TL;DR: In this paper, the surface modified LiMn1.42Ni0.42Co0.16O4 with cation disorder in the 16d octahedral sites has been surface modified with 2 wt % nanosize Al2O3, ZnO, Bi2O 3, and AlPO4 by an electrostatic self-assembly method.
Abstract: The 5 V spinel cathode LiMn1.42Ni0.42Co0.16O4 with cation disorder in the 16d octahedral sites has been surface modified with 2 wt % nanosize Al2O3, ZnO, Bi2O3, and AlPO4 by an electrostatic self-assembly method. The bare and surface-modified samples have been characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), high-resolution transmission electron microscopy (TEM), charge−discharge measurements in lithium cells, electrochemical impedance spectroscopy (EIS), and X-ray photoelectron spectroscopy (XPS). The surface-modified samples exhibit better cycling performance, better rate capability, and better rate capability retention during cycling compared to the bare sample. EIS and XPS studies show that the inferior electrochemical performances of the bare LiMn1.42Ni0.42Co0.16O4 are closely related to the formation of thick solid-electrolyte interfacial (SEI) layer at the high operating voltages of ∼5 V. Surface modifications with nanosize Al2O3, ZnO, Bi2O3, and AlPO4 supp...

TL;DR: In this paper, a modified microfibrillated cellulose (MFC) was prepared by disintegration of bleached softwood sulphite pulp through mechanical homogenization, and the surface of the MFC was modified using different chemical treatments, using reactions both in aqueous and organic solvents.
Abstract: Microfibrillated cellulose (MFC) was prepared by disintegration of bleached softwood sulphite pulp through mechanical homogenization. The surface of the MFC was modified using different chemical treatments, using reactions both in aqueous- and organic solvents. The modified MFC was characterized with fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). Epoxy functionality was introduced onto the MFC surface by oxidation with cerium (IV) followed by grafting of glycidyl methacrylate. The length of the polymer chains could be varied by regulating the amount of glycidyl methacrylate added. Positive charge was introduced to the MFC surface through grafting of hexamethylene diisocyanate, followed by reaction with the amines. Succinic and maleic acid groups could be introduced directly onto the MFC surface as a monolayer by a reaction between the corresponding anhydrides and the surface hydroxyl groups of the MFC.
