Hydrothermally Carbonized Corncob‐Derived Hard Carbon Anodes for High‐Performance Sodium‐Ion Batteries

open access: yesChemElectroChem, Volume 12, Issue 24, December 8, 2025.
A low‐surface‐area hard carbon anode is synthesized from corncob waste through a two‐step process. The material treated at the highest temperature exhibits reduced irreversible reactions and enhances sodium storage performance, due to optimized porosity and structural order, highlighting a sustainable strategy for advanced sodium‐ion battery materials.

Migratory Songbirds as Potential Ectozoochorous Protist Dispersal Vectors

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We demonstrate that migratory songbirds carry diatoms (Bacillariophyta) in their plumage, revealing an unexpected avian–algal association. All seven bird specimens we examined contained diatoms—224 frustules representing 25 genera and 9 orders, primarily freshwater, benthic pennates—some retaining chloroplasts prior to digestion and mounting (implying ...

Bioaccumulation of silicon and enhancement of cannabis inflorescence yield from fertiliser supplementation with the biostimulants silicate and phosphite

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 53, Issue 4, Page 1261-1273, December 2025.
ABSTRACT Two fertiliser supplements which have become established within the agricultural sphere for their promotion of resistance to biotic and abiotic stressors, are the non‐nutritive biostimulants silicon (Si) and phosphite (Phi). However, within the cannabis sphere, Phi has had limited establishment, and Si is purported to be non‐bioavailable in ...
