Debt sustainability in historical perspective: The role of fiscal repression [PDF]

open access: yes
This article examines the debt history of two contenders for European hegemony: 16th-century Spain and 18th-century Britain. We analyze their fiscal behavior using measures of overborrowing and fiscal policy functions. Our results suggest that stringency

Durable Bio‐Based Nanocomposite Coating on Urinary Catheters Prevents Early‐Stage CAUTI‐Associated Pathogenicity

open access: yesAdvanced Materials Interfaces, EarlyView.
A stable bio‐based nanocomposite coating for urinary catheters is developed using a simple, environmentally‐friendly sonochemical process. The coating, integrating antimicrobial, antibiofilm, and antioxidant properties, effectively tackled multiple early‐stage pathogenic factors associated with catheter‐associated urinary tract infections.

Antifouling Surface‐Attached Hydrogel Nanocoatings Redefined: Green Solvent‐Based, Degradable, and High‐Performance Protection Against Foulants

open access: yesAdvanced Materials Interfaces, EarlyView.
An ultrathin surface‐attached hydrogel coating is introduced that, unlike the best antifouling coatings so far, consists of hydrophilic, non‐charged, green solvent‐based monomers. It effectively renders the surfaces of medical devices stealth toward proteins, a clinical strain of MRSA and blood while offering on‐demand degradability to regenerate the ...

Enhancing Environmental Stability and Transparency of Glass Coatings Using Silica Nanoparticles in the Sol‐Gel Process

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents a novel silica‐based sol‐gel coating enhance with silica nanoparticles to protect glass surfaces. By reducing formulation acidity and improving resistance to environmental alteration—especially with 50 nm particles and double‐dip application—the method creates a gentle yet effective protective barrier.

Has Austerity Worked in Spain? [PDF]

open access: yes, 2015
Since 2011 Spain has pursued a set of economic policies for recovery based on internal currency devaluation, labor market reform, fiscal consolidation, and structural and deregulatory reforms such as the Market Unity Law, which are based on the idea of ...

Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite

open access: yesAdvanced Materials Technologies, EarlyView.
Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication
