A Compact Incubation Platform for Long‐Term Cultivation of Biological Samples for Nitrogen‐Vacancy Center Widefield Microscopy

Advanced Materials Technologies, EarlyView.
A compact incubation platform enables long‐term cultivation of biological samples directly on diamond quantum sensors for NV widefield magnetometry. The 3D‐printed biocompatible chamber provides a temperature controlled, CO2${\rm CO}_2$ and humidity rich environment while accommodating total internal reflection excitation geometry.

Quantum Electrometry of Non‐Volatile Space Charges in Diamond

Advanced Optical Materials, EarlyView.
Charges are generated when nitrogen vacancy qubits in diamond are illuminated by light. Transport and trapping in an electric field leads to the formation of large, stable space charge patterns that dynamically screen applied electric fields, impacting electric field sensing and photoelectric detection.

Decoherence in rf SQUID Qubits

, 2008
We report measurements of coherence times of an rf SQUID qubit using pulsed microwaves and rapid flux pulses. The modified rf SQUID, described by an double-well potential, has independent, in situ, controls for the tilt and barrier height of the ...

Quantum Decoherence of Nitrogen‐Vacancy Spin Ensembles in a Nitrogen Spin Bath in Diamond Under Dynamical Decoupling

Advanced Optical Materials, EarlyView.
Combining high‐order cluster‐correlation expansion with experiment, it is revealed that P1‐driven NV decoherence under dynamical decoupling deviates from semi‐classical scaling laws. The coherence‐time exponent depends on pulse number and bath conditions, demonstrating the necessity of a full quantum bath description.

Grounding Large Language Models for Robot Task Planning Using Closed‐Loop State Feedback

Advanced Robotics Research, EarlyView.
BrainBody‐Large Language Model (LLM) introduces a hierarchical, feedback‐driven planning framework where two LLMs coordinate high‐level reasoning and low‐level control for robotic tasks. By grounding decisions in real‐time state feedback, it reduces hallucinations and improves task reliability.

Evaluating Bicarbonate Electrolyzer Configurations for Energy‐Efficient Formate Production

Advanced Sustainable Systems, EarlyView.
Reactive carbon capture (RCC) with bicarbonate electrolyzers (BEs) offers an efficient alternative to gas‐fed CO2 electrolyzers by eliminating regeneration and pressurization steps. This study optimizes BE configurations and compares RCC chains to gas‐fed carbon chains for formate production.

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

Advanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...
