Harnessing Optical Limiting in Saturable Absorbers for Reconfigurable Spectral Engineering of Ultrafast Fiber Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

Chain‐End Grafting of RAFT Polyelectrolyte Macroligands to Stabilize Near‐Infrared‐Emitting Gold Nanoclusters

open access: yesMacromolecular Rapid Communications, EarlyView.
Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Near 13% Efficient Semitransparent Cu(In,Ga)S2 Solar Cells With Band Gap of 1.6 eV on Transparent Back Contact

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This work demonstrates progress in the development of wide‐bandgap CIGS solar cells featuring a transparent back contact, for the application of top cell in tandem devices. A semitransparent device with a bandgap of 1.6 eV achieved a power conversion efficiency of nearly 13% on an ITO back contact.

More π, less Gap: Band Gap Tuning in Hybrid Antimony Halide Charge Transfer Semiconductors

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Extending the π‐conjugation of the organic cation from bipyridinium to phenanthrolinium in hybrid antimony chloride charge transfer semiconductors reduces the band gap from 2.6 to 2.1 eV. This demonstrates that modifying the organic cation's π‐system enables band gap tuning in hybrid charge transfer semiconductors.

Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability

open access: yesAndrology, EarlyView.
ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

Simulation of Photomultiplier Response

open access: yes, 1999
A code for simulation of photomultipier response was created and tested for a broad range of photomultiplier gain, A reasonably good agreement between the experimental R5900 spectra and simulated ones was achieved.
