Small-scale solar surface magnetism [PDF]

open access: yesarXiv, 2021
This contribution to "Solar Magnetic Variability and Climate" reviews small-scale magnetic features on the solar surface, in particular the strong-field but tiny magnetic concentrations that constitute network and plage and represent most magnetism outside sunspots and filaments.

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

open access: yesAdvanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Domino Effects in the Earth System -- The potential role of wanted tipping points [PDF]

open access: yesarXiv, 2019
Vital parts of the climate system, such as the West Antarctic Ice Sheet, are at risk even within the aspired aims of the Paris Agreement to limit global temperature rise to 1.5 -- 2{\deg}C. These so-called natural tipping elements are characterized by rapid qualitative shifts in their states once a critical threshold, e.g., of global mean temperature ...

Climate Ready Great Lakes Cities [PDF]

open access: yes, 2015
Rising out of the strategic alliance between the National Oceanic and Atmospheric Administration (NOAA) and the Great Lakes and St. Lawrence Cities Initiative (GLSLCI), the motivating goal of this 13- month project was to create a more resilient Great ...

The role of sustainability and sustainable development in climate change mitigation and adaptation [PDF]

open access: yes
Today, the best way to discern the interlinkages between climate change and sustainability and/or sustainable development is the United Nations (UN) Sustainable Development Goal (SDG) 13—Climate Action framework.

CALPHAD‐Guided Prediction and Interpretation of Phase Formation in Ta–Mo–Cr–Ti–Al Refractory High‐Entropy Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This study designs Ta–Mo–Cr–Ti–Al refractory high‐entropy alloys with a disordered body‐centered‐cubic A2 crystal structure aiming for improved ductility, lower density, and oxidation resistance. Four alloy compositions are identified by thermodynamic calculations.

The various forms of anger about climate change in Australia and their relations with self-reported actions, intentions, and distress [PDF]

open access: yes
Action on societal issues is often precipitated by feelings of anger. This has been demonstrated reliably for responses to social inequality, but less for other issues.

Influence of Heat Treatment on Microstructure and Mechanical Properties at Elevated Temperatures of Nonweldable Ni‐Based Alloy Printed by Fused Filament Fabrication

open access: yesAdvanced Engineering Materials, EarlyView.
The fused filament‐fabricated MAR‐M247 alloy without hot isostatic pressing shows the lowest porosity of 4%. Heat treatment at 1220 °C produces coarse precipitates and carbides. Specimens heat‐treated at 1220 °C exhibit higher tensile strength (683 MPa) and elongation (10%) at room temperature.
