Solvothermal Fabrication of Trimetallic Oxides NCs: Exploring Their Magnetic and Photocatalytic Characteristics

open access: yesNano Select, Volume 7, Issue 4, April 2026.
A trimetallic NiFe2O4/ZnO/Co3O4 nanocomposite is synthesized via a solvothermal route and thermally tuned by post‐annealing. Structural, optical, and magnetic properties evolve systematically with temperature, enabling efficient sunlight‐driven degradation of mixed organic dyes.

ASKAP-EMU

open access: yes, 2009
Next-generation continuum surveys will be strongly constrained by dynamic range and confusion. For example, the ASKAP-EMU (Evolutionary Map of the Universe) project will map 75% of the sky at 20cm to a sensitivity of 10 μJy – some 45 times deeper than NVSS, and is likely to be challenged by issues of confusion, cross-identification, and dynamic range ...

Empirical Literature on Fiscal Multipliers: A Bibliometric Approach, 2002–2023

open access: yesJournal of Economic Surveys, Volume 40, Issue 2, Page 783-820, April 2026.
ABSTRACT This paper reviews the empirical literature on fiscal multipliers through a bibliometric approach, analyzing 337 journal articles published between 2002 and 2023. The articles are categorized based on empirical methodologies, fiscal shock identification strategies, geographic focus, exchange rate arrangements, and macro‐financial regime ...
