High‐Resolution Electron‐Beam Poling of X‐Cut Lithium Niobate Thin Films

open access: yesAdvanced Optical Materials, EarlyView.
A new periodic poling technique using electron beams to create stable, high‐quality ferroelectric patterns is developed in x‐cut thin‐film lithium niobate (TFLN). The method works at room temperature with both standard and MgO‐doped materials, affords ferroelectric domain pitches as small as 375 nm, and lends itself to seamless integration with state ...

Determination of Strange Sea Quark Distributions from Fixed-target and Collider Data

open access: yes, 2014
We present an improved determination of the strange sea distribution in the nucleon with constraints coming from the recent charm production data in neutrino-nucleon deep-inelastic scattering by the NOMAD and CHORUS experiments and from charged current ...

Strong and Weak Coupling Nanophysics with Free Electron Beams

open access: yesAdvanced Optical Materials, EarlyView.
This paper focuses on a short review of the study of the coupling between optical excitations at the nanometer scale, made possible by recent advances in free electron beam spectroscopies. In particular, plasmon–plasmon, plasmon–exciton, and plasmon–phonon couplings are reviewed. Abstract The work of Luis M.

Strain‐Induced Optical and Molecular Transformations in Poly(Ethylene Terephthalate) Films for Organic Electronic Applications

open access: yesAdvanced Photonics Research, EarlyView.
This study explores how mechanical strain affects the optical and molecular properties of poly(ethylene terephthalate) (PET) films, crucial for flexible electronics. Using UV–Vis and Raman spectroscopy, it reveals strain‐induced changes in transparency and vibrational modes. Findings provide insights into optimizing PET‐based devices like organic solar

Precision Diagnostics in Sports‐Related Traumatic Brain Injury: Pathophysiology, Biomarker Development and Emerging Technologies

open access: yesAdvanced Sensor Research, EarlyView.
Sports‐related traumatic brain injuries (TBIs) remain underdiagnosed, within amateur athletic cohorts. This review critically synthesises recent advancements in AI‐assisted neuroimaging, blood‐based biomarker profiling, wearable biosensing platforms for early detection, injury stratification, and longitudinal surveillance of TBIs.
