Ultraviolet spectrophotometry of degenerate stars

The Astrophysical Journal, 1979
Observations of one helium- and three hydrogen-atmosphere degenerates made with the International Ultraviolet Explorer are discussed. Fluxes in the UV give temperatures in good accordance with those determined from the ground and from the ANS satellite data.

Ag‐Cu Nanoarchitecture for Enhanced LSPR Absorption: the Role of Surface Roughness and near‐field Interactions

Advanced Materials Interfaces, EarlyView.
This study investigates the plasmonic properties and biosensing capabilities of a nanocomposite incorporating Cu and Ag nanoparticles for detecting anti‐DbpA antibodies associated with Lyme disease. The enhanced LSPR response is explained through FDTD simulations of Cu–Ag near‐field interactions and increased surface roughness.

The New Generation Atlas of Quasar Spectral Energy Distributions from Radio to X-rays [PDF]

, 2011
We have produced the next generation of quasar spectral energy distributions (SEDs), essentially updating the work of Elvis et al. (1994) by using high-quality data obtained with several space and ground-based telescopes, including NASA's Great ...

Aqueous Synthesis of Poly(ethylene glycol)‐Amide‐Norbornene‐Carboxylate for Modular Hydrogel Crosslinking

Advanced Materials Interfaces, EarlyView.
An all aqueous synthesis of poly(ethylene glycol)‐amide‐norbornene‐carboxylate (PEGaNBCA) is developed via reacting carbic anhydride with amino‐terminated PEG. PEGaNBCA is readily crosslinked into hydrogels by click chemistries. PEGaNBCA crosslinked thiol‐norbornene hydrogels are hydrolytically stable but can be rendered hydrolytically labile through ...

Properties of the ionized gas in HH 202 – II. Results from echelle spectrophotometry with Ultraviolet Visual Echelle Spectrograph [PDF]

, 2009
We present results of deep echelle spectrophotometry of the brightest knot of the Herbig– Haro object HH 202 in the Orion Nebula – HH 202-S – using the Ultraviolet Visual Echelle Spectrograph in the spectral range from 3100 to 10 400 A. The high spectral

High‐throughput Photocatalytic Reactor With in Operando Characterisation for Fast Screening of Materials for the Photodegradation of Water‐Borne Pollutants

Advanced Materials Interfaces, EarlyView.
A novel fast‐screening photocatalytic reactor system (FaS‐PhoReS) using terrestrial sunlight is able to measure the in operando photodegradation of 32 samples at once, and does not suffer from the common problem of sample evaporation. Four photostable 12 dyes are used to investigate the photocatalytic performance of TiO2 and ZnO samples in both film ...

Improvement of Electrochromic Stability of Viologen‐Based Ionic Gel by Layered Metal–Organic Frameworks

Advanced Materials Interfaces, EarlyView.
Metal–organic framework doped viologen‐based ionogel electrochromic device demonstrates superior performance including homogeneous chromatic transition, enhanced coloration efficiency, and exceptional cycling stability. These advancements originate from dual mechanisms: 1) physical confinement effect effectively suppressing viologen molecular ...

The high-field polar RX J1007.5-2017 [PDF]

, 2012
We report optical and X-ray observations of the high-field polar RXJ1007.5-2017 performed between 1990 and 2012. It has an orbital period of 208.60 min determined from the ellipsoidal modulation of the secondary star in an extended low state.
