Summary: Ensembles of nitrogen-vacancy centers are used to detect nuclear magnetic resonance signals from micron-sized samples. The large magnetic field regime is of particular interest due to the high thermal polarization and accessibility of chemical shifts and J couplings. However, coupling NV-based sensors with high-frequency nuclear signals has been challenging. This Letter presents a method that overcomes this obstacle and achieves high spectral resolutions, limited only by the coherence of the nuclear spin signal.

Summary: In this work, a novel atomically thin, all van der Waals SQUID is constructed, in which current flows between NbSe2 contacts through parallel graphene weak links. The 2D planar SQUID remains stable at high in-plane fields, enabling the tracing of critical current interference patterns and the observation of a field-driven transition. The asymmetric SQUID geometry is further suggested for directly probing current density in the absence of phase information.

Summary: In a voltage-varying experiment of Hall thrusters, inward deflection of the excitation magnetic field was observed. The influence of Hall current magnitude and radial distribution on the total magnetic field was analyzed using magnetic field simulations. The probable reason for the inward deflection at high discharge voltages (>600 V) was obtained by combining simulation results and theoretical analysis. This study provides qualitative guidance for the design of excitation magnetic field in high-specific-impulse Hall thrusters.

Summary: This study demonstrates that photothermia at the nanoscale can trigger the degradation of magnetic nanoparticles, leading to the release of Fe(II) and enabling photothermo-ferroptotic therapy. The temperature acts as an accelerator for nanoparticle degradation and can be remotely triggered by laser-mediated photothermal conversion. The efficacy of this treatment method has been confirmed in in vitro experiments.

Summary: A facile polymer-directed metal-organic framework (MOF)-based nanoarchitechtonics was developed to enhance the catalytic efficiency of multi-enzyme cascade reactions through substrate channeling. The new method involved the simultaneous synthesis of MOF and co-immobilization of enzymes, resulting in a closely packed nanoarchitecture with enhanced substrate channeling. The enzyme cascade reaction system showed a 3.5-fold increase in catalytic activity compared to free enzymes.

Summary: An electrochemical biosensor based on rolling circle amplification (RCA) was developed for the detection of lead ion (Pb2+). The biosensor utilized Pb2+-dependent DNAzyme and DNA-templated silver nanoclusters (DNA-AgNCs) for amplification, and showed high sensitivity and selectivity for Pb2+ analysis in the range of 1 pM-10 μM with a detection limit of 0.3 pM. This strategy has potential applications in real water samples and environment analysis.

Summary: This study demonstrates that NbB2 nanoflakes exhibit excellent selectivity and durability in ambient electrochemical N-2 reduction reaction, leading to efficient NH3 production. The high selectivity is attributed to the presence of abundant active vacancies on the surface, which makes the N-N triple bonds in N-2 molecule easier to break for NH3 production.
