The electronic structures of V-intercalated TiSe and substitutionally doped dichalcogenides TiVSe have been studied using soft X-ray photoelectron, resonant photoelectron, and absorption spectroscopies. In the case of the substitution of Ti by V, the formation of coherently oriented structural fragments VSe and TiSe is observed and a small charge transfer between these fragments is found. Intercalation of the V atoms into TiSe leads to charge transfer from the V atoms to the Ti atoms with the formation of covalent complexes Ti-Se-V-Se-Ti.

Rapid advancement of flexible electronics has generated a demand for sustainable materials. Cellulose, a renewable biopolymer, exhibits exceptional mechanical strength, customizable properties, biodegradability, and biocompatibility. These attributes are largely due to its hierarchical nanostructures and modifiable surface chemistry.

The sluggish kinetics and diffusion of lithium polysulfide (LiPS) intermediates lead to the decline in the capacity and rate of high-energy lithium-sulfur (Li-S) batteries. Integrating adsorbents and electrocatalysts into the Li-S system is an effective strategy for suppressing the polysulfide shuttle and enhancing the redox kinetics of sulfur species. The disordered structure of the electrocatalysts exhibits significantly enhanced catalytic activity.

Metal-organic frameworks (MOFs) are distinguished by their structural diversity, tunable electronic properties, and exceptional performance in various applications. Notably, the electron-donating ability of ligands significantly enhances the ligand-to-metal charge transfer (LMCT) processes within these frameworks, thereby promoting efficient charge migration. Herein, we developed two electron-rich macrocyclic ligands derived from phenothiazine- and phenoxazine-functionalized calix[3]arenes, alongside their corresponding cobalt-coordinated MOFs.

Resonant three-photon ionization spectroscopy has been used to study the late 4d and 5d transition metal carbides RuC, RhC, OsC, IrC, and PtC. These species, like most diatomic transition metals with open nd subshells, exhibit an exceptionally high density of states near the ground separated atom limit. Spin-orbit and nonadiabatic interactions provide a means for the molecules to rapidly dissociate as soon as the bond dissociation energy (BDE) is exceeded.

Vagus nerve stimulation (VNS) is a promising therapy for neurological and inflammatory disorders across multiple organ systems. However, conventional rigid interfaces fail to accommodate dynamic mechanical environments, leading to mechanical mismatches, tissue irritation, and unstable long-term interfaces. Although soft neural interfaces address these limitations, maintaining mechanical durability and stable electrical performance remains challenging.
