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).

XRD raw data of geological chert of the Algarve basin
May 13, 2026 - A exploração de matérias-primas siliciosas durante o Paleolítico Superior no sudoeste da Península Ibérica
Neto Belmiro, Joana Filipa, 2026, "XRD raw data of geological chert of the Algarve basin", https://doi.org/10.57979/SDLM4E, POLEN DataHub, V1, UNF:6:vjjgQrl2Ilh/1+qEFKI0aw== [fileUNF]
This study utilised X-ray diffraction (XRD) to determine the mineral composition of 23 geological powdered samples of chert from the Algarve region. Samples were analysed using a Bruker AXS D8 Discover XRD with the Da Vinci design, equipped with a Cu Kα source operating at 40 kV and 40 mA, and a Lynxeye 1D detector. Scans were conducted from 3° to...
pXRF 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, "pXRF data of geological and archaeological sample analysis", https://doi.org/10.57979/198LBU, POLEN DataHub, V1, UNF:6:eEaro99lJ/3Q8tmotBp5oA== [fileUNF]
The following data is the result of portable X-ray fluorescence (pXRF) analyses to geological chert samples from southern Portugal, central Portugal and southern Spain, and archaeological chert samples from the Upper Palaeolithic sequence of the archaeological site of Vale Boi (southern Portugal). Data was acquired using the equipment Bruker Titan...
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...
Neural correlates of emotional responses to self-selected music: Evidence from multivariate pattern analysis
Apr 23, 2026 - Repositório Projeto Brainplayback
Alexandre Sayal; Teresa Sousa; César F. Lima; Miguel Castelo-Branco; Inês Bernardino; Bruno Direito, 2025, "Neural correlates of emotional responses to self-selected music: Evidence from multivariate pattern analysis", https://doi.org/10.57979/P4SAYV, POLEN DataHub, V2, UNF:6:aZ1L/d/6W5mnaDZfQLxPbQ== [fileUNF]
Music is a uniquely powerful stimulus for evoking complex and deeply felt emotions. While previous research has identified neural correlates of music-evoked emotional responses, less is known about how these felt emotions are represented in the brain, particularly when elicited by familiar, personally meaningful music. Here, we used a personalized...
