Revista de Historia, 1990 Estudia la formación de clase en Costa Rica entre 1850-1950. La sociedad costarricense, sustentada principalmente en el cultivo del café, da testimonio de una transición “campesino a finquero” en la agricultura, la cual trasformó a un campesino orientado

Advanced Functional Materials, EarlyView.Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Advanced Functional Materials, EarlyView.Blue phosphorescent OLEDs remain limited by poor operational stability. Here, a unified analytical framework integrating transient photoluminescence and magneto‐electroluminescence is developed to correlate intrinsic material photophysics with electrically driven degradation.

Advanced Functional Materials, EarlyView.A dye‐based photoinitiator acting as a structure‐directing element, guides the formation of a cholesteric polymer network that behaves as a chirped photonic structure with dissipative chiral coupling. Photopolymerization freezes a depth‐dependent helical pitch, broadening the Bragg resonance spectrum.

Interface Effects in Ultrathin Silicon on Insulator Films
Advanced Functional Materials, EarlyView.This work establishes a systematic framework to discriminate how bulk and interface phenomena affect charge transport in ultrathin P‐doped silicon‐on‐insulator (SOI) films. For Si films below 15 nm, electrical characterization demonstrates that interface states drive charge transport, shifting the metal‐insulator transition (MIT) critical dopant ...

Anales de Geografía de la Universidad Complutense, 2007 La Independencia de la América Hispánica inauguró una nueva etapa en las relaciones entre España y las naciones aparecidas al comienzo del siglo XIX. La normalización diplomática se produjo en la segunda mitad de esa centuria paralelamente a un momento ...

Advanced Healthcare Materials, EarlyView.Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.
