2‐line Ferrihydrite Enhance Microbial Synthesis of Plant Biostimulants in Composted Biosolid by Regulating Phyla Pseudomonadota and Actinomycetota

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
This study explores how iron and manganese oxides transform sewage sludge into plant biostimulants during composting. Non‐targeted identification reveals the main species of plant biostimulants. Metagenomic analysis reveals that 2‐line ferrihydrite specifically enriches microbial genes for biosynthesis, boosting plant‐growth promoters.

Perspective on the Technology Status of Chemical Hydrogen Carriers for Ship‐Based Energy Import

open access: yesElectrochemical Science Advances, Volume 6, Issue 1, February 2026.
ABSTRACT The transport of hydrogen for the import of renewable energy will play an important role for the highly industrialized regions in Europe to meet their energy needs. As the storage and transportation of neat hydrogen comes with considerable downsides with respect to energy density and infrastructure compatibility, chemical hydrogen carriers are

Criss-cross Cycloadditions on Ketazines Derived from Alicyclic Ketones

open access: yesMolecules, 2006
The reactivity of alicyclic ketazines in criss-cross cycloadditions was investigated. They react with potassium cyanate and ammonium thiocyanate in the presence of acetic acid to form spirocyclic perhydro[1,2,4]triazolo[1,2-a][1,2,4]triazole-1,5-diones ...

Thermally stable polyimides from solutions of monomeric reactants [PDF]

open access: yes, 1971
Monomer solutions have high solubility and low solution viscosity. Since monomers are shipped in powder form and reaction to polyimide-acid prepolymer is omitted, the cost is low and handling is ...
