Industrial agglomerations and wage gradients: the Spanish economy in the interwar period [PDF]
This paper gives new evidence on the relationship between integration and industrial agglomeration in the presence of scale economies, by testing directly one of the predictions that can be derived from Krugman (1991), that is, the existence of regional ...

Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials
Advanced Materials Technologies, Volume 10, Issue 11, June 5, 2025.This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

Industrial Property Institutions, Patenting, and Technology Investment in Spain and Mexico, c. 1820-1914. [PDF]
This paper explores the nature and implications of nineteenth century patent law in two late-industrializing countries: Spain and Mexico. Both inherited earlier ancien regime monopoly practices, both adopted aspects of modern, codified patent systems in ...

Advanced Optical Materials, EarlyView.Advanced anodic aluminium oxide (AAO) nanostructures incorporate interconnections between the vertical pores, forming a 3D‐AAO nanonetwork that functions as a Bragg reflector. By varying the periodicity of the transverse channels, the light‐matter interaction can be tuneable to enhance their emissivity and passive radiative cooling performance across ...

Advanced Optical Materials, EarlyView.Theoretical lessons are key for molecules presenting an inverted singlet‐triplet excited state (e.g. S1 and T1) energy difference. This perspective provides a snapshot of the role played by calculations in last years, not only to anticipate experimental findings but also for driving high‐throughput virtual screenings, as well as the main challenge to ...

Advanced Optical Materials, EarlyView.Complexes [PtII(Cbz‐C^C*bzim/im)(L^L)], bearing carbazole‐appended cyclometalated NHCs, show bright phosphorescence, peaking from the blue to the yellowish–green spectral range depending on the carbene, L^L, and doping concentration. Non‐doped OLEDs using 1A or 3A (L^L = acac or P^O2) reach the best performances (Von: 2.99 V, 2.55 V; Lmax: 39208, 25837

Advanced Optical Materials, EarlyView.A strong interaction between the five‐armchair graphene nanoribbons (GNRs) and the encapsulating single‐walled carbon nanotubes is identified. A reduction of the bandgap of the hybrid structure as well as additional proof for the single H‐terminations of the GNRs are confirmed through a combination of optical absorbance spectroscopy and density ...

Spherical and Aspherical Lenses for Boosting the Performance of Terahertz Imaging Systems
Advanced Photonics Research, EarlyView.This study investigates the enhancement of terahertz (THz) detection through the terajet effect using mesoscale dielectric lenses of various geometries. Spherical, aspherical, and cubic polytetrafluoroethylene lenses are evaluated at 0.15 and 0.3 THz, demonstrating significant improvements in responsivity and noise reduction.
