Polypept(o)ide-Based Core-Shell Bottlebrush Polymers: A Versatile Platform for Drug Encapsulation. [PDF]
Macromol BiosciThis study developed polypept(o)ide‐based core–shell brushes (CSBs) with tunable sizes (Rh: 17–70 nm) for hydrophobic drug delivery. CSBs achieved 10% dasatinib loading through π–π interactions, enabling sustained release over 72 h. Notably, CSB‐dasatinib complexes showed comparable cell viability reduction to the free drug in U‐87 MG cells ...

Characterizing Quasar C iv Emission-line Measurements from Time-resolved Spectroscopy [PDF]
, 2020 We use multiepoch quasar spectroscopy to determine how accurately single-epoch spectroscopy can locate quasars in emission-line parameter space in order to inform investigations where time-resolved spectroscopy is not available.

The Astrophysical Journal, 2005 A new generation of sensitive X-ray measurements are indicating that the existence of X-ray attenuation column densities, NH > 1024 cm-2, is quite common among broad absorption line quasars (BALQSOs). This is significant to the geometry of the broad absorption line (BAL) outflow.

First results from high redshift quasar searches in VIKING [PDF]
, 2012 This thesis presents the discovery of the first luminous z & 6.5 quasars in the VISTA kilo-degree Infrared Galaxy Survey (VIKING). After some basic quality control, quasar selection is investigated via use of initial data supplementedwith ...

The Astrophysical Journal Supplement Series, 1997 We have obtained a high signal-to-noise (30 ? S/N ? 70), high-resolution (FWHM = 20 km s-1) spectrum of the radio-quiet QSO HS 1700+6416 (zem = 2.72) with the echelle spectrograph on the Kitt Peak National Observatory 4 m telescope. We detect 13 metal systems in the optical spectrum of this QSO, including six systems with associated optically thin ...

THE DISAPPEARANCE OF A NARROW Mg II ABSORPTION SYSTEM IN QUASAR SDSS J165501.31+260517.4
, 2013 In this paper, we present for the first time the discovery of the disappearance of a narrow Mg II lambda lambda 2796, 2803 absorption system from the spectra of the quasar SDSS J165501.31+260517.4 (z(e) = 1.8671).
