Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Clinically Informed Intelligent Classification of Ovarian Cancer Cells by Label‐Free Holographic Imaging Flow Cytometry

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quantitative phase maps of single cells recorded in flow cytometry modality feed a hierarchical architecture of machine learning models for the label‐free identification of subtypes of ovarian cancer. The employment of a priori clinical information improves the classification performance, thus emulating the clinical application of liquid biopsy during ...

Recent Advances in Dielectric Chiral Metasurfaces

open access: yesAdvanced Physics Research, EarlyView.
This review article mainly focuses on the recent advances in dielectric chiral metasurfaces, which exhibit remarkable optical chirality. Many new physical conceptions will be introduced during the fast development of the dielectric chiral metasurfaces, such as chiral quasi‐BIC, chiral guided modes, and nonlocal metasurfaces.

Reviewing the Inclusion of Artists’ Holograms in the Permanent Collections of Fine Art Museums

open access: yesArts, 2019
Opening in 1976 with the exhibition, “Through the Looking Glass”, the Museum of Holography (MOH) emphasized from the beginning the importance of artistic holography with the inclusion of several holograms by artists whose primary practice was

Atom holography

open access: yes, 1999
We study the conditions under which atomic condensates can be used as a recording media and then suggest a reading scheme which allows to reconstruct an object with atomic reading beam.

Compact Monocular Video‐Ophthalmoscope to Measure Retinal Reflectance Changes to Flicker Light Stimuli

open access: yesJournal of Biophotonics, EarlyView.
This study presents a compact monocular VO that captures high‐frame‐rate retinal videos of the ONH during flicker light stimulation. The device demonstrated its ability to detect flicker‐induced changes in retinal parameters related to blood flow in healthy subjects, providing insights into temporal and spatial retinal variations.

Full‐color holographic image capture: Cholesteric liquid crystal circular polarizer combined with geometric phase lens reduces noise in self‐interference incoherent digital holography

open access: yesJournal of the Society for Information Display, EarlyView.
By using cholesteric liquid crystals as circular polarization filters in quarter‐waveplate condition GPL (QW‐GPL) based SIDH, a stable circular polarization state is ensured, which reduces color distortion and polarization noise, thereby significantly enhancing the reconstructed image quality in full‐color QW‐GPL‐based SIDH.
