Superionic Disulfonic Acid Polymers
Advanced Functional Materials, EarlyView.A strategy is presented to enhance the mechanical and ion transport properties of acid‐functionalized polymers through controlled polymerizations of precisely designed disulfonic acid monomers with well‐defined functional group arrangements. This approach allows for fine control over molecular interactions, and unexpected hydrophobic characteristics ...

Origins And Evolution Of Galactic Type Diversity
International Scholastic Journal of Science, 2016 A study is presented into the origins of galactic type diversity and galaxy evolution through investigating the relationship between representative galaxy color index u-v and redshifts.

, 2020 Can redshift errors bias our measurement of the Hubble constant? This talk outlines some common errors in redshift measurements, in particular some common theoretical errors that should be avoided, and assesses how such errors can impact cosmological parameter inferences.

The Complete Calibration of the Color–Redshift Relation (C3R2) Survey: Survey Overview and Data Release 1 [PDF]
, 2017 A key goal of the Stage IV dark energy experiments Euclid, LSST, and WFIRST is to measure the growth of structure with cosmic time from weak lensing analysis over large regions of the sky. Weak lensing cosmology will be challenging: in addition to highly

Advanced Functional Materials, EarlyView.Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Testing the accuracy of clustering redshift with simulations [PDF]
, 2017 We explore the accuracy of the clustering-based redshift inference within the MICE2 simulation. This method uses the spatial clustering of galaxies between a spectroscopic reference sample and an unknown sample. The goal of this study is to give a preview of the redshift accuracy one can reach with this method.

The Nonlinear Redshift Space Power Spectrum: Omega from Redshift Surveys
, 1995 We examine the anisotropies in the power spectrum by the mapping of real to redshift space. Using the Zel'dovich approximation, we obtain an analytic expression for the nonlinear redshift space power spectrum in the distant observer limit.

Advanced Functional Materials, EarlyView.This study demonstrates the stability and Raman signal enhancement effects of Au@h‐BN nanoparticles in an alkaline electrolyte on. A comparison between conventional SiO2 and h‐BN shells reveals that the h‐BN core‐shell structure provides superior stability and enhanced Raman intensity over multiple cyclic voltammetry cycles.

On the Number of Galaxies at High Redshift
Galaxies, 2015 The number of galaxies at a given flux as a function of the redshift, z, is derived when the z-distance relation is non-standard. In order to compare different models, the same formalism is also applied to the standard cosmology.

Intrinsic Redshifts in QSOs Near NGC 6212 [PDF]
arXiv, 2003 The high number of QSOs around NGC 6212 allows a correlation analysis to be carried out between their redshift distribution and the redshift distributions predicted by intrinsic redshift models. We find no correlation between the QSO redshift distribution and the intrinsic redshifts predicted by Karlsson's log(1+z) = 0.089 relation.
