Recent Advances of Nanomaterials in Electrochemical Enzyme‐Free Glucose Sensors

open access: yesFood Bioengineering, Volume 4, Issue 4, Page 511-545, December 2025.
This review systematically surveys electrochemical nonenzymatic glucose sensors published between 2020 and 2024. They are classified into transition metal‐derived nanomaterials, carbon‐based nanocomposites and polymeric materials. Their sensor design, analytical parameters and fabrication technologies are detailedly summarized, along with the ...

Systematical assessment of phase equilibria and thermodynamic properties in the RE (rare earth metals)—Cu binary systems

open access: yesMaterials Genome Engineering Advances, Volume 3, Issue 4, December 2025.
Seven RE–Cu (RE = Ce, Pr, Sm, Eu, Tb, Er, and Lu) binary systems were optimized thermodynamically using the CALPHAD method. Phase equilibria and thermodynamic properties of 13 RE–Cu (RE = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, and Lu) binary systems were examined systematically.

A review of grass species yields and growth rates in Northland, New Zealand

open access: yesNew Zealand Journal of Agricultural Research, Volume 68, Issue 6, Page 1440-1463, December 2025.
ABSTRACT Pastoral farming is a major land use in New Zealand's Northland region, with 3,171 farm holdings and a total area of 637,500 hectares in 2022. The region's pasture grasses include temperate (C3) and subtropical and tropical (C4) grasses which support dairy, and sheep and beef production from grazing.

Location of vehicles using AM station broadcasting signals [PDF]

open access: yes, 1975
Imaginary hyperbolic grid patterns formed by three local AM broadcasting stations were utilized in study. Each hyperbola is defined by constant phase difference between arbitrary signals integrally related to those coming from two stations.

Asymmetric Ligand Field Effects in Electron‐Rich Heterometallic Extended Metal Atom Chain Compounds

open access: yesChemistry – A European Journal, Volume 31, Issue 65, November 20, 2025.
Synthesis of multimetallic compounds with modifiable scaffolding ligands raises questions about the distribution of electronic effects in heterometallic systems. Here we investigate the asymmetry of the substituent effects in a modified 2,2′‐dipyradylamine ligand applied to a heterotrimetallic extended metal atom chain (HEMAC) framework.
