Silicon-carbon (Si@C) composite anodes are promising candidates for next-generation lithium-ion batteries (LIBs) due to their high theoretical capacity and potential for increased energy density. However, their practical application is limited by large volume changes during lithiation/delithiation, which leads to particle cracking and electrochemical fading. Herein, we report the deposition of hybrid organic/inorganic zincone coatings on Si@C composite anodes by molecular layer deposition (MLD). Using diethylzinc (DEZ) in combination with ethylene glycol (EG) or ethanolamine (EA), conformal nanoscale thin film coatings were produced to act as artificial solid electrolyte interphase (ASEI) layers. Structural and chemical characterization using advanced characterization confirmed a successful growth of ultrathin hybrid zincone thin films while preserving the bulk structure of the Si@C particles. After 100 cycles, ZnEA and ZnEG -coated Si@C electrodes maintained improved capacitances compared to the uncoated electrode, demonstrating improved electrochemical performance of ~20% and ~30%, respectively. Post-cycling analyses further demonstrated reduced structural degradation and cracking formation on the surface of the zincone coated electrodes. The enhanced performance is attributed to the synergistic effect of the hybrid zincone coating, where the inorganic zinc precursor component suppresses electrolyte decomposition and stabilizes the electrode/electrolyte interface, while the organic precursor provides mechanical flexibility to accommodate silicon volume expansion. These findings demonstrate that zincone coatings is an effective method for stabilizing high-capacity silicon-based anodes for advanced next-generation LIBs with improved long-term cycling performance.

Light-tissue interaction is common in clinical treatments and medical researches, therefore the investigation of light path in irradiated tissue is of high importance. The innovation of this application rises from the combination of two different research areas: theoretical models of light path in irradiated tissues (Diffusion Reflection- DR) and the optical properties of gold nanoparticles. These theoretical models, which were developed about twenty years ago, suggested different reflection profiles for different tissue structures. Still, a diagnostic tool for cancer detection, based on these theoretical models, was still not developed. The use of gold nanoparticles as absorption contrast agents introduces the DR measurements of tumors as a highly sensitive, simple method for cancer detection purposes
