Imidazolium‐mediated crosslinking transforms 6FDA‐durene PI from tribo‐negative to tribo‐positive by modulating the surface electronic structure and charge‐transfer behavior. DFT calculations confirm the experimentally observed polarity transition.

A novel dispersion‐phase defect‐healing strategy using Br‐doped PbS quantum dots (QDs) significantly stabilizes CsPbI3 perovskite (Pe) QDs by passivating internal vacancies. This approach reduces trap‐assisted nonradiative recombination, enabling high‐performance indoor photovoltaics with exceptional stability.

Scalable Room‐Temperature Terahertz Graphene Cameras
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

This paper presents the first results from the DynamiX X‐ray imaging detector developed by the UK's Science and Technology Facilities Council for a new generation of photon light sources. Operating at a continuous frame rate of 534 kHz and with a per‐pixel per‐frame dynamic range of roughly five orders of magnitude, this work is the first step in ...

Summary Boosting slow‐wave activity (SWA) by modulating slow waves through closed‐loop auditory stimulation (CLAS) might provide a powerful non‐pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)‐mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration,

Abstract figure legend Sounds of different frequencies elicit spatially distinct patterns of neural activity within the inferior colliculus aligned to the tonotopic organization of afferent projections. Sound‐evoked neural responses can be visualized in awake mice that express fluorescent Ca2+ sensors.

Noise‐induced reduction and early recovery of superior paraolivary nucleus sound‐offset responses
Abstract figure legend Acoustic over‐exposure transiently disrupts auditory temporal processing in mouse superior paraolivary nucleus neurons. In control conditions, neurons exhibit robust sound‐offset (OFF) responses, which are abolished immediately following noise trauma, indicating impaired temporal encoding.

Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.
