All‐Optical Electric Field Sensing with Nanodiamond‐Doped Polymer Thin Films
The photoluminescence (PL) of fluorescent nanodiamonds (FNDs) in a polymer‐based capacitor device is sensitive to electric fields. When an external electric field is applied, the PL intensity of the negatively charged nitrogen‐vacancy center (NV‐) increases, while that of the neutrally charged NV center (NV0) decreases.

Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions
Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...

This work presents a novel sensing platform using metallo‐dielectric cryosoret nano‐assemblies and lossless photonic crystals to overcome limitations of conventional plasmonic biosensors. The hybrid system enhances both electric and magnetic field interactions, enabling amplified fluorescence, ultralow detection limits, and prism‐free, objective‐free ...

Narrow Inhomogeneous Distribution and Charge State Stabilization of Lead‐Vacancy Centers in Diamond
Lead‐vacancy (PbV) centers in diamond are expected to be a building block of quantum network nodes owing to a large ground state splitting, which suppresses phonon interaction. In this study, multiple PbV centers with nearly identical photon frequencies and stable charge state are fabricated by high‐pressure and high‐temperature anneal up to 2300 °C ...

A miniaturized, label‐free, and enzyme‐free biosensor (miR‐TFT) enables direct electrical detection of microRNA (miRNA) with single‐nucleotide specificity and a detection limit of 0.6 fM. Built on a tri‐channel In2O3/ZnO heterojunction and functionalized with bespoke peptide nucleic acid (PNA) probes, the device is robust, reusable, and compatible with

This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...
