Beavers on Ice: Factors Influencing Emergence Phenology in Boreal Canada

Global Change Biology, Volume 32, Issue 4, April 2026.
Climate‐driven changes in ice phenology influence the timing of spring emergence of a non‐hibernating ice‐bound mammal, the North American beaver. ABSTRACT The influence of climate change on emergence phenology of hibernating mammals in northern latitudes is receiving increased attention, yet for freshwater semi‐aquatic mammals such as beavers, which ...

Magnetically Driven Spinodal Decomposition as the Origin of Magnetic Softness of CoFeNi‐Based Ferromagnetic High‐Entropy Alloys

ChemPhysChem, Volume 27, Issue 6, 27 March 2026.
Many CoFeNi‐based high‐entropy alloys are soft ferromagnets. Magnetic softness originates from nanostructure formed by spinodal decomposition, where CoFeNi FM nanodomains alternate with nanodomains of other elements. Spinodal decomposition is magnetically driven via the magnetic part of the Gibbs free energy, where the CoFeNi short‐range FM order ...

Systematic Study of PDMS Optical Waveguides for Pressure Sensing Using Design of Experiments

Journal of Applied Polymer Science, Volume 143, Issue 12, March 20, 2026.
A response surface methodology was used to systematically evaluate the impact of mix ratio and cure conditions on PDMS optical waveguide properties for pressure sensing. Mix ratio significantly influenced compression sensitivity, compressive modulus, and propagation loss, while cure temperature primarily affected refractive index.

Na4Ba9MnN3: A New Subnitridometalate with Trigonal Planar Anions [MnIIIN3]6−

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
The new subvalent nitridomanganate(III) Na4Ba9MnN3 contains structural elements known from ionic subnitridometalates as well as from intermetallic phases. In similarity to Ba3MnN3, isolated trigonal planar nitridomanganate(III) anions (MnN3)6−, coordinated by barium atoms represent the ionic region, while mixed barium‐sodium icosahedra known from ...

N‐Heterocyclic Tetrylenes with a 1,1′‐Ferrocenylene Backbone and Bis(2,4,6‐triisopropylphenyl)boryl N‐Substituents

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
Ferrocene‐based N‐heterocyclic tetrylenes [Fe{(η5‐C5H4)NBTrip2}2E](E = GePb; Trip = C6H2‐2,4,6‐iPr3)exhibit long EN and short BN bonds, in agreement with increased electrophilicity due to the ‐M effect of the N‐substituents, whose stericdemand prevents coordination of 4‐(dimethylamino)pyridine (DMAP) to theplumbylene PbII atom, but allows the ...

Ratios of Extinction Coefficient, Mass, and Surface Area to Backscatter Coefficient and Mass to Extinction Coefficient Derived From Balloon‐Borne Stratospheric Aerosol Size Distribution Measurements From 1989–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.
