Advanced Engineering Materials, EarlyView.This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...

The Milbank Quarterly, 2014 When reviewing major public health initiatives over the past century, it is amazing to see how often beliefs, policies, and scientific fact have changed. A policy or notion deemed acceptable by one generation might be denigrated and avoided by a subsequent one; a product or practice once considered safe, if not entirely healthy, might later emerge as ...

Holonomy corrections to the cosmological primordial tensor power spectrum
, 2008 Loop quantum gravity is one of the leading candidate theory to non-perturbatively quantize gravity. In this framework, holonomy corrections to the equation of propagation of gravitons in a FLRW background have been derived.

Semiclassical scalar propagators in curved backgrounds: formalism and ambiguities
, 2007 The phenomenology of quantum systems in curved space-times is among the most fascinating fields of physics, allowing --often at the gedankenexperiment level-- constraints on tentative theories of quantum gravity.

Synthesized grain size distribution in the interstellar medium [PDF]
, 2012 We examine a synthetic way of constructing the grain size distribution in the interstellar medium (ISM). First we formulate a synthetic grain size distribution composed of three grain size distributions processed with the following mechanisms that govern

Advanced Engineering Materials, EarlyView.A novel approach for alloy development in laser powder bed fusion is introduced. Instead of producing massive samples of one composition at a time, prepressed powder bed samples produced from powder mixtures are processed. Guidelines for the selection of precursor powders are developed.
