A Homeostatic Photonic Device Integrating Vapor‐Regulated Thermo‐Optical Feedback Mechanisms
Advanced Functional Materials, EarlyView.An inorganic homeostatic photonic device is designed to autonomously regulate light, temperature, and vapor sorption through integrated positive and negative feedback mechanisms at multiple wavelengths. The device uses a graded mesoporous 1D photonic crystal coupled with a photothermal layer.

Research on the redshift evolution of luminosity function and selection effect of GRBs [PDF]
, 2015 We study the redshift evolution of the luminosity function (LF) and redshift selection effect of long gamma-ray bursts (LGRBs). The method is to fit the observed peak flux and redshift distributions, simultaneously. To account for the complex triggering algorithm of Swift, we use a flux triggering efficiency function.

Advanced Functional Materials, EarlyView.A novel polymer electrolyte membrane with a hyperbranched interpenetrating hydrogen bond network structure is developed. The unique structure of the hyperbranched polymer contributes to a high glass transition temperature exceeding 400 °C, enabling its operation at elevated temperatures for fuel cell applications.

Evidence consistent with the cosmological interpretation of quasar redshifts [PDF]
arXiv, 2000 In this letter, the old issue of whether redshifts of quasars are of cosmological origin is investigated. We make a plot of absorption redshifts versus emission redshifts for quasars with large amounts of data. Our study shows that, almost all absorption redshifts are smaller than the corresponding emission redshifts.

Photometric Redshifts of Quasars
The Astronomical Journal, 2001 We demonstrate that the design of the Sloan Digital Sky Survey (SDSS) filter system and the quality of the SDSS imaging data are sufficient for determining accurate and precise photometric redshifts (``photo-z''s) of quasars. Using a sample of 2625 quasars, we show that photo-z determination is even possible for z<=2.2 despite the lack of a strong ...

The Imprint of Neutrinos on Clustering in Redshift Space [PDF]
Astrophysical Journal, 2017 We investigate the signatures left by the cosmic neutrino background on the clustering of matter, CDM+baryons, and halos in redshift space using the HADES simulations.

Advanced Functional Materials, EarlyView.A strongly correlated electron system (SCES) exhibits pronounced insulating behavior due to Coulombic repulsion between cations, which generates a charge gap. This study investigates the tuning of the band structure in NiWO4‐based SCES via Cu doping at substitutional sites and Li doping at interstitial sites.

The Distance of GRB is Independent from the Redshift [PDF]
arXiv, 2008 Although it is acknowledged that GRB redshift is cosmological at present, but it in fact has never been confirmed. However, the fact is still unclear because which may be cosmological redshift (including possibly the host galaxy redshift or the background galaxy redshift) or the redshift results from gravity of neutron star; in other words, GRB ...

Advanced Functional Materials, EarlyView.Phosphorescent OLEDs suffer from efficiency roll‐off due to triplet‐polaron quenching (TPQ). This study demonstrates for a large set of host‐guest combinations a spectroelectrochemical method to measure the absorption of charged molecules, enabling determining TPQ Förster radii (2.5–4 nm) from the spectral overlap.
