A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...

Ultra‐Low Intensity Continuous Wave Laser Ablation Propulsion With Graphene‐Engineered Wood
Graphene delignified wood converts continuous wave laser energy into thrust. Laser propulsion experiments in vacuum reveal the lowest laser ablation threshold intensities and the greatest density‐normalized specific impulse in literature. The results highlight graphene delignified wood as a potential efficient, sustainable, strong, and lightweight ...

El carácter del liderazgo rabínico en la generación de la expulsión
Algunos historiadores judíos han criticado duramente los líderes espirituales e intelectuales de los sefardíes en los años previos a la expulsión de 1492, como pone de manifiesto Norman Roth en una publicación de 1995: “Una característica importante de ...

This work presents a molecular‐level kinetic regulation strategy employing iodoacetic acid (IAA) to simultaneously suppress point defects and solvent inclusion in solution‐grown Cs4PbI6 single crystals. The obtained crystals demonstrate significantly enhanced charge transport properties, enabling X‐ray detectors with high sensitivity, low noise, and ...

Los novicios de la compañía de Jesús: La disyuntiva ante el autoexilio y su estancia en Italia
Cuando, en abril de 1767, se procede a la expulsión de los jesuitas de España, el grupo de novicios que se encontraba en los reconocidos colegios de la Compañía se debate entre el dilema de seguir a estos padres en su exilio o abandonar sus proyectos en ...

Metal‐ion‐coupled self‐assembled layered gels were prepared using a simple sol–gel method, successfully integrating electromagnetic shielding and thermochromic functions into the material. SCa‐1, which exhibits the best overall performance, achieves an electromagnetic shielding efficiency of up to 72.49 dB, while maintaining a visible light ...
