Transient Study of Femtosecond Laser–Induced Ge2Sb2Te5 Phase Change Film Morphology
Micromachines, 2021 Femtosecond laser-induced crystallization and ablation of Ge2Sb2Te5 (GST) phase change film is investigated by reflectivity pump-probing technology. Below the ablation threshold, the face-centered cubic structure (FCC) state in the central area can be ...

First Detection of Near-Infrared Intraday Variations in the Seyfert 1 Nucleus NGC4395
, 2006 We carried out a one-night optical V and near-infrared JHK monitoring observation of the least luminous Seyfert 1 galaxy, NGC4395, on 2004 May 1, and detected for the first time the intraday flux variations in the J and H bands, while such variation was ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Continuous polarization–wavelength mapping with nonlocal metasurfaces
Light: Science & ApplicationsSimultaneous and continuous control over polarization and wavelength—two orthogonal and information-rich degrees of freedom—remains a central challenge in metasurface photonics, long hindered by intrinsic dispersion constraints and structural degeneracy.

Infrared spectroscopic diagnostics for Active Galactic Nuclei
, 2007 Infrared spectroscopy in the mid- and far-infrared provides powerful diagnostics for studying the emission regions in active galaxies. The large variety of ionic fine structure lines can probe gas conditions in a variety of physical conditions, from ...

Near-Infrared Spectra of Ultraluminous Infrared Galaxies [PDF]
The Astrophysical Journal, 1999 Near infrared spectra with resolution R ~ 1100 in the rest wavelength range 1.8-2.2 microns have been obtained for a complete sample of 33 ultraluminous infrared galaxies. Of the 33 objects observed, 2 show evidence of a central AGN through either a broad Paschen-alpha line or emission in the 1.963 micron fine structure of [Si VI].

PARP inhibitors induce a senescence phenotype in non‐small cell lung carcinoma cell lines
FEBS Open Bio, EarlyView.Talazoparib is the most potent inducer of senescence among different PARP1 inhibitors in human NSCLC cells. In the absence of PARP, no senescence phenotype was observed, demonstrating that PARP1 is necessary for the induction of senescence by this inhibitor.

Suppression for an intermediate phase in ZnSb films by NiO-doping
Scientific Reports, 2017 The structural evolution and phase-change kinetics of NiO-doped ZnSb films are investigated. NiO-doped ZnSb films exhibit a single-step crystallization process, which is different from that of undoped ZnSb.
