Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Policy design and state capacity in the COVID-19 emergency in Italy: if you are not prepared for the (un)expected, you can be only what you already are

Policy & Society, 2020
Italy was the first large epicentre of the COVID-19 pandemic in the Western world. Since the country has not had any serious experience with this kind of disease in recent decades, its response has been indicative of a first reaction to an (un)known and (

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Does the proposed CAP reform allow for a paradigm shift towards a greener policy?

Spanish Journal of Agricultural Research, 2020
Aim of study: The paper explores whether the legislative proposal for the EU Common Agricultural Policy (CAP) after 2021 and the novelty of comprehensive strategic planning at Member State (MS) level can bring about a greener, more multifunctional policy

Innovation as a community-spanning process: strategies to handle path dependency. [PDF]

In this paper, we further develop and apply the notions of path creation and path dependency during technological innovation processes. The process of technological innovation is portrayed as an activity of spanning boundaries between and across ...

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

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 ...

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

Advanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Justice Delayed: An Analysis of Local Proposals for Black Reparations

RSF: The Russell Sage Foundation Journal of the Social Sciences
In this article, I document and analyze all municipal, state, and county-level efforts for Black reparations in the United States. Most efforts resemble H.R. 40’s exploratory commission model, possibly due to policy path dependency.

Path-dependent entropy production [PDF]

Journal of the Korean Physical Society, 2015
A rigorous derivation of nonequilibrium entropy production via the path-integral formalism is presented. Entropy production is defined as the entropy change piled in a heat reservoir as a result of a nonequilibrium thermodynamic process. It is a central quantity by which various forms of the fluctuation theorem are obtained.
