High Resolution Temperature‐Resolved Spectroscopy of the Nitrogen‐Vacancy 1E Singlet State Ionization Energy

physica status solidi (a), Volume 223, Issue 6, 20 March 2026.
When light is applied to the negatively charged nitrogen‐vacancy (NV−$\mathrm{{NV}^{-}}$) in diamond, an applied magnetic field populates the 1E$\mathrm{^1E}$ singlet state. Wavelength tuned laser excitation probes the 1E$\mathrm{^1E}$ ionization threshold via changes in the NV0$\mathrm{{NV}^{0}}$ photoluminescence (PL) ratio which is the ratio between

Highly Tunable and Cell‐Remodelable Thiol‐ene Alginate‐Peptide Crosslinked Hydrogels to Recreate Cellular and Organoid Microenvironments for Biofabrication

Advanced Healthcare Materials, Volume 15, Issue 9, 6 March 2026.
Norbornene‐functionalized alginate is crosslinked with a di‐thiolated peptide sequence cleavable by cell‐secreted matrix metalloproteinases and decorated with cell‐adhesion peptides upon exposure to UV. Thyroid follicles, endometrial and intestinal organoids are encapsulated in a gentle manner with high cell viability and correct phenotype ...

Excited State Opto‐Ionic Reservoir Computing in Hybrid Perovskite Electrochemically‐Gated Luminescent Cells

Advanced Materials, Volume 38, Issue 14, 6 March 2026.
A neuromorphic computing system exploiting opto‐ionic modulation in lead halide perovskite microcrystals demonstrates high‐dimensional reservoir dynamics with diffraction‐limited node resolution. Leveraging ultrafast excited‐state interactions, it achieves efficient computation (800 pJ/node‐operation), robustly distinguishing 4‐bit pulse sequences ...
