Self‐Assembled Cobalt Oxide Nanobeads on the Conducting Van der Waals Semi‐Metal PtTe2 for Catalytic Heterostructure

Advanced Materials Interfaces, EarlyView.
Self‐assembled CoO nanobeads on the Van der Waals surface of PtTe2 were synthesized through simple thermal annealing utilizing the residual oxygen in the annealing chamber. In this study, the electrocatalytic effect for oxygen evolution reaction from CoO nanobeads on conducting PtTe2 was confirmed, elucidating the new pathway to design a ...

Reducing inhomogeneous broadening of spin and optical transitions of nitrogen-vacancy centers in high-pressure, high-temperature diamond

Communications Materials
With their optical addressability of individual spins and long coherence time, nitrogen-vacancy (NV) centers in diamond are often called “atom-like solid spin-defects”.

Self‐Assembled Fluorescent Nanodiamond Layers for Quantum Imaging

Advanced Materials Interfaces, EarlyView.
We developed a simple, scalable method for coating surfaces with fluorescent nanodiamonds. By optimizing the coating process, we created uniform, dense layers that enable high‐resolution magnetic imaging using the nitrogen‐vacancy (NV) center in nanodiamonds. This approach enables the development of cost‐effective quantum‐sensing and imaging substrates

High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.
