-Rich Mn-Based Cathode Materials by Density Functional Theory (DFT) Calculations

TL;DR: In this paper, density function theory (DFT) calculations were performed to select dopants from a series of transition metals including Ti, V, Cr, Fe, Co, Ni, Zr and Nb. Based on the calculations, Nb is chosen as an dopant, because Nb substitution is predicted to increase the electronic conductivity, donate extra electrons for charge compensation and postpone the oxygen release reaction during delithiation.
