Photomechanical crossroads - Comparing 19th-Century Chromocupography and Charle...

Lopes, David; Machado, Graciela

Chromocupography is a photo-etching technique developed in 19th-century Portugal under the supervision of chemist José Júlio Rodrigues (1843-1923). Very scarce literature is associated with the process, and it doesn’t seem to have been widely used after being made public. At the time, the technique was presented as a variant of Charles Eckstein’s (1840-1913) method, working in Hague, Holland.  Eckstei...


New findings of terrestrial arthropods from the Azorean Islands

Boieiro, Mário; Varga-Szilay, Zsófia; Costa, Ricardo; Crespo, Luis; Leite, Abrão; Oliveira, Raúl; Pozsgai, Gabor; Rego, Carla; Calado, Hugo

The knowledge on taxonomic diversity of arthropods is key to better understanding the biodiversity patterns and processes and guiding sustainable conservation strategies and practices. In the Azores, terrestrial arthropods are relatively well-inventoried following the publication of comprehensive checklists that have been regularly updated. Nevertheless, every year, new species are found as a result of new arri...

Carbon Nanostructures-Silica Aerogel Composites for Adsorption of Organic Pollu...

Lamy-Mendes, Alyne; Lopes, David; Girão, Ana V.; Silva, Rui F.; Malfait, Wim J.; Durães, Luisa

Silica aerogels are a class of materials that can be tailored in terms of their final properties and surface chemistry. They can be synthesized with specific features to be used as adsorbents, resulting in improved performance for wastewater pollutants' removal. The purpose of this research was to investigate the effect of amino functionalization and the addition of carbon nanostructures to silica aerogels made...


Changes in consumer habits in community pharmacies in Portugal during the SARS-...

Pereira, Rúben Duarte; Lopes, David; Mendes, Zilda

Introduction: The sales of over-the-counter (OTC) products in community pharmacies in Portugal is analogous to standard retail business. Several techniques such as cross-selling have been used to increase sales in this segment by encouraging customers to purchase complementary products or services. This technique analyzes transactional data using different methodologies, such as market basket analysis (MBA), wh...

Amine Modification of Silica Aerogels/Xerogels for Removal of Relevant Environm...

Lamy-Mendes, Alyne; Torres, Rafael B.; Vareda, João P.; Lopes, David; Ferreira, Marco; Valente, Vanessa; Girão, Ana V.; Valente, Artur J. M.

Serious environmental and health problems arise from the everyday release of industrial wastewater effluents. A wide range of pollutants, such as volatile organic compounds, heavy metals or textile dyes, may be efficiently removed by silica materials advanced solutions such as aerogels. This option is related to their exceptional characteristics that favors the adsorption of different contaminants. The aerogels...
