Improvement of Cycling Performance of Na2/3Co2/3Mn1/3O2 Cathode by PEDOT/PSS Surface Coating for Na Ion Batteries

open access: yesIndonesian Journal of Chemistry, 2018
The surface-modified Na2/3Co2/3Mn1/3O2 is coated with a conductive Poly (3,4-Ethylene dioxy thiophene)-poly (styrene sulfonate) (PEDOT/PSS) polymer, and their resulting electrochemical properties were investigated as Na-ion battery cathode.

Surface modification of poly(vinylidene fluoride) hollow fibre membranes for biogas purification in a gas–liquid membrane contactor system [PDF]

open access: yesRoyal Society Open Science, 2017
The wetting of hollow fibre membranes decreases the performance of the liquid–gas membrane contactor for CO2 capture in biogas upgrading. To solve this problem, in this work, a poly(vinylidene fluoride) (PVDF) hollow fibre membrane for a liquid–gas ...

Cross-Linked and Surface-Modified Cellulose Acetate as a Cover Layer for Paper-Based Electrochromic Devices [PDF]

open access: yesACS Applied Polymer Materials, 2021
We studied the surface and microstructure of cellulose acetate (CA) films to tailor their barrier and mechanical properties for application in electrochromic devices (ECDs). Cross-linking of CA was carried out with pyromellitic dianhydride to enhance the properties relative to unmodified CA: solvent resistance (by 43% in acetone and 37% in DMSO ...

Simple synthesis of layered H-octosilicate in situ surface-modified with lecithin

open access: yesApplied Clay Science, 2020
Abstract A simple process to synthesize H-octosilicate that is coated with a biocompatible natural surfactant lecithin has been developed, where the hydrothermal synthesis of Na-octosilicate, ion exchange of sodium ions in Na-octosilicate with protons, and surface modification with hydrogenated soy lecithin are sequentially performed in an identical ...

Influence of magnetic property for workpiece on thickness of removal and modified layers in large-area EB irradiation

open access: yesNihon Kikai Gakkai ronbunshu, 2019
In a large-area electron beam (EB) irradiation method developed recently, the large-area EB with high energy density can be obtained without focusing the beam. It can be used for melting and evaporating metal surface instantly.
