Non-equilibrium plasmachemical deposition using platinum(II) hexafluoroacetylacetonate precursor leads to the single-step formation of nanocomposite layers comprising an organic host matrix embedded with metal particles of size less than 5 nm. These multifunctional nanocomposite films are found to display both ionic and electronic conductivities.

Free-standing nanowires can gain intracellular access without causing stress or apoptosis. Current approaches to generate nanowires focus on lithographic patterning and inorganic materials (Si, GaAs, AlO, etc.) while organic materials are less explored.

Exploiting high-performance gas sensors is desirable for the on-site and accurate detection of drug precursor chemical gases. Here, the electron-proton conductivity metal-organic frameworks M(HIB) were designed to discriminate typical drug precursor chemical gases. The strong d-π conjugation and substantial HO ligands in M(HIB) generate conducting pathways for electrons and protons, which contribute to novel gas-sensing properties.

Lithium (Li) metal is considered to be one of the most promising anodes for next-generation high-energy-density batteries owing to its high theoretical capacity and low redox potential. However, the practical application of Li metal anodes has been hindered by the unstable interface and the growth of Li dendrites. Herein, a highly stable surface-patterned Li metal anode has been developed, in which composite nanowires composed of lithium phosphide and copper nanoparticles are riveted within the regular grooves of the Li metal surface.

To enable the practical application of lithium metal batteries, it is crucial to address the challenges of dendrite growth and volume expansion in lithium metal anodes. A 3D framework offers an effective solution to regulate the lithium plating/stripping process. In this work, we present a 3D mixed ion-electron conducting (MIEC) framework as a lithium metal anode, achieved by conformally coating carbon nanotubes (CNTs) onto LiLaTiO (LLTO) particles.

In situ carbon dioxide (CO) outgassing is a common phenomenon in lithium-ion batteries (LiBs), primarily due to parasitic side reactions at the cathode-electrolyte interface. However, little is known about the chemical origins of the in situ CO released from emerging Li-excess cation-disordered rock salt (DRX) cathodes. In this study, we selectively labeled various carbon sources with C in cathodes containing a representative DRX material, LiMnTiO (LMTO), and performed differential electrochemical mass spectrometry (DEMS) during galvanostatic cycling in a carbonate-based electrolyte.
