Photopatternable PEDOT:PSS Hydrogels for High‐Resolution Photolithography
Advanced Science, EarlyView.A photosensitive biphasic conducting polymer hydrogel (PB‐CH) is rationally designed with PEDOT:PSS as the conductive phase and a light‐sensitive matrix as the mechanical phase. Such a PB‐CH offers a unique combination of excellent conductivity (≈30 S cm⁻¹), robust mechanical performance (with stretchability up to 50%), and high photopatternability ...

FIR/Submm Spectroscopy with Herschel: First Results from the VNGS and H-Atlas Surveys
Open Astronomy, 2011 The FIR/submm window is one of the least-studied regions of the electromagnetic spectrum, yet this wavelength range is absolutely crucial for understanding the physical processes and properties of the ISM in galaxies.

Are brightest halo galaxies central galaxies? [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 It is generally assumed that the central galaxy in a dark matter halo, that is, the galaxy with the lowest specific potential energy, is also the brightest halo galaxy (BHG), and that it resides at rest at the centre of the dark matter potential well. This central galaxy paradigm (CGP) is an essential assumption made in various fields of astronomical ...

Rapid BAL Variability: Re-Emerging Absorption
Frontiers in Astronomy and Space Sciences, 2017 We study BAL variations of SDSS J141955.28+522741.4 utilizing 32 epochs of spectroscopic observations from SDSS. We identify three individual BAL troughs for C iv and one BAL trough for Si iv.

266 E+A Galaxies Selected from the Sloan Digital Sky Survey Data Release 2: The Origin of E+A Galaxies [PDF]
Mon.Not.Roy.Astron.Soc. 357 (2005) 937, 2005 E+A galaxies are characterized as a galaxy with strong Balmer absorption lines but without any [OII] nor H$\alpha$ emission lines. The existence of strong Balmer absorption lines indicates that E+A galaxies have experienced starburst within recent one Gyr.
