Advanced Functional Materials, EarlyView.Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret
Advanced Functional Materials, EarlyView.Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Advanced Functional Materials, EarlyView.We report a unique color‐sensing phenomenon of a TiO2/SbSI:Sb2S3 device utilizing X‐ray absorption. Based on the revealed penetration and adsorption of water onto TiO2, we successfully improved the color response speed and sensitivity by incorporating a hydrophilic polymer interlayer, thereby opening up opportunities for photodetection applications ...

Advanced Functional Materials, EarlyView.Inspired by lung alveolar architecture, a dual‐templating strategy combining CO2 bubble and ice templating creates mechanically robust super‐macroporous hydrogels with highly interconnected transport pathways. The resulting material achieves 3.37× faster moisture sorption and 1.72× higher solar‐driven water release than single‐templated counterparts ...

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies
Advanced Functional Materials, EarlyView.Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Sílex, 2019 Este artículo explora las ideas de Arne Naess sobre el cambio de paradigma entre una ética antropocéntrica hacia una ética biocéntrica en el marco de una ecología profunda que contrasta con una superficial. Estudiamos algunos casos en América Latina para establecer el vínculo entre el colonialismo y la depredación ecológica, así como la deshumanización
