Efficient photocatalytic reactors via 3D printing: SLA fabrication and TiO2 hyb...
Barbosa, ISO; Manrique, Y.A.; Paiva, D.; Faria, JL; Santos, RJ; Silva, CGAdditive Manufacturing (AM) was evaluated as a promising technology for constructing photocatalytic reactors due to its inherent ability to produce complex geometries with high precision and customization. In this work, a 3D structure was designed to achieve a good light distribution inside a cylindrical batch reactor and printed using the stereolithography (SLA) technique. A hybrid material composed of a comme...

Recovery of ergosterol from Agaricus bisporus mushrooms via supercritical fluid...
Almeida C.F.; Manrique, Y.A.; Lopes J.C.B.; Martins, FG; Madalena M. DiasThis work uses the response surface methodology to optimise ergosterol recovery from Agaricus bisporus mushrooms by supercritical fluid extraction. The influence of pressure, temperature, co-solvent use, and solvent-to-mushroom mass ratio was evaluated on yield and extract composition. Considering temperature, pressure, and co-solvent volume percentage, predictive models were regressed for extraction yield, erg...
Development of O/W Pickering Emulsions Stabilized with Leek Leaf Trimmings Usin...
Marques, MP; Sanchez-Salvador, JL; Monte, MC; Blanco, A; Ricardo J. Santos; Madalena M. Dias; Manrique, Y.A.; Margarida BritoVegetable trimmings can be used to stabilize edible O/W Pickering emulsions. The lignocellulosic biomass (LCB) from the leek trimmings was mechanically treated to produce high-yield lignocellulose micro and nanofibrils (LCF) using a high-pressure homogenizer (HPH). Different O/W phase ratios (20/80, 30/70, and 40/60 wt.%) were studied. The use of the micro/nano cellulosic fibers increased the stabilization of t...
3D structured photocatalysts for sustainable H2O2 generation from saccharides d...
Borges, RA; Pedrosa, MF; Manrique, Y.A.; Claudia G Silva; Silva, Adrian; Joaquim Luís Faria; Sampaio, M.J.The possibility of using hydrogen peroxide (H2O2) as a chemical oxidizer or as a green liquid fuel to produce electricity has encouraged both the scientific and industrial communities to investigate green technologies aimed at the sustainability of the production process. In particular, the light-induced synthesis of H2O2 from water and oxygen has attracted significant attention using optical semiconductors.An ...
HaliTeddies: A Vegan Gummy Bear to Inhibit Halitosis Using Carnosic Acid Extrac...
Bessa, A; Barbosa, A; Costa, J; Matysik, J; Alves, M; Marques, M; Manrique, Y.A.HaliTeddies are made of carnosic acid present in rosemary and aim to inhibit the action of halitosis causing bacteria. A need for this product was identified due to the mandatory use of facial masks because of COVID-19, which has had a negative outcome when it comes to breathe malodour. A vegan gummy bear product was selected as the best idea to satisfy this need since it is an appealing approach for a younger ...
Valorization of Ellagic Acid from Chestnut Shell as a Natural Anti-anxiety Food...
Neto, JV; Batista, CA; Franco, BM; Dinis, S; Teixeira, J; Manrique, Y.A.Mental health is on the agenda, especially in pandemic times due to the COVID-19 virus. Nowadays, psychological problems, such as anxiety and depression, have been more discussed and have become even more critical during lockdown. This paper proposes the development process of an innovative product whose active ingredient-ellagic acid, extracted from the chestnut shell-has anxiolytic properties and can be poten...
Antibacterial Finishing of Cotton Bed Sheets using Olive Leaves Extract
Baptista, AM; Shymon, B; Silva, BC; Lopes, CC; Pereira, M; Brandão, S; Manrique, Y.A.The main goal of this project consisted of the conceptualization and development of a product related to the olive tree chemical features to monetize the wastes of the olive fruit exploitation. The most abundant by-product of the olive fruit harvest is the olive leaves, used as the raw material in this project. By following the steps of Chemical Product Design, it was decided to pursue the idea of creating anti...
Design Process and Economic Evaluation of an Innovative Healing Plaster in Gel ...
Querido, AR; Brandão, IR; Marrocos, PH; Loyola, RA; Bastos, Y; Manrique, Y.A.The main goal of this work was to design a new product containing an active ingredient of the Eucalyptus Globulus tree-its essential oil. This work was divided into four steps: analysis of the raw material, chemical product design (needs, ideas, and product selection), manufacture, and economic analysis. After investigating the potential of all the ideas, the product selected was a plaster in gel, named Eucatri...
Strawberry Leaves Extract for Cosmetic Industry
Silva, AP; Rodrigues, B; Bonny, L; Manrique, Y.A.In 2020, Portugal had an average strawberry production of 10 thousand tons, and 15 % was considered strawberry plant residues. This work proposed a new product that uses the compounds extracted from the strawberry residues-stem and leaves, excluding the fruit-as an active ingredient for cosmetic application. Strawberry leaves were extracted with 50 % ethanol. This extract mainly consists of lactic acid, ascorbi...
