Soil Texture and Chemical Properties Influence Arbuscular Mycorrhizal Fungi Abundance, Diversity, and Richness in East African Rangelands

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT Rangeland degradation in East Africa threatens soil biodiversity. Yet the diversity of native arbuscular mycorrhizal fungi (AMF) remains underexplored in this region, despite their central role in nutrient cycling, soil aggregation, and ecosystem functioning.

A Practical Superconducting DC Dynamo for Charging Conduction-Cooled HTS Magnet

Energies
At present, HTS magnets cannot operate in the real closed-loop persistent current mode due to the existence of joint resistance, flux creep, and AC loss of the HTS tape. Instead of using a current source, HTS flux pumps are capable of injecting flux into

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

Advanced Materials Technologies, Volume 11, Issue 7, 6 April 2026.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Prediction of Nonsinusoidal AC Loss of Superconducting Tapes Using Artificial Intelligence-Based Models

IEEE Access, 2020
Current is no longer sinusoidal in modern electric networks because of widespread use of power electronic-based equipments and nonlinear loads. Usually AC loss is calculated for pure sinusoidal current, while it is no longer accurate when current is ...

Mechanism of Solid Solution‐Driven Texture Induced by Ag Doping in YBCO Superconductor

Advanced Science, Volume 13, Issue 22, 17 April 2026.
Ag‐doped YBCO with a designed concentration gradient is produced by dual‐material co‐extrusion and freeze‐drying. During annealing, Ag+ ions diffuse into Y123, substituting for Cu(1) and inducing c‐axis relaxation. This leads to the formation of [001]‐oriented YBCAO, creating a coherent interface that templates the textured growth of Y123. Consequently,
