High Voltage Mg-Doped Na 0.67 Ni 0.3 − x Mg x Mn 0.7 O 2 ( x = 0.05, 0.1) Na- Ion Cathodes with Enhanced Stability and Rate Capability
(American Chemical Society, 2016-07-26)
Magnesium substituted P2-structure Na0.67Ni0.3Mn0.7O2 materials have been prepared by a facile solid-state method and investigated as cathodes in sodium-ion batteries. The Mg-doped materials described here were characterized ...
Present and Future of Surface-Enhanced Raman Scattering
(ACS Publications, 2019-10-08)
The discovery of the enhancement of Raman scattering by molecules adsorbed on nanostructured metal surfaces is a landmark in the history of spectroscopic and analytical techniques. Significant experimental and theoretical ...
Electrolytes and Interphases in Sodium‐Based Rechargeable Batteries: Recent Advances and Perspectives
(Wiley, 2020-05)
For sodium (Na)-rechargeable batteries to compete, and go beyond the currently prevailing Li-ion technologies, mastering the chemistry and accompanying phenomena is of supreme importance. Among the crucial components of ...
On the Recovery of PLP-Molar Mass Distribution at High Laser Frequencies: A Simulation Study
(MDPI, 2019-08)
Due to the inherent difficulties in determination of the degree of branching for polymers produced in pulsed laser polymerization (PLP) experiments, the behavior of the degree of branching and backbiting reaction in high ...
Flat-shaped carbon-graphene microcomposites as electrodes for high energy supercapacitors
(Royal Society of Chemistry, 2019-06-28)
Herein, we report a simple approach for the preparation of phosphate-functionalized carbonaceous graphene-based composites. The homogeneous deposition of a thin layer of phenolic resin on the surface of graphene oxide (GO) ...
Microwave Resonant and Zero-Field Absorption Study of Doped Magnetite Prepared by a Co-Precipitation Method
(MDPI, 2014-06)
Fe3O4 and ZnxFe3-xO4 pure and doped magnetite magnetic nanoparticles (NPs) were prepared in aqueous solution (Series A) or in a water-ethyl alcohol mixture (Series B) by the co-precipitation method. Only one ferromagnetic ...
Photorelease of Pyridyl Esters in Organometallic Ru(II) Arene Complexes
