Engineering Pd Nanostructures on Hierarchical Flower‐Like Alumina Nanosheets for the Efficient Catalytic Reduction of 4‐Nitrophenol

open access: yesNano Select, EarlyView.
Palladium nanocubes and nanoparticles supported on nanosheet‐assembled alumina (NA‐Al2O3) were investigated as highly efficient catalysts for the reduction of 4‐nitrophenol. Systematic comparisons highlight the roles of nanoparticle morphology and support structure, with PdNC@NA and PdNP@NA showing superior activity and stability over commercial Al2O3 ...

Religion and Regulatory Variance: Halal Regimes as Islamic Public Administration

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT One quarter of humanity are Muslims, for whom halal food is an everyday consideration. The global food system has made assessing food products nearly impossible for consumers, requiring elaborate regulatory regimes. This article analyzes halal regulation as a notable example of Islamic public administration (IPA), as an application of ...

Pesticide exposure of operators during mixing and loading a drone: towards a stratified exposure assessment

open access: yesPest Management Science, EarlyView.
Operators are exposed to concentrated formulation during mixing of pesticide into the nurse tank and to an in‐use dilution during loading the drone; stratification of exposure for mixing and loading would inform the exposure assessment approach by applying the appropriate dermal absorption considerations.

Thermo‐Chemically Modified Silk Scaffolds Reveal Niche‐Driven Regulation of Hematopoiesis and Fibrosis

open access: yesSmall, EarlyView.
We introduce a versatile 3D platform that recreates key physical and biological features of the human bone marrow. By integrating tunable silk biomaterials, stromal cells, and human hematopoietic progenitors, the model captures both healthy and diseased microenvironments, analysis of blood formation, and its disruption in pathological conditions ...

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport

open access: yesSmall Structures, EarlyView.
Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The
