Techniques and Review of Absolute Flux Calibration from the Ultraviolet to the Mid-Infrared [PDF]
The measurement of precise absolute fluxes for stellar sources has been pursued with increased vigor since the discovery of the dark energy and the realization that its detailed understanding requires accurate spectral energy distributions (SEDs) of redshifted Ia supernovae in the rest frame.

Calibration of ultraviolet, mid-infrared and radio star formation rate indicators [PDF]
We present calibrations for star formation rate indicators in the ultraviolet, mid-infrared and radio continuum bands, including one of the first direct calibrations of 150 MHz as a star formation rate indicator. Our calibrations utilize 66 nearby star forming galaxies with Balmer decrement corrected H-alpha luminosities, which span 5 orders of ...

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

Pincer‐Type Pt(II)‐NHC Antibody‐Drug Conjugate for HER‐2‐Targeted Chemoimmunotherapy
The antibody‐drug conjugate Trastuzumab‐Pt1 has demonstrated successful development as a targeted therapeutic strategy for human epidermal growth factor receptor (HER‐2) high‐expression tumors. This innovative approach enables the efficient delivery of the cytotoxic payload Pt‐1 to mitochondria, thereby synergistically inducing necroptosis and ...

Carbon and Oxygen Galactic Gradients: Observational Values from HII Region Recombination Lines [PDF]
We present results of deep echelle spectrophotometry of eight Galactic HII regions located at Galactocentric distances between 6.3 and 10.4 kpc. The data have been taken with the Very Large Telescope (VLT) Ultraviolet Echelle Spectrograph (UVES) in the 3100 to 10360 A range.

M4-18: The planetary nebula and its WC10 central star [PDF]
We present a detailed analysis of the planetary nebula M4-18 (G146.7+07.6) and its WC10-type Wolf-Rayet central star, based on high quality optical spectroscopy (WHT/UES, INT/IDS, WIYN/DensPak) and imaging (HST/WFPC2).
