O Repositório de Dados de Investigação POLEN DataHub é disponibilizado pela FCCN, serviços digitais FCT – Fundação para a Ciência e a Tecnologia, com o objetivo de promover a abertura e a partilha de dados resultantes de investigação financiada, servindo a comunidade científica nacional.

Esta plataforma está alinhada com a prática da Ciência Aberta e com os princípios FAIR para a gestão de dados de investigação, estando integrada nos serviços abrangidos pelo Programa Nacional de Ciência Aberta e Dados Abertos de Investigação (PNCADAI), financiado pela medida RE-C05-i08 – Ciência Mais Digital, no âmbito do Programa de Recuperação e Resiliência (PRR).

O POLEN DataHub está dividido em duas áreas: a área de Coleções Institucionais (dedicada às entidades aderentes) e a Área Geral (dedicada aos beneficiários FCT sem solução primária: repositório de dados institucional, temático ou Coleção Institucional no POLEN DataHub).

Tabular Data - 8.6 KB - 6 Variables, 184 Observations - UNF:6:gzhLwWuGfm1TPcPzH3OR/A==
Measurements taken to samples analysed through portable X-ray fluorescence (pXRF). The results present the thickness and minimum diameter of each sample to control morphometric heterogeneity with possible impact on the pXRF results.
SEM-EDS data of geological and archaeological sample analysis
May 13, 2026 - A exploração de matérias-primas siliciosas durante o Paleolítico Superior no sudoeste da Península Ibérica
Neto Belmiro, Joana Filipa, 2026, "SEM-EDS data of geological and archaeological sample analysis", https://doi.org/10.57979/K3OBDC, POLEN DataHub, V1, UNF:6:R7fUX8XwI0jeIEztHbKwYg== [fileUNF]
Polished chips of geological and archaeological samples were analysed with a variable pressure Hitachi S3700N SEM, coupled with a Quantax EDS microanalysis system at the HERCULES laboratory (University of Évora). Specifically, the Quantax system is equipped with a Bruker AXS 5010 XFlash Silicon Drift Detector, which offers a spectral resolution of...
