How much biotic nativeness matters across human demographic groups

open access: yesConservation Biology, EarlyView.
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Experimental methods in chemical engineering: Electrospinning

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 2, Page 556-568, February 2026.
Abstract Electrospinning produces micro‐ and nanofibres by forcing a polymeric solution through a fine needle in an electric field that produces a filament that accumulates onto a collector plate. The fibre morphology depends on solution properties, distance between needle and plate, feed rate, and electric field intensity.

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.

Unsymmetrical β‐Fused Blatter Radical Zinc Phthalocyanines

open access: yesChemistry – A European Journal, Volume 32, Issue 4, 23 January 2026.
Herein, we report the first synthesis of a new class of β‐fused Blatter–Zn phthalocyanines featuring a persistent radical π‐system, π–π‐driven crystal packing, and SOMO‐centered redox behavior. Single‐crystal X‐ray diffraction shows packing motifs dominated by centrosymmetric π‐π dimers.

Heterobimetallic Pt(II) Complexes Supported by 1,8‐Naphthyridine Ligands Confirm the Rotation of C6F5 Groups about the Pt−C Bond

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
You Spin Me Round. The ligand 1,8‐naphthyridine is able to stabilize heterobimetallic complexes containing Pt(II)→M (M = Ag, Cu) donor–acceptor bonds, in which the rotation of the C6F5 ligands in solution can be stopped at low temperature. The ligand 1,8‐naphthyridine (napy) exhibits a rich coordination chemistry arising from the disposition of its two

Bi‐Functional Topospecific Nanoparticles to Promote Immune‐Tumor Cell Engagement as A New Immunotherapeutic Strategy

open access: yesAdvanced Materials, Volume 38, Issue 2, 8 January 2026.
A Janus‐engineered nanoplatform (J‐pHLIP‐PD1), featuring separate tumor‐ and immune‐targeting faces, bridges melanoma cells and cytotoxic T lymphocytes using toposelective pHLIP and anti‐PD‐1 presentation. This strategy elicits robust antitumor responses, promotes immunogenic tumor cell death, suppresses lung metastasis in vivo, and provides a modular,

Application of Gamification Mechanics to Computational Fluid Dynamics Seminars Using Genially

open access: yesComputer Applications in Engineering Education, Volume 34, Issue 1, January 2026.
ABSTRACT This work describes the procedure for the gamification of Computational Fluid Dynamics (CFD) seminars, with the aim of increasing student motivation and simplifying the learning and acquisition of skills related to the use of CFD tools. The seminar activity is divided into two parts: (i) autonomous work along the semester, in which students ...

“Seeing” Periodic Structures Emerge: Ultrafast Bright‐ and Dark‐Field Microscopy During Femtosecond Laser Interference Patterning of Silicon

open access: yesLaser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
We report an ultrafast bright‐ and dark‐field pump‐probe microscopy technique combined with an interference patterning system to imprint amorphous and ablative line‐like structures with micrometer period in crystalline silicon using single femtosecond laser pulses.
