Abstract:
... It is very important to prevent bacterial colonization at the early postoperative stages. There are four major strategies and their corresponding types of antibacterial surfaces specifically designed to fight infection: bactericide release, anti-adhesion, pH-sensitive, and contact-killing. Herein, we aimed at determining the antibacterial efficiency of different types of bactericidal ions and reve ...

Abstract:
... The low electrical conductivity and ordinary lithium-ion transfer capability of Li₄Ti₅O₁₂ restrict its application to some degree. In this work, dual-phase Li₄Ti₅O₁₂–TiO₂ (LTOT) was modified by composite zirconates of Li₂ZrO₃, Li₆Zr₂O₇ (LZO) to boost the rate capabilities and cyclability. When the homogeneous mixture of LiNO₃, Zr(NO₃)₄·5H₂O and LTOT was roasted at 700 °C for 5 h, the obtained comp ...

Subject:
X-ray photoelectron spectroscopy; anodes; batteries; cathodes; corrosion; electrochemistry; electrolytes; lithium; materials science; scanning electron microscopy; sulfur
Abstract:
... Lithium–sulfur (Li–S) batteries suffer from shuttle reactions during electrochemical cycling, which cause the loss of active material sulfur from sulfur–carbon cathodes, and simultaneously incur the corrosion and degradation of the lithium metal anode by forming passivation layers on its surface. These unwanted reactions therefore lead to the fast failure of batteries. The preservation of the high ...

Abstract:
... Light-emitting electrochemical cells (LEECs) from ionic transition-metal complexes (iTMCs) offer the potential for high-efficiency electroluminescence in a simple, single-layer device. However, LEECs typically rely on the use of rare metal complexes. This has limited their cost effectiveness and put constraints on their applicability. With a view to leveraging the efficient emission of these compl ...

Abstract:
... Two-dimensional (2D) particles, including transition metal carbides (MXenes), often exhibit large lateral-size polydispersity in delaminated colloidal solutions. This heterogeneity results in challenges when conducting fundamental studies, such as investigating correlations between properties and the 2D flake size. To resolve this challenge, we have developed solution-processable techniques to con ...
