Advanced Materials, EarlyView.Photocatalytic transfer hydrogenation is achieved over a multivalence‐state palladium photocatalyst, in which protons generated from photocatalytic water splitting are added to unsaturated double bonds. The operando light‐induced Electron Paramagnetic Resonance (EPR) spectroscopy confirms the synergistic action between Pd single atoms and nanoparticles,

Patrimonio + Turismo = ¿Desarrollo?
PASOS Revista de Turismo y Patrimonio Cultural, 2003 Como dicen algunas páginas web, este texto está en construcción, no tanto porque esté inacabado como por su propia naturaleza como instrumento de reflexión y trabajo, que debería permitir discrepar, debatir las ideas ex-puestas, y si se considera que tienen algún interés, incorporarlas y contrastarlas, global o parcialmente, a los procesos de ...

Electrochemical Modulation of Hole Extraction in NiO/Perovskite Bilayers
Advanced Materials Interfaces, EarlyView.The influence of hole depletion/accumulation on the hole extraction is evaluated in NiO/perovskite bilayers by transient spectroelectrochemical measurements. Metal‐halide perovskite thin films with different valence band positions are prepared, and the influence of band offset on the hole extraction kinetics is studied.

TIC como apoyo del soporte social al enfermo crónico y su cuidador : Aproximación al estado del Arte [PDF]
Event Encuentro Nacional de Investigacion y Desarrollo ENID 2013
1st ed, Vol 1, pages 1-7 (2013), 2022 The current approach is carried out in order to have an overview of the level of inclusion and the participation of ICTs in social support and support for vulnerable populations suffering from chronic diseases. The inclusion was made through a bibliographic review, this being the basis for the collection of data and pertinent information.

Microfluidic Spinning of PEDOT:PSS Microfibers for Nerve Guidance Conduits
Advanced Materials Technologies, EarlyView.This publication explores the fabrication of microfluidically spun PEDOT:PSS microfibers for conductive nerve guidance conduits (NGCs). It details the spinning process, fiber characterization, and biocompatibility assessment. The study highlights the fibers' mechanical and electrical properties, non‐cytotoxicity, and potential for nerve regeneration or
