DE COMUNIDAD LOCAL A COMUNIDAD MUNDIAL
Abierta. Anuario de investigación, 2015 Para entender el fenómeno de crecimiento e influencia de las comunidades virtuales católicas fue necesario analizar las necesidades y los comportamientos de la audiencia. Se descibrió que el sexo femenino poseee mayor participación y representatividad. La tolerancia a la crítica permite lograr el objetivo de generar conversación entre los usuarios.

Advanced Materials, EarlyView.Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

Advanced Materials, EarlyView.The seminal transformation of a 2D‐COF (SURFCOF‐IMDEA1) into a 2D porous COF (SURFCOF‐IMDEA2) on Au(111) by a sequential C‐C coupling and ladderization triggered by thermal annealing steps at increasing temperatures is reported. Abstract The development of covalent organic frameworks (COFs) is currently a primary objective in materials science, taking ...

Advanced Materials, EarlyView.Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the
