‘Oxygen Bound to Magnesium’ as High Voltage Redox Center Causes Sloping of the Potential Profile in Mg‐Doped Layered Oxides for Na‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Na‐ion batteries ‐ Impact of doping on the oxygen redox: The sloping potential of NaMg0.1Ni0.4Mn0.5O2 above 4.0 V is caused by a new redox center (arising from the ‘O bound to Mg’), having a higher potential but being more irreversible compared to the ‘O bound to Ni’.

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation

open access: yesAdvanced Functional Materials, EarlyView.
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.

Geometrically‐Screened, Sterically‐Hindered Additive for Wide‐Temperature Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A molecular‑engineering strategy combining steric hindrance tuning with geometric optimization identifies cellobiose as an ideal additive for aqueous zinc‑ion batteries, enabling stable Zn deposition across a wide temperature range from −30 to 50 °C. Abstract Aqueous zinc‐ion batteries (AZIBs) are emerging as a highly promising alternative to lithium ...

從電子出版與電子商務看學術出版的發展 E-publishing and E-commerce on Scholarly Publishing [PDF]

open access: yesJiàoyù zīliào yǔ túshūguǎn xué, 2003
學術出版不但促進了學術傳播,也增進了人類的文明。走過這幾百年,學術出版雖歷經各種變革,然而仍以紙本印刷方式出版為主。近年來由於資訊科技、數位化的快速演進及高速、無遠弗屆的網際網路出現,促使學術出版產生了巨變。本文即從電子出版及電子商務的角度來探討學術出版,同時指出以加值出版為理念,並在價值鏈上進行各種核心加值與服務作業,以為學術出版未來之發展方向。Scholarly publishing is not only to promote scholarly communication but also to
