Temporal changes in avian abundance in aspen-dominated boreal mixedwood forests of central Saskatchewan, Canada

Avian Conservation and Ecology, 2018
The boreal forest provides important breeding habitat for many migratory songbirds; however, changes in disturbance regimes have led to concern for populations breeding there. Monitoring data to track changes in boreal forest bird populations are scarce.

Development of Aluminum Scandium Alloys for Hydrogen Storage Valves

Advanced Engineering Materials, EarlyView.
Different aluminum alloy series and various aluminum‐scandium alloys with differing Sc and Zr levels are evaluated for use in hydrogen storage valve production. The alloys undergo hardness testing, optical microscopy, and tensile strength analysis, with hardening behavior studied under varying conditions.

Impact of Various Rotary Friction Welding Process Parameters on the Mechanical Properties of a Steel–Aluminum Joint

Advanced Engineering Materials, EarlyView.
Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.

Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

Weather- and climate-driven power supply and demand time series for power and energy system analyses

Scientific Data
Reaching net-zero carbon emissions requires large shares of intermittent renewable energy and the electrification of end-use consumption, such as heating, making the future energy system highly dependent on weather variability and climate change. Weather
