Expedições científicas no século XIX: o universo da ciência e a diversidade cultural
he present paper develops to realize a sociological analysis of the scientific context of the beginning of nineteenth century in Brazil. As a hegemonic discourse, the scientific narrative of the expeditions appears connected with the pictorial art in a ...

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides
A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

The art and science of connecting with consumers
Too often people jump right to the outbound marketing. As a result they often end up trying to push products into people who really don't want the products at all. Effective inbound marketing often results in much more effective - and less difficult - outbound marketing and sales.
