Arsonic Acid Functional Polymers Enable Stabilization of Iron Oxide Nanoparticles in Aqueous Solution

open access: yesMacromolecular Rapid Communications, EarlyView.
Arsonic acid containing diblock copolymers are developed to incorporate arsonic acid moieties for surface anchoring to IONPs, along with water soluble PEG blocks to impart colloidal stability in aqueous environments. The resulting polymer‐coated IONPs are evaluated for stability in physiological media and cytocompatibility.

Bimetallic M2B Boride Nanoparticles: A Robust and Recyclable Platform for Dehydration‐Driven Condensation of Aldehydes

open access: yesChemistryOpen, EarlyView.
Metal borides (MBs) emerge as a versatile class of nanomaterials, featuring high stability and bifunctional Lewis‐acidic/basic active sites. Despite these properties, their applications in CN bond formation are less explored. Herein, we report the first systematic use of M2B‐type boride nanoparticles as efficient and magnetically recoverable catalysts

Effect of Fe Doping on the Structural, Morphological, Optical, and Magnetic Properties of Ca2InTaO6 Double Perovskite

open access: yesphysica status solidi (b), EarlyView.
Fe‐doped Ca2InTaO6 double perovskites are synthesized via solid‐state reaction and systematically investigated. Rietveld refinement confirms orthorhombic Pbnm structure, while optical studies reveal a bandgap narrowing from 3.31 to 2.84 eV. Photoluminescence spectra exhibit strong red emission at 671 nm with optimal intensity at 10 mol% Fe ...

Assessing group size and the demographic composition of a canopy‐dwelling primate, the northern muriqui (Brachyteles hypoxanthus), using arboreal camera trapping and genetic tagging

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We combined arboreal camera trapping and non‐invasive genetic tagging to estimate group size in the critically endangered northern muriqui (Brachyteles hypoxanthus) in Brazil's Atlantic Forest. Both methods provided complementary insights into group size and demographic structure, while differing in their cost‐effectiveness and sampling constraints ...

Tailorable Curie Temperature in Zinc Ferrite Nanoparticles With Finely Tunable Induction Heating Profiles Between Room Temperature and 250°C

open access: yesSmall, EarlyView.
A spray‐drying‐based synthesis enables the formation of zinc ferrite nanoparticles with customizable induction heating from room temperature to 250°C by varying the zinc content and postsynthesis annealing temperatures. The aqueous dispersions are colloidally stable and heat up to biologically relevant thresholds. Hence, this approach offers a scalable

Unveiling Regional Disparities: Exploring Cybersecurity Capabilities and Performance Through Systems Theory Approach

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT This study investigates the relationship between cybersecurity capabilities (CCs) and cybersecurity performance (CP) across diverse regional contexts, employing ordinary least squares (OLS) and random forest (RF) regression models. The research highlights how economic, political and cultural factors shape CCs and their impact on CP ...

The History and Ideas of George Herbert Mead's Pragmatism and Its Relevance for Operational Research and Systems Thinkers

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT George Herbert Mead is an oft forgotten or ignored American philosopher who was one of the originators of pragmatism. Today, he is recognised as a creative thinker who has teased out knotty problems that others in the field had not realised were problems. Understanding Mead's analysis has been made difficult because he died prematurely without
