Supraparticles Composed of Graphitic Carbon Nitride Nanoparticles and Silica‐Supported Horseradish Peroxidase as Customizable Hybrid Catalysts for Photo‐Biocatalytic Cascade Reactions in Continuous Flow

open access: yesAdvanced Functional Materials, EarlyView.
Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

Exploring the Spatial Distribution and Location Choice of Companies in a Hungarian Agglomeration

open access: yesStudia Regionalne i Lokalne
Globalisation has led to the dominance and geographical expansion of urban areas. Companies consider a complex set of criteria when deciding on their locations, including the agglomeration area and the presence of similar companies or related businesses.

Product differentiation in a spatial Cournot model with asymmetric demand [PDF]

open access: yes
This paper considers a spatial discrimination Cournot model with asymmetric demand. We use the geographical interpretation of the linear market and introduce differentiated products.

Complex Cryptographic and User‐Centric Physically Unclonable Functions Enabled by Strain‐Sensitive Nanocrystals via Selective Ligand Exchange

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.

Delineating African cities (large urban regions) to compare them within global urban networks

open access: yesCybergeo
An important issue for Africa is evaluating cities' capacities to leverage global networks effectively to foster local development. However, this evaluation is complicated by the absence of a unified framework and criteria, making it difficult to compare

Agglomeration and Tax Competition [PDF]

open access: yes
Tax competition for a mobile factor is different in "new economic geography settings" compared to standard tax competition models. The agglomeration rent which accrues to the mobile factor in the core region can be taxed.

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Can information asymmetry cause agglomeration? [PDF]

open access: yes
The modern literature on city formation and development, for example the New Economic Geography literature, has studied the agglomeration of agents in size or mass.

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

open access: yesAdvanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

open access: yesAdvanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.
