Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

On the Phase Width of MgZn2/KHg2‐Type Intermetallics AIIMg2−xZnx (A = Ca, Sr, Ba) and the New Compounds (Sr/Ba)11Mg16Zn6 and Ba6Mg2.8Zn8.2

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The continuous, but obviously geometrically limited Mg↔Zn substitution in members of the two basic structures types of intermetallics, the KHg2‐type dizincides, and the MgZn2/Laves‐type dimagnesidesof Ca, Sr, and Ba exhibit a large phase widths for CaMg2 only. Instead, the larger alkaline‐earth elements form the “optimized” complex compounds A11Mg16Zn6

Exploring the Landscape of MgO Polymorphs: Stability and the Electronic Band Gap of Promising Candidates

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
In this study, we have investigated possible predicted polymorphs of magnesium oxide (MgO) with respect to their thermodynamic and kinetic stability, as well as their electronic properties, focusing on the possibility of tuning the band gap of the material.

The Crystal Structures of High‐ and Low‐Temperature Silver Pyrophosphate: Structural Instability and Its Consequences

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The crystal structures of the high‐temperature and low‐temperature phases of silver pyrophosphate are reported. The structural results are complemented by thermal analysis, vibrational and 31P‐MAS‐NMR spectroscopy studies, and density functional theory calculations.

Zero‐Current Switching Based Model Predictive Control of a Double‐Extended Overlapped Alternate Arm Converter Used in the VSC–HVDC System

open access: yesHigh Voltage, EarlyView.
ABSTRACT The alternate arm converter (AAC) is one of the most efficient multilevel topologies based on voltage source converters (VSCs), which has recently gained attention in various applications, particularly in high voltage direct current (HVDC) systems.

Comprehensive Design and Experimental Validation of 30 kV Ultra‐Fast Flexible Controllable Arresters for HVDC Systems

open access: yesHigh Voltage, EarlyView.
ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.
