Artificial Synaptic Device Based on Self‐Aligned c‐In2O3 TFTs With an Ultrathin MgO Interlayer
A coplanar synaptic thin‐film transistor based on crystalline In2O3 is demonstrated using a PECVD SiO2 gate insulator and an ultrathin MgO interlayer. The MgO interlayer suppresses excessive carrier density and may facilitate proton‐related interfacial polarization, resulting in stable counterclockwise hysteresis and synaptic behavior.

Superfluorescence is a cooperative emission process not scaling with sample volume. Amplified spontaneous emission is a collective process scaling with sample volume and is enhanced by waveguiding. Both manifest in a narrow emission peak. Choosing the right substrate suppresses waveguiding and demonstrates that the emission feature observed in PEA ...

Proton‐Radiation‐Tolerant Silicon Photonic Charge Sensor for Spacecraft Applications
A photonic charge sensor based on silicon photonic crystal waveguides is evaluated under proton irradiation to clarify radiation‐induced optical absorption during operation. The study quantitatively determines absorption increase at 20 keV and demonstrates retained spacecraft‐potential sensing after high‐fluence exposure, providing a quantitative basis

A high‐performance strain‐compensated InGaAs/GaAsP superlattice SWIR photodetector was successfully grown by MOCVD on a scalable 100 mm GaAs platform. Combining excellent structural quality with strong optoelectronic performance, the device delivers a low dark current density of 2.3 × 10−7 A/cm2 and a detectivity of 1.9 × 1011 Jones at 1100 nm ...

Molecular filming: A director's grammar for visualizing chemistry in motion
Molecular filming names the practice, not just the product, of ultrafast structural science. In deliberate analogy to molecular editing, which rewrites connectivity in space, molecular filming records geometry in time, assembling time‐ordered structural frames into a movie of atomic motion and recasting the field as a grammar of directorial choices ...

Donor–Acceptor Solid Molecular Catalysts for Photocatalytic Hydrogen Peroxide Production
Organic terpyridine‐based donor–acceptor photocatalysts: Solid molecular catalysts enable efficient hydrogen peroxide synthesis from water and ambient oxygen under visible light. Systematic variation of donor and acceptor moieties, combined with optoelectrical characterization, allows structure–activity relationships to be derived.

Characterization of Pulmonary Functional Abnormalities in Systemic Sclerosis Using Xenon MRI
ABSTRACT Background Xenon MRI is increasingly used to evaluate patients with interstitial lung disease (ILD) and pulmonary hypertension (PH), both of which are common manifestations of systemic sclerosis (SSc). As such, Xe‐MRI may be suited to interrogate lung function impairment in SSc.

A local‐biasing system using AFM induces site‐specific threshold switching in Ge0.17Te0.83 films, enabling direct observation of crystalline/amorphous interface formation. First‐principles calculations reveal that this structural change induces Te 5p‐dominated mid‐gap states and electric field‐enhanced charge redistribution.
