Advanced Engineering Materials, EarlyView.AlCrFeCoNi high entropy alloy coating is applied on steel using electrospark deposition. The microstructure evolution and phase transformation of the as‐deposited and heat‐treated coatings is characterized and discussed. Reduced microhardness and yield strength are measured after heat treatment.

The Formation Rate and Luminosity Function of Fast Radio Bursts
The Astrophysical Journal LettersFast radio bursts (FRBs) are millisecond-duration flashes with unknown origins. Their formation rate is crucial for unveiling physical origins. However, the luminosity and formation rate are degenerate when directly fitting the redshift distribution of ...

The faint end of the galaxy luminosity function
, 2002 We present and discuss optical measurements of the faint end of the galaxy luminosity function down to M_R = -10 in five different local environments of varying galaxy density and morphological content. The environments we studied, in order of decreasing

The luminosity function of quasars
The Astrophysical Journal, 1995 We propose a new evolutionary model for the optical luminosity function of quasars. Our analytical model is derived from fits to the empirical luminosity function estimated by Hartwick and Schade and Warren, Hewett, and Osmer on the basis of more than 1200 quasars over the range of redshifts 0 approximately less than z approximately less than 4.5.

The galaxy luminosity function at z ≃ 6 and evidence for rapid evolution in the bright end from z ≃ 7 to 5 [PDF]
, 2014 We present the results of a search for bright (-22.7 5. We calculate the bright end of the rest-frame Ultra-Violet (UV) luminosity function (LF) at z ~ 6.

Advanced Engineering Materials, EarlyView.This work applies High‐Speed Nanoindentation to study multi‐material transitions in powder bed fusion–electron beam melting components. The aim is to assess the mechanical gradients and interfacial behavior between American iron and steel institute 316L stainless steel and V4E tool steel in additively manufactured structures.

Galaxy UV-luminosity function and reionization constraints on axion dark matter [PDF]
, 2014 If the dark matter (DM) were composed of axions, then structure formation in the Universe would be suppressed below the axion Jeans scale. Using an analytic model for the halo mass function of a mixed DM model with axions and cold dark matter, combined ...

Advanced Engineering Materials, EarlyView.Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...
