Metal-Free Dihydrogen Oxidation by a Borenium Cation:A Combined Electrochemical/Frustrated Lewis Pair Approach [PDF]

open access: yes, 2014
In order to use H2 as a clean source of electricity, prohibitively rare and expensive precious metal electrocatalysts, such as Pt, are often used to overcome the large oxidative voltage required to convert H2 into 2 H+ and 2 e−. Herein, we report a metal-

Selenium Nanomaterials for Wound Healing: Synergistic Strategies from Anti‐Infection to Tissue Regeneration

open access: yesAdvanced NanoBiomed Research, EarlyView.
Selenium nanoparticles (SeNPs) are emerging as multifunctional platforms for wound healing, integrating antimicrobial, anti‐inflammatory, and proregenerative activities. This review summarises key mechanisms and recent advances in SeNP‐enabled composite dressings, immunomodulatory nanocomposites, microenvironment‐responsive hydrogels, photothermal and ...

KNH2 - KH: a metal amide - hydride solid solution [PDF]

open access: yes, 2016
We report for the first time the formation of a metal amide-hydride solid solution. The dissolution of KH into KNH2 leads to an anionic substitution, which decreases the interaction among NH2 - ions.

LiSc(BH_4)_4 as a Hydrogen Storage Material: Multinuclear High-Resolution Solid-State NMR and First-Principles Density Functional Theory Studies [PDF]

open access: yes, 2009
A lithium salt of anionic scandium tetraborohydride complex, LiSc(BH_4)_4, was studied both experimentally and theoretically as a potential hydrogen storage medium. Ball milling mixtures of LiBH_4 and ScCl_3 produced LiCl and a unique crystalline hydride,

The effects of halogen elements on the opening of an icosahedral B12 framework [PDF]

open access: yes, 2017
The fully halogenated or hydrogenated B12X12 (X = H, F, Cl, Br and I) clusters are confirmed to be icosahedral. On the other hand, the bare B12 cluster is shown to have a planar structure. A previous study showed that a transformation from an icosahedron
