Solvent-Based Elimination of Organic Matter from Marine-Collected Plastics
(MDPI, 2021-07-20)
The physical-chemical characterization of plastic litter from the marine environment requires the prior removal of the biofouling attached to their surface without causing any degradation in the polymer. The absence of a ...
On the pyrolysis of different microalgae species in a conical spouted bed reactor: Bio-fuel yields and characterization
(Elsevier B.V., 2020-05-20)
The aim of this work was to study fast pyrolysis of three microalgae species in a continuous bench-scale conical spouted bed reactor at 500 °C. Bio-gas, bio-oil and bio-char yields have been determined and characterized ...
Encapsulation of Oleuropein in Nanostructured Lipid Carriers: Biocompatibility and Antioxidant Efficacy in Lung Epithelial Cells
(MDPI, 2020-05-06)
Oxidative damage has been linked to a number of diseases. Oleuropein (OLE), a natural occurring polyphenol from olive leaves (Olea europaea L.), is known to be a potent antioxidant compound with inherent instability and ...
Mineralogical Characterization of Slags from the Oiola Site (Biscay, Spain) to Assess the Development in Bloomery Iron Smelting Technology from the Roman Period to the Middle Ages
(MDPI, 2020-04-03)
The Oiola archeological site, located in the mining complex of La Arboleda (Biscay, North Spain) was an important iron smelting center from the Roman Period to the Middle Ages and even in more current times (19th–20th ...
Threading Performance of Different Coatings for High Speed Steel Tapping
(MDPI, 2020-05-10)
Threading holes using tapping tools is a widely used machining operation in the industry. This manufacturing process involves a great tool immersion in the part, which involves both friction and cutting. This makes the use ...
Association Among Polyphenol Intake, Uric Acid, and Hyperuricemia: A Cross-Sectional Analysis in a Population at High Cardiovascular Risk
(Wiley, 2022-10)
Background Dietary polyphenol intake has been associated with a decreased risk of hyperuricemia, but most of this knowledge comes from preclinical studies. The aim of the present study was to assess the association of the ...
Las ciudades educadoras ante la segregación escolar: caminando hacia el desarrollo sostenible
(Universidad de Salamanca, 2022)
El quehacer fundamental de las Administraciones y de la clase política en general, es mejorar la calidad de vida de la ciudadanía. En lo que se refiere al Objetivo de Desarrollo Sostenible (ODS) número 4, las administraciones ...
Transcriptomic meta-analysis reveals unannotated long non-coding RNAs related to the immune response in sheep
(Frontiers Media, 2022-11)
Long non-coding RNAs (lncRNAs) are involved in several biological processes, including the immune system response to pathogens and vaccines. The annotation and functional characterization of lncRNAs is more advanced in ...
How Reliable Are Modern Density Functional Approximations to Simulate Vibrational Spectroscopies?
(American Chemical Society, 2022-06-30)
We show that properties of molecules with low-frequency modes calculated with density functional approximations (DFAs) suffer from spurious oscillations along the nuclear displacement coordinate due to numerical integration ...
Stars, combs and bottlebrushes of elastic single-chain nanoparticles
(Elsevier, 2022-10)
Hierarchical self-assembly of structural elements gives rise to superstructures often with outstanding properties when compared to individual elements, as first observed in nature. While folding of individual synthetic ...
