Community‐driven variations in snow algae color modulate snow albedo reduction

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1739-1752, February 2026.
Summary Snow algae blooms visibly alter snow color and surface energy balance, yet the biological basis of this variability remains unclear. We investigated how pigment composition and community structure shape the optical properties of snow algae blooms of distinct colors – red, orange, and green – co‐occurring within the same snowfield in Glacier ...

Estimating Soil Electrical Parameters in the Canadian High Arctic From Impedance Measurements of the MIST Antenna Above the Surface

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The MIST experiment aims to detect the cosmological 21‐cm signal through sky observations at 25–125 MHz using a wide‐beam antenna. The antenna is mounted above the soil and the beam characteristics are highly dependent on the soil's electrical properties.

Exploiting CO2‐Derived Carbon in Lithium‐Ion Batteries

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
In this work, a carbon nanomaterial (CNM) extracted from CO2 reduction treatment is used as the conductive additive in lithium‐ion battery graphite anodes and LiFePO4 cathodes. The electrodes are produced by casting, using both sodium alginate as a green, water‐soluble, alternative binder.

Electron Channeling Contrast Imaging for the Characterization of Dislocations in III−V Thin Films on Silicon (001)

open access: yesphysica status solidi (a), Volume 223, Issue 2, January 2026.
Defect characterization plays a crucial role in semiconductor research, yet the development of fast, cheap, and nondestructive tools remains challenging. This work applies electron channeling contrast imaging (ECCI) to III–V thin films on silicon, examining beam parameters and diffraction conditions.
