Abstract: RESUMO: A Revista de Antropologia, especialmente em sua primeira fase, publicou predominantemente estudos de etnologia. Faço aqui um rápido levantamento desse período inicial, sugerindo que esses estudos apresentam boas pistas para se escrever uma história da etnologia no Brasil. Lembro também que o jubileu da Revista coincidiria com o 90 o aniversário de seu criador, Egon Schaden. PALAVRAS-CHAVE: etnologia, história da antropologia, grupos indígenas brasileiros.

“…2). Although these materials exhibited very low densities (0.17 g/cm 3 for COF-108), they showed high thermal stabilities and high porosity due to the robust network formed by covalent bindings (C-C, C-O, C-B, and B-O). Interestingly, the experiments carried out during the synthesis process of these 3D COFs revealed that both thermodynamic and kinetic factors are decisive to achieve the crystallization of the materials, being necessary a suitable correspondence among these two parameters [21].…”

“…The generation of stable, robust, ordered and highly accessible porous materials with associated functionalities in their framework remains a crucial topic in material science when searching advanced solids for adsorption, separation, catalysis, energy storage, sensors, electronic or photoluminescence devices [1,2]. In all cases, homogeneous porous distribution and functional networks are indispensable requirements to establish suitable and efficient host-guest interactions and confinement effects [3]. For the preparation of this type of ordered porous materials, the use of suitable building blocks is fundamental to construct various networks through convenient synthesis methodologies [4,5].…”
